The Ajax WaterStop - 3/4" (8EU) is a professional, remotely controlled water shut-off valve designed to prevent flooding by automatically stopping the water supply when a leak is detected by the Ajax security system.
Automated Flood Prevention: Automatically shuts off water in as little as 5 seconds when an Ajax leak detector is triggered or via pre-set automation scenarios.
Remote Management: Control and monitor the valve status from anywhere in the world using the Ajax mobile or desktop applications.
Reliable Construction: Combines a high-quality Bonomi brass shut-off valve with a powerful electric actuator providing up to 8.5 N·m of torque to handle even stuck valves.
Flexible Automation: Supports scheduled shut-offs, actions based on security mode changes (arming/disarming), or triggers from other Ajax devices like LightSwitch or Button.
Anti-Sabotage Design: Features a tamper button to alert users if the actuator is removed and includes an anti-sabotage locker to prevent unauthorized dismantling.
Dual Power Options: Operates for up to 3 years on four pre-installed CR123A batteries or can be connected to an optional 7.514 V external power supply.
Jeweller Wireless Technology: Secure, encrypted radio communication with a range of up to 1,100 meters from the Ajax hub.
