FLM-420/4-CON Conventional Interface Module for 4-wire LSN
Functional description
The FLM-420/4-CON Conventional interface module enables monitored connection of conventional detectors to LSN
fire panels via a 4-wire supply network (LSN with external power supply).
The surface-mount housing for the FLM-420/4-CON-S has pre-formed conduit connections and rubber bushings for
cable entries (Figure 2, page 7, Removal: Figure 1, page 6, Installation: Figure 5, page 9).
The FLM-420/4-CON-D is installed on a DIN rail in accordance with EN 500022 with enclosed adapter (Installation:
Figure 6, page 10; Removal: Figure 7, page 11).
Address setting
Fit a rotary switch in the required position using a pan head slotted screwdriver (see Figure 8, page 12).
It is not permitted to use different operating modes in one loop/stub/T branch next to each other!
Address (A) Operating mode
0 0 0 Loop/stub in LSN improved version mode with automatic addressing
0 0 1 ... 2 5 4 Loop/stub/T branches in LSN improved version mode with manual addressing
CL 0 0 Loop/stub in LSN classic mode (address range: max. 127)
2 5 5 ... 2 9 9 Non-permitted address range (error message on fire panel)!
