Sensor/Relay Interface pinhole allocation
The I/O inteface enables you to connect (4) sensor inputs and (4) relay outputs. Just connect the
external sensor and relay pin directly to the I/O interface 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 I/O card and this triggers the system to respond and send
signal to relay device (i.e., alarm, telephone etc).
