Answer

The listed operating temperature range of this product is 40°F to 100°F. Due to potential drastic temperature changes smoke alarms may not operate properly and could be damaged when used in hot, cold or dirty locations. Heat alarms are the preferred product for installation in an unfinished attic space.

Answer

Gentex still manufactures the 9123F Series. You can replace your 9123F with a new 9123F or with an S1209F. If you use the S1209F, you will have to change and re-wire the wire harness that is shipped with the S1209F.

No, a low battery chirp will not cause the alarm relays to trigger. The relays will only function when the device goes into alarm mode.

I bought these to replace all of my old wired smoke detectors. They work great, and take care of both the CO and smoke requirement. I bought this particular unit because I have to tie in all of the smokes/CO to a central alarm, and I can put a Form C relay in this unit to accomplish that goal. Plus the units are US made.
