it’s usually fine but as an alternative you can use a heat detector. They are no where near as fast to respond though.

edit: and heat detectors are generally useless when it comes to detecting smoldering fires and the like for obvious reasons.

As a firefighter, I can confidently say that you’ll be ok. BUT, you will want to change the battery/batteries more frequently, due to the cooler temps. We always say to change batteries in your detectors twice a year (time change days) “Change your clock, change your batteries”. And when you do change the batteries in that detector, make sure you use some compressed air and do a quick cleaning of any potential dust build-up inside the detector, since it will be in a high(er) dust environment.

I was at Costco yesterday and saw they have a 2 pack of smoke and CO combo detectors for $60. Pretty good deal.
