1 Introduction

The DS Series Door Station series is intended as a hands free speaker telephone
situated at a door or gate and is connected to a suitable analogue extension of a PABX or
key system, such as the Datis Hitec Premier SOHO PABX. Pressing the button of the
Door phone will initiate the automatic sending of a DTMF number sequence which will be
analysed and handled by the PABX.

The DS Series is suitable for flush mounting in any wall with a cavity about the size of half
a standard house brick. A surface mounting bracket option is available.

2 Features

- Sealed to IP54 for protection against rain, water splashes and dust.

- Voice circuit is Line powered, so main function will still work if external power fails.

- External plug pack power required for Door strike and optional camera.

- Stainless Steel or Brass front panel options.

- Multiple button model to access different areas.

- Anti vandal construction

- Flush or Surface mount

- Electronic control of Volume and Microphone sensitivity to adjust unit to local

environments

- Improved Busy tone detection to suit most PABX types

3 Compliance

The DS series Door Station is fully approved and meets the Australian Communications
Authority (ACA) requirements for Electrical Safety, Telecommunications and
Electromagnetic Compatibility (EMC). Warning: The DS Series Door Station has been
designed for connection to a PABX and is not approved or intended for direct connection
to the Public Switched Telephone Network (PSTN).

4 Installation

4.1 Mounting the Front panel. Flush mount units should be fitted in a cavity size as
specified and fixed using wall plugs or other suitable fixings. Suggested hardware is
25X6mm wall plugs and 8G stainless steel “tamper torx” screws, which can be supplied
on request. Refer to separate instructions supplied with the various brass and stainless
steel front panels, surface mount brackets and plastic units.

4.2 Power Supply. The telephone section of the Door Station is Line Powered from the
telephone line. The Door Station will need to charge up when first connected to the line
– this may take upto 30 seconds. This charge will remain for a few days if removed from
the line. The Door Station relay driver and LED will require 15 to 24V DC (unregulated)
power or 15VAC power, rated at 500mA. This can be provided from the extension ports
of the Premier PABX itself (pair 2 power), or from a plug pack. The Premier’s auxiliary
power feed can be used to power both the Door Station’s LEDs and an optional Door
Strike coil, provided the Door Strike coil needs less than 400mA at 12V. There is
insufficient power from the Premier to feed the DS Series with the Camera option so an
external plug pack is required if the camera option is fitted. Summary of Power

4.3 Set up. Various parameters on the DS Series can be Programmed – refer section 4.
The DS Series Door Station by default sends the DTMF sequence #27 when the Door
Button is pressed (and #28 if the 2nd button is pressed on 2 button models). If connected
to the Datis Hitec Premier SOHO PABX, all telephone extensions will ring when #27 or
#28 is dialled. The Premier will need to be programmed if selected extensions are
required to ring. Refer to Premier Programming manual for information on how to
program selective ringing for extensions.

4.4 Door Strike. A door strike coil can be connected directly to the brown pair. When key 2
is pressed (programmable) on the remote telephone, upto 12VDC at upto 400mA will be
provided to the Door strike coil, for 3 seconds (programmable).

Independent contacts on the Green pair are also controlled by the Door Strike operation.
The Door Latch code and the duration of the relay ON time can be programmed – see
command list.

4.5 Cabling. The Door Station cabling should be installed according to AS/NZ 3086
“Telecommunications Installations – Integrated telecommunications cabling systems for
small office/home office premises”. If the Cable Tail wires will be subjected to weather
conditions, they should be connected using silicon filled telecom insulation displacement
connectors, to ensure weather proofing of the connections.

Brown Pair: Door Latch relay contacts. These terminals provide a nominal 10-12V

450mA DC supply to operate a Door Latch coil when the Door Latch code is sent.
These terminals can be connected directly to a door latch coil. These terminals are
protected from temporary accidental shorting. NOTE: Internal strap must be fitted.

Green Pair: Uncommitted Normally Open (NO) contacts. Door Latch relay contacts

that operate when the Door latch code is sent. These contacts are rated at 1A
30VDC. NOTE: Internal strap must be removed (unit is

delivered with strap removed).

Orange Power Pair: Power for the unit can be supplied:

(1) directly from the Premier PABX via pair 2 of the Premier’s

modular (RJ12) extension port. The inner pair (pair 1) of the

modular connector (RJ12) plug is the extension line pair.
(2) or from a 15 to 24V DC or 16-18V AC 500mA plug pack.
The Door Station power terminals are non polarized – the DC

cables can be connected either way.
Note: The voice circuit of the Door Station is line powered and will operate without

external power. The Plug pack power is required only to supply power to the LED and
the Door relay and external Door Strike coil, and optional camera if fitted.

Blue LINE pair: Voice Line pair. Connect a category 5 cable between the Front panel

unit and the PABX. The cable can pass through the premises’ Distribution Device
(DD).

Note: If using the Premier SOHO PABX, the Door Station can be connected to any
extension of the Premier, however it is suggested that extension 8 not be used for the
Door Station as this should be reserved for the emergency access telephone for use
when power fails. Refer to the Premier User Manual.

4.6 Volume and Microphone sensitivity Adjustment. Both Volume and Microphone
sensitivity can be adjusted remotely by command. This allows the unit’s parameters
to be tuned to suit the environment that it is in.

5 Programming

Various parameters can be programmed on the DS series Door Stations. A call must be
made into the unit with a standard analogue DTMF capable telephone. The unit must have
the answer strap fitted to answer the call. Commands can then be entered using the
telephone buttons to change the parameters. Changes survive power down.

Commands are started with *. Successful commands are acknowledged with 2 short
beeps. Failed commands or actions are indicated by 1 long beep.
