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 ensures
the correct recognition of each of the
digital signals from each transmitter.
The system has 10 different selecta-
ble 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 chan-
nel for each system.
To select a channel, turn the rotary
switch on the underside of the trans-
mitter to the required 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.
To change the flash duration for a par-
ticular transmitter, remove the trans-
mitter 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 with out pressing the personal
call button.
