This Safe-T-Alert Combo Alarm in black is a surface-mount detector for propane and carbon monoxide. It handles both gases at once, replacing two separate alarms. Power comes from the 12 volt system rather than a battery.
Safe-T-Alert builds it to hold up in the demanding RV environment. It meets RVIA and NFPA requirements. An end-of-life signal warns when the sensor is due for replacement.
Safe-T-Alert recommends testing propane and CO alarms every week, replacing any that malfunction, and replacing all alarms 5 years old or older. The surface-mount housing installs without cutting a wall opening. Confirm rail fit, ring diameter and available clearance together, especially when the optic has a large objective bell.
