Can't figure out how to change smoke detector battery

I don't have the manual so I loosened the unit from the wall to look at the back panel. It is hard wired with a battery back-up. The "plug in" part doesn't pull straight out--the edges fit into tiny slots on the side and there is a little flap that fits over the top part of the battery chamber. I can't get the battery out without getting the plug out of the way. I tried pulling the plug and sliding it up to disengage it, but no luck. The beeping is driving me crazy. Help!

My smoke detector is chirping even with new battery

Hello, Julie -

1. Try removing and resetting the new battery in the smoke detector.

2. If the smoke detector still chirps, I suggest just purchasing a replacement smoke detector unit.

We have a "main" smoke detector (along with others inside bedrooms and in corridors.) When the "main" smoke detector chirps, we have found we have to replace it, with a fresh battery, entirely. To make sure we purchase the right unit, we remove the entire thing from the ceiling mount and take it to the hardware store.

Best wishes.

I changed the smoke detectors with brand new ones but it is still chirping. Even if I turn the power off through the circuit breaker and remove the battery it still chirps every 40 seconds.

That can't be are your sure that is the detector that is making the noise .
No power the device can't operate .It chirps to let you know the battery is low even if it is hard wired.
The only thing I can think of that might make it do that is you didn't get the correct breaker and the connection that plugs into the back of the unit is damaged wires or pins are exposed and shorting .Seeing you changed the unit with a new one the chances of both units having the same problem are slim to none.
Check the connector you have to squeeze the sides its a bit tricky to unplug

New smoke detector, light flashing green, is that right

did you connect it to the electricity? this unit is not battery only; it requires connection to the household electricity. the only thing i could find in the manual makes it look like it's indicating low battery, but if it's not chirping once per minute as well then i would guess that it's looking for power

How do I fix a jammed battery compartment in a kidde i12060 smoke detector?

You could try to pry the door loose with a small screwdriver. To be safe, make sure the primary 110V power is turned off before trying to loosen the compartment door.
This is an inexpensive unit, less than $10, and is easily replaced if you can't get the door open.
If you do decide to replace it, you may want to look into a combination unit which monitors smoke and carbon monoxide if you don't have a carbon monoxide detector already in your home.

My Kidde Model 1285 keeps chirping even after I changed the batteries, any ideas why?

Be sure you are using a well known brand battery. The store brands, in my my opinion generally are not quite up to par. Try this and see if the chirp will stop. Thanks for asking me.

How to replace battery back-up in hard-wired ceiling mounted residential Firex Smoke Detector? Model number unknown but units about 10 y.o. - circular in shape and cream coloured.

Those battery holders are not easy to find on that model. However, look for a small screw on the outer perimeter of the detector. That's the door that needs to removed to replace the back-up battery. Some models don't have the screw, but can be popped open with gentle pressure using a flat tip screw driver.

Hope that helped to solve your problem.

One beep constantly on smoke and CO unit. says battery low but the system is wired into house panel. Help!

Most new smoke detectors work off of two power sources, electric and battery backup. The battery is used to power the detector if primary electrical AC power is lost. It would be a good idea to replace all detector batteries every two years or so. You'll access the battery by opening the unit, find out the type used and then purchase a replacement at your local store. Hope this helps.

Some smoke detectors are AC-only, so there is no battery. Dual-power units typically have the battery compartment on the back of the unit, where it attaches to the wall or ceiling.

Most units must be removed from their mounting bracket to change the battery, as the battery cover is on the back.

You rotate the unit about 1/2 turn counter clockwise, and it should come off the wall/ceiling. If it has an AC power connection, you unplug that so you can change the battery more easily.
