The rising costs of essentials like housing, food, and soaring utilities bills, have forced many individuals and families in QLD to make difficult financial choices, often compromising on safety measures that could prevent devastating house fires.

Cost Of Living vs Household Fire Safety

One of the primary casualties of heightened cost of living is the ability to invest in quality home maintenance and fire safety equipment. With limited budgets, individuals may opt for cheaper alternatives or delay essential repairs, inadvertently increasing the risk of fire hazards. Overloaded electrical circuits, faulty wiring, and neglected appliances become ticking time bombs in homes where financial constraints take precedence over safety concerns.

Interconnected Smoke Alarms And The Cost Of Living

Additionally, the pressure to cut corners extends to everyday items such as household interconnected smoke detectors and fire blankets. Outdated or poor quality interconnected smoke detectors may malfunction or prove ineffective in the crucial moments when swift action is required. Studies have shown a direct correlation between subpar fire safety equipment and increased property damage and casualties during house fires. Quality ZEN interconnected smoke detectors contain a 10-year lithium battery which provides a cost saving over the life of the product – unlike conventional 9V battery smoke alarms – you don’t have to buy a multitude of new batteries and swap them out every year. Our ZEN interconnected smoke alarm bundle packs also offer free shipping Australia-wide (another cost saving) and include a free smoke alarm remote control (RRP $34.95).

NSW Fire and Rescue offer a similar free service in that they will attend your home and check that you have working smoke alarms, that they are in good working condition, and are installed in suitable areas. Contact the QLD Fire Department or NSW Fire and Rescue for further information and to make a booking.

In a recent article published in Queensland’s The Courier Mail newspaper, University of Wollongong fire expert Dr Owen Price said the rising cost of living was likely affecting fire risk within homes as many of the steps people could take to protect themselves required money.

“A lot of people realise they are at risk, but they often don’t do anything about it and when cost of living comes in it’s often lowest on people’s priorities,” he said.

Cash strapped families also tended to live in cheaper, older housing, which was more vulnerable to fire, Dr Price said.

The stress induced by financial strain can also lead to a decrease in mental well-being, which further compounds the risk of fire incidents. Anxiety and fatigue can contribute to forgetfulness, neglect, and even a diminished ability to respond promptly to emergency situations. In households grappling with cost of living pressures, the mental toll may impair the residents’ ability to maintain a vigilant stance on fire prevention.

Cost Of Living Crisis And Fire Safety – Summary

The cost-driven choices people make during periods of financial constraint may inadvertently compromise their fire safety and well-being. The repercussions of these decisions are profound. House fires, once ignited, can escalate rapidly, and inadequate fire safety measures can only exacerbate the situation. The resulting loss of property and, tragically, sometimes lives, underscores the urgency of addressing the intricate balance between cost of living pressures and overall home fire safety, including quality interconnected smoke detectors.

ZEN Interconnected Smoke Alarms

Smoke alarms are essential safety devices that detect the presence of smoke in the air and warn people of a potential fire. Photoelectric interconnected smoke detectors, in particular, are becoming increasingly popular due to their effectiveness in detecting smoldering fires and minimizing false alarms But have you ever wondered how photoelectric interconnected smoke detectors are manufactured to to meet the highest standards of quality and safety? Manufacturers of a interconnected photoelectric smoke alarm need to ensure that their products are safe, reliable, and effective – this is where an ISO 9001 Quality Management System comes into play.

What Is An ISO 9001 Quality Management System? (QMS)

ISO 9001 is a globally recognized standard for quality management systems. ISO stands for International Standards Organisation. It provides a framework for organizations to establish and maintain processes that ensure consistent product quality. ISO 9001 is an important indicator of a company’s commitment to quality and customer satisfaction – it covers all aspects of an organization’s operations, including design, development, production, delivery, and support. Has your interconnected smoke alarm has come from an ISO 9001 accredited facility? (ZEN Smoke Alarms do!).

The commercial production of interconnected smoke detectors involves sourcing high-quality materials, assembling the components, and then testing the finished product for quality and safety. ISO 9001 requires manufacturers to establish and document clear processes for sourcing these materials and assembling the product, as well as procedures for testing and inspecting the final product.

Testing is a crucial part of the manufacturing process for photoelectric interconnected smoke detectors. ISO 9001 requires manufacturers to establish rigorous testing procedures to ensure that every device meets the required safety standard (Australian Standard 3786:2014). This includes testing for sensitivity to smoke, false alarms due to humidity and temperature changes, and battery life. The testing processes must be uniform and ongoing, to ensure consistency and reliability of the finished product.

ISO 9001 certification also requires manufacturers to continuously monitor and improve their processes to ensure consistent product quality. This involves regularly reviewing and analyzing data to identify areas for improvement, and implementing changes to optimize the manufacturing process. In addition to periodic internal audits, our ZEN smoke alarm manufacturing facility is also audited annually by an external third party agency to ensure the required processes remain in place and continue to be effective.

Manufacturers must also have processes in place to ensure that the interconnected smoke detector is delivered to customers safely and effectively. This means that the fire alarms are packaged correctly and that they arrive at their destination without damage. Manufacturers must also ensure that customers can install and use the interconnected smoke detectors correctly.

One of the key benefits of ISO 9001 is the emphasis on customer focus. This means that manufacturers of an interconnected smoke alarm must prioritize meeting the needs and expectations of their customers. ISO 9001 requires manufacturers to collect and analyze customer feedback to identify areas for improvement and to ensure that customer requirements are met. We provide a courtesy follow-up phone call post-purchase to help meet this objective.

ISO 9001 Interconnected Smoke Alarm Summary

In conclusion, manufacturing photoelectric interconnected smoke detectors is a complex process that requires precision, attention to detail, and a commitment to quality and safety. ISO 9001 accreditation plays a crucial role in ensuring that every step of the process is documented, monitored, and continuously improved to meet the highest standards of quality and safety. By choosing an interconnected photoelectric smoke alarm manufacturer that is ISO 9001 accredited, you can have confidence that the interconnected smoke detectors in your home or building are of the highest quality and will provide reliable protection for years to come.

ZEN Interconnected Smoke Alarms

Queensland was rocked by another devastating house fire tragedy earlier this month when police confirmed that five young brothers and their 34-year-old father died in a house blaze on Russell Island, off Brisbane’s Redland Bay. Emergency services rushed to the home on Todman Street just after 6am on Sunday 8th August to find the two-storey house fully engulfed, with two neighbouring properties also alight. A 21-year-old woman thought to have been inside the house when the fire broke out managed to escape with injuries.

The Queensland Fire and Emergency Services Assistant Commissioner, John Cawcutt, said the blaze was “one of the worst fires we’ve had for a long time”. Fire and Emergency Services Minister Mark Ryan also said the fire was a great tragedy. “Of course a very sad day for Queenslanders,” he said. “Our hearts break for those involved in the tragedy. It seems a tragic loss of life”. A forensic investigation is currently underway to determine how the fire started, and why the smoke alarms did not activate.

A close family friend issued a harrowing plea to all Australians on the behalf of the Children’s surviving mother, stating that she ‘just wants the world to know – check your smoke alarms and hold your babies’.

In terms of sheer loss of life from a single domestic house fire, the Russell Island fire tragedy is second only to the August 2011 Logan house fire, which was Australia’s deadliest house fire, causing the death of 11 family members. A coronial inquest could not establish the exact cause of that blaze but a coroner found there was a ‘reasonable prospect’ that all or some of the victims could have escaped if smoke alarms had been working. That tragedy led to the introduction of new QLD laws for photoelectric interconnected smoke detectors inside every bedroom, hallways outside the bedrooms, and on every level of Queensland homes.

Why Didn’t The Smoke Detectors Activate

In The Russell Island House Fire?


The rented two storey Queenslander home allegedly had smoke detectors installed, however the female survivor of the blaze said she didn’t hear any smoke detectors activate, adding that concerns had previously been expressed about them. Immediately after the fire it remained unclear why the fire alarms didn’t activate and whether they were in working order. ‘With a fire of that intensity it will be difficult to know whether there were smoke alarms present or not but that will be part of the investigation,’ Queensland Fire and Emergency Services Deputy Commissioner Joanne Greenfield said. It is understood the home was transported to the site around 2017. ‘So thinking about the legislation that was in place at that time it would have required one hardwired smoke alarm, that’s if it was following the legislation,’ QLD Fire and Emergency Services Commissioner Leach said.

Development in the Russell Island house fire – why didn’t the smoke alarms activate?

QLD Interconnected Smoke Alarm Laws

From 1st January 2022, all properties being sold or leased for rent in Queensland were required by QLD law to have smoke alarms installed as per below (on 1st January 2027 the law is being extended to cover all QLD homeowners and occupiers, irrespective of whether the property is being sold or rented out).

QLD Legal Smoke Alarm Requirements

Smoke alarms in a domestic QLD property must:

  • be photoelectric (AS 3786-2014); and
  • not also contain an ionisation sensor
  • be less than 10 years old from manufacture date
  • operate correctly when tested
  • be interconnected with every other smoke alarm in the dwelling so all activate together
  • be either hardwired or powered by a non-removeable 10-year battery

Where Must Interconnected Smoke Alarms Be Installed?

In QLD, interconnected smoke detectors must be installed on each storey:

  • inside every bedroom
  • in hallways which connect the bedrooms and the rest of the dwelling
  • if there is no bedroom on a storey, then at least one interconnected smoke alarm must be installed in the most likely travel path to exit the dwelling.

QLD Smoke Alarm Laws For Rental Properties

In addition to the above, rental property managers and landlords are required by QLD law (QLD Fire and Emergency Services Act 1990) to test and clean interconnected smoke detectors and replace any flat or nearly flat batteries within 30 days before the start of a tenancy. This also includes a renewal tenancy. The tenant must also test and clean each smoke alarm in the dwelling at least once every 12 months. If the tenant is aware a smoke alarm in the dwelling has failed, the tenant must advise the lessor as soon as possible.

Postscript Update – April 2024

The landlord was charged and fined under the QLD Fire and Emergency Services Act 1990 after she admitted failing to install compliant photoelectric smoke alarms in the rental property.

The interstate landlord claimed to be unaware of the changes to QLD’s smoke alarm legislation.

“It’s absolutely no excuse that she failed to keep abreast of the laws required of an investment property owner in having the premises legally wired with smoke detectors after January 2022,” Magistrate Deborah Vasta said. Ms Vasta told the court that the landlord had failed to comply with safety legislation and a coronial inquest into the six deaths was still yet to occur.

“There’s no evidence about whether two smoke alarms that were there were working or not,” she said.

Detectives are continuing their investigation following the fire and a final report will be given to the coroner in the near future.

ZEN Interconnected Smoke Alarms

A new Australian Standard for smoke alarms, Australian Standard 3786:2023, was published by the Standards Australia Committee on February 17, 2023. This standard supersedes the previous version, Australian Standard 3786:2014.

It is common for Australian Standards to undergo updates, amendments, and supersessions over time. Australian Standard 3786, first released in 1990, has undergone at least 10 updates and reissues since its inception.

Why New Australian Standard 3786:2023?

Several reasons led to the issuance of the new Australian Standard 3786:2023

Technological Advancements In Interconnected Smoke Alarms

The standard needed to incorporate emerging smoke alarm technologies and evolving existing technologies. This ensures the standard remains relevant and reflects the current technology available in the market. For example, the new standard now includes provisions for WiFi smoke alarms, interconnected smoke detectors, and dual sensor smoke alarms that combine a carbon monoxide detector.

Smoke Alarm Safety Considerations And New Testing Protocols

Safety is a crucial aspect of the standard. As new fire risks are identified and existing ones are better understood, the standard has been updated to address these concerns. Clearer guidelines for the safe usage of smoke alarms and associated testing protocols have been provided.

Harmonization With International Smoke Alarm Standards

In a globalized world, aligning standards across different countries and regions is essential for interoperability and mutual recognition of products. Australian Standard 3786:2023 is now aligned with the International Standard ISO 12239:2021 for smoke alarms using scattered light, transmitted light, or ionization.

Smoke Alarm Stakeholder Feedback And Continuous Improvement

The development of Australian Standard 3786:2023 involved an iterative process that considered feedback from users, stakeholders, and experts. Committee members included the National Fire Industries Association, Australian Building Codes Board, Property Council of Australia, CSIRO, and the Fire Protection Association Australia.

Differences Between AS 3786:2023 And AS 3786:2014 ?

The new Australian Standard 3786:2023 introduces several key changes compared to the old Australian Standard 3786:2014:

– Recognition of combination and multi-criteria smoke alarms, which provide multiple fire sensors within a single housing.
– Permission for the inclusion of a sensor unrelated to smoke detection, such as a carbon monoxide sensor, to create a dual carbon monoxide detector and smoke alarm product.
– Introduction of new requirements for mains-powered smoke alarms, temporary disablement facility, smoke alarms using radio frequency links, and assessment for wall-mounted smoke alarms.


Do I Need To Replace My Existing AS 3786:2014 Compliant Smoke Alarms,

With New Smoke Alarms Compliant To AS 3786:2023?

If you currently have smoke alarms compliant with Australian Standard 3786:2014, you are not required to replace them because of the release of new Australian Standard 3786:2023. Compliance with a specific Australian Standard only becomes a legal requirement when it is referenced in legislation by the Australian government or other regulatory agency. At the time of writing this article, fire safety legislation in Queensland and the National Construction Code 2022 still reference Australian Standard 3786:2014. Therefore, legal compliance remains unchanged, and you should continue to comply with Australian Standard 3786:2014. It’s important to note that regardless of changes to the standard, smoke alarms should be replaced if they fail to operate or are older than 10 years from the manufacture date. For replacement, photoelectric interconnected smoke detectors are always recommended.

ZEN Interconnected Smoke Alarms

Australia has experienced a surge in the adoption of lithium-ion battery technology in recent times, and QLD is no exception. These small, lightweight, and versatile batteries have revolutionized various aspects of modern life, powering everything from smartphones to e-scooters, e-bikes, and home renewable energy storage systems. However, this remarkable advancement is accompanied by a concerning increase in lithium-ion battery fires in homes across Queensland.

QLD Lithium-Ion Battery Fires Increasing Significantly

Data compiled from each Australian state fire department reveals that since 2021, more than 450 fires related to lithium-ion batteries have occurred in Australia, with 157 of them in Queensland alone. Improper battery charging practices have been identified as one of the primary causes behind these alarming incidents. When consumers use incompatible battery chargers or leave their electronic devices, like e-scooters, charging unattended for extended periods, overcharging and overheating of the lithium-ion battery can occur.

What Causes Lithium-Ion Battery Fires?

Another significant cause of lithium-ion battery fires is manufacturing defects in either the battery charger or the battery itself. Poor quality control during production can lead to internal faults, increasing the risk of overheating and fire. Additionally, improper storage or transportation of lithium-ion batteries can cause short circuits and subsequent fires. To minimize this risk, it is crucial to avoid purchasing cheap lithium-ion batteries and chargers from unregulated online marketplaces and to opt for original equipment manufacturer (OEM) products.

The nature of use for e-scooters and e-bikes exposes their batteries to rough handling and environmental elements, making them susceptible to damage that can result in internal short-circuits and fires. Even minor physical damage to the battery’s protective casing can create a pathway for ‘thermal runaway’, triggering a catastrophic fire event. When lithium-ion batteries fail, they undergo thermal runaway, leading to the violent bursting of battery cells, the release of toxic, flammable, and explosive gases, and an intense, self-sustaining fire. These fires are challenging to extinguish with water or regular fire extinguishers, and they can easily reignite after being put out.

Are The Lithium Batteries Dangerous In My Smoke Alarm?

This is a good question and one that needs to be asked. It would be ironic if smoke alarms designed to detect smoke and save lives were actually powered by lithium-ion batteries that are a major cause of house fires! Fortunately the same fire risk in lithium-ion batteries is not present in the 10-year lithium batteries sealed inside your smoke alarm. Why? The two small, 3V lithium batteries inside your smoke alarm are non-replaceable and non-rechargeable and are designed to deplete slowly and steadily over a 10-year lifespan. They do not undergo the repeated energy discharge / recharging process that much larger lithium-ion batteries do, and are not subjected to the same external forces of bumping, knocking and damage that scooters, e-bikes and other devices experience – this eliminates the associated fire and thermal runaway risk. Additionally, all smoke alarms sold in Australia should comply with Australian Standard 3786:2014 which incorporates stringent electrical testing of the smoke alarm itself, prior to sale.

Interconnected Smoke Alarm Battery Safety

It is essential that all interconnected smoke detectors purchased are certified to Australian Standard 3786:2014 and bear the official Australian Standard mark and the Regulatory Compliance Mark (RCM). The RCM signifies compliance with Australian electrical safety and electromagnetic compatibility regulations, as outlined in Australian Standard 3820:2020. By avoiding cheap knock-offs lacking these marks, consumers can ensure they are purchasing legitimate, safe electrical appliances.

Top Tips For Preventing Lithium-Ion Battery Fires

  1. Use Manufacturer-Approved Chargers:
    • Always use the charger and power adapter that comes with your device or is recommended by the manufacturer.
  2. Monitor Charging:
    • Charge batteries in a place where you can keep an eye on them and avoid charging overnight or when you’re not at home.
  3. Avoid Overcharging:
    • Unplug devices once they are fully charged to prevent overheating and reduce wear on the battery.
  4. Store Batteries Safely:
    • Keep batteries in a cool, dry place, away from direct sunlight and flammable materials.
  5. Avoid Physical Damage:
    • Handle batteries with care to prevent drops, punctures, or any form of physical damage that could lead to internal short circuits.
  6. Check for Damage:
    • Regularly inspect batteries for signs of damage, swelling, or leakage. Stop using and properly dispose of any damaged batteries. This is particularly important for any transportation or mobility devices such as e-bikes or e-scooters.
  7. Keep Away from Extreme Temperatures:
    • Avoid exposing batteries to high or low temperatures, which can cause damage and increase the risk of fire.
  8. Don’t Mix Batteries:
    • Do not use old and new batteries, or batteries of different types and capacities, together in the same device.
  9. Proper Disposal:
    • Do not throw lithium-ion batteries in the regular wheelie bin to prevent potential fires. Ensure that you tape the terminals of used batteries with clear sticky tape before taking them to your local Council’s drop off point / recovery centre.
  10. Install Interconnected Smoke Detectors:

Summary

The increase in lithium-ion battery fires necessitates a collaborative effort from manufacturers, regulators, and users to address this growing concern. While the advantages of lithium-ion batteries are undeniable, safety risks demand immediate attention. By enhancing safety regulations, improving manufacturing standards, and promoting responsible usage and recharging practices, Australia can fully embrace the lithium-ion battery revolution while ensuring a safer and more sustainable future for all.

Smoke Alarm Laws In Western Australia

Smoke alarm laws in Western Australia are derived from the;

W.A Building Regulations 2012 (division 3) which enshrine Building Code of Australia smoke alarm requirements.

W.A Building Regulations 2012 – Smoke Alarms

In 1997, 240v hardwired smoke alarms became compulsory in Western Australia for all newly constructed residential buildings (or residential building extensions). From 2009 onwards this was extended to also include all existing residential buildings, prior to their transfer of ownership, rent or hire.

In Western Australia smoke alarms must;

  • be positioned according to the requirements of the Building Code of Australia
  • comply with Australian Standard 3786:2014
  • be permanently connected to consumer mains power (i.e. 240V hardwired)
  • be interconnected, if your home was newly built after the 1 May 2015.
  • be less than 10 years from the date of manufacture

Can I Use 10-Yr Battery Smoke Alarms In Western Australia?

YES you can! – W.A Building Regulations 2012 allow the use of 10 year non-replaceable battery powered smoke alarms in certain situations. This may include where mains power is not connected to the building, there is no hidden space to run the necessary wiring for mains powered alarms, and there is no appropriate alternative location – for example, where there is a solid concrete ceiling. It should be noted that formal approval must be obtained by the local council to use 10 year non-replaceable battery powered smoke alarms in these situations.

Smoke Alarm Laws In Western Australia Rental Properties

Landlords renting or hiring out their property are required to maintain the smoke alarms by law. This includes ensuring that the smoke alarm is;

  • in working order;
  • compliant to Australian Standard 3786;
  • connected (hard wired) to 240 volt mains power;
  • less than 10 years old from date of manufacture;
  • if the use of a battery powered smoke alarm has been approved by the local council, the alarm has a non-removeable 10-year life lithium battery.

ZEN Interconnected Smoke Alarms

Interconnected Smoke Detectors

And Australian Standard 3786:2014

Before buying a smoke alarm you should do your due diligence to ensure it is compliant to Australian Standard 3786:2014. The full name of the standard which encompasses smoke alarms in Australia is ‘Australian Standard 3786:2014 Smoke alarms using scattered light, transmitted light or ionization’ (incorporating amendment 1 and 2). This article will review Australian Standard 3786:2014 to assist your purchasing decision.

Standards are documents that set out specifications, procedures and guidelines to ensure products are safe, consistent, and reliable. Australian Standard 3786:2014 is referenced by QLD’s Building Fire Safety Regulations 2008 – when a standard is referenced by state or national legislation, compliance with it becomes mandatory. It is interesting to note that although there is a newer Australian Standard 3786:2023 – it is not yet referenced by legislation – therefore Australian Standard 3786:2014 must still be complied with in the eyes of the law.

Australian Standard 3786:2023

Australian Standard 3786:2014 is divided into several key components – the area of interest that will be reviewed today is section 4.17 – ‘general requirements’.

Section 4.17 of the Australian Standard states that; ‘The smoke alarm shall be so designed that a sphere of diameter larger than 1.3 ±0.05 mm cannot pass into the sensor chamber(s)’. This requirement is intended to restrict the access of foreign bodies such as insects into the sensitive parts of the smoke alarm (to prevent nuisance alarms). It is known that this requirement is not sufficient to prevent the access of all insects; however, it is considered that extreme restrictions on the size of the access holes may introduce the danger of clogging by dust, etc.

Interconnected Smoke Alarm – Mesh Screen

How does this requirement translate into the design and manufacture of your photoelectric smoke alarm? The image below shows the compliant internal component from our ZEN wireless interconnected photoelectric smoke alarm. The polymer mesh surrounding the sensitive photoelectric chamber within the alarm contains thousands of tiny holes, each perfectly engineered, no larger than 1.3mm in diameter. The tiny holes prevent insects from accessing the internal chamber whilst still allowing air (and smoke) to pass through.

Mesh screen surrounding the photoelectric smoke alarm internal sensor chamber

As per Australian Standard 3786:2014 – holes are no larger than 1.3mm diameter

In addition to this internal mesh screen around the perimeter of the photoelectric chamber, ZEN wireless photoelectric interconnected smoke detectors also have an external housing which forms part of the of the smoke alarm itself. The external housing prevents larger foreign bodies from entering the alarm itself. Foreign bodies (i.e., insects, small house geckos) are a common cause of false / nuisance alarms because they can enter the sensitive internal components and disrupt the photoelectric light beam.

We hope you have enjoyed this review of section 4.17 of Australian Standard 3786:2014, and how it translates to the design of your photoelectric smoke alarm. Whilst many smoke alarm retailers might profess to be aware of the standard, very few can claim to have read it from cover to cover or have a genuine understanding of what it means.

ZEN Interconnected Smoke Alarms

Nothing is more annoying than a smoke alarm going off for no reason (especially at 3am in the morning!). But why is your smoke alarm beeping without smoke being physically present? There could be several reasons for false alarms. The good news is that you don’t have to go on living this way – our ZEN wireless photoelectric interconnected smoke detectors provide reliable and trustworthy protection for you and your family.

The basic operating principal of a photoelectric smoke alarm is that it activates when the light beam inside the smoke alarm chamber is broken or disrupted – typically by tiny smoke particles. However these foreign particles can also come from sources other than real smoke – below are some of the most common examples and how to rectify them.

High Humidity Affecting The Smoke Alarms

High humidity can occur naturally as the air carries dense moisture particles that your smoke alarm confuses for smoke particles. Although brands can differ, smoke alarms should be designed to work up to 93% relative humidity (RH) as per the Australian Standard 3786:2014 – however anything over 85% RH range and air could potentially become dense enough to scatter the light beam of a photelectric sensor. Extreme tropical weather conditions in the Northern Territory and far north Queensland can sometimes produce these high humidity conditions.

High humidity can also be artificially created by steam from a bathroom shower or the clothes dryer running inside a laundry room. If your smoke alarm is positioned outside a bathroom entrance or inside the laundry, consider moving it further away or out of that room altogether so that escaping shower steam and humid air doesn’t trigger a false alarm and start your smoke alarm beeping and going off for no reason.

Dust Particles Inside Your Interconnected Smoke Alarms

A build-up of dust in the air can also affect your smoke alarm. If dust particles enter the internal chamber they will interfere with the photoelectric light beam and trigger nuisance alarms. We recommend cleaning your smoke alarms regularly by gently vacuuming around them with a soft brush attachment from your vacuum cleaner. Cleaning interconnected smoke detectors in this way may remove any cobwebs which could also prevent pests from entering the fire alarm. Be aware of any activities in the home which may create excess dust – for example renovations or shaking out old dusty blankets or doonas in a room which has a smoke detector installed.

Insects Inside Your Interconnected Smoke Detectors

Section 4.17 of Australian Standard 3786:2014 requires smoke alarms to have protection against foreign bodies, so that a sphere of diameter larger than 1.3mm cannot pass into the sensor chamber – this protection is provided by way of an internal mesh screen. Despite this requirement it is still possible that very tiny insects (smaller than 1.3mm) could enter the smoke alarm and by doing so interfere with the photoelectric sensor. One tip to reduce this likelihood is to wipe the ceiling perimeter around your smoke alarm with surface insect spray (be sure not to allow the insect spray itself to enter the alarm as this could affect its sensors which, you guessed it, could create false alarming).

Cooking Vapour Affecting Your Smoke Alarm Sensors

It is true that whilst many house fires start in the kitchen, installing an alarm in the kitchen can induce frequent nuisance alarms. Irrespective of what smoke alarm brand you have, if it is installed too close to the kitchen stovetop or oven it will activate and start beeping when smoke particles are emitted from the food cooking process (after all, the smoke alarm is doing what it is designed to do). When cooking, always be sure to switch on the rangehood or oven exhaust fan to draw smoky air particles away from your smoke alarm. If the problem continues, try repositioning the fire alarm further away from the cooking appliance.

Summary

Beeping smoke alarms that are going off for no apparent reason can be both frustrating and stressful. Worse, an ongoing beeping smoke alarm may generate a ‘boy who cried wolf’ effect, reducing home occupants reaction to a real life fire event.

Fortunately, our ZEN wireless interconnected smoke detectors undergo strict quality control measures at an ISO 9001 quality accredited facility, are manufactured in adherence to Australian Standard 3786:2014, and are independently tested which means the likelihood for nuisance alarms is greatly reduced. Using the tips outlined above and below, your ZEN interconnected smoke detectors will provide many years of stress-free and reliable fire protection for you and your loved ones.

ZEN Interconnected Smoke Alarms

As the winter freeze gradually gives way to the warmth of a Queensland spring, we find ourselves emerging from the hibernation of the chilly months. Spring cleaning, gardening and home maintenance tasks become top priorities, and one key activity that should not be overlooked is the checking of your interconnected smoke detectors. Whilst this may not seem like the most exciting of springtime jobs, it is definetely one of the most important. The primary purpose of interconnected smoke alarms is to protect you and your loved ones in the event of a fire. By checking them at the onset of the spring, you can be sure that they are in good working condition and ready to alert you in case of an emergency.

Here’s how you should make checking your interconnected smoke detectors a regular springtime ritual.

Interconnected Smoke Detectors Spring Cleaning

Did you know that the changing seasonal weather can have an impact on your photoelectric interconnected smoke detectors? During winter, dust and debris can accumulate inside them, reducing their efficiency and increasing the possibility for nuisance alarms. Springtime also sees the release of botanical plant pollens and microscopic spores which if left unchecked can affect the internal sensors of your alarms. Whilst you’re already in spring cleaning mode, why not take a few extra minutes to ensure your smoke alarms are fully clean and operational. Gently vacuum around the exterior shell of your smoke detectors with the soft brush attachment from a vacuum cleaner to remove any cobwebs, dust build-up etc. In addition to this spring clean, we recommend to clean your ZEN smoke alarms 6 monthly.

Check The Smoke Alarm Batteries

Smoke alarms often rely on batteries for power, and these batteries can weaken or die over time. Fortunately most modern interconnected smoke detectors are now equipped with 10-year long life lithium batteries which are sealed inside the smoke alarm itself (after 10 years the entire smoke alarm is simply swapped out for a new one). However, if you still have an older style smoke alarm which uses 9V replaceable batteries then spring is a great time to either replace the old batteries with fresh ones, or our recommendation is to upgrade to new alarms with inbuilt 10-year long life batteries. So, go ahead, replace those dusty old 9V replaceable battery smoke alarms in springtime with the newest ZEN photoelectric interconnected smoke detectors equipped with 10-year long life batteries, and ensure your alarms are always ready to do their job.

Test Your Interconnected Smoke Alarms In Spring

Testing your interconnected smoke detectors is a relatively quick and straightforward task. You don’t need any special tools or expertise. Aside from the start of Spring, we recommend to test your ZEN smoke alarms monthly. It’s a small effort for a significant safety boost. In QLD smoke alarms must be interconnected (so if one smoke alarm activates, they all do). ZEN interconnected smoke detectors have a ‘test’ button that you can press to ensure they are working correctly. When testing your fire alarms be sure to check that all the smoke alarms are interconnected and activate together, usually within about 10 seconds of the test button being pressed on the first smoke alarm. If not, it’s time for some troubleshooting or possibly a replacement. To test your ZEN smoke alarms simply press the centre surface of the alarm itself, or press the test button once on the optional remote control device. Test mode will conclude after approx. 10 seconds and all alarms will automatically silence.

What Is The Smoke Alarm Expiry Date?

Smoke alarms don’t last forever and should be replaced 10 years from the date of manufacture. According to Australian Standard 3786:2014, the smoke alarm date of manufacture should be printed on the rear of the smoke alarm – go on, have a look. If they’re older than 10 years then they should be replaced with newer models. Why? Photoelectric sensors and other internal components can degrade over time, leading to a less effective smoke alarm.

Interconnected Smoke Alarm Location

Whilst you’re at it, double-check the placement of your interconnected smoke detectors. Are they strategically positioned throughout your home as per Queensland smoke alarm laws? In Queensland there should be one smoke detector inside each bedroom, the interconnecting hallway outside the bedrooms, and at least one on each level of your home. If there is no interconnecting hallway outside the bedrooms then a smoke alarm must be installed outside the bedroom and other parts of the storey. Proper placement can make all the difference in early detection.

Teach Your Family About Interconnected Smoke Detectors

Checking your interconnected smoke detectors in the spring also presents an opportunity to educate your family about fire safety (especially children). Show them how to test the alarms and what to do and who to call in case they hear one go off. This knowledge can be invaluable in an emergency situation.

If you do not have one already, prepare a home fire escape plan and rehearse it at the start of Spring with all your family members.
