Intercom System (for a/b)
The “Doorphone” intercom system can be connected to any a/b
port. The “Doorphone” module also provides the actor for the door
opener contact.
Please observe the following points when connecting the door
intercom system:
z The “Doorphone” module should be set to its factory setting.
z In the Telephony: Ports: a/b: Change menu in the
Configurator, select Doorstation 2-wire as the Type.
Deactivate the Actor option if you want to use the Forum 523/
524 actor port instead of the “Doorphone” relay to open the
door.
z The “Doorphone” intercom system has a number of bell keys
to which you can assign various call numbers in the
Configurator under the menu item Telephony: Ports:
Doorbell.
z You can call the “Doorphone” intercom system by using the
code procedure
*102.
z The “Doorphone” can be connected to any a/b port, but you
can only operate one “Doorphone” intercom system using
Forum 523/524.
You will find more detailed information on installing and configur-
ing the “Doorphone” intercom system in the product’s user guide.
The intercom system should only be connected by a skilled electri-
cian, because sensor/actor contacts must be connected to the
“Doorphone” module.
Actor
Forum 523/524 can be connected to a door intercom system of
the “Doorphone”. This intercom system is connected to one of
Forum 523/524’s a/b ports via the “Doorphone” module (see
Intercom System (for a/b) starting on page 57).
The actor port also makes it possible to connect a separate door-
opener. To do this you will need a twin-wire connection cable.
