Water Leak Sensor


The WLS-15ZW is a Z-Wave water sensor designed to detect leaks/floods and to prevent water damage. It can be incorporated into any Z-Wave systems to deliver early warnings. During a water alarm, the WLS-15ZW generates a loud 95-decibel siren and flashes its red LED, providing effective audible and visual alerts to prompt a timely response. Its flexible deployment options allow for different residential and commercial applications. This lithium battery-powered sensor features more than 6 years of battery life.
