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. 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. The low profile, softly curved shape eliminates the chance of being broken off the wall in confined spaces. 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. Assembled with state of the art, robotic automation to produce consistently high quality and reliability.
