These DC powered low voltage carbon monoxide detectors are often used with alarm and security systems, building control systems or in mobile homes and RVs. They typically run on 12VDC or 24VDC and most models have built in relay outputs for connection to a security alarm system, fan control system or building control system.
Carbon Monoxide detectors are used to detect deadly CO gases produced by incomplete combustion or from vehicles, forklifts and the like.
