Joe,
Unfortunately, the wireless smoke alarms are not recognized by the OBC or OFC.
We have come across these type of units.
We have ordered for the alarms to be hardwired & interconnected as per the code ref: 9.5.4.4. as referenced by 9.7.5.1.(7)
Justifying decision:
Did you mean 9.1.2.2.(3) or 9.1.1.3. ??
I guess the question here would be, can they prove the buildings seen as a care occupancy as is was read in the building code in 1998?
I would not recommend 9.1.1.3. as an option.
I hope this helps.
Martyn.
