2.12 Connecting an external I/O box to NV3000/5000 I/O card
i
The external I/O box is an optional item. It provides four (4) sensor input and three
(3) relay output.
Connect the male end of the D-type cable to the D-type I/O port of the I/O box and the female
end to the D-type port of the I/O card. Check the table below and locate which pinhole is
assigned to sensor input and relay output.

I/O box 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).
