Feature:1. This is a small water leaking alarm, which is mainly used to detect water leaks in water pipes, heating pipes, and central air‑conditioning pipes.2. Install the sensor in a location where water may leak, if a water leaking is detected, an audible and visual alarm will be triggered, and the valve will be closed quickly.3. The sensor uses imported high‑sensitivity chips, stable operation, high accuracy and long service life.4. Adopt sound and light alarm, with switch valve LED indicator, 8 LED alarm indicator and 8 sensor interface, standard electric ball valve.5. Used in a variety of sotuations where water leaking, such as logistics warehouses, factories, hospitals, schools or homes.Specification:Item Type: Water Leaking SensorCategory: AlarmAdapted Valve: DN15Output Power: <5WSwitching Time: <5sWorking Pressure: <1MPaSwitching Times: 50000 timesMedium Temperature: 0-90℃Protection Level: IP65Trigger Alarm: 1sClose Valve: 1sHost Front Description: First Row: Power indicator light, valve open indicator light, valve close indicator lightSecond Row: Reset button, valve open button, valve close buttonThird Row: 1-8 Road Alarm Indicator Lights: Host Side Description: Transformer interface, valve interface, 1-8 sensor interfaceHow to Use:1.
