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.
