When connecting the detectors to the LSN fire panels BZ500 LSN, UEZ2000LSN or
UGM2020, all detectors have to be addressed by CL00.
When connecting the detectors to the Modular Fire Panel FPA1200/FPA‑5000, the address
allocation is done automatically or manually.
In case of a manual allocation, all detectors of the same loop, stub or T‑tap have to have an
address between 001 and 254. Addresses between 255 and 299 are not allowed and produce
a fault message on the fire panel.
If the addresses shall be allocated automatically by the fire panel, all detectors must have the
address 000.
