Microphone Jack
The Host unit comes with a built-in microphone. Directly below the built-in mic is a separate jack
for connecting an optional condenser microphone to sense audible alarms, such as smoke detectors.
When an external microphone is connected, the internal microphone is disabled.
Rear Panel
The rear panel is where the main power switch is located. The main power cord attaches to the
IEC320 connector. The unit can be powered from 90–260VAC 47–63Hz.
ON/OFF Switch
The on/off switch connects main power and battery power to the system. Note that the system will
only turn on when main power is present. When main power fails, the internal battery will auto-
matically supply power to the unit.
