Interconnected Smoke Alarms – 9.5.4.4.

[Joseph Gardiner]

Hello,

We have a series of converted single family dwellings in North Bay that are one storey in building height with a basement level containing 4 or less occupants and these buildings are subjected to 9.7 retrofit.

9.7.5.1. (7) exempts the sprinkler requirement if the building is equipped with hardwired interconnected smoke alarms complying with 9.5.4.4. The requirement for 9.5.4.4. (1)(c) indicates the smoke alarm system has to be connected to an electrical circuit. These buildings currently possess battery operated (only) wireless interconnected smoke alarms.

I would like your thoughts on whether to approve the systems or have the buildings install a system that is electrically connected.

I would want to qualify my decision if our office were to approve the battery operated wireless system under 9.1.2.3.

I am wondering if someone has dealt with a situation like this or has extensive knowledge about these battery operated wireless systems.

Thank you,
