Carbon monoxide (CO) detector

Carbon monoxide (CO) is a toxic, invisible, odorless, and tasteless gas produced by incomplete combustion of fuels (engines, generators, heaters). On a boat, it can accumulate rapidly in enclosed spaces and cause severe or fatal poisoning. A CO detector is a fundamental safety measure to prevent these risks by alerting occupants before concentrations become dangerous.

The CO-CO1224T is designed for installation on an NMEA 2000 network. It transmits alarm and status information to the network so that it can be used by compatible equipment in the installation.

The datasheet specifies a 12 V DC power supply. Before installation, verify the available onboard power circuit, electrical protection, and the Raymarine/Maretron manual recommendations.

No, the technical data indicate an indoor installation environment. It must be mounted in a protected area suitable for carbon monoxide detection and compliant with the manufacturer's installation instructions.

CO detectors should be installed in areas where occupants sleep or spend the most time, as well as near potential CO sources. This typically includes:

Sleeping cabins.The saloon or bridge.Near engines, generators, or heating systems, while maintaining a safe distance to avoid false alarms from non-toxic fumes.Always consult the installation manual for the manufacturer's specific recommendations.

Areas for living and sleeping, as well as spaces exposed to exhaust gases, should be prioritized. The exact location must comply with the installation manual and account for actual air circulation onboard.

No. A CO detector is an alert device, not a ventilation solution. Engines, heaters, and combustion appliances must remain properly installed, maintained, and ventilated.

Yes, in a suitable NMEA 2000 architecture, the detector can be paired with compatible alert devices, for example a siren or a network alarm. Exact compatibility depends on the installation and equipment configuration.

The CO-CO1224T monitors carbon monoxide, a toxic, invisible and odourless gas. A smoke or heat detector addresses a different hazard. On a liveaboard sailboat, these protections are complementary.

Yes. The technical specs indicate NMEA 2000 compatibility and an NMEA 2000 data output, making it suitable for network integration rather than a standalone standalone sensor.

Yes. Like any safety equipment, it must be tested and inspected periodically according to the manufacturer's procedure. The condition of the wiring, power supply, and NMEA 2000 network must also be checked.

It is suitable for liveaboards, enclosed cabins or berths, and installations with engines, generators, heaters or other potential combustion sources.
