Wisualarm DHI-HY-WL13A-R8 Wireless Water Leak Detector

Water leaks can cause extensive damage before you even notice them—warped floors, ruined furniture, and costly repairs. The Wisualarm DHI-HY-WL13A-R8 Wireless Water Leak Detector provides an early warning system that alerts you the moment water touches its sensor, giving you time to act before a small leak becomes a disaster.

Who is it for

This detector is ideal for homeowners, landlords, and facility managers who want to protect properties from water damage. It is especially useful in areas prone to leaks, such as under sinks, near water heaters, washing machines, dishwashers, and in basements or utility rooms.

Tips

Place the detector on the floor or mount it on a surface where leaks are likely to occur, such as near the base of a water heater or under a sink. Test the detector regularly by touching the sensor probes with a damp cloth. Replace the CR2032 battery when the low battery indicator activates or at least every three years. For best wireless performance, ensure the detector is within range of your Dahua Airfly alarm panel and avoid placing it inside metal enclosures.
