1.5.4 Connecting the Sensor device/Relay device /PTZ Camera
The Audio, Sensor, Alarm, and RS485 port enable you to connect 1 audio input device, 1 audio
output, 4 sensor inputs, 1 relay outputs, and PTZ camera. Just connect the external audio
input/output device, sensor, relay, and PTZ camera pin directly to the pinhole. Check the table
below and locate which pinhole is assigned to sensor input and relay output.
The signal from the sensor (i.e., infrared sensors, smoke detectors, proximity sensors, door
sensors, etc.) is being transmitted to the unit and this triggers the system to respond and
send signal to relay device (i.e., alarm, telephone etc).
