Notes
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.
Address setting
Use a slotted-head screwdriver to move the rotary switches to the required position.
Connection
Technical data
- 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
