Connections and Wiring

3.2 Monitors

Every monitor is supplied with 5x 4 wire y-leads, 1x 2 wire y-lead and 1x 3 wire y-

lead.

The 4 wire y-leads are terminated into 4 pin plugs which are simply inserted into the

sockets on the rear of the monitor. These are used for connecting door cameras,

auxiliary cameras and auxiliary monitors, the 4 wires are colour co-ordinated to

match the 4 wires from the door camera.

The 2 wire y-lead is terminated with a 2 pin plug and is used as the TV out for

connecting the door monitor to a TV monitor or DVR.

The 3 wire y-lead is terminated for the local relay plug and is used to unlock a local

relay like a door release local to the monitor.

Door cameras and auxiliary cameras can be powered in two ways, either locally or

via the main monitor.

The DoorKnox monitors can supply a 12V DC output to any of the four cameras but

can only supply a maximum of 400mA across all outputs.

To power a camera locally connect the Audio (white) and Video (yellow) to the door

monitor, the GND (black) to the PSU and the door monitor and then the 12V DC (red)

to the PSU only.

Door monitors are supplied with a 12V DC 2A plug-in PSU that terminates into a 2

pin plug which slots into the rear of the monitor.
