⇒ Following a successful system logon (duration:
15 seconds to a max. of 10 minutes), the LED will
go out and then flashes again for two minutes to
indicate the field strength.

⇒ The yellow LED lights up briefly to acknowledge
each successful logon.
D All RF detectors (maximum of 30) are logged on to
FK 100 LSN in this way one after the other.
D Wait until the LED (flashing to indicate field
strength) on the last detector goes out.
D Activate the RF expansion module by moving the
magnets along the left - hand side of FK 100 LSN
housing.
⇒ The green LED flashes slowly, indicating that
FK 100 LSN has started system configuration.
⇒ Following successful system configuration, the
green LED lights up permanently, indicating that
the radio cell is in standard mode.
Avoid disconnecting the expander power supply after initial set- up
of the radio cell, as all detectors search for their RF expansion mod-
ules during power off condition and are therefore constantly trans-
mitting, which substantially reduces the service life of the batteries.
If it is necessary to disconnect the power supply for a long period
(> 1 hour), remove the batteries from the RF detectors.
