Maretron CO-CO1224T Co Sensor

The Maretron CO-CO1224T Carbon Monoxide Detector is a marine-grade safety system designed to protect crews and passengers aboard vessels from the silent threat of carbon monoxide accumulation. Carbon monoxide buildup in enclosed cabins, engine compartments, and generator spaces poses a serious health risk, particularly in boats where diesel engines and enclosed spaces create dangerous concentrations. This system-monitored detector provides continuous real-time monitoring with dual alarm stages, ensuring early warning before dangerous levels develop.

Built to UL standard 2075 specifications, the Maretron CO-CO1224T operates as a 4-wire networked sensor within larger marine monitoring systems, offering both a local sounder alarm and relay-based outputs for integrated bridge displays and automation. The detector features a dual LED indicator system to distinguish between normal operation and alarm conditions, while Form C alarm and Form A trouble relays enable automated shutdown of ventilation systems or engine ignition sources when thresholds are exceeded. Low current draw makes the unit ideal for battery-powered vessels, drawing minimal power while maintaining constant vigilance over cabin air quality.

This detector benefits cruising sailors, liveaboards, and commercial vessel operators who depend on reliable early warning systems to prevent carbon monoxide poisoning in sleeping quarters and galley spaces. Installation is straightforward in vessels already equipped with Maretron N2K (NMEA 2000) network infrastructure, though the standalone sounder function allows emergency alerting even during network failures. Whether upgrading aging mechanical detectors or building a comprehensive marine safety system from scratch, the CO-CO1224T delivers certified protection with network integration that modern boating demands.
