If yours are hard wired capable, and they are not wired to a 120 service or your breaker is tripped they will chirp indicating a power loss. Just a thought.

Wiring the detectors with another circuit, say a lighting circuit, will prevent that from happening....

Re: Beeping Smoke Detector

I have four hard wired smoke detectors in my condo, I moved in (first person to live in this condo)late January. I have had beeping every night since from the two detectors in the bedroom and hall. The other two are quiet. All four units have been replaced twice with two different brands, new batteries put in and an electrician has checked the wiring. It has slowed down as the outside temperatures warm up. Has anyone come up with a solution to this? I am past the stage of it being a mild annoyance!

Re: Beeping Smoke Detector

smoke detectors are shipped with a thin,clear,piece of plastic seperating the battery from the connector. this keeps the battery fresh during shiping or storage. the strip should be pulled after installation. if the strip was not pulled you would see it hanging out of the battery compartment. however some times a part of the strip remains and does not allow contact from the battery. you can change the battery but if the obstruction is still there you will have a singing detector. Also you have two line voltage connections to check. the pin type that goes direct to the device and the pigtail between the supply wires and the pin connectors. check your pigtails for tightness. your pin connector should be flat and tight to the detector. Also some smoke detector ceiling boxes can have a whole mess of wires and wirenuts in them. be sure your pin connector does not get distorted when you mount the detector.

Re: Beeping Smoke Detector

I had this happen once in the middle of the night - on/off/on/off. Turned out to be a little spider running into and out of the sensor. Vacuum fixed it.

Re: Beeping Smoke Detector

had the same problem a year ago or so when i bought my house, i put in 4 hard wire/battery back up alarms. brand new detectors from mendards. same thing, theyd beep. i put new batteries in, didnt help. so i replaced one of them, with the same kind and that fixed my situation.. my personal oppinion, they make all this sh#t cheap and thats exactly what they are!! sometimes ya get a dud.
