Interconnected Smoke Alarm with Voice Location for Battery Operated, Pack of 2, WHITE

The FIRST ALERT SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location is equipped with an 85-decibel siren and voice alarm that informs you of the location of the danger. Its photoelectric sensor detects smoke while minimising false alarms from cooking or shower steam. The interconnected smoke detectors in different locations are designed to work together, with one alarm triggering the other alarms during a fire, providing the earliest warning for your family.

In the event of a fire, every second counts. With traditional battery-operated alarms, you may lose valuable time waiting for the smoke to rise to another alarm, on another level, before the alarm on your floor sounds. However, with First Alert ONELINK alarms, if one detects danger, they all sound. This can alert you sooner, increasing 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 ONE Link-with Voice Location Smoke alarm is programmable with up to 11 locations in your home - when the alarm sounds, it will tell you the location of the smoke. The wireless feature allows multiple alarms to communicate with each other, so when one alarm sounds, they all sound.

The wireless network operates on 914 MHZ 3 channels and will not interfere with other electronics. The ONELINK smoke alarms use photoelectric sensing technology, which is environmentally friendlier and reduces nuisance alarms, making it ideal for cooking areas. It is also great for detecting 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 are included.

Help keep your family safe with these battery-operated smoke alarms that wirelessly interconnect with each other and other First Alert enabled alarms, so that all sound when one is activated, creating a home safety network. The voice alarm with 11 programmable locations tells you where the danger is, allowing you to choose the best evacuation route.

The photoelectric smoke sensor is optimized to detect larger smoke particles produced by smoldering fires, helping to minimize the number of false alarms. The battery-powered alarm requires no rewiring for installation and provides continued monitoring even if there's a power failure. Use with Polaroid AA batteries for best results.

Wirelessly connect up to 18 First Alert enabled alarms for the maximum in whole-home protection. The alarm includes a test/silence button, low battery warning, and end of life timer. First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958.

Sensor Information: Smoke particles of varying number and size are produced in all fires. For maximum protection, use both ionization and photoelectric sensing technologies. Ionization alarms are generally more sensitive to fast flaming fires, while photoelectric alarms are generally more sensitive to smoldering fires.
