4. PROGRAMMING and OPERATION
Programming the bell push-button
• Programming of the bell push-buttons is described in detail in the manual of the system
power supply (10-801, 10-802 or 10-806) or of the service unit (10-870).
• If you use the service unit, tear off the serial number to be found behind the nameplate under
the white foil of the external unit or the packing box, and stick it on the installation diagram.
• You can program up to 2 internal units in the memory location of each bell push-button. If
you want to program more internal units, you will need to apply master-slave progamming
to the internal units, as described in the service unit or internal unit manual.
• A non-programmed bell push-button will switch the light relay of the power supply.
