Ultimate Water Leak Protection for Your Smart Home
Introducing the AJAX WaterStop, a smart, remotely controlled water shutoff valve designed to integrate seamlessly into your AJAX security system. This device provides peace of mind by automatically shutting off the water supply in as little as 5-7 seconds upon detecting a leak, preventing costly water damage. The WaterStop combines a high-quality Bonomi Industries valve with a powerful electric actuator, all controllable from anywhere in the world via the Ajax app. You can also set up automation scenarios to shut off the water at specific times or when you arm your security system.
Robust Design and Reliable Performance
The AJAX WaterStop is built to last, featuring a durable brass valve that is compatible with both hot and cold water pipes. Its powerful electric actuator delivers up to 8.5 N·m of torque, ensuring it can shut off the valve even if it's stuck. The device operates on pre-installed batteries with a life of up to 3 years, and also has the option for an external power supply. For manual control, there is a button on the actuator and a lever on the valve itself.
Advanced Wireless Technology
Utilizing AJAX's proprietary Jeweller radio communication technology, the WaterStop ensures secure and reliable two-way communication with the AJAX hub at a range of up to 1,100 meters in open space. This advanced protocol uses block encryption and frequency hopping to prevent sabotage, spoofing, and data theft, providing a robust and tamper-proof connection.
