Congratulations on purchasing
the Doorbell Transmitter –
Galvanic. We hope it will give
you many years of reassuring
operation. 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
receiver. The transmitter captu-
res sound signals and trans-
forms them into digital signals
that are passed to a receiver by
the existing mains electricity
supply. The receiver then trans-
forms 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 selec-
table channels, 0-9. The factory
setting for all lisa devices is
channel 0. Only where more
than one installation is required
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 requi-
red channel number using a
small screwdriver.
Example:
Set channel
number 0
Personal Call button
Pressing this button causes a
certain flash sequence on each
receiver. 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.
