Smoke detectors are on the ceiling and are powered by a 9 volt internal battery only. If they chirp, replace internal battery.
Some CO detectors will detect the presence of LP as well as CO which is probably why they are installed close to the floor, LP being heavier then air. Their real purpose in our Entegras is to warn of the presence of generator exhaust, either yours or your neighbors even though CO is slightly lighter then air.
CO/LP detectors are powered off of your vehicle battery's. No internal backup 9 volt battery. If the vehicle batterys run down over night and gets below something like 11.5 volts (not sure the real value), they will begin to chirp. Run genny to recharge vehicle battery's and the CO/LP detector will stop chirping.
Be safe and don't forget to test these devices periodically.

Ron, good post. I just learned from experience, not that I wanted to The CO detector goes off at 10.5v for low voltage warning. Mine did not chirp, it went off full blast. When my batteries went dead, it went off at midnight. Without the Command 30, 4.0 update, the voltage fell to fast to start the generator. Not a fun learning experience.

Emerson, my first CO detector did the same thing as yours. The replaced one has been fine. Brings up a good point.....can you turn off the circuit breaker on a 17? I pulled the fuse on mine until the new one arrived.
