1.5.4 Connecting the Sensor/Relay device
The Sensor and Alarm ports enable you to connect (4) sensor inputs and (1) relay
outputs. Just connect the external sensor and relay pin directly to the pinhole. Check
the table below and locate which pinhole is assigned to sensor input and relay output.
1.5.4.1 I/O Card Sensor and Relay pinhole allocation:
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).

2 Sensor 1 signal
3 Sensor 2 Ground signal
4 Sensor 2 signal
5 Sensor 3 Ground signal
6 Sensor 3 signal
7 Sensor 4 Ground signal
8 Sensor 4 signal
