Replacing smoke detector alarm battery help

Can you see an indication of the brand and model number - to look on-line for instructions?

 

Squeeze the sides (clips) of the plug and remove it from the back of the detector. Replace the battery. Reinstall the plug - it should just push in. Reinstall the smoke detector in the ceiling.

 

How many other smoke detectors on same circuit?

 

If it continues to beep or chirp every 1 minute after replacing the batteries, then you may have a defective unit that needs to be replaced.

 

They may need cleaning in addition to new batteries. We've had the same alarm go off because of dust or fiber accumulation. Using a vacuum cleaner to draw out the foreign material worked.

 

You've changed both batteries?

 

Kitchen, BR. Bet there's another hiding in a closet, entryway, somewhere.

 

Smoke detector.

 

Water heater hiding in a closet off the bathroom?

 

This is the intermittent "beep/chirp" for low battery, not the "wake the dead/get out now" end of the world alarm noise? Check the area around the washer and heater for a hidden unit --- I've had a couple that the battery lasted for nearly a decade before the chirping started and took me literally forever to find.

 

Murphy's Law: something that requires the landlord or super is always going to happen after hours. Get the aeroduster and try A-nuc's cleaning trick. I'm out of ideas where to find a third alarm, and if that doesn't work, hope the landlord still has enough specs on the building to fix things.

 

For a "nominal" fee.
