Total Control Over Your Water Supply, Instantly.
Protect your property from the devastating effects of water damage with the AJAX WaterStop, a smart, wireless water shutoff valve. Integrated into your AJAX security system, the WaterStop gives you the power to shut off your water supply remotely from anywhere in the world using the Ajax app. In the event of a leak detected by an AJAX LeaksProtect sensor, the WaterStop can react automatically in as little as 5 seconds, minimizing potential damage and giving you ultimate peace of mind.
Key Features:
- Rapid Emergency Shutoff: The powerful electric actuator can shut off the water flow in just 5-7 seconds, whether commanded manually or triggered by an automated scenario.
- Powerful & Reliable: With a torque of up to 8.5 N·m, the WaterStop can turn even a stuck valve, ensuring reliable operation when you need it most.
- Remote & Automated Control: Use the Ajax app to check the status and control the valve from anywhere. Create scenarios that automatically shut off the water when a LeaksProtect sensor or a third-party detector is triggered.
- Long-Range & Secure Communication: Featuring Jeweller radio technology, the WaterStop maintains a secure, encrypted connection with the Ajax hub at a distance of up to 1,100 meters.
- Long Battery Life: Operates for up to 3 years on its pre-installed batteries, ensuring continuous protection even during power outages.
- Easy Installation: The electric actuator can be mounted onto the included high-quality RuB valve without any special tools, in one of four possible positions.
- Manual Override: A built-in lever allows for manual water shutoff in emergencies, providing a failsafe option that doesn't require power or a hub connection.
Advanced Automation for Complete Protection
The true power of the WaterStop is realized when it's part of a comprehensive Ajax security system. Configure simple automation scenarios that link the WaterStop to one or more LeaksProtect sensors. The moment moisture is detected, a command is sent to the WaterStop to immediately cut off the water supply, preventing a minor leak from becoming a major disaster. The system keeps you informed with instant, informative notifications directly to your smartphone.
