Install the
DOORTELLO LCD
doorstation at the desired place. All the electronic parts
are to be removed for the installation and the box has to be installed in the wall.
After this install the Doortello unit on the speaker module MD 10 with the delivered
screws. Connect the Doortello unit with the display unit using the provided cable and
board. Please take care about the correct connection on the plug of the display unit.
Connect the external PRS 220 power supply as indicated in the schematic. The
doortello unit has to be supplied with a 6 Vdc, the display unit with a 12 Vac. Connect
the doortello unit with your PABX using the telefone line (see also schematics). After
the cabling you have to program the electronic name directory. See the following
pages for the programming instructions.
After programming you should set the Hardware Timer (jumper J1 and J2, default 1
Minute). The device is now ready. Make a connection between door and telephone and
ensure that the volume are confortable for your need. If necessary you can regulate the
volume using the controls over the board. Please take care that you have to change the
volumes very carefully.
If the loudspeaker should send only "broken" speach
, or the
volume is too low,
try to reduce the microphone volume
. Please take care that
with
very high enviromental noise the device my have difficulties to recognize the busy
tone
. In this case you should take care that the unit must be disconnected using the
DTMF code 3 all times. Please take care that
max. 1 door opener with 40 Vpp 2 A
can be connected to the device. With more door to be opened at the same time or
larger current you must use a relais, like the ACI Farfisa universal relais 1471.
Connecting the device with your PABX you have to take care that:
-
DOORTELLO
does not have any type approval. You can use it only as an internal
device on your PABX. The connection to a public line, like using call divertion, may be
restricted in your country.
- If your PABX is using digital featurphones ensure that they have a DTMF dialling
capabilty also when called internaly. You need the DTMF dial to open the door.
