We have had two alarm activations in the past month for no discernible reason. I'm not saying that the detectors are faulty or that the company isn't trustworthy, only that the particular detectors I installed were sounding alarms for no reason.
The detectors I ordered that I just installed are going in the garbage. I don't even feel comfortable donating these to Goodwill.
So if you're sitting there thinking that my home's wiring is to blame for the false alarms, read on.
While taking out the garbage this evening, I hear the distinct sound of a whole-home alarm activation from down the street. I walked down and found a home with it's front door wide open and the alarms sounding. Anyway, the home had the EXACT same brand of detectors as my home.
I guess if you're an optimist, you might be saying that the home builders obviously miswired every home on my block while they were being built. If you are a pragmatist, the inherent problem with these detectors is becoming more apparent.
I'm generally unimpressed with USI detectors. My house is 2 years old, and I've had to replace all but one of the original detectors supplied by the builder due to low battery chirping, even with a fresh battery, or false alarms.
