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.
20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
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).
