DESCRIPTION
This User Guide describes the installation and operating instructions of our
DS2 model DOOR STATION Controller, which is designed to connect to a
Specially designed Door Phone (see page 4), when used on an ordinary PSTN
residential telephone line.
Your DS2 Controller is completely TRANSPARENT in operation, so it will not
affect the normal operation of your telephone line in any way. It is designed to
RING all of your Normal Telephones when a visitor presses the Call Button of
the attached Door Phone. You need only Answer ANY Ringing Telephone to
converse with your visitor.
Model DS2 can also be used at sites which DO NOT USE A TELEPHONE
LINE. There is no requirement to have a LINE IN connection to DP2. Model
DP2 (Like models DS1 and DS3) outputs a ‘simulated telephone line’ via it’s
LINE OUT port which will allow ordinary telephones, including Cordless
Telephones to operate as Intercom Handsets. When used in conjunction with
Cordless Handsets, this results in extreme flexibility and save the considerable
costs of using (and cabling) multiple dedicated Intercom handsets.
DS2 can also be fitted to a PSTN TRUNK (used or unused) of any Multi-Line
PBX telephone system. See pages 16-17 for further details.
ONE or TWO Door Phones can be connected to the DS2 unit. They must be
connected in parallel with each other. Either Door Phone can trigger a Door
Phone call. If you use TWO Door Phones connected in parallel, then Audio will
be present at both Door Phones at the same time.
If you wish to operate 2 completely separate Door Phone zones, when using 2
Door Phones, you can do so by fitting an additional Model DS1 or DS2
Controller (depending whether the 2nd zone needs separate Lock Control) on
the same telephone line. In this situation, each Door Phone will then have
separate audio communication. This is our recommended solution.
Once correctly installed, DS2 will RING your all of telephones that are
connected to it as soon as it is activated by a visitor pressing the Call Button of
the attached Door Phone.

Natcomm Page 3
DS2 will work with both Corded and Cordless Phones. A small number of
Older Cordless Telephones may not ring differently as they are designed to
ignore the incoming ring pattern and output their own ring. For this reason,
your unit can be set to output FIVE quick ‘beep’ tones (advice tones)
immediately after answer, to advise you that the incoming call is from your
Door Phone.
OPERATION WITHOUT A TELEPHONE LINE
DS2 will also work WITHOUT connection of a Telephone Line. In this situation,
leave the Line Input port of DS2 vacant (see the diagram below).
DS2 will ring all attached telephones as normal. This will suit the many users
that no longer use a fixed telephone line. The diagram below shows a wiring
diagram used when a Single Lock Control relay is being used.

INSTALLATION FOR CORDLESS PHONE USERS
If you operate a Single Cordless Phone Base Station only, with 1 or more
handsets, then installation is very easy. See the Diagrams on pages 7-8.
1. Unplug the Base Station Telephone Cable from the Telephone Socket.
2. Connect this cable to the LINE OUT Port of DS2.
3. Connecting the LINE IN port of DS2 to the telephone using a supplied cable.
Installation by a technician is not required.
4. Arrange for a Suitable Qualified Technician to install your Door Phone in the
required location, following the Instructions supplied with the Door Phone.
MULTI SOCKET USE INSTALLATION
Installation is required by a Suitably Qualified Technician
Where you will operate cordless or corded telephones connected to more than
One telephone socket, an approved installation technician will need to fit your
DS2 direct onto your incoming telephone line, immediately ahead of your first
telephone socket, so that your telephone line connects to all of your telephone
sockets through it. See diagram on page 9.
DS2 has been designed so that it will not interfere with the normal use of your
telephone line in any way. In the event of a malfunction or power cut, your
telephone line will continue to operate.
Your DS2 unit should be fitted inside the home or office. If it is fitted outside
next to the Door Phone, then it MUST be fitted within a Water Proof enclosure.
These instructions are for suitably qualified Installation Technicians.
1) Locate the FIRST telephone socket on the line. Fit a New Telephone
socket next to it, or alternatively replace the Existing Telephone socket
with a Double Outlet RJ type telephone socket.
Label the Original Telephone Socket - LINE IN
Label this New Telephone Socket - LINE OUT

Natcomm Page 11
2) Transfer all of the Remote Extension wires from the Original Telephone
socket (now labelled Line In) to the corresponding positions on the New
Telephone Socket (labelled Line Out).
--------------------------------------------------------------------------------------------
A) Leave the original incoming Telephone Line wires connected to the
ORIGINAL Telephone Socket.
B) These Telephone Wires connected to the NEW Telephone socket (labelled
Line Out) are the connections to all of your EXTENSION telephones.
C) If a telephone is to be used at this same socket location, it should be
connected to the LINE OUT port of DS2, using a standard RJ style
Modular Double Telephone adaptor.
VERY IMPORTANT NOTE - LOSS OF TELEPHONE SERVICE
D) Should the DS2 device ever need to be removed, or if it becomes
faulty, you will lose your telephone service.
To overcome this, you should remove the cable from the LINE IN port
of DS2 and connect this cable direct to the new LINE OUT socket
(you will need to remove the existing cable connected to the LINE
OUT socket first). This will re-connect your telephone service.
--------------------------------------------------------------------------------------------
3) Now connect the LINE INPUT port of DS2 to the LINE IN socket, using
the supplied RJ to RJ telephone cable.
4) Connect the LINE OUTPUT port of DS2 to the LINE OUT telephone socket,
using the other supplied RJ to RJ telephone cable.
5) Connect the supplied 12VAC (or 12VDC) power adaptor to DS2, and
switch the POWER ON.
6) Connect the SUPPLIED DOOR PHONE to the DOOR PHONE PORT of
DS2. See page 12.
For convenience, a Connection Box with screw terminals is supplied and
should be connected to the DOOR PHONE PORT using the supplied RJ to RJ
cable.
Run a solid core telephone cable (preferably CAT5) between the interface unit
and the Door Phone. Now refer to your Door Phone User Guide.

CONNECTING THE DOOR PHONE
DP1 DOOR PHONE
Connect the two wires that are connected to the CENTER 2 PINS of the 8 pin
RJ45 socket of DS2, to the screw terminals located on the back of the DOOR
PHONE. Polarity is not important.
If you plan to use the interface unit, then the terminals for the GREEN and
RED wires should be connected to the screw terminals located on the back of
the DOOR PHONE. Polarity is not important.
The LED on the DOOR PHONE should turn ON (DS2 must be ON).
The DOOR PHONE should be mounted onto your wall surface. With DP1 this
is done by separating the Door Phone unit from the integral backing plate,
secured by a screw underneath the grey plastic label, above the speaker. The
backing plate should then be screwed to the wall surface, before re-attaching
the Door Phone with the securing screw.
DP2-DP5 DOOR PHONES
Audio Connection - Connect Pins 4 & 5 (the center 2 pins) of the 8 pin RJ45
socket of DS2 to the center 2 inputs of the supplied 4 position Phoenix Plug.
Polarity is not important.
If you plan to use the interface unit, then the terminals for the GREEN and
RED wires should be connected to the center 2 positions of the 4 position
Phoenix Plug. Polarity is not important.
Power Connection - Connect Pins 3 & 6 (the 2 pins either side of the center 2
pins) of the 8 pin RJ45 socket of DS2, to the outside positions of the 4 position
Phoenix Plug. Polarity is not important
If you plan to use the Connection Box, then the terminals for the YELLOW and
BLACK wires should be connected to the outside positions of the 4 position
Phoenix Plug. Polarity is not important.
The LED on the DOOR PHONE should now turn ON (DS2 must be ON).
Your DP2-DP5 unit should be screwed direct to the wall with the 2 supplied
mounting screws, or to the optional Surface Mounting Kit.

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 NEED TO MAKE ANY ADJUSTMENTS.
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 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 Potsettings.
4) The Balance POT does not increase volume. Moving it when
unnecessary may cause deterioration in audio quality or a loss of
audio in 1 direction.

14 Natcomm
LOCK CONTROL
Your DS2 is provided with an internal relay which can be used to control a
Door or Gate Lock. To OPEN the Door/Gate Lock after answering a call from
your DOOR PHONE you need to press ** on your telephone. The lock will
remain open for 10 seconds (Default setting). It can be set from 01-99 secs.
Your Door/Gate Lock can also be OPENED at any time by picking up any
telephone and dialling** . The Door/Gate Lock will remain UNLOCKED for 10
seconds (can be 01-99 secs).
You do not need to receive a call from the Door Phone first.
Relay Specification - Dry Relay Contacts rated at 12V/1Amp.
Do not use the supplied DS2 Controller 12V plug pack to also provide
12V power for the lock, as this may cause damage to DS2. You must use
a separate 12V source, with a maximum rating of 12V/1A.

Natcomm Page 15
USERS WITH ADSL
DS2 can be used with ADSL on the same telephone line.
However it is ESSENTIAL to fit a SINGLE High Quality ADSL filter immediately
ahead of the DS2 Controller. Failure to do so, or use of additional ADSL filters
connected direct to your telephones, WILL cause problems in the operation of
your DS2 Controller and ADSL service.
Please Note - Basic ADSL FILTERS, designed for separate connection to
each telephone on your line (as usually supplied with ADSL modems) are not
suitable.
If you use FIBRE, SATELLITE or CABLE for your Internet, you will NOT need an ADSL filter.
USERS WITH DIAL OUT ALARMS
DS2 can be used with a DIAL OUT SECURITY ALARM on the same
telephone line.
However to avoid conflict, it is ESSENTIAL to fit the DIAL OUT SECURITY
ALARM on the telephone line AHEAD of the DS2 unit.
If ADSL is also to be used on this same line, then it is ESSENTIAL to fit a
single High Quality ADSL filter immediately ahead of the DS2 Switch, being
the first point on the telephone line.
This means that the Security Alarm, DS2 Line Sharer and all telephones
connected on the telephone line have adequate filtering from the high
frequency ADSL communication.
FCC (USA) and IC (Canada) COMPLIANCE
This product has been tested and verified by an authorized independent
laboratory to comply with all Telephone Line and Electromagnetic Compliance
requirements for the USA and Canada. A separate page regarding
Electromagnetic Compliance and Radiofrequency Interference is supplied
separately with this product.

Page 16 Natcomm
MULTI-LINE PBX TELEPHONE SYSTEM USE
Our DS2 Line Sharer can be used with a PBX system in one of 3 ways:
1) Shared on the Last Line of a PBX
See Diagram 1 on page 17
DS2 can be fitted to ONE SPECIFIC INCOMING LINE of a Multi Line PBX type
system. In this situation, the incoming telephone line, prior to the system
controller should be connected to the LINE IN port of the DS2 Controller and
the LINE OUT port of the DS2 Controller should then be connected to the
system controller. Once fitted, the system will operate exactly as described
previously, for operation on the selected line.
2) Connected to an ‘Unused’ Line Input of a PBX System
See Diagram 2 on page 17
DS2 can also be fitted to an UNUSED TRUNK PORT or UNUSED LINE
PORT of ANY Multi Line Telephone System.
This means that this particular line WILL ONLY RING when the Door Phone
has been activated. In this situation, the LINE OUT port is the only connection
to the system controller. An incoming telephone line connection (or talk
battery) is not required.
3) On an FXO Port of an IP System
DS2 can also be fitted to an FXO PORT of an IP Telephone System.
4) Use a Model DS4 or DS5 Controller on an Analog Extension, or
an FXS or ATA port on an IP System.
Alternative Natcomm Controllers are available that are specifically designed for
use with a PBX System:
DS4 - For PBX Extension or FXS/ATA connection, no lock control.
DS5 - For PBX Extension or FXS/ATA connection, single lock control.
DS6 - PBX Extension or FXS/ATA connection, dual lock control, with dial out.

Default Setting is : OFF
NUMBER OF RINGS before stopping or initiating Dial Out
DS2 will ring your telephones 10 times when it is triggered by a Door Phone call. This
can be changed from 1-99 rings. DS2 has the ability to DIAL OUT to an external
telephone number or mobile number, if the call is unanswered after the programmed
NUMBER OF RINGS.
Allowable Range : 1 to 99 rings
Default Setting is : 10 rings
LOCK TIME OUT
The Lock relay control facility is used to open a gate or lock. You can set the time
which the LOCK will remain open after the user presses the ** command, to between
01-99 seconds. This is the time interval that the LOCK REMAINS OPEN after
pressing **
Allowable Range : 01 to 99
Default Setting is : 10
