Description - ATB-300 Audio Alarm
The ATB-300 provides audio failure alarm status contacts for each of the eight

least five seconds the respective relay will de energize. If audio is restored for at
least five seconds the respective channel relay will re energize. Relay 1-8
provide audio status for inputs 1-8 respectively.
