The FPCF20 is a dedicated diesel engine fire pump controller from Zhejiang Yonjou Technology, delivered fully configured from the factory with dual-battery management and all engine wiring pre-integrated. It is designed to meet NFPA20 requirements for fire pump service, providing reliable automatic starting of diesel-driven fire pumps in commercial, industrial, and municipal fire protection installations.

How does the FPCF20 start the fire pump automatically?

The controller monitors pipeline pressure continuously and initiates an automatic engine start when pressure drops below the setpoint, indicating water flow from an open sprinkler or standpipe. Additional start triggers include a remote contact closure, a dedicated fire alarm input, and an automatic drain valve signal. A built-in periodic auto-inspection routine starts the engine on a programmable schedule to verify readiness without manual intervention.

What battery management features are included?

The FPCF20 maintains two independent batteries with continuous float charging driven by battery voltage sensing. An intelligent switching system automatically selects the healthier battery for cranking and switches to the backup if the primary battery voltage is insufficient. Battery health indicators on the front panel provide at-a-glance status for both batteries plus AC and DC power health.

What alarms and protections does the controller provide?

The controller includes an engine intelligent protection system that monitors critical engine parameters and triggers a system error alarm if faults are detected. An alarm mute function silences audible alerts while maintaining visual indication. The front panel features individual LED indicators for system error, AC power, DC power, fire alarm, dual-battery health, automatic mode, and heater status. An emergency stop mushroom button provides immediate manual shutdown.
