Can I use a hardwire smoke/CO detector on batteries alone?
Thomas asked:
The Kidde combo Smoke/CO detector that is interconnectable I want only comes as a hardwired detector with battery backup. Is it possible to just use it as a battery operated unit without connecting it to my house wiring? I assume the answer is yes since the battery is backup power.

Yes you can but you will need to use a good 9volt battery preferably a lithium for the unit. Check for the proper operation every three months. when the battery gets too weak then replace, regular batteries usually every 9-12 months. Lithium every three years. Clint

The problem is (as I found out with mine) is that without the power from the house the detector gives a short beep every few minutes to indicate the power outage or circuit being off.
I found this out when I shut off the wrong breaker in my house.
That would drive me nuts if I had to listen to that more than 10 minutes. mactruck

Yes you can use it without power. But you will not like the beep. They typically beep to let you know you don’t have 120 volt power or it will also beep to let you know the 9 volt dc battery is dead. Brian G
