THE DUAL TANK ALARM has two adjustable float switch alarm points. If either point is activated by high or low liquid level, an piercing alarm sounds and flashing LED activates. Float switches can monitor high or low level. Different alarm pattern for each float. (rapid or slow flashing and beeping)
Easily adjust able depth with no tools - just loosen the thumbscrew and slide either level probe to the desired depth. 12 inches of depth adjustment.
When liquid level activates the float, the LED flashes and buzzer sounds. The buzzer can be silenced by pressing the pushbutton while the LED continues to flash until the liquid level is corrected. Snooze alarm every 30 minutes until the level is corrected. Resets automatically when level is corrected.
Power save feature limits the alarming to 60 minutes of full output, and if the alarm is ignored, then the alarm output is reduced to 6 seconds every 30 minutes. This allows a single battery to alarm continuously for weeks!
