The RV Safe alarm is unsurpassed in its use of the latest technology to quickly and accurately alert occupants of the presence of deadly Carbon Monoxide and Propane Gas. Alerts users to hazardous levels of Carbon Monoxide and Propane gas. Uses the latest in advanced electrochemical CO sensors to detect carbon monoxide. Fewer false alarms from non-threatening chemicals and gases due to our highly selective carbon monoxide sensor. Increased RV battery life compared to competitor’s alarms due to our unique low power gas detection circuitry. Test/Silence button allows for easy testing of the alarm and quickly silence nuisance alarms. Compact design enables installation almost anywhere on the walls and cabinets. Simple to install with only a 3/4 inch hole required for the wires and two flat head self tapping screws. No sawing or routers required. Available in both two (standard) and three wire configurations to allow for connection to a secondary battery source. Alarm activates with a four beep pattern with a flashing red LED for CO gas, or a continuous beeping with a solid red LED for Propane gas. If both gases are present, the alarm will indicate Propane as it requires more immediate action. Meets or exceeds all UL2034 requirements for Carbon Monoxide alarms in Recreational Vehicles.
