DESCRIPTION
Our Model DP2 Flush Mount Door Phone is specifically designed for
connection to a NATCOMM Model DS1-DS6 Control Unit,
(Called the Door Phone Controller).
It is designed to be FLUSH MOUNTED or it can be SURFACE MOUNTED
if the optional SMK2 Surface Mount Kit is used (details on page 14).
An optional inexpensive Galvanized Iron Wall Mount Box (Model WMB2) is
available to make Flush Mounting DP2 quicker and easier.
DP2 has a 316 Marine Grade Stainless Steel fascia plate, which has also
been coated with a tough transparent protective polymer material.
Other Door Phone models that are available are described on page 5.
Up to two of our Door Phones can be connected to the one DOOR
STATION (CONTROLLER). This allows for a Door Phone to be located at
two different locations. In this situation, the Door Phone devices are
connected in parallel (see wiring directions page 13).
All DP2 units are designed to be highly WEATHER RESISTANT and they
have proven to be reliable over long periods of time, providing they are not
exposed to extensive direct rain. The Speaker is made of a plastic mylar
material and great effort has been taken to maximize weather proofing all
electronic components.
Whenever your Door Phone is likely to be exposed to RAIN, an optional
DOOR PHONE COVER or a SURFACE MOUNTING KIT, which has a Rain
Deflector should be used (see pages 14-15).
Our DP2 Door Phones can operate at distances of up to 330 yards (300
meters) from the Controller, providing high quality cabling such as CAT3 or
CAT5 is used.
DP2 is designed for wall or pole mounting at a height of approximately 1.5
meters (5 feet). Visitors should stand within 0.5 meters (20 inches) of the
Door Phone for best results.
DP2 units incorporate a ‘touch sensitive’ switch, in order to provide for long
term switch reliability and as part of our weather resistant design. This
switch is activated by a brief touch.

DOOR PHONE PERFORMANCE
This product is IDEAL for RESIDENTIAL USE or COMMERCIAL USE,
where ROAD NOISE is NOT HIGH.
It is not designed for INDUSTRIAL USE where ambient noise can be
constantly high.
The volume of the audio communication on the internal phones
should be comfortably audible (a similar level to a telephone call)
providing:
• The person at the Door Phone is talking directly towards the
Door Phone and at a distance of no more than 1 to 2 feet away
(max 500-600mm).
• The Door Phone is mounted at aheight of about1.5 meters (5feet).
You can mount at a lower level to allow for very young children, but
volume willsuffer.
• No plates or other material are placed over the front face of the
Door phone. Our Door Phone Cover accessory, or a properly
designed Rain Hood will not affect performance.
The volume of the audio communication at the Door Phone should be
comfortably audible, providing :
• There is not excessive road noise or other noise near the Door
Phone. This will affect the automatic gain circuit used in this device.
• That high quality ADSL FILTERING is fitted ahead of the DS
CONTROLLER where ADSL is used on the same line. If you do not do
so, volume in both directions will be affected.
Refer to your Door Station Controller User Guide for detailed
information on the useof ADSL with this product.

OPERATION
After initial Power Up, the Door Phone will take up to 5 seconds to initialize.
Please WAIT 5 seconds before making your first call after power up.
To commence a Door Phone call, you should press the BELL on the Door
Phone briefly. The LED will then turn OFF and you will hear a RING TONE
until the call is answered.
This Door Phone will trigger the Door Station Controller which will either
RING all the telephones connected to your telephone line or it will operate
with a PBX system.
As soon as the call is answered, you will be able to communicate with clear
call quality.
If this Door Phone is connected to a Model DS3 Controller, you will also
have the ability to connect to an external telephone number, or cell
phone whenever the site is unattended.
Our Door Phones use an intelligent, fast switching ‘half duplex’
communication method, as this provides for highest volume levels and
eliminates feedback in areas with low to moderate background noise levels.
This method is not suitable for areas where high background noise levels
are present.
After your Door Phone call is completed, there will be a delay of
approximately 5 seconds before the unit has reset and is ready for the next
call.
A Door Phone Balance Pot is located behind a sealing plug on the rear of
DP2. Its position is Factory Set and will usually not have to be adjusted. For
some installations (such as when using 2 Door Phones in parallel), it may
be necessary to adjust the Balance Pot (see page 9).
WHEN TESTING YOUR DOOR PHONE
DO NOT USE A TELEPHONE IN CLOSE PROXIMITY AS
FEEDBACK WILL CAUSE LOSS OF VOLUME.

Page 8 Natcomm
MOUNTING THE DOOR PHONE
The DOOR PHONE should be mounted at the average face
height of 1.5 meter (5 feet) for optimum performance.
The main body of the DP2 unit is
designed to be recessed into a wall
surface. It is normally fitted vertically.
To speed up installation, you may wish to purchase the optionally available
Galvanized Iron ‘Wall Mount box’, which can be fitted within the wall cavity.
There are 2 sizes: Model WMB2 is
required for use with DP2.
The Door Phones are then screwed onto
the WMB by using the 2 supplied stainless
steel mounting screws.
When using the WMB2, you must allow for a recess area of :
(7.5 in x 3.4 in x 1.6 in) or (190mm, 85mm, D 40mm)
SURFACE MOUNTING KITS
Stainless Steel Surface Mounting Kits are available for all Model DP2 to
DP5 Door Phones, so that your Door Phone can be mounted ONTO a wall
surface, rather than into it. See page 14 for further detail.

Natcomm Page 9
BALANCE POT ADJUSTMENT
Your DOOR PHONE is preset at the factory for maximum performance.
Our circuitry is designed to measure the background noise present at your
site and then apply maximum gain.
In most cases you SHOULD NOT NEED TO MAKE ANY ADJUSTMENTS.
If you are using Two Door Phones connected in parallel, it is possible that
you will need to adjust the POT of one or both Door Phones to suit your
specific site conditions.
The balance POT is provided in case you experience one of the following :
• Audio is distorted.
• Audio (speech) can only be heard in 1direction.
Should you encounter one of these problems, you will need to make slow
careful adjustments in one direction or the other until speech can be heard
in both directions and without distortion.
The balance POT is located on the back of DOOR PHONE under a small
3mm removable black plastic plug. It should be adjusted using a small flat
blade screwdriver.
IMPORTANT NOTES
1) You will require TWO PEOPLE to adjust your DoorPhone Pot.
2) Wait 10 seconds after answering before adjusting thePot.
3) DO NOT USE A TELEPHONE IN CLOSE PROXIMITY TO THE DOOR
PHONE, as feedback interference will affect the Balance Pot settings.
4) The Balance POT does not increase volume. Moving it when unnecessary
may cause a deterioration in audio quality or a loss of audio in 1 direction.

Page 12 Natcomm
WIRING CONNECTION
Solid core cable such as CAT3 or CAT5 (when lock control is required)
should be used to connect between the DS Control unit and the Door
Phone unit. The DS Control unit has a standard 8 wire RJ45 connector. The
Door Phone uses a 4 position Dinkle plug (EC350V-04P).
Four wires are used to connect the Door Phone to the DS Control unit. Two
wires are required for each internal relay used for Lock control. A maximum
of 8 wires is required for installation, so a CAT5 cable is ideal
An external connection adaptor with 8 screw terminals is supplied with
your DS Control unit. The connection box provides a convenient
means of connecting the 2 or 4 wires used for 1 or 2 Gate or Door
locks to the internal relays of the DS Controller. The connection box
connects to the DS Control unit via the supplied short RJ45 cable.
Where LOCK CONTROL is not required, you can bypass the connection
box and connect your CAT5 cable direct to the DS Controller if more
convenient. For details see page 13.
There is a 4 position Dinkle press in connector socket on the rear of the
Door Phone, to which you connect the Audio and Power wires.
Two wires are required for the
AUDIO SIGNAL and Two wires are
used to provide POWER to the unit.
The Audio signal connects to the
middle Two positions of the socket.
The Power input connects to the
outside Two positions of the socket.
Note : The polarity of the Audio
signal and power connections is not
important and can be reversed.
Important Note : The colors referred to on this page and page 13 are
those of the wires in the supplied interface box.

Natcomm Page 13
The RED WIRE of the connection box, carries one leg of the Audio
Signal. It must connect to EITHER center position (pin 2 or 3) of the
supplied Phoenix plug. Note - Polarity is not important.
The GREEN WIRE of the connection box, carries the other leg of the
Audio Signal. It must connect to EITHER center position (pin 2 or 3) of
the supplied Phoenix plug. Note - Polarity is not important.
The BLACK WIRE of the connection box, carries one leg of the 12V
Power input. It must connect to EITHER outer position (pin 1 or 4) of
the Phoenix plug. Note - Polarity is not important.
The YELLOW WIRE of the connection box, carries one leg of the 12V
Power input. It must connect to EITHER outer position (1 or 4) of the
Phoenix plug. Note - Polarity is not important.
Where Two Door Phones are to be used, they should both connect to
the same contacts of the interface box (ie: parallel connection).
The ORANGE and BROWN WIRES of the connection box connect to
the Internal Relay used for Lock 1. Connect ONE leg of the 12V power
for Lock 1 to these terminals, by cutting the wire in half and fit one part
to the screw terminal connecting to the Orange wire and the other to
the screw terminal connected to the Brown wire. Polarity is not important.
The BLUE and WHITE WIRES of the connection box connect to the
Internal Relay used for Lock 2. Connect ONE leg of the 12V power for Lock
2 to these terminals, by cutting the wire in half and fit one part to the screw
terminal connecting to the Blue wire and the other half to the screw terminal
connected to the White wire. Polarity is not important.
BYPASS CONNECTION BOX
If you don’t plan to use the connection box, then you can connect the CAT5
cable direct to the DS Control unit and Door Phone, as follows :
AUDIO CONNECTION (polarity is not important)
The center 2 pins of the DS Controller RJ socket need to connect
to the center 2 positions of the DP2 Phoenix socket.
POWER CONNECTION (polarity is not important)
The 2 pins either side of the center 2 pins of the DS Controller socket
connect to the 2 outer positions of the 4 pin Phoenix socket.

SURFACE MOUNTING KITS
Stainless Steel Surface Mounting Kits are available for all Door Phones, so
that your Door Phone can be mounted ONTO a wall surface, rather than
into it.
Two separate surface mounting kits are available, to cater for the two
different sized Door Phones (DP2-DP5) that can be mounted vertically.
All kits have an integrated Rain Deflector.
oModel SMK2 : for DP2 units
oModel SMK3 : for DP4, DP5

DOOR PHONE COVER
If your Door Phone is not under cover, a strong transparent DOOR
PHONE COVER is highly recommended to ensure that water from
rain cannot gradually permeate through to the electronics of the Door
Phone which can cause unreliable operation and can eventually lead
to premature failure of thisdevice.
