Proposed Changes to BCA 2014

The Building Code of Australia 2014 proposes changes be introduced in regards to the interconnection of smoke alarms.

From 1 May 2014, smoke alarms will required to be interconnected  in Class 1 buildings.  Currently the Building Code of Australia has no requirements for smoke alarms in Class 1a and 1b buildings connected to mains power to be interconnected.

The reason for this change is to increase the awareness of smoke in another part of a dwelling where two or more smoke alarms are installed.  This is particularly useful in two storey houses, or those where bedrooms are located in separate areas.

A list of amendments to the Building Code of Australia 2014 has been published by the ABCB and is available at:
