DESCRIPTION
Our Model DP4 Flush Mount Door Phones are specifically designed for
connection to a Natcomm Door Station Controller (Models DS1-DS6).
DP4 incorporates a Low Light, High Resolution CCD Colour Camera, fitted
in a sealed plastic enclosure. The Camera Circuit uses a High Resolution
SONY sensor, which is designed to operate to at low light levels, where
moon light will provide good images.
Resolution: 380 lines
S/N Ratio: 46dB
Image Sensor: 1/4" CCD
Light Sensitivity: 2 Lux
A/V Connectors: BNC
The Camera is powered by the 4 wire connection to the Door Phone and
separate power is not required unless the DP4 is to be located more than
70m away.
If DP4 will be located more than 70m from the Door Phone controller, please
adviseNatcomm or yourDealer and aseparate 12V regulatedPower adaptor
will be provided at no charge. (see page 8).
DP4 has a BNC Video Output, suitable for direct connection to coaxial
cable. Optional CAT5 Video Baluns are available at extra cost, should you
wish to forward the video by 2 wires of a CAT5 cable. See page 9.
The Camera Lens provides a viewing angle of 92 degrees, and is fitted
behind a sealed 12mm transparent window.
DP4 has a polymer coated 316 Marine Grade Stainless Steel fascia plate
and can be mounted either horizontally or vertically.
Please order your unit set up for Vertical or Horizontal orientation, so the
Camera and the BELL of the Touch Sensitive switch are orientated
appropriately. Fitting this unit in the alternative orientation will cause the
Video image to be 90 degrees out.
There are 2 Models of DP4 :
DP4-V - Vertical Orientation
DP4-H - Horizontal Orientation

Our DP4 Door Phones can operate at distances of up to 300 meters
from the Controller, providing high quality cabling such as CAT5 is used.
Note - When located more than 70m from the Door Phone controller,
the Camera will need to use a separate power source by using the
supplied 12V regulated Power adaptor. This additional Power Adaptor
wil be supplied separately on request at no additional charge.
AllDP4unitsaredesignedtobehighlyWEATHERRESISTANTandthey
haveproventobereliableoverlongperiodsoftime,providingtheyarenot
exposed to direct rain. The Speaker is made of a plastic mylar material
and great effort has been taken to maximise weather proofing all
electroniccomponents.
Note - DP4 Door Phones are not WATER PROOF.
Whenever your Door Phone is likely to be exposed to RAIN, an optional
DOOR PHONE COVER or a SURFACE MOUNTING KIT with Rain
Deflector should be used. They will ensure that rain water cannot
gradually permeate through to the electronics of the Door Phone which
can cause unreliable operation and premature failure of this device.
See Pages 18-19.
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 connection).
Our DP4’s are 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.
OurDP4units incorporate a ‘touch sensitive’switch,in order to further
improveit’slongtermreliability.Thisswitchisactivatedbyabrieftouch.

CAMERA POWER
The Integrated Camera is powered direct from the Door Phone, which
receives it’s power via the 4 wire connection from the DS Controller.
However, the power consumption of the Camera is approximately
150 mA and this cannot be supported over distances greater than 70
meters.
When operating the Camera at distances greater than 70m from the
Door Phone controller, you will need to use a separate 12VDC regulated
Power adaptor to separately power the Camera. This additional Power
Adaptor wil be supplied separately on request at no additional charge.
INSTRUCTIONS FOR USE OF THE
SEPARATE CAMERA POWER SUPPLY
1. Remove the Power Cable connecting to the Camera assembly power
socket. Seal the removed cable and plug with waterproof insulating tape
to prevent future shorting.
2. Connect the Power Plug of the supplied 12V DC Regulated Power
Supply to the power socket of the Camera assembly. Connect the
supplied 12V DC Regulated Power Supply to a 240V Power Source.

CAMERA WIRING
DP4 provides a BNC output for Video, which can be connected to
standard TV’s, dedicated Video display units or both.
If IP Video is required, the DP4 video output should be connected to an
Analogue to Video IPConverter, such as the AXIS 241S.
You can use either Coaxial cable or CAT5 cable to connect video to
your Video display units.
As only 4 wires of an 8 wire CAT5 cable are required for the Door Phone,
4 wires are unused, unless One or Two Door locks are used in
conjunction with the Door Phone.
If only One Door Lock is used, then 2 wires are still available for Video.
If Two Door Locks are used, there will be no spare wires and a separate
CAT5 cable or a Coaxial cable will be needed for Video.
If you plan to use 2 wires of a CAT5 cable, then you will need to use a
pair of CAT5 Video Baluns to transfer the video signal. One Balun will
connect to the BNC output from the DP4 and the other will connect to
your Video display device.Asingle pair of CAT5 cable is used between
the Baluns.
Good Quality Baluns, such as those provided by Natcomm (see below)
will allow for good quality video over 100’s of meters of CAT5 cable.

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 DP4 unit is designed to be
recessed into a wall surface. It can be fitted
horizontally or vertically.
To assist installation, a Galvanised Iron ‘Wall Mount box’ (WMB) is
supplied which should be fitted within the wall cavity is supplied.
A recess area of : 255 mm, 93mm
and 40mm (D) should be prepared
for insertion of the Wall Mount Box.
Alternatively, a brick can be
removed. WMB is the same height
and width of a standard brick.
The Wall Mount Box should then be securely fixed within the recessed
cavity using nails, dyna bolts or silicone.
DP4 is then screwed onto the WMB by using 2 supplied stainless
steel screws.
SURFACE MOUNTING KITS
Optional Stainless Steel Surface Mounting Kits are available for all Natcomm
DoorPhones, so that yourDoor Phone canbe mounted ONTO awall surface,
rather than into it.
See page 18 for further detail.

OPERATION
After initial Power Up, the Door Phone will take up to 5 seconds to
initialise.
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 a Door Station Controller that will either
RING all the telephones connected to your telephone line or it will operate
with a PABX system.
As soon as the call is answered, you will be able to communicate with
loud and clear call quality.
If this Door Phone is connected to a Model DS6 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 prsent..
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.
For maximum clarity, it may be necessary to adjust the Balance
Pot (see page 12-13).
IMPORTANT NOTE
WHEN TESTING YOUR DOOR PHONE
DO NOT USE A TELEPHONE IN CLOSE PROXIMITY
AS FEEDBACK WILL CAUSE LOSS OF VOLUME.

islocated under
this sealing plug.
You will need to
use a small standard
bladescrewdriver.

National Communications Page 13
BALANCE POT ADJUSTMENT
Your DOOR PHONE is preset at the factory for maximum performance. Our
sophisticated circuitry is designed to measure the background noise present
at your site and then apply maximum gain.
In most cases you SHOULD NOT NEEDTO MAKEANYADJUSTMENTS.
If you are using Two Door Phones, 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 1 direction.
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 Door Phone.
2) Wait 10 seconds after answering before adjusting the Pot.
3) DO NOT USEA TELEPHONE IN CLOSE PROXIMITY TO THE DOOR
PHONE, as feedback interference will affect the Balance Pot settings.
4)The Balance POT does notincrease volume. Moving it when unnecessary
may cause a deterioration in audio quality or a loss of audio in 1 direction.

WIRING CONNECTION
Solid core cable such as CAT5 should be used to connect between the
DS Controller unit and the Door Phone unit. The DS Controller unit has
a standard 8 wire RJ45 connector. The Door Phone uses a 4 position
Phoenix Style plug.
Four wires are used to connect the Door Phone to the DS Controller
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 box with 8 screw terminals is supplied with your
DS Controller 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 Controller unit via the supplied short RJ45 cable. If Lock control
is not required, you will not need to use this box.
Where LOCK CONTROL is not required, you can bypass the connection
box and connect your CAT5 cable direct to the DS Controller. For details
see page 17.
There is a 4 position Phoenix Style 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 andTwo 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
outsideTwo positions of the socket.
Note : The polarity of the Audio
signal and power connections is not
important and can be reversed.

National Communications Page 17
The RED WIRE of the connection box, carries one leg of the Audio
Signal. It must connect to EITHER centre 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 centre 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 centre 2 pins of the DS Controller RJ socket need to
connect to the centre 2 positions of the DP2 Phoenix socket.
POWER CONNECTION (polarity is not important)
The 2 pins either side of the centre 2 pins of the DS Controller socket
connect to the 2 outer positions of the 4 pin Phoenix socket.
