Air Flow Alarm

  • The battery-powered air flow alarm monitors the operation of a radon sump system to give you peace of mind. 

    Mounted directly onto the system's exhaust pipework, the alarm alerts users of low or no air flow conditions. This could happen if the fan fails, the power supply is cut or if the sump or pipework is blocked.

    An audible buzzer alternates with a flashing LED light when the system is not operating properly.

    Please note that this alarm does not monitor radon levels
