Doorphone devices are connected to the Control Unit via terminals on its PCB.
To perform connections, remove the lid from the Control Unit.
Terminal and their destinations are given in the following table:
The Control Unit is connected to the mains by means of its mains cord.
Acceptable cross-sections of wires used for connections depend on their length
(see the following table):
* -
– Control Unit
,
– doorstation
,
– commutator.
Use a
coax cable for video trunk line between the doorstation and commutators. To avoid image distortion,
connect an
resistor to
and
terminals of
commutator or
video amplifier, which is the last in the
video circuit.
Wiring diagrams are given in the
section.
There are two programming modes:
and

.
This setting determines the
and should comply with a lock type used:
Electromagnetic lock (
) releases, when

(1 to 12 seconds).
Default setting is
– acceptable for electromagnetic lock.
setting is recommended for an electromechanical lock.
.
Priority determines order in which doorstations switch to the intercom line of a doorphone consisting of 2 doorst 2
control units and a concierge console, when 2 visitors make calls to subscribers while the line is engaged by a concierge.
A control unit with
