2.7 Sensor and Relay pinhole allocation on NX8000
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).

2.7.1
Connecting the Sensor/Relay device to I/O card
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.
