Introduction
This multi-apartment door entry system allows you to wire up multiple
apartments that use a single public entry door to communicate with the
visitor.
The system can be supplied with 2 to 12 buttons on the door unit, and the
appropriate number o monitors

Door Unit Wiring Instructions
1. Connect the our-wire connections using 4-core cable. One cable
rom the door unit separately to each monitor
2. The two-wire connection provides power or a 12V DC lock.
Connect your lock (optional accessory) to the two wire cable
3. Ensure that correct polarity is observed or all connections
4. Do not make connections to the terminals whilst power is on to
any device
5. This unit is intended to be mounted into the wall next to the door
so that only the ace-plate is visible. You will need to remove
bricks, or cut a ixing hole or the mounting plate. It is possible to
mount it on the sur ace o the wall, but the security o your door
may be compromised by doing so.
6. Remove the covers o the 2 screws at the top and bottom o the
unit and ix to the wall.
7. The 4 metal brackets supplied should be itted through the holes
on the sides, rom the inside o the unit and ixed to the wall.
These create a vandal-proo installation

Monitor Controls
The VDP311 system is a lexible and user- riendly system that allows a
number o monitors to be used with a number o door units with cameras.
The monitors allow visibility o the callers via the camera in the door units
and, when used with the optional electronic lock, enable the resident to
electronically open the door or the caller.

Wall Mounting of Monitor
Fix the mounting bracket to the wall irst using the ixing holes (2), then connect
wiring and inally hook the monitor unit over the hooks (1) on the bracket.
You can use any 4-core cable to make the connections, but screened and/or
armoured cables are most secure.
The monitors are each provided with terminals and a short cable with
appropriate terminal connectors already attached. Use screw-type terminal blocks
to connect to these, or use a soldered joint i you are suitably experienced. You
can also purchase lengths o cable with terminal connectors already attached.
Connect similar colours together. That is, connect red to red, blue to blue, yellow
to yellow and white to white. The green wire does not need to be connected
(unless you have additional monitors or additional doors) and should be on the
le t o the terminal block when looking at the rear o the unit as in the image in
section 1.
A power adaptor must be plugged into the monitor. This will also supply power
to the door camera unit.
The (optional) electronic lock is connected to the door camera unit, using a twin
cable. Two versions are available: switched or powered – ensure you have the
correct version or your application.

2. Black (Ground)

Cabling to Monitors
There are two main types o wiring used with these systems: Cat5 and Screened
4-core cabling. Although both are ine or runs up to 30m, it is recommended to
use the screened cable or runs over 30m or so. There are two considerations or
this: voltage drops and inter erence. The biggest issue is the voltage drop.
Wiring using 4-Core Screened Cable
For this cable it is best to use the screen as the Ground conductor and then
double up with the Red and Black conductors. This reduces voltage drops
considerably.

P a g e 8
Wiring using CAT5 Cable
CAT5 cable consists o 4 pairs o twisted wires. For this to provide the required
inter erence shielding, it is important that one wire in each pair or audio and
video is a ground wire. As with the screened cable, it is also important to double
up the conductors or the Ground and B+ (power) lines as shown:
In some installations the +14V power required or each indoor monitor can be
provided rom a central place near the door unit. This can make or a neater
installation, but increases the voltage drop by a actor o two as the power needs
to run all the way up to the monitor and then back to the door camera unit. You
can use the spare conductor pair rom the previous diagram to run the 14V signal
to the back o the monitor. Note that the ground side o the power adaptor is
connected to the ground signal rom the camera, saving a conductor and allowing
both conductors to carry the +14V.
