Fireboy-Xintex Propane Fume Detector w/Plastic Sensor & Solenoid Valve - Black Bezel Display

The Fireboy-Xintex Propane Fume Detector with Plastic Sensor and Solenoid Valve is a dedicated propane leak detection and automated shutoff system designed for vessels, RVs, and enclosed spaces where propane safety is mission-critical. This black bezel display unit combines early-stage gas detection with automatic valve closure to prevent dangerous accumulation and potential explosions before they occur.

The detector activates an audible alarm (68 dBA) and illuminates a red LED indicator when propane concentration reaches 20% of the Lower Explosive Limit (LEL)—well before dangerous levels accumulate. The integrated solenoid valve automatically closes the gas supply upon detection, cutting off the fuel source without requiring manual intervention. The 2-3/16-inch round display features front-mounted controls including a Silence/Test button for system diagnostics and a dedicated solenoid valve control button for manual operation. The plastic sensor element is suited for standard marine and recreational vehicle installations, while the included solenoid valve adapter enables straightforward integration into existing propane lines.

This system is essential for liveaboards, offshore fishermen, RV operators, and anyone relying on propane in confined spaces where gas accumulation poses serious risk. Early detection at 20% LEL provides a safety margin that allows crew or occupants to respond, ventilate, and address the source before explosive concentrations develop. The automatic solenoid closure removes the variable of human reaction time during emergencies, making it a passive safety layer independent of operator awareness.

Propane detection standards in marine environments and recreational vehicle safety codes increasingly mandate or recommend systems like this. The Fireboy-Xintex platform is recognized in marine and RV markets as a reliable choice for meeting insurance and regulatory expectations while providing transparent, verifiable protection against one of the most dangerous hazards in confined vessel and vehicle spaces.
