The rotary switches are moved to the required position using a slotted-head screwdriver.
Automatic address allocation
If addresses are automatically allocated by a fire panel with LSN improved version technology,
all detectors must have the address "0 0 0" (delivery status).
For connection to classic LSN fire panels (BZ 500 LSN, UEZ 2000 LSN, UGM 2020), all
detectors must have the address "CL 0 0".
Manual address allocation
For manual address allocation, the detector address is set with the three rotary switches. The
right-hand rotary switch is used to set the units, the central rotary switch is used to set the
tens and the left-hand rotary switch is used to set the hundreds.

Notice!
It is not permissible to use addresses greater than 254.
This will prompt the display of an error message on the fire panel.
All the detectors in a loop, stub or T-tap must have an address between 1 and 254 when ad-
dressed manually.
From LSN module software version 1.0.35, you can operate LSN improved version and LSN
classic elements together in one loop or stub. If an LSN classic element is present, only 127
elements can be used in the loop.
Please note that only loop or stub structures can be used for configurations with mixed LSN
classic and LSN improved elements.
