Rated 3.0 out of 5.0 by Nanammj One Defective
Had to replace all detectors (5)...found same brand online at HD. About a week after having new detectors installed, one went off, setting off other four. Thinking maybe wiring problem, hired electrician - determined one of new detectors was defective...ordered two more from HD (one as extra in case another problem)...electrician came back to install. So far, so good. Stuck with this brand because I wanted to make sure compatible with my monitored system. I said "yes" on recommendation because this may have just been a fluke - but was a very annoying one.

Rated 5.0 out of 5.0 by robert416 Always there, always alert.
When I had our house built recently, the design included a strobe light fire alarm system in order to better protect my deaf son. Unfortunately, the three initial alarm units developed problems with false alarms and/or no response at all when tested.. I replaced them with 3 USI Electric brand smoke & fire alarms. When the test button is pushed, all three USI alarms react reliably and consistently by sounding not only a loud alarm but also by triggering the strobe lights. Otherwise, they simply hand around on the wall letting us know with their little green power light that they are always there and always alert. What more could I ask for?

Better price at Home Depot than most places. Bought as a replacement for a system with inter-tied units. Works great, plugged in and mounts in place of older unit that would not stop intermittent beeping (tried replacing battery multiple times, clean/blowing out to no avail).
