Everything you need to know about smoke alarms for residential buildings (Class 1a)

What type of smoke alarm do I install?

The smoke alarm must:

  1. comply with AS 3786:2014 standards
  2. contain a photoelectric sensor and not an ionising sensor (Queensland and Northern Territory only)
  3. be hard-wired to the mains electricity power supply (with battery backup) for homes built after (SA 1995) (TAS, WA, NSW, VIC & QLD 1997) (NT 1998)
  4. be interconnected to every other smoke alarm installed in the dwelling via hard wire or wireless connectivity for:
    1. homes built after 1st May 2014
    2. all rental properties in Queensland
    3. all owner occupied homes in Queensland starting from January 1st 2027
  5. at minimum, have a 10-year non-replaceable battery for:
    1. homes built prior to July 1997 in Queensland
    2. homes built prior to July 1998 in Northern Territory
    3. homes built prior to October 2009 in Western Australia (only where a mains smoke alarm is not able to be installed)
    4. homes built prior to 1995 and later purchased or leased/rented in South Australia
    5. homes built prior to August 1997 and later rented/leased in Victoria
    6. homes built prior to July 1997 and rented/leased in Tasmania
    7. use as additional smoke alarms above the state/territory requirement

What about the maintenance of a smoke alarm?

The smoke alarm:

  1. must be replaced after 10 years from date of manufacture
  2. must be replaced after a fire
  3. needs to be tested every month
  4. needs to be cleaned every 3 to 6 months - Use a vacuum cleaner with a soft brush to clean dust and cobwebs. Then spray insect repellent on a cloth and gently wipe around the smoke alarm to keep insects out. Do not spray inside the smoke alarm. Also, check the unit for a build-up of oils from cooking, or from insects and their by-products, as these may be blocking the sensor and can cause a false alarm.
  5. if the smoke alarm contains a replaceable battery backup, the battery must be replaced every 12 months.
  6. if the smoke alarm is 'chirping' or 'beeping', there are typically two main reasons:
    1. Low battery. If the alarm starts beeping once every 40 seconds, the backup battery needs replacing.
    2. False alarm. If your Clipsal smoke alarms are going off when there is no smoke present, firstly identify the unit which has been triggered. You can do this by looking for the smoke alarm with the flashing Red LED, while the alarms are still sounding, or by looking for one flash ever 2 seconds for up to 72 hrs. Once identified, follow the cleaning instructions above. If the problem chirp or beep remains, the smoke alarm may need replacing.
