The detector features an ionization sensor for detection of smoke and fast-flaming fires, as well as a loud, 85-decibel alarm. One button silences any nuisance alarms, and also tests detector functions, while lights indicate if the alarm detects smoke. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. And an end-of-life signal enhances your safety by letting you know when it's time to replace the unit. Connect it to compatible BRK or First Alert alarms within a single-family residence. When one alarm is triggered, all connected alarms will sound. There are generally two types of smoke alarms - ionization smoke alarms and photoelectric smoke alarms. Smoke particles of a varying number and size are produced in all fires. Ionization smoke alarms are generally more sensitive than photoelectric smoke alarms at sensing small particles, which tend to be produced in greater amounts by hot, flaming fires, that are consuming combustible materials rapidly and may spread quickly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen. Photoelectric smoke alarms are generally more sensitive than ionization smoke detectors at sensing large smoke particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding. For maximum protection, use both types of technology, such as in the Dual Sensor Smoke Alarm, on each level and in every bedroom of your home.

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 ..
Most reviewers report random chirping. In my case, I replaced the battery and couldn't get it to stop chirping every minute, until I found this advice elsewhere on the web:1. Unplug detector from power (or flip circuit breaker)2. Remove battery3. Hold down Test button for 20 seconds4. Replace battery5. Turn power/breaker back onThis stopped mine from chirping every minute. Give it a try on yours.
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 pro..
