Fireboy-Xintex Engine Shutdown - 5 Circuit w/20A Relays - Round Display

The Fireboy-Xintex Engine Shutdown - 5 Circuit with 20A Relays - Round Display is a critical marine safety system designed for diesel-powered vessels operating in high-risk environments. In maritime and naval operations, rapid engine shutdown during an onboard fire is non-negotiable—continued engine operation can feed flames, spread fuel, and compromise suppression system effectiveness. This five-circuit engine shutdown system enables crew to remotely isolate multiple engine systems simultaneously, preventing catastrophic fuel flow and airflow that would sustain a fire during active suppression discharge.

The system features five independent circuits with heavy-duty 20-ampere relays, providing redundant shutdown capability across fuel injection, ignition, air intake, and auxiliary engine systems. The round display interface delivers clear, intuitive circuit status and manual override control in high-stress conditions when split-second decisions matter. Built to USCG and SOLAS marine standards, the relay architecture ensures reliable actuation even under extreme vibration, saltwater corrosion, and electrical noise common to maritime diesel engines. Each relay is rated for continuous duty and designed to isolate systems cleanly, preventing cross-circuit faults that could hamper emergency response.

Law enforcement marine units, Coast Guard vessels, military patrol boats, and commercial fishing operations depend on this shutdown system to meet regulatory compliance and crew safety mandates. The compact 6 x 5 x 12-inch profile integrates easily into existing wheelhouse console layouts without sacrificing accessibility during emergency situations. Installation requires 12/24-volt DC auxiliary power and hardwired connections to engine fuel, ignition, and air systems—professional marine electrician installation is strongly recommended to ensure proper relay calibration and system integration with your specific diesel engine configuration.
