Feature:1. This is an exquisite water leakage alarm, using imported chips, stable work, high accuracy, and long service life.2. Adopts sound and light alarm, with switch valve LED indicator, 8 LED alarm indicator and 8 sensor interface.3. Place the sensor directly at the location where water may leak, once the water leaking is detected, it will trigger an audible and visual alarm, and the valve will be closed quickly.4. Commonly used in logistics warehouses, factories, hospitals, schools or homes and other situations.5. Mainly used to detect water leaks in water pipes, heating pipes, and central airconditioning pipes.Specification:Item Type: Water Leaking SensorCategory: AlarmAdapted Valve: DN15Power Supply Voltage: AC100-240VWorking Voltage: DC5VOutput Power: <5WSwitching Time: <5sWorking Pressure: <1MPaSwitching Times: 50000 timesMedium Temperature: 0-90Protection Level: IP65Trigger Alarm: 1sClose Valve: 1sHost Front 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 Transformer interface, valve interface, 1-8 sensor interfaceHow to Use:1. Install the valve on the pipeline2. Hang the main unit of the water leakage alarm in a suitable position to avoid wet environment and direct contact with water3. Place the sensor in a place where water may leak (pay attention to avoid direct contact of the sensor contacts with metal objects)4. Insert the transformer, valve and sensor into the corresponding position of the host5. Plug the transformer into the power socket, power on the host, and start the water leakage alarm for self-checking. The valve defaults to the closed state. Manually press the valve open button, the valve opens automatically, and the water leakage alarm enters the working state6. When the water leakage alarm detects water leakage, it will immediately sound and light alarm and quickly close the valve. The alarm will continue to sound and light alarm. After the water leakage point is manually removed and the water is cleaned, you need to manually press the reset button to release the alarm, and then manually press the valve opening button, the valve opens, and the alarm continues to enter the working state..Package List:2 x Valve1 x Host Control Box2 x Sensing Cable1 x Adapter1 x User ManualNote:1.
