1. Introduction
The DCC1/DCC2 Door Entry System enhances entry security by enabling the user
to recognise the visitor by audible and viisual means before openiing the door.
The external intercom incorporates LED lighting to illuminate the visitor for the
camera. This type of lighting has an indefinte life.
An electric door catch (not supplied) is available as an optional extra for the
DCC1/DCC2 to make the door opening automatic.
The external and internal intercoms are connected by a four core cable. With
the cable supplied the distance between these units is limited to 15m. By using
a larger core diameter cable this distance can be increased to a maximum of
100m, see section 9 (specifications) for further details.
2. Product Overview
If operation with an electric door catch is required then part DCLR is a fail
(power off) secure catch available from Timeguard. It requires an additional
mains adaptor part DCADAP to enable operation. See fig 2 for wiring of these
parts. An additional two core cable run (using 13/0.2 bell flex) will be required
between internal intercom and door catch via the additional mains adaptor.

3. Selecting intercom sites and cabling
3.1 Intercom sites
The internal intercom should be located at a convenient position for all potential
users at the height indicated in fig 3a and at a maximum distance of 70m from
the external intercom. If all the users are significantly above or below average
height then a different mounting height may be considered appropriate.
The external intercom should be sited in an area away from driving rain
and surface water, out of direct sunlight as far as possible and protected by the
minimum of an open porch in a position readily accessible to potential entrants.
It should be mounted at the height indicated in fig 3b.

3.2 Cabling
Connection between the internal and external intercoms is by 4 core cable. A
15m length is supplied.
A separation of intercoms up to 100m is possible, refer to section 9
(specifications) to see how cable core diameter needs to be increased with
increasing separation.
The cable run should be kept at least 100mm away from any mains cable.

4. Fixing Intercoms
4.1 External intercom
Important: To give the best possible waterproofing and appearance we
recommend taking the wiring through the exterior wall directly behind
the external intercom so that the cabling will feed directly through
a back box cable knock out. If the surface to be fixed to is not even
(e.g. pebbledash or brickwork with raised pointing) we recommend
the use of at least 10mm (3/8") thick marine ply as a mounting plate
between the wall and the back box to prevent its distortion and loss of
waterproofing.
i Remove the back box from the external intercom in the following way. Insert
a small screwdriver blade in the end cap screwdriver notch (fig 4, i) and lever
end cap so that it slides outwards from the main case (in opposite directions
to those shown in fig 4, iv). Remove the two fixing screws (as shown in fig 4,
iii) and remove the back box from the rear of the external intercom.
ii This is a convenient time to mark the nameplate.
Referring to fig 5, remove screw holding the PCB assembly to the transparent
housing. Lever one of the catches on the transparent housing clear of the
PCB assembly and lift the PCB assembly clear of the transparent housing.
Lever out the diffuser and nameplate from the transparent housing.
Mark the nameplate as required with a permanent fibre-tipped pen. When
dry insert the nameplate into its recess in the housing ensuring it is the right
way up. Replace the diffuser on top of the nameplate and push the PCB
housing to engage with the catches of the transparent housing. Replace the
screw holding the transparent and PCB housings together.
iii Offer the back box up to the required position on the wall (refer to section
3.1). Decide which of the cable knock outs is to be used. Score around the
groove with a sharp knife and push the centre out. Feed the 4 core cable
through this knock out in the back box (see fig 4, ii). Mark the positions of
the four fixing screws (no 8 roundhead) using the back box as a template
(see fig 4, ii). Remove the back box, drill and, if necessary plug holes.
Feed the cables through the wiring slot. Fix the back box to the wall with
No. 8 roundhead screws.

4.2 Internal intercom
Choose a position which can be reached easily by all potential users. If one
person usually in one location will be the main user it may be considered
appropriate to locate the internal intercom within reach of that person.
Mark out two holes suitable for No. 8 roundhead screws using the wall
mounting plate as a template (ensure this is the correct way up by referring
to fig 6).
Drill and plug the holes if necessary. Offer the wall fixing plate up to the
wall and drive the fixing screws home, ensuring the plate is not distorted by
mounting on an uneven surface.
Connect the four core lead from the external intercom according to fig 2. Plug
the mains adaptor low voltage plug into the mains adaptor socket (see fig 1).
Arrange the two cables at the back of the internal intercom. Finally locate the
internal intercom mounting slots on the wall fixing plate mounting hooks, and
slide intercom downwards into position.

5. Commissioning/Use
Press the call button (fig 1c, d) at the external intercom – a buzz will be
heard locally and the camera will activate for 1 minute. A ring tone will be
heard at the internal intercom for two to 3 rings and the display will show
the visitor.
Once the handset is lifted two way communication is possible via the
microphone and speaker at the external intercom.
The video on button (fig 1a, 6) when pressed will give a minute of camera
and display active at any time. This can be brought to an end earlier by
pressing the video off button.
To end the conversation and turn off the camera and display replace the
handset on hook.
Finally, if a door catch is fitted, the door open button (fig 1a, 4) should be
pressed and, the door can be opened.
It is not necessary for the handset to be lifted to use the door open faciliity.
If necessary the audio volume, video brightness and video contrast can be
adjusted using the controls 8, 9 and 10 respectively (fig 1b).
