Tank Alert® EZ

Indoor/Outdoor Alarm with Removable Cover for Easy Installations

Tank Alert® alarms provide audio/visual warning of potential threatening liquid level conditions.

The patented Tank Alert® EZ alarm is all about making installations easier!  This indoor/outdoor alarm offers significant improvements over other alarms currently available for lift pump chambers, sump pump basins, holding tanks, sewage, agricultural and other waste applications.



The Tank Alert® EZ easy-to-install alarm features an innovative, sleek 2-color molded enclosure which integrates the LED red translucent beacon; the upper half illuminates and horn sounds when an alarm condition occurs.  Once the condition is cleared, the alarm automatically resets.   

The Tank Alert® EZ alarm features external mounting tabs for quick, easy installation.  The removable cover allows greater access for easier field wiring.  Standard features include an alarm test/silence switch, green power on indicator, and auxiliary contacts for remote devices.
