Firefighter Smoke Audio Sensor – 319.5 Mhz Compatible

FireFighter’s unique technology monitors the alarm activity of existing UL smoke detectors. When an alarm is detected, a wireless signal is sent to the control panel which in turn notifies the central monitoring station. With interconnected hardwired smoke detectors found in most homes today, only one FireFighter is needed to monitor these detectors.
