First Alert SA501CN ONELINK Wireless Battery Operated Smoke Alarm In the event of a fire every second counts. If a fire were to begin in your basement and the alarm there sounded, you may not hear it right away if you're sound asleep two floors up. With traditional battery-operated alarms, you lose valuable time waiting for the smoke to rise to another alarm, on another level, before the alarm on your floor sounds. But with First Alert ONELINK alarms, if one detects danger, they all sound. This can alert you sooner, and it increases your chances of getting out safely.
Until now, alarms that could signal each other were only available in homes with hardwired alarms requiring installation from an electrician. But First Alert ONELINK alarms communicate without wires.
The First Alert ONELINK SA501CN alarm uses photoelectric sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. A low battery signal alerts you to replace the battery. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The AA batteries are easy to install in the convenient pullout battery drawer. Two AA batteries included.--Bree Norlander

Don't waste your money! - A. Thomas - San Diego, CA
Ordered a two pack, set them up between a bedroom and the garage in a single story, 1958 California home, 50ft distant (read: cheap thin walls with no insulation). They will not communicate between each other at that distance. Re-initialized them just in case, still a no go. I let them sit like that for a month. Just tested them again: no go.
Moved the one in the garage to the hallway just outside the bedroom one, worked fine. Moved it down the hallway to the living room (15 feet distance, one thin door separating them): no go.
Took them outside: max communication distance is about 25 feet line of sight. Past that, no go.
Bottom line, these do not work as advertised. Don't waste your money. I know someone who has the Kidde equivalent and she swears by them. I might try those out next.

I installed eight of these and it was a simple process. All eight are in sync and work well. They are much better than the low cost units they replaced.
