Relay Interface Modules Low Voltage Relay Interface Modules Low Voltage
The FLM‑420‑RLV1-D Relay Interface Modules Low Voltage feature a changeover contact relay for providing a potential-free output contact. The interface modules used for the activation of fire protection equipment and whose outputs are not monitored, must be installed directly next to or within the device which shall be activated.
They are 2‑wire LSN elements. When connected to the fire panels FPA‑5000 and FPA‑1200, the interface module offers the enhanced functionality of LSN improved technology
