Safety Notes
Functional description
The FLM-420-RLV8-S Octo-relay Interface Module Low Voltage has eight change-over contact relays to provide a
potential free output contact.
The programming is carried out via the programming software of the fire panel.
Cables are fed through rubber bushings or PG cable glands (see Figure 3, Page 5).
The pluggable terminal blocks of the interface module allow for an easy wiring (even if built in).
Address setting
Fit a rotary switch in the required position using a pan head slotted screwdriver (see Figure 4, Page 6).
Connection
See Figure 6, Page 7.
