The AquaGate CX Leak Controller is a specialized, affordable water alarm and shut-off system. Battery operated and features a 1" full-port electric ball valve shut-off. Upon sensing moisture, AquaGate CX will engage the shut-off valve and sound an alarm. The water source is cut off, stopping the leak while the alarm continues to signal until the unit is reset. Up to 4 sensors can be directly connected to the control panel. Unlimited sensors may be "daisy-chained" together for increased coverage and protection in multiple areas.
