lisa system introduction
An alerting system requires at least
one transmitter and a receiver. The
transmitter captures sound signals
and transforms them into digital sig-
nals that are passed to a receiver by
the existing mains electricity supply.
The receiver then transforms these
digital signals into light signals.
Channel selection
A digital transmission system ensu-
res the correct recognition of each
of the digital signals from each
transmitter. The system has 10 diffe-
rent selectable 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 required channel
number using a small screwdriver.
Example:
Set channel
number 0
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 transmit-
ter from the socket and plug back in
again this time without pressing the
Personal Call button.
