Smoke Detector Problem

I have 4 electronic smoke detectors with battery backup on the same line. One detector beeps every 50 seconds non stop. I have already done the following: changed batteries, replaced with new detectors.

Even the new detector with new battery beeps every 50 seconds. So, it does not appear to be a problem of dust, battery, or new equipment. Where do I go from here?

Try taking the battery out, then put it back in & press the test button. It should beep back at you two times. If it doesn't, press the test button again. You may have to do this with every one that is hard-wired together. (03/18/2008)

Smoke Detector Problem

Changed batteries and smoke alarm is still chirping? Check to make sure you're using alkaline batteries. This happened with us. We bought the cheaper 9 volt battery, replaced the old battery and the blasted alarm still chirped for hours on end! Then realized it needed alkaline 9-volt. (07/18/2008)
