DESCRIPTION
Our Model DP2 Flush Mount Door Phone is specifically designed for connection to a
National Communications DS1-6 or DS-SIP Door Station Control unit.
It can be FLUSH MOUNTED (Both Versions) or it can be SURFACE MOUNTED
(DP2-V only) if the optional SMK2-V Surface Mount Kit is used (details on page 13).
DP2 has a 316 Marine Grade Stainless Steel fascia plate, which has 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 12).
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 direct rain.
The Speaker is made of a plastic mylar material and great effort has been taken to
maximise weather proofing all electronic components.
Whenever your Door Phone is likely to be exposed to RAIN, the optional DOOR
PHONE COVER or a SURFACE MOUNTING KIT with Rain Deflector should be used
(see pages 13-14)
All DP2 models can be mounted either horizontally or vertically but for aesthetic
reasons, they are also available with the BELL of the Touch Sensitive trigger area
orientated in a Horizontal or Vertical Orientation.
Our DP2 Door Phones can operate at distances of up to 300 meters from the Controller,
providing high quality cabling such as CAT5 is used, or 500m with the DS-SIP
Controller.
Our DP2’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.
Our DP2 units incorporate a ‘touch sensitive’ switch, in order to further improve it’s long
term reliability. 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 500-600 mm).
•
The Door Phone is mounted at a height of about 1.5 meters (5
feet). You can mount at a lower level to allow for very young
children, but volume will suffer.
•
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 use of ADSL with this product.

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
PBX 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. With this method, the party that talks LOUDEST will
take priority and will be connected to the other end.
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.
WHEN TESTING YOUR DOOR PHONE
DO NOT USE A TELEPHONE IN CLOSE PROXIMITY AS
FEEDBACK WILL CAUSE LOSS OF VOLUME.

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 can be fitted
vertically or horizontally.
To speed up installation, you may wish to purchase the
optionally available Galvanised 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 :
85mm, 190mm, D 40mm.
SURFACE MOUNTING KITS
Stainless Steel Surface Mounting Kits are available for our Model DP2
(Vertical) and DP5 Vertical Door Phones, so that your Door Phone can
be mounted ONTO a wall surface, rather than into it.
