MAXIMUM EXTENSION OF THE SYSTEM
The sum of all the bus sections on main station bus side must be less than 800 metres. The sum of all the
door phone bus sections of a coupler must be lower than 800 metres.
POWER
Internal calling station circuits are power by bus voltage.
CONNECTIONS
In addition to the already connected button, up to 17 user buttons can be directly connected to the door
unit.
When a higher number of user is required, a 1083/17 expansion module can be connected. This allows
the addition of 16 user buttons to the 18 basic buttons. Up to four expansion units can be connected to each
door unit, for a total of 82 user buttons.
Position two call units side by side if a station with more than 82 users is required.
The door unit is programmed by default with a jumper between the earth and the “SP” signal to simulate
the door closed contact. Remove the jumper and connect the sensor between GND and SP when the open
door contact is required.
PROGRAMMING
In simple systems, the door unit can be programmed by means of the LED button and the two dip-
switches without the help of external devices. In complex systems and for special programming
needs, the device can be programmed with adapter 1072/60 to be inserted in the specic dedicated
minidin connector. The programming adapter must be connected to the programming keyboard
1032/65. The system must be powered for programming.
COMPLETE PROGRAMMING WITH EXTERNAL DEVICE
Insertion of the programming device is conrmed by two beeps and by the led lighting.
Parameters can be programmed or reprogrammed in any order until the keyboard is extracted. Two
beeps will be heard to conrm data programming. A KO signal (two beeps, the second of which at a lower
frequency) will be heard if the programming is not valid.
Repetitive beeps will be heard in programming if other modules with the same ID are present.
Press the button to silence the signal.
You are advised to program the data in the following order for the sake of simplicity.
System type
The digitiser can be congured as 1st edition or 2nd edition. The digitiser must be programmed as 1st edition
if there is even only one 1st edition device in the system (when replacing parts in old systems). The device
must be programmed as 2nd edition when all the devices in the system are 2nd edition.
Letter “M” identies the type of system:
Press M1↵ to program 1st edition
Press M2↵ to program 2nd edition
The device will repeatedly beep if there are other modules with the same ID. Press the button
to silence
the signal.
The two dip-switches must not be in the ON position to program this parameter.
