Functions
The FLM-420-EOL4W EOL Module LSN can detect faults in the LSN line and auxiliary power in
accordance with EN 54-13, and uses the line to report an error on the fire panel's operating
panel.
The FLM-420-EOL4W is used to complete LSN loops and LSN stubs. Please use the FLM-420-
EOL2W EOL module to terminate LSN T-taps.
NOTICE!
The FLM-420-EOL4W cannot be used to terminate T-taps.

Installation must only be performed by authorized and specialized personnel!
Every end of the LSN bus at which 4-wire elements are connected must be terminated
with an EOL module.
Country-specific standards and guidelines must be observed during installation.
If loop wiring is present, the power supply must only terminate in the loop when ERT is
used. If no ERT system is present, the power supply must terminate at the FLM-420-
EOL4W module.
