Description
The doorstation with telephone line interface DOORTEL 4 can be connected to standard
analogue T/R extension lines of any PABX. The unit is delivered in four different versions:
the BG version for installation behind existing panels, the MD version with a designer
aluminium case, the AV version with a vandal proofed aluminum panel and the ES
version with a stainless steel casing. All versions can have up to four bell chime button.
The ES Version has only three button in his standard version.
The connection of the doorstation to the telephone switch is done using two wires.
Further a 12 Vac power supply is needed for the door opener and the illumination lamp
in the doorstation. For this another two wires are necessary. We suggest in any case to
provide an illumination of the doorstation as the lamps heat will ensure that the
condensing water formation and a too low operating temperature can be prevented.
Please take care that in some extrem enviroment situations the unit might need an add
on heating element. The device is deliverd with microphone and loudspeaker. The
volume of the loudspeaker and the microphone can be regulated.
The unit is activated using the bell buttons. Herefore a galvanic, powerless contact is
needed. Please take care that the activation LED will be lit only when the device is busy.
After the closing of one of the buttons contact the device will size the line, the red LED
will be lit, and the programmed telephone number is dialed using the selected mode:
rotary dial or DTMF. The telephone numer is programmed using a DTMF dial procedure.
The digits 0 to 9 and the special DTMF code * and # can be programmed as part of the
telephone number. Using the same DTMF dial procedure also all other programmations
are done. Only the setting for the dial mode, the hardware timer and the auto answer
are done using jumpers on the board.
If needed the DOORTEL 4 doorstation with telephone line interface can also be called.
As soon as the first call signal is recognized the unit will answer the call. After this an
acknowledge tone is sent to the caller.
During the connection using a DTMF dial pad telephone a door opener contact can be
activated dialing the "7". With the digit "8" a second optional contact can be activated.
The contacts are activated for a programmed time. And the end of this time the
connection is terminated automatically. This function can be deactivated using the
programming functions.
The connection will be terminated as soon as a busy tone is surley detected. The
DOORTEL 4 can be released, without opening the door, dialing the DTMF digit "3"
during the connection. If the called party doesn't answer the unit will drop the
connection after 7 ringback tones. For the enhanced security the unit has also a
hardware timer. This will ensure that the connection is terminated in any case after the
time out. The time out can be set to 1, 2 or 4 minutes using jumper which can be find
inside the unit.
The optional second contact, which is installed externally to the unit, can be

programmed also for an automatic mode. Is this case the contact is activated as soon
the line is sized, for all the seizure time, or just for the duration of 2 seconds. Herewith
videocameras, or similar devices, can be activated together with the unit. For the second
contact a relais unit 1471, 1471E or 1472 has to be installed. Furthermore the unit has
to be powered with a 12 Vac/dc supply.

Depending on the delivered version install the DOORTEL 4 doorstation as required. With
flush mounting versions the front plate and the installed electronic board should be take
off during the installation operations of the box. For the MD Version also for the wall
mounting version the front plate and the installed electronic board should be
dismounted for the installing operations. With the AV and ES version you can separate
the complete unit with front panel, back box and electronic board from the wall
mounting case. In this case you don't need to dismount the electronic board. With the
AV version with flush mounting installation do not forget to apply the delivered fitting
strip to the front panel.
With the BG version for installation behind existing panels, install the electronic board in
his case or letter box. Please take care that a too large distance between board and
microphone can reduce the voice quality of the unit. The bell button contacts are to
be connected powerless. With the installation of the loadspeaker and the microphone
please take care that enough acoustic separation between the two item is granted.
Especially the backward generated sound waves from the loadspeaker should not get
outside the case or reach the microphone. If the delivered installation holders for
microphone and loadspeaker are used, this should not be a problem.
If possible use different cables to connect the telephone line and the AC power supply
for the lamp and door opener. This will reduce the possibility to have "humming" noises
on the connection. After the installation and cabling using the in this documentation
provided connection diagram, the number to be dialled has to be programmed.Before
starting with the programming procedure the program enable jumper SW3 has to be set
on ON. Further also the dial mode jumper SW 4 has to be set on T (for tone dial) and
the jumper SW 5 for the auto answer has to be set on active. Both this last two setting
are foreseen as default from the factory. Now call the unit using a telephone with an
DTMF dial pad. Follow the programming procedure as described in the next pages. This
items can be programmed on the device:
- Program and delete the dial number for each bell button;
- Activation time for the contact 1 and 2;
- Automatic call termination after contact activation ON/OFF;
- Manual or automatic function for the contact 2;
- Pulsed (2 seconds) or continous activation of contact 2 with automatic function.
After the programmation of the telephone numbers you should select the appropiate
dial mode for your PABX (jumper SW4, default is DTMF). Further also the auto answer
function (jumper SW5, default ON) and the hardware timer (jumper SW6, default 2
minutes) should be set as required. The unit is now ready to work. You should set up a
connection with the door unit. A regulation of the sending and receiving volume may be
necessary. To do this you should use the regulators placed on the DOORTEL 4
doorstation. Please take care to regulate VERY carefully. If this is done by two people it
might be helpful. If the loudspeaker will send only "broken" tones, or it has a too

low volume, changing the volume of the microphone on the DOORTEL 4 may help.
With a very loud external enviroment the unit may be have difficulties detecting the
busy tone. This may happen also with tone which are not within the values as indicated
in the technical specification at the end of this document. In this case you should use
always the dial of the digit "3" to terminate the connection.
Please take care that if you need the external power supply the used transformer should
have an open circuit voltage of no more then 15 Vpp. We suggest the use of our
transformer PRS 210.
Please note that only one door opener with 40 Vpp and 2 A can be connected to the
build in relais of the unit. If you need to drive more door openers or if you need an
higher voltage or current you should use an external relais. We suggest the use of our
relais 1471.
Furthermore please consider this for the installation:
- If you are using digital sets or featurephones on your PABX please take care that these
are enabled to send DTMF tones also after an incoming call. You need this to open the
door.
