I had been away from home for a short time. When arriving home I could hear the CO alarm, after checking the area I determined that the unit was at fault. I ordered a new CO5120BN and an additional as a spare. The replacement arrived in less than a week allowing me to solve he problem. It was the exact unit I needed so no change of wiring was required. Thanks First Alert for the excellent service.

Replaced Smoke/CO with CO only due to builders error, within 5 of stove. CO needed there for BR door. Would have been easier if base plate had been the same for all hardwired models.
