Congratulations on purchasing the
lisa Combi II. We hope it will give
you many years of reassuring ope-
ration. Please read through these
operating instructions carefully.
They tell you how to set up the
system correctly and explain all
the system's features to you.
lisa system introduction
An alerting system requires at
least one transmitter and a recei-
ver. The transmitter captures
sound signals and transforms
them into digital signals that are
passed to a receiver by the exi-
sting mains electricity supply. The
receiver then transforms these
digital signals into light signals.
Channel selection
A digital transmission system
ensures the correct recognition of
each of the digital signals from
each transmitter. The system has
10 different selectable channels,
0-9. The factory setting for all lisa
devices is channel 0. Only where
more than one installation is requi-
red in the same building will it be
necessary to select a different
channel for each system.
To select a channel, turn the rotary
switch on the underside of the
transmitter to the required channel
number using a small screwdriver.
Example:

Personal Call
button
Pressing this button causes a cer-
tain flash sequence on each recei-
ver. It is possible to call people in
other rooms this way. This button
also allows the lisa system to be
tested without any connecting
cables.
Duration of flashing signals
The factory setting for the duration
of the flash is 28 seconds for all
lisa receivers. However, you can
reduce this to 8 seconds if you
wish.
To change the flash duration for a
particular transmitter, remove the
transmitter from the mains socket
and, while pressing in the Personal
Call button, plug the transmitter
back into the socket. To switch
back to 28 seconds remove the
transmitter from the socket and
plug back in again this time
without pressing the Personal Call
button.
Doorbell connection
Plug the transmitter into a conve-
nient mains socket. Plug the door-
bell microphone lead into the
respective socket at the back of
