Maretron High-Temperature Smoke/Heat Detector Kit – SH-003

The Maretron High-Temperature Smoke/Heat Detector Kit (SH-003) is a rugged, marine-ready safety system designed to detect rapid temperature rises or smoke in high-heat environments like engine rooms and machinery spaces. When integrated with your NMEA 2000® network via a Maretron SIM100 Switch Indicator Module (sold separately), this kit enhances vessel safety by providing real-time alarm status that can be displayed on networked screens and interfaces. 

Built to withstand marine conditions, this kit includes an advanced multi-sensor detector, a sounder, and an auxiliary relay — all rated for high temperature operation. Its components are engineered to remain functional in environments ranging from sub-freezing to extreme heat commonly found around engine spaces, ensuring reliable detection when it matters most.

Summary for the User

The SH-003 is a professional-grade safety upgrade. While a standard home smoke detector might melt or fail in a hot engine room, this kit is built to withstand those conditions. To get the most out of it, you should link it to your NMEA 2000 backbone so you can receive alerts even if you are at the helm with the engine room doors closed.

Installation Tip: For maximum safety, mount the detector on the ceiling as close to the center of the engine room as possible, avoiding areas near ventilation fans that might blow smoke away from the sensor.
