We bought a house in March, 2017, with hard wired smoke detectors. One is constantly beeping and the button only works for 30 minutes or so. I changed the battery. What do I need to do to stop the beeping? There are 2 in the house and the other one is not beeping. What do I need to do?
Asked by: Sonja
Yes mine was doing the same ! I changed the batteries and that didn't work so when I looked further into it they were the same age as the house 2003. So they needed replaced ,but I don't understand why just one went off and not the other . Ours were all tied together. I hope this is helpful.

Is it mandatory to install a battery in this model? Will it still function,and not beep constantly without a battery installed??
Asked by: GJ
Perhaps not “mandatory” but places you/family at risk if hard wired alarms lose power and do not alarm. For this reason, the battery backup is indicated. Chirping alarm may need troubleshooting or approved battery.

I have old alarms that are bad will these hook up to same wiring??
Asked by: buzz
Not if you have Kidde 1275 alarms. I was led to believe that the connectors for all Kidde alarms were backwards compatible. Not true. My 1275 connectors do not fit this alarm. I would have to rewire all the connectors in my house to make these work.

The ceiling bracket has a variety of holes that will fit any junction box that the builder put in your home. If you're not afraid of electricity, you can install them while the wires are hot so you can test each one after you install it. They come with Kidde brand batteries which are not the greatest but should last a couple of years before needing replacement,

I took my old detectors down to paint and realized they had yellowed. While they were in my hand I tested them. I have a total of 5, out of those 2 didn't work. They are 18 years old and the recommended life span is 10. I will test regularly from now on, a small investment for round the clock safety.
