2.8 Sensor and Relay pinhole allocation on I/O Card
2.8.1
NV6120T/NV6240T/NV6480T/NV8416T
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 NV6120T/NV6240T/NV6480T//NV8416T 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).
