Installing Smoke Alarms

 

Sample Smoke Alarm house planInstalling smoke alarms

When installing a mains powered smoke alarms, always use a licensed electrician.

It is recommended that smoke alarms be located in all sleeping areas and in all paths of travel between sleeping areas and exits to the open air.

This includes sleeping areas in separate parts of the house and where sleep-outs or similar areas are not connected by a passageway to the main part of the dwelling.

It is particularly important to install a smoke alarm inside bedrooms where:

  • People sleep with their bedroom doors closed, particularly if heaters or electrical appliances are used in those rooms
  • People smoke in their bedrooms
  • Noisy equipment such as air-conditioners, televisions or stereos may mask the sound of a remote smoke alarms

Where not to install a smoke alarm

  • Wherever possible, smoke alarms should not be installed near kitchens, laundries and bathrooms

Multi-level houses

In addition to the above provisions, it is recommended smoke alarms be located in the path of travel between each level. See diagram below.

  • The distance from the apex of a cathedral ceiling to the smoke alarm should be between 500mm and 1500mm
