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.
