The alarm has consistently held up in the excessive cold and heat due to the high-quality sensor.No False Alarmsdue to new boat smell, outgassing, or non-hazardous levels of hydrocarbon gases encountered while boating. Interconnect and generator shut-off alarms are available.Low Current Draw(37 mA). An innovative micro-current circuit saves battery power for the boater.Alarm Mute with Auto Reset.With a press of a button, the mute circuit will temporarily silence the alarm while the boater ventilates the cabin.
