Propane Monitors With or Without Propane Tank Shut-Offs Safe-T-Alert offers an important RV accessory: a propane gas detector or propane gas alarm with or without a propane tank shut off valve. Replace CCI Controls' propane alarms with CO detectors such as the Safe-T-Alert Propane Carbon Monoxide Gas Alarm with Relay and Automatic Propane Shut-Off Valve and protect your life! Safe Home Products® also sells dual propane and carbon monoxide detectors like the 70-742 gas and CO detector test/reset buttons and mute alarm settings. If you want a 2-in-1 product without the relay, choose the smaller combination LP and CO Alarm for recreational vehicles (RV). Or choose the 70-742 series combination units. Choose Safe Home® to protect your RV or trailer from combustible gas leaks. |
