2.6.1 Connecting the Sensor/Relay device to I/O card on NX8000 series
The I/O Audio card enables you to connect (4) sensor inputs and (4) relay outputs. Just connect the
external sensor and relay pin directly to the pinhole on the NX8000 card. Check the table below and
locate which pinhole is assigned to sensor input and relay output.

2.6.2 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 I/O card and this triggers the system to respond and send signal to
relay device (i.e., alarm, telephone etc).
