One more smoke question

I am wiring my new construction for Smokes today. I don't mine a few feet of extra labor and wire. So, should I put a smoke in the attached garage. Seems logical to me since that's where there is great fire potential what with vehicles, tools petroleum, etc...
However if installing at this location would violate NEC then of course I won't do it. Thanks
Jim

Smoke detectors are not covered in the NEC other then the wiring methods used to power them, even then it is only covered as a general wiring method. Smokes (and CO detectors) would be covered in building codes.

I have never installed a smoke in a garage. I suspect the exhaust and moisture from cars would cause too many false alarms.

Ok thanks,
Just in case there is anybody with a smoke installed in their attached garage I would be interested to hear how that has worked for you. Thanks

The NEC does not dictate SD locations, you could check with the Fire prevention officer at your FD and see what they recommend, I don't recall ever seeing a smoke detector in a garage, but maybe a heat detector.

I would install a heat detector. The garage is going to be outside the operating temperature range of a smoke alarm.

I agree with pcboss. Only a heat detector is used in the garage.

Add a heat detector.

Not sure where in TN you live but Knox County has the requirements online.

Right - Rate of rise and heat detector (all in one).

To all who responded-thank you for the great information. I would never have thought of a heat detector but that is good for me. Jim
