Battery Backup Guide

Jimmy T asked:


The smoke detectors do not have a test button and I disabled the security system (unplugged unit and battery backup) cause I don’t use it and the battery backup was failing, causing the security panels to chirp. Now it dawned on me that the smoke detectors might have been disabled.

I have 2 smoke detectors in my home that won’t stop chirping. It started last night when the power to my home cut on and off several times. They are hard wired into the ceiling (have a circuit breaker switch) as well as 9 volt battery backup power. I have turned the circuit breaker switch off and removed the battery and they still keep chirping. I finally had to take them off the ceiling completely. Any idea why this would be happening? I tested the batteries and they are charged. The batteries as well as the smoke detectors are only about a year old.

I bought a house about a year and a half ago and it came with electrical smoke detectors (with NO battery backup), they only chirp when it gets below used to be 63 degrees, now they are chirping at anything under 68 and occasionally at 68 degrees, what does this mean, and how do I stop it from chirping???

Jeff- <3 God <3 people asked:


So one of our smoke detectors keeps chirping. It is hard wired into the electrical system of our house & doesn’t have a battery backup (that I can see). How do I stop it from chirping short of hitting it with a bat in the middle of the night?
Or is it time for a new one?
Edit 1-
It did it for a few weeks, then stopped.
Now it has been doing it for the last two nights again.
Edit 2-
I have several upstairs (4) & this is the only one doing it.

Chloe asked:


Our condo unit has 6 smoke detectors throughout. When smoke in one condo (from cooking or fireplace) sets off smoke detector in one unit, all other units go off. The detectors are connected to the ceiling and have a battery. When the battery is low, it emits a beeping sound. When I have replaced the battery, there are wires that come from the ceiling that are plugged alongside the battery. That leads me to believe the smoke detector was hardwired with a battery backup. Now condo assoc. is saying the smoke detectors must be electrically connected with one another mandated by the fire dept. and that we will be charged $40 for the replacement of our individual smoke detector. My question is, what is the difference in what I have now and something they say will be electrically connected when all of our alarms go off at the same time now. They say it is in case the electricity goes off. But isn’t that what the battery backup is for? Thanks.

TriSec asked:


All my detectors are hardwired with battery backup and installed new in the home 5 years ago. Well two of my detectors started the annoying chirp at the same time this morning. is it the battery or something else?

jimbob asked:


replaced to of the alarms. alarms are wired together on 110v system., with 9v battery backup. always start chirpping in middle of night.
alarms will chirp once each in rotation even with battery’s removed.
We are experiencing very high humiduty and heat could this be an issue
I guess I didn’t explain correctly, removing the batteries doesn’t stop the chirpping, you have to unplug the 110v wires. Do they go through some kind of auto check to see if there working? These are First Alert BRK models

Kelly U asked:


We have hard wired smoke dectors in our new house. There is no battery backup, but they keep chirping? How do we stop them?

Andre The Giant asked:


The new smoke detector code in Michigan, I believe is to have both AC electric with backup battery smoke detectors in every room.

Anyway.. we are having a problem with the smoke detectors that we’ve just recently installed:…

Are they supposed to beep like every 5 mins or is this just some kind of phase?

Is this fixable, if so… how?

Also, could someone please get me a link to Michigan codes for smoke detectors?
