Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by 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? April 15, 2014
Rated 5.0 out of 5.0 by nice replacement 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). February 11, 2014
