Overview

Ajax WaterStop automatically shuts off the water in 7 seconds at a facility with an Ajax security system if LeaksProtect or a third-party water leak detector is triggered. The device combines a high-quality valve and a powerful electric actuator. You can control Ajax WaterStop and check its status from anywhere in the world — all you need is an Internet connection and an Ajax app. You can also create a scenario to shut the water off at a specific time or when arming the system.
