PRODUCT DESCRIPTION
This User Guide describes the installation and operating instructions of our DS4
model DOOR STATION Controller.
It is designed to connect to a SPECIALLY DESIGNED Surface Mount or Flush Mount
DOOR PHONE, as described on page 3.
It is designed to connect to an ANALOGUE EXTENSION of a PBX or an FXS or
ATA port of an IP or Cloud Phone System
To use DS4, it is necessary that the Telephone System can be programmed to HOT
DIAL when the ANALOGUE telephone extension that it is connected to goes ‘Off
Hook’.
DS4 produces an ‘Off Hook’ condition when triggered by the attached Door Phone.
It will then remain ‘Off Hook’ until it detects standard AUSTRALIAN ‘Hang Up’ tones
from your telephone system.
If your Telephone System CANNOT be programmed to HOT DIAL, then you will
need to use our Model DS6 device, as it can be programmed to DIAL an internal
telephone extension or external telephone number.
ONE or TWO Door Phones can be connected to the DS4 unit (they must be
connected in parallel with each other).
If you use TWO Door Phones connected in parallel, either Door Phone can
trigger the Door Phone call and Audio will be present at both Door Phones at the
same time.
If you wish to operate 2 separate Door Phone zones, when using 2 Door Phones,
you should use an additional DS4 connected to an additional ANALOGUE telephone
extension. Each Door Phone will then have separate audio communication.

OPERATION
When a visitor at your door or gate presses the call button on the SUPPLIED DOOR
PHONE, DS4 will produce an OFF HOOK condition to the PBX.
The PBX system should be programmed to ‘HOT DIAL’ this connection to one or more
internal extensions or out to an external telephone number (which can include a
mobile cell phone).
Upon detection of the DS4 ‘Off Hook’, your PBX will AUTOMATICALLY connect the
visitor at the DOOR PHONE direct to one or more pre-programmed PBX extension(s).
Alternatively, the PBX may initiate an OUTGOING CALL so that the visitor at the
DOOR PHONE may be connected to an EXTERNAL SITE, or even a CELLULAR
PHONE.
Once the INTERNAL or EXTERNAL party answers their telephone, they will be
connected direct to the DOOR PHONE so that they may communicate with the
visitor.
If you require LOCK CONTROL via the Intercom Call, then you should use our
alternative Model DS5 Controller.
Once the CALLED PARTY has hung up, DS4 will detect the ‘hang up tones’ and then
terminate connection to the Door Phone.
Note - Due to the possibility that your PBX system may not output hang up tones, or
“AUSTRALIAN Cadence” hang up tones, a MAXIMUM CALL TIME has been set at
99 seconds.
This time can be changed to any value between 15 to 990 seconds. For further detail,
refer to the section - Programming Options on page 14.

INSTALLATION
Our DS4 Model Controller is designed to operate with a specially designed
DOOR PHONE (see page 3). A suitably qualified telephone technician will fit
your DS4 Controller direct onto an ANALOGUE extension of a PBX or direct
to an FXS port or ATA (ANALOGUE Telephone Adaptor) of an IP system.
1) Connect the PBX EXTENSION port of your DS4 direct to an
ANALOGUE Extension socket (or FXS-ATA), using the supplied
telephone cable.
2) Connect the supplied 12V power supply to your DS4, and switch the
POWER ON. Ensure that the green LED on your DS4 is illuminated.
3) Connect the SUPPLIED DOOR PHONE to the DOOR PHONE port of your
DS4.
4) Run a solid core telephone cable (preferably CAT3 or CAT5) between the
DS4 and the Door Phone. Maximum working distance is 300 yards (300
meters).
o DP1 Door Phone requires only 2 wires of the CAT3 or CAT5 cable.
o DP2-DP5 Door Phones require 4 wires of the CAT3 or CAT5 cable.
For your convenience, an interface unit with screw terminals is supplied
and should be connected to the DS4 unit using the short RJ to RJ cable
that is provided with it. Use of the interface unit is not required. You may
prefer to connect the CAT5 cable direct to the 8 pin RJ45 port of DS4. Pin
connections are described on page 11.
5) The PBX or other Multi-Line telephone system should now be
programmed to TRANSFER the DOOR PHONE call to the desired
destination (‘HOT DIAL’) once an OFF HOOK condition is detected on the
extension (FXS or ATA) to which the DS4 Controller is connected.
6) This should be done by a suitably qualified telephone technician that is
familiar with programming your system to ‘HOT DIAL’. The DS4 Controller
will automatically terminate the connection at the end of the call. See page
17 for further detail.

CONNECTING THE DOOR PHONE
Model DP1 DOOR PHONE
Our DP1 Door Phone can operate with 2 wires, but for superior Audio Volume and
Clarity, we recommend that you connect 4 wires from the DS Controller.
DP1 uses a Mini Socket on the back of the unit. You will need to strip back the plastic
sheath of all wires that connects to DP1 and push them firmly into the small Round
Hole. They will then be firmly held in position. To remove the cables, insert a small
screwdriver (or any thin piece of metal) into the Rectangular Hole beneath the Round
Hole. This will release the lever holding each wire in place.
Two Wire Connection - Connect Pins 4 & 5 (the center 2 pins) of the 8 pin RJ45
socket of DS1 to the center 2 inputs of the 4 position Mini Socket of DP1.
Four Wire Connection – Also Connect Pins 3 & 6 (the 2 pins either side of center 2
pins) of the 8 pin RJ45 socket of DS1 to the outer 2 inputs of the 4 position Mini
Socket of DP1.
DP1 is designed to 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 unit. The backing plate should then be screwed to the wall
surface, before re-attaching the Door Phone with the securing screw.
Model DP2, DP3, DP4 or DP5 DOOR PHONES
Audio Connection - Connect Pins 4 & 5 (the center 2 pins) of the 8 pin RJ45 socket
of DS1 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 DS1, to the outside positions of the 4 position Phoenix
Plug. Polarity is not important.
If you plan to use the interface unit, 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 turn ON (DS1 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.

TESTING THE DOOR PHONE
You are now ready to test the DOOR PHONE connection by pressing the Call Button
on the Door Phone.
Your PBX or other Multi-Line telephone system should now connect the DOOR
PHONE call to the correct destination. Have someone answer the call to
communicate.
Note - The Destination telephone must be located at least 10ft from the Door
Phone, or you may only have communication in 1 direction. If you are using a
Cordless Phone or Cell Phone, you may need to walk away until communication in
both directions is achieved.
Once you hang up, DS4 should disconnect the call after detection of 3 ‘Hang Up
tones’.
If the AUDIO Connection is not clear in both directions, you will need to adjust the
Balance Pot, as described on page 13.
TROUBLE SHOOTING
If your Phone System does not respond when you have pressed the Call Button on
the Door Phone, then you should:
•
Open the supplied Interface Unit and temporarily short across the internal screw
terminals connected to the RED and GREEN wires.
•
If the Phone System does not respond, it may not be programmed correctly.
•
You should remove DS4 from the ANALOGUE extension and connect an
ANALOGUE telephone or test phone in its place. You should only fit DS4 back on
the ANALOGUE extension once an ‘off hook’ by your ANALOGUE telephone or test
phone causes your telephone system to respond correctly.
•
If the Phone System responds correctly, then there may be a problem with the
cabling from the Door Phone to the interface unit. You should temporarily short
across the center 2 positions of the 4 position Phoenix plug which connects to the
Door Phone (or the 2 screw terminals if you are using a DP1). If the Phone system
does not respond, then you have a problem with the cabling back to the DS4 that
must be repaired or replaced. If the Phone system does respond, then you may have
a problem with the Door Phone. Call 07 5596 5128 for assistance.

UNIT PROGRAMMING
There are TWO user programmable functions as follows:
DISABLE HANG UP TONE DETECTION and ENABLE DTMF HANG UP
Your DS4 unit has been pre-programmed to detect AUSTRALIAN ‘Hang Up’
tones to determine when the call is complete and to terminate the call connection.
Due to the possibility that your equipment may not generate ‘Hang Up’ tones or
suitable tones, you can ENABLE DS4 to Immediately HANG UP by pressing ANY
DTMF Digit from 0-9.
If your DS4 does not automatically terminate on ‘hang up’ tone detection, you
should ENABLE DTMF Detection.
DTMF HANG UP : ON or OFF
Default Setting is : OFF
MAXIMUM DOOR PHONE CALL TIME
Due to the possibility that your equipment may not generate ‘Hang Up’ tones or
suitable tones, a maximum allowable time limit of 99 seconds is set for a Door
Phone call.
You can reduce this time setting if required :
Allowable Range : 15 – 99 seconds
Default Setting is : 99 seconds

PROGRAMMING NOTES
1)
To program your unit, you need to temporarily connect a standard ANALOGUE
Telephoned (or a Test Phone) to the PROGRAM PORT of your DS4 unit. All
entries must be made using this telephone.
2)
The PBX EXTENSION port of your DS4 unit MUST be connected to a telephone
extension (or you can alternatively use a normal PSTN line). This is so a
telephone line ‘battery feed’ can be connected to the Programming Telephone,
which will allow the attached Phone to generate touch tones.
3)
To enter PROGRAMMING MODE you must turn OFF POWER to your unit and
then switch POWER ON AGAIN.
4)
You must PRESS # within 30 SECONDS of reconnecting power.
You will hear 3 short ‘beeps’ to confirm you are in programming mode.
5)
Individual Parameter Programming Entries (A and/or B) are then carried out by
pressing further keys on the attached telephone (see below).
Notes
1. Parameters can be changed in any order.
2. After each entry, DS4 should generate 1 short ‘beep’ to confirm acceptance of
command, or 1 long ‘beep’ to advise of an entry error. If 1 long ‘beep’ is detected,
your command should be repeated.

Page 12 Natcomm

HANG UP AFTER DIAL OUT
DS4 incorporates a HANG UP TONE DETECTOR which is designed to detect
‘AUSTRALIAN’ specification hang up tones that will be present at the completion of a
Door Phone call. This process is fully automatic. Some PBX systems may generate
tones outside of the cadence and frequency normally used in the AUSTRALIAN for
Hang Up tones. In this situation, DS4 may not hang up until the Maximum Door Phone
Call Time has elapsed. Our Hang Up detector, looks for:
1.
A Tone Frequency between 200Hz and 600Hz.
2.
Tone Duration between 300mS and 600mS.
3.
A 50% Duty Cycle +/- 20% (ON and OFF periods should be the same +/- 20%)
If you are experiencing a problem with Hang Up, you should :
Adjust your PBX system to generate Hang Up tones as per the above specification,
or to output normal AUSTRALIAN Hang Up tones.
OR
You can set DS4 to HANG UP on Detection of ANY DTMF digit (0 to 9), from the Answering
Party once the Door Phone call is complete.
AND/OR
You can set the Maximum Door Phone Call Time to a time less than 99 seconds, but
which is still long enough to communicate with your visitors. DS4 will terminate all
Door Phone calls at this time setting.
ELECTRO MAGNETIC INTERFERENCE
Electromagnetic Interference (EMI) from some Switch Mode Power Supplies and some
low end UPS units (Uninterruptable Power Supplies) can prevent hang up tones being
detected by DS4. Switch Mode Power Supplies are easily identified because they
do not use a transformer and are very light. If you experience a problem, TURN OFF
any SWITCH MODE POWER SUPPLIES located near DS4 (and its power supply)
and test if the problem is resolved. If the DS4 Power Supply is connected to an
Uninterruptable Power Supply, remove it and test if the problem is resolved.

Page 14 Natcomm
TROUBLESHOOTING AUDIO
If you are having trouble with AUDIO COMMUNICATION between the DOOR
PHONE and your PBX Telephones, please follow the procedure below.
1. Adjust the POT located on the back of the Door Phone as described page 13.
2. If you are still having audio quality problems, they can be caused by EMI
INTERFERENCE from Switch Mode Power Supplies or some UPS units
(Uninterruptable Power Supplies).
Switch Mode Power Supplies can be easily identified because they are very light,
due to the fact that they do not use a transformer. Many brands of these power
supplies are well known to generate high levels of EMI.
Please TURN OFF any SWITCH MODE POWER SUPPLIES located near the DS4
controller (and its power supply) and test if the problem is resolved.
If the DS4 Power Supply is connected to an Uninterruptable Power Supply,
remove it and test if the problem is resolved.
3. If you are still having audio quality problems, then you may be picking up
interference (60 Hz power or other interference) via the cable travelling out to the
Door Phone. To test for this, you need to temporarily isolate DS4 from the existing
cable, using the following procedure :
Disconnect the telephone cable from the DOOR PHONE port of your DS4 unit and
then temporarily run NEW CAT5 cable from DS4 to your DOOR PHONE. Or
alternatively, remove the Door Phone from its normal position and move it closer to
the DS4 unit so that you can connect it using a temporary new CAT5 cable.
Please ensure this temporary test cable is no less than 30ft away from your DS4 unit
in order to prevent it generating feedback.
If satisfactory operation can be achieved, you should then fault find your problem in
the wiring leading to the DOOR PHONE unit.
