Protect your property with this advanced Water Leakage Alarm system, designed for high accuracy and stable performance using imported chips. Featuring both sound and light alarms, this device offers immediate and clear alerts through 8 LED alarm indicators and supports up to 8 sensor interfaces for comprehensive water leak detection. Equipped with a standard DN20 electric ball valve, it integrates seamlessly with existing water pipe systems to provide automatic shutoff within seconds of detecting a leak, minimizing potential water damage. Key Features: · High-Precision Leak Detection: Utilizes imported chips to ensure accurate and reliable water leakage sensing, reducing false alarms and enhancing safety. · Audible and Visual Alarm: Equipped with sound and light alarms, including 8 LED indicators, to promptly notify you of any water leakage. · Fast Valve Response: The DN20 electric ball valve closes automatically within 1 second after leak detection, effectively stopping water flow and preventing further damage. · Durable and Versatile Design: Suitable for various environments such as logistics warehouses, factories, hospitals, schools, and residential homes. · Multiple Sensor Interfaces: Supports up to 8 sensor connections, allowing flexible placement of sensors in critical areas prone to water leaks. · User-Friendly Controls: Features power, valve open/close indicators, reset button, and valve control buttons for easy operation and maintenance. · Robust Construction: IP65 protection level ensures resistance to dust and water ingress, suitable for challenging environments. · Long Service Life: Electric valve rated for up to 50,000 switching cycles, ensuring reliable long-term operation. Specifications: · Item Type: Alarm Sensor · Category: Alarm · Adapted Valve: DN20 Electric Ball Valve · Output Power: <5W · Switching Time: <5 seconds · Working Pressure: <1MPa · Switching Times: 50,000 times · Medium Temperature Range: 0-90℃ · Protection Level: IP65 · Alarm Trigger Time: 1 second · Valve Close Time: 1 second Package Includes: · 1 x Water Leakage Alarm Host Unit · 1 x DN20 Electric Ball Valve · Sensor Interfaces for up to 8 sensors Installation and Usage: Install the DN20 valve on the water pipeline and mount the main alarm unit in a dry, safe location away from direct water exposure. Place sensors at potential leak points, ensuring sensor contacts do not touch metal objects. Connect the transformer, valve, and sensors to the corresponding interfaces on the host unit. Upon detecting water leakage, the system will immediately trigger audible and visual alarms and close the valve to prevent flooding. After resolving the leak, manually reset the alarm and reopen the valve using the control buttons to resume normal operation. This Water Leakage Alarm system offers a reliable and efficient solution for early leak detection and automatic water shutoff, providing peace of mind and protection for your property and valuable assets.
