2.3 Sensor/Relay device pinhole allocation
The I/O card enables you to connect 16 sensor inputs and 4 relay outputs. Just connect the external sensor
and relay pin directly to the I/O card 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).
