2.13 Connecting the Sensor/Relay device to NV6000 (EXP)/7000H/9000E 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 NV6000/7000H I/O card pinhole.
Check the table below and locate which pinhole is assigned to sensor input and relay output.

2.13.1
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 I/O card and this triggers the system to respond and
send signal to relay device (i.e., alarm, telephone etc).
