finally took batteries out of units so need to replace them later. detectors wer all sounding off now quiet for now. did some research and found out that if house is too hot or too cold, can cause this to happen. was wondering if this cold snap is causing it, anyone else having issues like this, any help would be appreciated.

My smoke detectors are hard wired in. But they also have battery back-up. About 5 years after building my home, my detectors started making a chirping sound. I replaced all the batteries. It happened again 5 years later and I again replaced the back-up batteries. Each time it fixed the problem.

It is about time for my chirps to return. I have a stock of Duracells ready to go.

One other thing - I have read that dust collecting on the sensors can cause the detector to go off. you might try one of the compressed air cans (used to clean keyboards, etc. if new batteries don't fix your problem.

Batteries become less efficient as the temperature drops. Auto batteries being a good example. I'm sure your batteries were very low to start with and combined with a drop of temperature inside the home caused the low voltage warning alarm to trigger. Replace batteries and all will be fine.

cleaned them, brand new batteries, even upped my thermostat a bit, and still going off. they are also hard wired, so you can imagine how loud 6 of these things are, anymore suggestions?

How long have they been installed? Long enough to accumulate dust? If so, I would blow them out with the covers off. If I remember correctly, the sensors cannot be cleaned by hand.....just by compressed air or a good vacuum.

thanks where would they be located? i am afraid to take them down because they will light up again, this has really been a pain since early this morning. thinking that maybe i should just disconnect so i at least get a goodnights rest tonight, and deal with it tomorrow.

Just doing a quick search on Bing, I came across this:

http://ask.metafilter.com/70031/False-alarms-...

It seems to me that the smoke detection chamber is a metal, puck shaped (but smaller) object that has a hole in it, visible when the cover is removed. That is what MAY need to be blown out.

Dust in the sensor is mentioned several times in the article.

Go on Bing and search for "smoke detector problems". When I did it, it gave me several options including "wired detectors that were giving false alarms". Good luck.

Good deal. Let us know if your detectors are still quiet after you have blown all of them out and replaced the batteries.
