CUSTOMER REVIEWS

Rated 4 out of 5 by 1 reviewer.
Rated 4 out of 5 by Where there is no smoke - why is there an alarm? Okay - like most I purchased these to replace old dated detectors that were yellow or chirping or whatever reason. I have not had these that long - 4 months. I have read a lot of reviews that stated that the alarm was chirping for no reason - and it is nearly new - only way to hush them is to effectively disable them from any future use. Welllll.... not so fast, Although new - mine went off too - they are interconnected so all were involved (even the old ones that I had not replaced yet). But I also remembered that I had done some drywall work (albeit in the garage). It is a little known fact that dust (yes dust) collected in the detector can in fact give a false positive (especially in photoelectric types). The solution for me was get out the vacuum with soft brush and clean the detectors. It took me until the 4th one (which was closest to the garage btw) where when I cleaned it - shhhhhhhhhhhh the alarm stopped! So if your alarms are chirping and they are not approaching their end of life "chirps of death" telling us the sensors are past their useful life - just clean the things with your vacuum - and that might be all there is to it. If they are interconnected it could be ANY of the detectors that require cleaning. October 9, 2014
