OPERATION
The A/V WARNING UNIT and the A/V Control Unit are electrically connected to form the BDS AUDIBLE/VISUAL WARNING SYSTEM. The Control Unit provides the audible and visual signals to the warning unit. Alarms are activated by remote switch closures (relay contacts) or by DTMF signaling. When alarm input #1 closes, the audible (Hi-Low) tone signal and the visual (Amber) strobe light are activated. When alarm input #2 closes, the audible (Yeow) tone signal and the visual (Red) strobe light are activated. When both #1 and #2 alarm inputs are closed, only input #2 audible will be activated (alarm #2 priority). No alarm is active when alarm inputs #1 and #2 are open. The system can function as an optional two (2) point alarm annunciator with an alarm acknowledge. When voice communication or Public Address (PA), announcements are necessary, the addition of a microphone with a push-to-talk button is required. Consult factory for details or special requirements.
