4.2 Monitors
Every monitor is supplied with 6x 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.
4.3 Powering Cameras
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.
4.4 Powering Monitors
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.
