Product Description

Metron FD4-MB301 is the Main Board (MB) of FD4 series diesel engine fire pump controller manufactured by Metron Eledyne (USA). It serves as the core processor board inside fire pump control cabinet and fully complies with NFPA20 and UL218 fire standards. This mainboard executes automatic start-stop logic for diesel fire pumps, water pressure measurement, engine status monitoring, fault protection, event and pressure data logging, and communicates with external OID operator interface device. It is equipped with on-board SD card slot for recording over 3000 event logs and continuous pressure history. It supports automatic cyclic cranking and adjustable sequential start delay for multi-pump systems, widely used as spare part for diesel fire pump control cabinets in buildings, power plants and offshore platforms.
