NOTICE!
Installation must only be performed by authorized and specialized personnel!
CAUTION!
Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.
DANGER!
Live components and stripped cable! Risk of injury from electric shock.
The system must be current-free during connection work.
Functional description
FLM-420-NAC Signaling Device Interface Modules make it possible to connect
sounder, strobes, and horns to LSN fire panels. Each interface offers one
monitored primary line. The control of the signaling device line
(NAC=Notification Appliance Circuit) is performed through polarity reversal.
Interface module variants:
- FLM-420-NAC-S for surface-mounting with housing (see Figure 2 to Figure 6, Page 5 to Page 8).
- FLM-420-NAC-D for installation on a DIN rail with adapter (see Figure 7 and Figure 8, Page 9 to 10).
Address setting
Fit a rotary switch in the required position using a pan head slotted screwdriver (see Figure 1, Page 4).
| Address (A) | Operating mode |
|---|---|
| 0 0 0 | Loop/stub in LSN improved version mode with automatic addressing (T-tap |
system not possible)
0 0 1 — 2 5 4| Loop/stub/T-tap system in LSN improved version mode with manual
addressing
CL 0 0| Loop/stub in LSN classic mode
2 5 5 — 2 9 9| Non-permitted address range (error message on fire panel)!
