This fan failure alarm lets you know if your radon fan has failed or if one of your pipes is blocked with ice.  The alarm sounds when a loss of exhaust flow is detected.  The secondary gauge port allows the installer to measure actual system exhaust pressure.  The large, bright lights on the alarm are easily visible. This fan failure alarm can be easily mounted to a flat surface or PVC piping.

This fan failure alarm is perfect for remotely located systems that you cannot get to in order to inspect them regularly. 

This fan alarm is compatible with all Active Sub-Slab Depressurization (ASD) systems.
