How to install our smoke detectors onto your ceiling – DIY is so easy and save big $$$

Ever wondered how to physically attach a smoke a detector onto your ceiling? Click here to watch this short video – it demonstrates how simple it really is! A major advantage of wireless lithium battery powered smoke alarms is that there is no hardwiring involved – this means they can be legally installed by property owners without requiring an electrician.

Checklist of items needed 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 mounting bracket and remove from rear of the smoke alarm

STEP 1: Twist the mounting bracket to remove it from the back of the smoke detector.

use a pencil to mark out the smoke detector 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 as per above.

Important – 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 mounting 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 and use the two screws to attach the mounting bracket to the chosen position.

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).

Firmly twist the smoke detector in a clockwise direction to lock it into place on the mounting bracket on the ceiling

STEP 4: Attach the smoke alarm to the mounting bracket and firmly 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 become powered on (if it has not been switched on manually already).

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 Queensland should be placed inside every bedroom, interconnecting hallway outside the bedrooms, and on every level of a multi-story dwelling. 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 conditioner vent and also not within 40cm from a ceiling fan blade. It is preferable to install smoke detectors on the ceiling, as opposed to the wall (refer to the Queensland Fire and Emergency Services for more information).

Safety note – Prior to undertaking any home maintenance, it is a good idea to have suitable personal protective equipment (PPE) available, for example safety glasses when operating a drill. If using a ladder to reach the ceiling it also helps to have someone hold the ladder steady whilst you are standing on it. 240v smoke detectors which are hardwired to mains power (i.e. not the lithium battery ones as described in this article) should always be installed by a qualified electrician. Don’t forget – if replacing a 240v hardwired smoke detector in Queensland it must be replaced with a 240v hardwired smoke detector.
