Wireless water leak detectors and shutoff valves

Ajax wireless water leak detectors can prevent flooding from the first drops. As soon as water seeps onto one of the four pairs of sensors, the system instantly activates an alarm. Notifications about flood are transmitted to users and a security company. And WaterStop can automatically shut off the water until emergency services arrive.

Features of Ajax automated water leak detection system

Minimum hassle

Ajax water leak detectors operate from batteries that need to be replaced every few years. No tools are required to install the detector. It is enough to put it in the place of a possible leak: for instance, under a sink or bathtub. The detector is resistant to dust and moisture, and the miniature housing allows placing it in a hard-to-reach place.

Maximum protection

If the leak is insignificant or water seeped onto contact accidentally, the detector reports drying as quickly as leakage. In real problems, the detector can run a scenario of automatic water shut off, and there is no need to rush to the facility because of the alarm.

Automatic water shutoff

WaterStop remotely shuts off the water supply at the secured by Ajax facility. The device consists of a Bonomi shutoff valve and a powerful electric actuator with a control unit. WaterStop connects to the hub using the secure Jeweller radio protocol. With an internet connection, you can control the water shutoff valve from anywhere — Ajax apps allow you to check the device status and change the valve position remotely at any time.

WaterStop will automatically shut off the water in 5 seconds by LeaksProtect alarm. At the same time, all users, and the security company will receive a notification about the leak alarm and scenario activation. Water shutoff can also be configured by schedule or when the security mode changes.
