Smoke Alarms

The Building Code of Australia (BCA) contains Specification E2.2a Smoke Detection and Alarm Systems (smoke alarms). Part E2 Smoke Hazard Management and the Specification dictate which buildings require smoke alarms, which ultimately became an essential safety measure when nominated by the building surveyor/ building certifier.

The BCA requires smoke alarms system to be installed in a building to provide early warning of a fire to enable quick evacuation. The smoke alarms system must operate to a level that detects the presence and location of a fire and alert the fire brigade.
