Customer Reviews

At about 2:30 one morning I awoke to the faint sound of a smoke alarm beeping in my infant daughters room. To my suprise neither my wife, nor my daughter were awaken by the contiunous high-pitch whine of the 5 dollar smoke detector. Honestly, I don't know how long it had been alarming before I awoke. Fortunately it was a false alarm triggerd by a humidifier.
A few short days later (prime shipping) my new First Alert OneLink units arrived - I'd suggest buying 6 for a good size house and to make sure they are all in range to set each other off. They work on a mesh-type network, so when one receives a signal from the alarming unit, it will re-transmit the alarm again so any units out of range of the first unit also get the signal to alarm. It works well.
Setup is simple and the included mounts make it easy to hang them on the wall or ceiling. The first time I pressed the test button I knew NOBODY was going to sleep through an alarm.
About 6 months later I was proven correct. Something triggered one of the units - naturally it was in the middle of the night when we were asleep. All of them starting alarming (and yelling "evacuate! evacuate! smoke in basement"). They are LOUD. I'd suggest setting them off when your spouse is asleep and watching their reaction. Have some clean undies for them to change into afterwards.
The same unit did false alarm a few more times, and First Alert was quick to send me a replacement... They didn't hassle me for the box, receipt, or make me go through hoops to get a replacement. The (obviously USA based) phone representative sent me out a new one asap. It was the best customer service I've experienced in a long time.
If you don't have hard-wired alarms in your house, get these... don't be cheap.

I have a multi story house and wanted more protection and to know if there is smoke on another floor. These comunicate very well, They are a little hard to set up, it took multiple times before we were able to get them to talk to each other.. Don't loose your instruction sheet! you have to do it every time you change batteries.
