Wireless Interconnect Battery Operated Smoke Alarm w/ Voice Location

The First Alert Wireless Interconnected Smoke Alarm with Voice and Location detects smoke levels and can work with compatible models to create a wireless alert system throughout your home. This wireless-enabled battery-operated detector alerts you by using audible signals including a loud 85-decibel siren and that studies have shown to wake up children better than standard alarms. Wireless Interconnected technology allows other compatible First Alert wireless-enabled alarms located in separate areas of your home to communicate with each other, alerting you to a problem even when it's on another floor. This photoelectric smoke alarm includes tamper resistant locking pins that lock the detector to the mounting bracket and battery drawer to prevent removal of the alarm.

Can Be Connected with Compatible Alarms for Enhanced Safety

The First Alert SA511B Smoke Detector can be connected with multiple alarms around your home or office to create a safety network of detection (additional alarms sold separately). Compatible wireless alarms can communicate with each other through a radio frequency, so when one alarm sounds, all of them sound. Earlier notification of danger means you can avoid dangerous smoke levels sooner.

Battery-Operated Alarm Installs Easily

The battery-operated wireless interconnected smoke detector requires no wiring and no electrician to install. Simply put two AA batteries into the detector and mount it on any wall or ceiling. A low-battery light and chirp will let you know when the batteries need to be replaced. A one-touch button silences false alarms and allows you to test the smoke alarm for functionality.

Photoelectric Smoke Sensing

This smoke alarm uses a photoelectric smoke sensing sensor that provides optimal protection from smoldering fires. Photoelectric smoke alarms also reduce the likelihood of false alarms like those caused from cooking fires and shower steam from sounding.
