Battery Backup:

Internal wires provided to attach your 12 volt chargeable backup battery. If power is lost and an alarm condition occurs the alarm will sound. The alarm draws 10 ma. The wall mounted power supply will keep your external backup battery charged. We recommend a motorcycle style lead acid or AGM battery.

How it works:

The alarm has a float on a line cord. On the line cord there is an adjustable weight. The weight slides on the cord and is placed in the well at the level you want the alarm to sound. The float switch is hanging below the weight. When the liquid rises to the level of the weight the float switch activates the alarm. This indicates that the liquid has reached an alarm point indicating pump failure.
