Frequently Asked Questions

The number of interconnected smoke alarms required is relative to the floor layout and what state the dwelling is located in. QLD law states that a smoke alarm must be installed on each storey;

  • in each bedroom
  • in hallways that connect bedrooms and the rest of the dwelling
  • if there is no hallway, between the bedroom and other parts of the storey
  • if there are no bedrooms on a storey, at least one smoke alarm must be installed in the most likely path of travel to exit the dwelling.

The example floorplan below was developed by the Queensland Fire Department and depicts required interconnected smoke alarm locations within a dwelling – use this as a guide for determining your own requirements.

Wireless Interconnected Photoelectric Smoke Alarm Placement Recommendations

Where practicable smoke alarms must be placed on the ceiling. Smoke alarms must not be placed:

  • Within 30cm of a corner of a ceiling and a wall
  • Within 30cm of a light fitting
  • Within 40cm of an air-conditioning vent or the blades of a ceiling fan

There are special requirements for stairways, sloping ceilings, and ceilings with exposed beams. Specific requirements are further explained in the QLD Building Fire Safety Regulation 2008.


ZEN wireless interconnected smoke alarms are powered by a non-removeable 10-year battery (not hardwired to 240V mains power). Wireless 10-year battery powered smoke alarms can be easily DIY installed by anyone and do not require an electrician.

Please note however if you purchase one of our Emerald 240V hardwired smoke alarms then yes it will need to be installed by a licensed electrician.

Please refer to your state legislation. QLD legislation states that if an existing 240V hardwired alarm is to be replaced, then it must be replaced with another 240V hardwired photoelectric smoke alarm.

The National Construction Code (NCC) also states that any new dwellings being constructed or substantially renovated must have 240V hardwired photoelectric smoke alarms installed.

A compliance certificate is not needed. The seller of a Queensland property does not need to provide a certificate to confirm ZEN Interconnected Smoke Alarms are installed and are compliant. The seller only needs to tick yes or no to the relevant box in the Contract of Sale and Form 24.

Please refer to the Real Estate Institute of Queensland’s (REIQ) fact sheet below.

Our helpful blog post also contains more information about smoke alarm compliance when selling your property in QLD.

Selling in QLD and the smoke alarm compliance certificate

Yes! ZEN Interconnected Smoke Alarms can be interconnected together in any combination you wish, up to 30 interconnected together, making a larger bundle pack purchase for multiple properties the best value option. Additional alarms and remotes can be purchased individually. It’s fully flexible and up to you to decide.

Some insurance providers can decline to quote your property if you don’t fulfil their underwriting criteria when it comes to fire protection. It is always recommended to install photoelectric interconnected smoke alarms and check with your insurance provider or insurance broker to make sure you meet the necessary requirements.

No. The interconnection is wireless and uses a radio frequency so that the alarms must be uniquely paired to one another. All interconnected smoke alarms in one property are paired with a ‘master’ alarm, which is distinct from a ‘master’ alarm on any adjoining property.

Both brands comply to Australian Standard 3786:2014 and both brands are very good!

Emerald smoke alarms also manufacture a 240V hardwired (mains powered) smoke alarm – this is useful for some people who require a combination of both types in their property (QLD legislation says any existing hardwired smoke alarms must be replaced with hardwired).

Emerald smoke alarms are not compatible with ZEN Smoke Alarms, and vice versa (i.e. different brands cannot be interconnected together).
