Line monitoring when operating with EOL resistor
Contact monitoring
Voltage monitoring
Individual monitoring of the two inputs
Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators
The FLM‑420‑RHV Relay High Voltage Interface Modules
are used to control the activation of external elements,
e. g. smoke dampers or fans (FAN function), via the Local
SecurityNetwork LSN.
