To me, this one is cut and dry in the province of Ontario.

In the 1994 building code, it states that smoke alarms must be installed with permanant connections to an electrical circuit having no disconnect switch between breaker/fuse and the device. [3.2.4.22(4)]

So, when you've gotta pull wires to bring your building under retro up to code, use 14/3 not 14/2.

(1990 and 1986 codes say roughly the same thing. Both also include a statement that within a dwelling unit, detectors shall be wired so that activation of one causes all others to activate [this statement is not present in the 1994 appendix of the current fire code])

While the building code does indeed say such, we are fire officials, and therefore must use the Ontario Fire Code.
In each section of the fire code if you read it through, battery operated smoke alarms are "Deemed to be in compliance".
See:
Smoke alarms

9.8.4.2. (1) Smoke alarms shall be installed in each dwelling unit in accordance with Sentences 3.2.4.21.(1) to (4) of the 1994 Building Code.

(2) Battery-operated smoke alarms are deemed to be in compliance with Sentence 3.2.4.21.(4) of the 1994 Building Code.

Smoke alarms

9.5.4.5. (1) Smoke alarms shall be installed in each dwelling unit and in each sleeping room not within a dwelling unit in accordance with Article 3.2.4.21. of the 1990 Building Code.

(2) Battery-operated smoke alarms are deemed to be in compliance with Sentence 3.2.4.21.(4) of the 1990 Building Code.

2.13.2.1. (1) Smoke alarms conforming to CAN/ULC-S531, “Standard for Smoke Alarms”, shall be installed in accordance with this Article.

(4) Smoke alarms shall be installed by permanent connections to an electrical circuit and shall have no disconnect switch between the overcurrent device and the smoke alarm.

(5) Battery-operated smoke alarms are deemed to be in compliance with Sentence (3).

(6) Existing smoke alarms meeting the requirements of ULC-S531-1978, “Standard for Smoke Alarms”, are deemed to be in compliance with Sentence (1).

There are some instances in the fire code that call specifically for hard wired interconnected smoke alarms, and these are generally taking into account other life safety features that are existing or easibly attainable. In these cases, it would be up to the Chief Fire Official to accept the particular installation as an Alternative measure.

I personnaly think that most Chief Fire Officials would take into account all factors including cost and disruption to building owners and tenants when making the decision.

Thanks. Not great with the retro stuff. Currently working private sector fire protection, so I don't get a whole lot of exposure to it. Generally we hardwire everything anyways - if someone wants wireless, they are free to explore that option on their own, or with another company.
