## Overview

This 12V DC wired water leak detector features an 80dB buzzer and a powerful 10A NC/NO relay output to instantly alert and control connected devices like shut-off valves. With adjustable sensitivity and rust-proof probes, it offers reliable, precise flood detection for home or commercial security systems, ensuring rapid response to water leaks and preventing costly damage.

## Description

Description:The Water detector is part of the security system. Itindicates whether the sensor is dry or completely immersed in water by measuring conductivity. When the electrode detect the water, two rust-proof metal probe meet the water, the circuit isOn-state, And the controller relay will activate with N.C orN.O signal, and also it can control any other device(Max.10A 250VAC or 10A30VDC).Sensor:metal probeSensitivity: Anticlockwise - Clockwise +Voltage:DC10 to 15VCurrent:Static:≤10uA; Alarm:≤40mAPower Indicator:Green LED OnAlarm:Red LED On and Relay ActivateAlarm Output: Relay N.C or N.O(Max.

Review: Works like it should. - Works like it should.
Review: Water cooler shut off. - We bought this because we have a water cooler that occasionally leaks if the pump gets stuck on. The water cooler sits on a mat in the barn and we have the sensor sitting down on the mat. If the pump stays on and leaks, the sensor reads it and the relay kicks on and turns off the system. I have a 12 volt power supply separate from the cooler to power this up. Pretty slick switch for $20.

## Questions & Answers

**Q: Not able to adjust the sensitivity, the alarm is always on. Any recommendations.**
A: Yes I had the same problem. However as a electronic
Tech. I could make a a slight change in the circuit to 
Rectify that. However I could not submit the cure 
For other than personal use. 
Call the company that made it. They might just replace it.

**Q: Can this be wired to turn on a bildge pump instead of the siren?**
A: In a bilge application and underway, you would need two of these to trigger the pump to turn on and off when the water has not gotten deep enough to require the bilge pump to turn on.  I would put one low enough so that it stays submerged, signal lost if uncovered by water. Then when the higher sensor detected water a latching relay that is tripped would keep the pump running, use another relay for the pump, and when the lower sensor becomes uncovered the pump shuts off.  You need two of the devices, you can have more than one sensor, I have 6 on each devices monitoring area.

**Q: Using on a bilge pump. issue is once the bilge was pumped out any slight amount of water kicks the pump on and immediately off. do i need delay relay?**
A: Use a back flow preventer in the pump output hose to keep water returning to the bilge which then restarts the pump after the pumps first shuts off.

**Q: Will this detect cat urine?  Cat will pee along a certain wall, want to hide 2 wires in the carpet edge, alarm scares cat and alert me**
A: I would think that it would, I am using it for detecting spills in water stores that refill 5 gallon cooler bottles, and it works perfectly on the city water, however the Permeate, low TDS water has to have a really large contact area to trip the sensor.  The long wires version should work the best.  I even had to add some salt crystals near the sensor to get the product water to become conductive enough.  My recommendation is to buy it, use your wires to try it, if it doesn't work return it becuase you did not use their sensors.  Strip your wires and place them near each other and cover the whole length where the pee pools on the floor you need the liquid to conduct the signal.
