BCA Smoke Alarm changes

Earlier this year, The Australian Building Codes Board released the National Construction Code 2014, which came into effect as of May 1st, 2014. There are 2 changes that affect us in the electrical industry.

Interconnection of smoke alarms:
Previously, smoke alarms were only required to be connected to consumer mains power where available, they must now also be interconnected when installed in Class 1 buildings. This new requirement has been introduced to increase the likelihood that sleeping occupants will be made aware of smoke in other areas of the home, as all alarms will sound when one is triggered.

Exit signs:
Photoluminescent (glow in the dark) exit signs can now be used as an alternative to exit signs illuminated by a power source. However, the NCC also stipulates that there must be a dedicated, uninterrupted light source of 100lux to the face of the sign.
