“These smoke alarms were easy to install & much cheaper than the ones I needed an electrician to install but also up to the legal regulations unlike the cheaper alarms – Sam Windger   5☆☆☆☆☆

Our Most Popular Interconnected Photoelectric Smoke Alarms


The legislation changes as of January 1st, 2017 will require some residential properties (in some states) to have a photoelectric smoke alarm in each bedroom, in hallways that connect bedrooms and at least one on every storey of a multi level property, in the most likely route to exit. To be compliant, a 3 bedroom, 2 storey house will likely need 5 smoke alarms, possibly more depending on floor layout.

Not all smoke alarms are created equal.

Smoke alarms are required by law and new legislation as of January 2017 in some states require that all residential homes have photoelectric smoke alarms installed when a smoke alarm is replaced or installed. The legislation will require1 a smoke alarm to be installed in every bedroom & on each storey AND

  • Must be photoelectric alarms (Australian Standard AS 3786-2014)
  • Not also contain an ionisation sensor
  • Interconnected to every other smoke alarm
  • Powered by the mains electricity supply or a non-removable battery with a 10-year battery life

What this means is that a lot of the alarms that are currently being sold are no longer compliant and may not be as safe. Don’t put your family’s lives or your tenants lives at risk! Furthermore, if you’re not compliant you may not be insured.

Buy our fully compliant smoke alarms online now and be protected.

* Note: An alarm currently connected to the mains power supply must be replaced by another alarm also connected to the mains power supply and a qualified electrician is necessary for this.
1 Required in Queensland by Jan 1 2022 for residential rental properties and by Jan 1 2027 for all residential properties.

Why These Laws Have Been Implemented

In September 2016, a fire spread rapidly throughout a home in Brisbane, which was fully engulfed by the time fire brigades arrived. It is understood the presence of two cars and four 45 litre gas bottles fuelled the flames.

The tight-knit community came to terms with the loss of three adults, four teenagers and four children, the youngest a three-year-old girl.

After this a coroner in Qld recommended that photoelectric alarms be made compulsory, following Australia’s deadliest house fire.  Qld State Government has now made this law. Other states are yet to decide.

Smoke Alarms Australia

Finding a photoelectric smoke alarm that’s powered by a 10 year non-removable battery which can be interconnected wirelessly can be tough. We’ve done the hard work for you and attempted to source the best and legally compliant smoke alarms. We can deliver our smoke alarms to every city in Australia.

  • Wireless Interconnected Smoke Alarms

    Interconnected smoke alarms mean that if one smoke alarm goes off, then all other alarms will also go off.  Wherever you are in the property, you are sure to be alerted. This is particularly important whilst you are asleep and a fire starts on another floor or at the farthest part of the property since you may not hear the alarm in the immediate vicinity of the fire that sounded the alert.

    The photoelectric smoke alarms sold on this site can be interconnected wirelessly and are therefore ideal for installation into an existing home. There is no need for an electrician, saving you costly installation and interconnection fees for wiring cables from one to another, which might be particularly expensive in a multi-storey residence interconnecting downstairs to upstairs.

    Smoke Alarm Placement

    Smoke alarms ideally should be on the ceiling and not be within:

    • 30cm of a corner of a wall and the ceiling or at the top of angled ceilings.
    • 30cm of a light
    • 40cm of an air-conditioning unit/vent or a ceiling fan.

    There are special requirements for stairways, sloping ceilings, and ceilings with exposed beams.

    Avoid installing smoke alarms:

    • in space with dead air. This is where the air can be trapped and will stop smoke from getting to the alarm such as between exposed beams or joists.
    • near fans, air-conditioners, windows or doors since too much air movement may stop smoke from reaching the alarm.
    • in or near kitchens and bathrooms where smoke from cooking or steam can set off accidental alarms.
    • in insect infested areas since some alarms can be accidentally triggered by insects flying into them.

  • Q. Do I need an electrician?
    A. You can install them yourself if they are alarms powered by a battery and are not hard-wire interconnected. Screw fixings, with an easy twist-on base design, are supplied with these alarms. If an electrician is required, we’ll state this in the information section.

    Q. Can I replace an alarm powered by the mains supply with a battery powered one?
    A. Sorry, an alarm powered by the mains supply must be replaced by an alarm powered by the mains supply and unfortunately you are required to have a licenced electrician do this for you.

    Q. How many alarms will I need?
    A. That depends on the floor layout of your home and what state your property is located in. Your local Emergency Services may be able to advise further.

    Q. Is it possible that an alarm triggered in my neighbours home will set of my alarms?
    A. LOL No. Since the interconnection is wireless and uses a radio frequency the alarms must be paired to each other and all alarms in the property must be paired with a ‘master’ alarm.

    Q. How do I know when my current smoke alarms expire and need replacing?
    A. The smoke alarms should be replaced 10 years from the manufacture date. To find out how old your smoke alarm is and its expiration date, simply look on the back of the alarm where the date of manufacture is marked.

    Q. How can I tell what type of smoke alarm I have currently installed?
    A. Each smoke detectors label should be clearly state if it is an ionisation or photoelectric smoke alarm, possibly just with the letters ‘P’ or ‘I’. However, if it is not clearly stated you will see a bright yellow ‘radiation’ symbol inside or on the back of an ionisation alarm.

    Q. Are your alarms compliant with AS3786:2014?
    A. Definitely. We have gone to great lengths to ensure ours are up to the latest standard. Be warned, though, that many alarms still on the market are only compliant to the older AS3786:1993 standard.
