Upon sensing moisture, Leak Controller will engage the shut-off valve and sound an alarm. The water source is cut off, stopping the leak while the alarm continues to sound until the valve is manually reset. By preventing continuous water flow, mold and property damage are restricted and user liability is reduced. Leak Controller is designed for simple installation and operation.Features:One Button system Testing/SilenceLeakLogic RISC Based Logic Control Valve to Tubing Connection Sizes:3/8" For Plastic and Copper TubingSensor Contacts Stainless Steel Plated2 Sensor MatsOne Sensor Included with Coin Test Slot and Series ConnectorsBuilt with Superior Impact resistant ABS PlasticBuilt With Superior Impact resistant ABS Plastic with Steered Components Reinforced with Nylon and Glass MaterialWater Detection Sensitivity Down to x ppm TDS (total dissolved solids)Conformal Coating on the Printed Circuit BoardSpecifications:Power: 4 "AA" size alkaline type batteriesSensor: Electromechanical dual probe with series connectors Temperature: System operating range: 40° F to 100° F Water operating range: 36° F to 140° F Size & Weight : 6.75" (H) 3.25 (W) 2.5 (D) .90 lbs. with batteries Solenoid: 6V DC Push-Type Alarm: 85+db at 5' @ 3.4 + 0.5 KHz pulsing alarm LED Operation: Flashing blue LED 4 times rapidly in succession repeatedly with audio Mounting: Accessories and bracket supplied for wall mounting Battery Replacement : Replace annually or upon low battery rapid LED flashing 4 times in succession w/ audio Warranty: 1 year limited warranty from date of purchase against defects in material and workmanship Great For:Filter SystemsReverse Osmosis SystemsIce MakersCoffee MachinesBeverage Machines LCS Installation Manual
