The Autronica BBR-52 SmartBuzzer for AutroSafe 3 is powered from the detector loop. As soon as the detector responds to an alarm signal, the SmartBuzzer will be activated.
The average sound level from the buzzer is 80dB. To further increase the audible coverage, the buzzer switches between two different sound frequencies. After 90 seconds the sounder will turn off, and remain locked in off-position until the alarm is manually reset from the system.
