Consumer Reviews
I purchased this unit to replace a prior model that was no longer accessible. It's installed in tandem with other smoke alarms as was its predecessor. It is less than a year old.
Because new, each and every few random months the unit chirps a random quantity of occasions at a random hour of the day - sadly, all but when at dark o'clock, waking up our tiny 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 difficulty. All units, such as this 1, function as developed when operating periodic tests. The unit is neither dirty nor dusty. And I know it operates in smokey conditions as my wife occasionally proves by talking on the phone and cooking at the similar time.
It's just the type of factor that tends to make you want to do some thing dumb like disable it.
I replaced all 9 smoke alarms in my residence with the BRK2190B in about 20 minutes. The only cause I did not give it five stars is that the old ones were BRK (about eight years old) that had been beginning to give false alarms (naturally at two or three in the morning). I have had them for a couple of weeks with no concerns. The old ones did not indicate which unit had failed and was tough to difficulty shoot). I had removed 4 of the 9 in the final year. All 9 of the new ones worked, and I had no issues. Only time will tell if I produced the correct choice, but at least the BRK2190B will show me which unit caused the alarm. I have talked with other many people with other alarms, and they all appear to have false alarms, so I am hoping the new ones operate improved. I admit I have not maintained them according to the manufacturer directions, but who cleans them just about every month and test them every week.
