4. OPERATION AND USE
If everything has been connected correctly and power is supplied, programming and com-
municating is possible.
(Re)programming the system:
When programming the bell push buttons and the internal units, you can assign each bell
push button to 1 or 2 internal units (see '4. Technical data'). If you want to connect 2 or more
internal units in parallel, you will need the SERVICE SET (10-870). Conversely, you can as-
sign 1 internal unit to 1 or more push buttons. A bell push button can also be used to switch
the light. Programming is carried out via the power supply module and the internal unit. If
the internal unit cannot be reached, you can also program the system via the SERVICE SET
(10-870, see manual) or via a floor bell push button outside the premises. Programming and
resetting the push buttons is described in the manuals of the power supply modules.
Remark: All programmed data, as e.g. the serial numbers of the internal units to be cal-
led... are saved in the EEPROM memory of the flush type loudspeaker or the extension.
If these need replacement, the EEPROM memory can be transferred. Open the cover and
remove the EEPROM memory (see fig. 7a and 7b).

General operation:
- If the bell push buttons are programmed correctly (see above), the access control system
will operate as follows. When a programmed bell push button is pressed, a ring tone will
be heard both on the external and on the programmed internal unit. At the same time, the
green LED on the internal unit will light until the receiver is put down again. If a nonpro-
grammed or deleted bell push button is pressed, a short single beep will be heard and the
light relay in the bus control will be activated.
- If the receiver is not picked up, the connection will be automatically wound up after 60s.
and the green LED on the internal unit will go out. If the receiver is picked up within 60s.,
a voice connection is set up. The voice connection will be released 60s. after picking up
