Maretron

<h3>Maretron: The Standard in Intelligent Vessel Monitoring</h3><p><strong>Maretron</strong> has been at the forefront of networked marine electronics since its founding in 2003. Built on the open <strong>NMEA 2000&reg;</strong> standard, Maretron&apos;s ecosystem of sensors, displays, software, and networking hardware gives mariners a unified, real-time view of every critical system aboard — from engines and fuel tanks to electrical circuits, weather, and navigation data. Whether you run a weekend sailboat or a long-range passagemaker, Maretron&apos;s modular platform scales to meet the demands of virtually any vessel.</p><h3>A Complete Ecosystem, Not Just Individual Products</h3><p>What sets Maretron apart is the depth and breadth of its product lineup. At the heart of the system is the N2KView&reg; vessel monitoring software, which aggregates data from hundreds of NMEA 2000 data points into a single customizable interface. Paired with real-time cloud services, N2KView&reg; allows operators to monitor their vessel remotely — whether dockside or from shore — with configurable SMS and email alerts for out-of-range conditions.</p><p>The hardware side of the Maretron portfolio is equally comprehensive. <a href="/200363-electronics-parts-accessories-maretron-11272">Electronics parts and accessories</a> form the backbone of any Maretron installation, including NMEA 2000 gateways, sensor modules, run indicator modules, switch interfaces, and the cabling infrastructure that ties it all together. Maretron is recognized as the first company to offer NMEA 2000-approved cabling, a distinction that underscores their deep commitment to the standard.</p><h3>Power Monitoring and Electrical Intelligence</h3><p>Keeping tabs on onboard power is critical for any mariner, and Maretron&apos;s <a href="/11272-maretron-battery-monitors-volt-meters-200146">battery monitors and volt meters</a> deliver precise, actionable data. The DCM100 Direct Current Monitor and OctoPlex&reg; Battery Monitor measure current draw, DC voltages, and battery temperatures, broadcasting all readings over the NMEA 2000 network so they can be displayed, logged, and alarmed alongside every other vessel system.</p><h3>Displays That Bring Your Vessel to Life</h3><p>Data is only useful if you can read it clearly. Maretron&apos;s <a href="/200956-multi-function-display-systems-maretron-11272">multi-function display systems</a> — including the DSM250 sunlight-readable color display and the TSM810C vessel monitoring touchscreen — present NMEA 2000 data through intuitive, customizable screen layouts. These displays are designed specifically for the marine environment, with rugged housings tested to IEC 60945 standards to withstand saltwater, vibration, and heavy-weather use.</p><h3>Navigation and Positioning</h3><p>Accurate positioning is fundamental to safe seamanship. Maretron&apos;s <a href="/200497-gps-cellular-wifi-antennas-maretron-11272">GPS antennas</a>, exemplified by the GPS200 GPS Antenna/Receiver, deliver reliable position fixes, boat speed, and precision timing directly onto the NMEA 2000 network. Because the data is broadcast over the shared network bus, any compatible display or software on board can instantly access GPS information without point-to-point wiring.</p><h3>The Network That Holds It All Together</h3><p>No NMEA 2000 network is complete without quality interconnect hardware. Maretron&apos;s <a href="/200987-specialty-connectors-maretron-11272">specialty connectors</a> — including T-connectors, terminators, and backbone cables in Micro and Mid configurations — are engineered to the same rugged waterproof standards as every other component in their lineup. Using properly rated connectors is especially important in the marine environment, where a single corroded contact can disrupt an entire network.</p><h3>Now Part of the Raymarine Family</h3><p>Maretron&apos;s vessel monitoring product lines — along with MPower&reg; digital switching and OctoPlex&reg; power distribution — are now part of the Raymarine family of brands, ensuring continued development, support, and integration with a broad range of chartplotters and marine electronics systems. For mariners who demand a complete, integrated picture of their vessel&apos;s health, Maretron remains the definitive choice.</p>

Product Details

Maretron's High-Temperature Smoke/Heat Detector Kit is an intelligent NMEA 2000® networked solution designed to alert you of unusually fast temperature rises or the presence of smoke in demanding marine environments. This comprehensive safety system is specifically engineered for high-temperature areas such as engine rooms, machinery spaces, and other critical zones where standard smoke detectors cannot operate reliably.

What's Included:

  • High-temperature smoke and heat detector
  • Auxiliary relay module
  • Audible sounder alarm

Key Features:

  • Wide operating temperature range from -25°C (-13°F) to +70°C (158°F)
  • NMEA 2000® network integration via Maretron SIM100 Switch Indicator Module (sold separately)
  • Dual detection: responds to both rapid temperature rise and smoke presence
  • 24 VDC power supply operation
  • Marine-grade construction for harsh environments
  • Network-based alerts allow remote monitoring from navigation displays

The SH-003 provides critical early warning protection in areas where conventional smoke detectors would fail due to elevated ambient temperatures. When connected to your vessel's NMEA 2000® network through the SIM100 module, the system can trigger visual and audible alarms throughout the boat, ensuring crew awareness regardless of location.
