3 V 915 MHz 85 dB at 10 ft Wireless Interconnect Battery Operated Smoke Alarm

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.
