Customer Reviews

I bought this unit to replace a prior model that was no longer available. It's installed in tandem with other smoke alarms as was its predecessor. It's less than a year old.
Since new, every few random months the unit chirps a random number of times at a random hour of the day - sadly, all but once at dark o'clock, waking up our little tykes. I've replaced backup batteries that test like new on my voltmeter, with new ones that also test positive, to no avail. None of the other units in tandem exhibit a problem. All units, including this one, work as designed when running periodic tests. The unit is neither dirty nor dusty. And I know it works in smokey conditions as my wife occasionally proves by talking on the phone and cooking at the same time.
It's just the kind of thing that makes you want to do something dumb like disable it.

I replaced all 9 smoke alarms in my house with the BRK2190B in about 20 minutes. The only reason I did not give it 5 stars is that the old ones were BRK (about 8 years old) that were starting to give false alarms (naturally at 2 or 3 in the morning). I have had them for a couple of weeks with no issues. The old ones did not indicate which unit had failed and was hard to trouble shoot). I had removed four of the 9 in the last year. All 9 of the new ones worked, and I had no issues. Only time will tell if I made the correct choice, but at least the BRK2190B will show me which unit caused the alarm. I have talked with other people with other alarms, and they all seem to have false alarms, so I am hoping the new ones work better. I admit I have not maintained them according to the manufacturer instructions, but who cleans them every month and test them every week.
