In an effort to combat the devastation of water damage in the home, Yale has launched a smart water sensor that will alert homeowners if their home is in danger of flooding. The design of the Sync Water Sensor accessory is simple and effective featuring two external metal sensing contacts, when both strips get wet, through a plumbing leak, flood, or surrounding moisture condensing on the surface, the alarm will sound through the Yale Sync Smart Home Alarm or Yale Intruder alarm (depending on which system you have). At the same time, the device will send an alert to your smart device* to warn of the presence of water. The detector is not a one-time use device. Each time the sensing contacts make contact with moisture and the alarm sounds, simply dry the contacts. Return the detector to its location or choose a new location as needed. Features: Activates the alarm if a leak is detected, and send through either a push notification or ring your phone to keep you informed.* (SYNC alarm only) Ideal for placement behind washing machines and under sinks 200m wireless range Built in tamper protection Secure encryption Battery Included About this item SYNC ALARM ACCESSORY: This Water Leak Sensor is easy to pair with your Yale Sync Smart Home Alarm through the Yale Alarm App. SYNC WATER LEAK SENSOR: Will trigger your alarm and enable the Sync Smart Home Alarm to notify you immediately.
