Ever wondered how to physically attach a smoke alarm onto your ceiling? Click here to watch this short video – it demonstrates how easy it is! A key benefit of our wireless lithium battery powered smoke alarms is that there is no hardwiring involved – this means they can be legally installed by home owners without needing an electrician.

Checklist for how to attach a smoke detector onto the ceiling

Checklist of what’s needed:

  • Pencil
  • Hammer
  • Drill with 5mm drill bit
  • Screws and anchor plugs x 2 (included with our smoke alarms)
  • Smoke alarm and its mounting bracket

Twist the mounting bracket to remove it from the smoke detector

STEP 1: Twist the mounting bracket to remove it from the rear of the smoke alarm.

Use a pencil to mark location of the smoke detector's mounting bracket slots on the ceiling

STEP 2: Locate the mounting bracket in your chosen position on the ceiling. Use a pencil to mark the location of the two mounting bracket slots on the ceiling. Refer to general guidance at the end of this article about where best to locate your smoke detector so that it is compliant with legislation.

Use a 5mm drill bit to drill two pilot holes into the ceiling for the smoke detector bracket

STEP 3: Use a 5mm drill bit to drill a pilot hole at each location marked on the ceiling. Now insert the anchor plugs. If necessary give the anchor plugs a tap with a small hammer so they are in nice and snug inside the drilled holes. Now use the two screws to attach the mounting bracket to the chosen position.

Important – don’t over-tighten the screws as this may slightly distort the shape of the plastic mounting bracket (and prevent the smoke alarm from being able to ‘lock’ into it).

Turn clockwise to lock the smoke detector onto the mounting bracket on the ceiling

STEP 4: Attach the smoke alarm to the mounting bracket and turn clockwise to lock it into place. By attaching the smoke alarm to the mounting bracket, the on/off switch is engaged and the alarm will be powered on (if it has not been switched on manually already).

Press the test button on the smoke detector to ensure it is interconnected and working properly

STEP 5: Press the test button to ensure you smoke alarm is working properly. If you have more than one interconnected smoke detector, then the others in the same group should also activate within approximately 10-15 seconds (this is normal). Allow all the smoke alarms to finish their full test cycle without pressing the hush button – they will all stop automatically after approximately 10-15 seconds.

Where should I install interconnected smoke detectors?

As general guidance, smoke detectors in QLD should be placed inside every bedroom, interconnecting hallway outside the bedrooms, and on every level of a multi-story dwelling (refer to QLD Fire and Emergency Services for further info). Additionally, smoke detectors should not be installed within 30cm from the edge of a wall, within 30cm from a light fixture, 40cm from an air con vent and also within 40cm from a ceiling fan blade. It is preferable to install smoke detectors on the ceiling, as opposed to the wall.

Safety note – Prior to undertaking any home maintenance, it is a good idea to have suitable personal protective equipment (PPE) for the task at hand i.e. safety glasses when operating a drill. If using a ladder to reach the ceiling it may be helpful to have someone hold the ladder steady whilst you are standing on it. 240v smoke alarms which are hardwired to mains power (i.e. not the ones in this article) should always be installed by a qualified electrician. If replacing a 240v hardwired smoke alarm in Queensland it must be replaced with a 240v hardwired smoke alarm.
