13. Additional notes for the lisa -RF module
Operating principle
In cases of fire, the »RF smoke detector« A-2438-0 transmitts an alarm
signal (868,35 MHz) to RF-
lisa
receivers within range.
RF channel selection
A special digital transmission process ensures that the radio signals are
picked up without errors. This process also makes it possible to set 10
different radio channels. All »RF smoke alarm transmitter« are set to
channel 0 by default.
It is only necessary to set units to other channels if you have several
different users operating units in the same building.
To select the RF channel open the socket of the »RF smoke alarm trans-
mitter« and change the channel selector switch on the additional board
to the required channel number.
Test function
You can check the function of the RF transmitter module with the test
button on the additional board.
During this test the »RF smoke detector« transmitts a general alarm
signal to the receivers.
