Tank Alert® AB DUO

Indoor Tank Alarm Monitors 2 Levels in 1 Convenient Alarm

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

The Tank Alert® AB DUO (Auto reset, Battery backup, DUO alarm inputs) indoor alarm system monitors two liquid level conditions in one easy-to-install alarm for lift pump chambers, sump pump basins, holding tanks, sewage, agricultural, filter and other waste applications.

The sleek design of the alarm features a user friendly touch pad with colored LED indicators for easy visual detection.  The alarm horn and red LED indicator activate for a high level alarm condition.  The alarm horn and yellow LED indicator activate for alarm 2.  The green LED indicates 120V primary power to the alarm.  Once the condition is cleared, the alarm automatically resets.
