Advanced configuration
Warning
If the default settings (Table "Basic configuration") do not reflect requirements, the buttons can be programmed differently by
carrying out the steps below.
After programming, set S2 DIP switches 1-2-3-4 to the combination 1111. With these DIP-switch settings, the buttons
control the programmed functions.
The NON-programmed buttons control the basic configuration functions 0000. To restore the user code setting on
S1, see “addressing table”
Intercom calls: introduction
General and selective intercoms CANNOT be used together on the same riser.
General intercom: call from one internal unit to one or more internal units identified by the same call address as used
by the external unit.
Selective intercom: call from an internal unit to one or more internal units identified by a dedicated call address
(see "TABLE B") which is different from the call addressed used by the external unit.
Selective intercom address: programming/cancellation
Take note of the S2, S1 settings and restore on completion of programming

Intercom call: direct programming

Allows direct programming of intercom call via the internal units.
√√ Requires 2 operators
Step 1: enter programming mode
Operator 1 and Operator 2 carry out the following procedures on 2 internal units:
1. Set S2 DIP switches 1-2-3-4 to the combination 1111
2. Press the Audio button
3. Press and hold the Privacy and Lock release buttons for 3 sec.
»» The internal unit emits 1 tone.
»» The Privacy LED flashes
»» The internal unit enters audio mode.
»» At this point the 2 operators are in communication with each other.
Step 2: intercom call programming
Operator 1:
ff Press the button you want to program to call operator 2 (e.g. 2).
»» The internal unit manned by operator 1 emits a confirmation tone.
Operator 2:
ff Press the button you want to program to call operator 1 (e.g. 1).
»» The internal unit manned by operator 2 emits a confirmation tone.
Operator 1/Operator 2:
ff Press the Audio button
»» The internal unit emits 1 tone.
»» Programming of the 2 internal units is now complete.
To program another internal unit, go to STEP 3.
Step 3: programming other internal units
Operator 1/Operator 2:
1. Once the new station has been reached, carry out step 1 to begin communication.
2. Repeat step 2.
N.B. If a call is received during programming, it must be answered and the programming procedure resumed
afterwards.
