Operating principle
An alerting system consists of at least
one transmitter and one receiver. The
RF alarm transmitter picks up the
signals from various alarm sensors.
It converts theses signals into radio
pulses (868.35 MHz) and transmits
them to the receiver without the need
for wires.
Special features
When a signal is detected, a trans-
mission is sent out for a total of 22
seconds. This increases both the re-
liability and the range of the system.
Setup
1. Inserting the battery
There is a battery compartment on
the back of the RF alarm transmitter.
Open it by sliding the cover of the bat-
tery compartment to the right of the
receiver using your thumb. Connect
a 9 V block battery to the connector
plug, insert the battery into the batte-
ry compartment and close the device.
When the battery is connected, the
receivers may be triggered once.
2. Setting the correct radio channel
A special digital transmission process
ensures that the radio signals are pi-
cked up without errors. This process
also makes it possible to set 10 diffe-
rent radio channels.
All lisa RF devices are set to channel
0 by factory default. It is only neces-
sary to set units to other channels, if
you have several independent users
operating units in the same building.
Set the required channel by using a
small screwdriver to turn the channel
selector switch, which is located
