Relay Interface Modules Low Voltage
FLM‑420‑RLV1-E -
The FLM‑420/4‑CON-D Conventional Interface Modules allow conventional detectors to be connected to LSN fire panels via a 4‑wire supply network (Local SecurityNetwork LSN with external power supply).
The interface modules in the 420 series have been specially developed for connecting to the Local SecurityNetwork LSN improved version and offer the enhanced functionality.
The detector lines are short-circuit proof. In the event of a short circuit on the line, a fault message is sent to the control panel.
