Remotely controlled water shutoff valve [1/2''] (white)

Brand : Ajax
PART #: Ajax WaterStop [1/2] (9NA) white

Introducing Ajax Systems WaterStop: This remotely controlled water shutoff valve offers advanced protection against water damage by allowing users to shut off water remotely. With a replaceable battery life of up to 3 years and a communication range of up to 1,100m with an Ajax hub, it ensures long-lasting reliability and flexibility in placement. Supporting automation scenarios, it can be integrated into your smart home system for enhanced convenience and control. Equipped with overcurrent protection and capable of electronic shutoff in just 5 seconds, it provides rapid response to water emergencies, helping to minimize potential damage.

Swift Action, Minimal Water Loss

WaterStop excels in delivering swift action while minimizing water loss. Under normal operating conditions, it shuts off the water within 5 seconds of command or automatically triggers the shut-off when LeaksProtect or a third-party sensor detects flooding. In fact, in a system with a ¾-inch pipe and 2.5 bar of pressure, WaterStop minimizes water loss to less than 1 liter, ensuring efficient water conservation.

UNLEASHING THE POWER OF AJAX WIRELESS TECHNOLOGIES

WaterStop harnesses the power of Ajax's state-of-the-art wireless technology, providing secure and efficient communication. With its long-range signal transmission of up to 1,100 meters in an open space, Ajax outperforms competing solutions. The system's automatic power adjustment and frequency hopping ensure energy efficiency and protection against interference and signal interception. For complex radio signal conditions, such as large houses or warehouses, the ReX range extender offers extended coverage and stable communication even through steel and concrete structures

TAILORED SOLUTIONS FOR EVERY SETTING

WaterStop is available in three versions (½” (DN 15), ¾” (DN 20), or 1” (DN 25)), featuring different valve options to cater to various demands. Whether it's a residential home or a large-scale business facility, WaterStop's compatibility with ISO 5211 standard ball valves allows for easy installation, ensuring a perfect fit for specific tasks and sizes.

COMPREHENSIVE MONITORING WITH PRO DESKTOP

For building administrators, PRO Desktop provides comprehensive monitoring of security, automation, and smart home devices. With real-time device statuses, event logs, and microclimate data, administrators can have a centralized view of the entire system, ensuring optimal control and quick response. The photo verification feature enables a visual assessment of the situation, aiding in the swift resolution of any issues. Additionally, installation engineers can remotely adjust settings and provide tailored services based on specific requirements.

EFFICIENT WATER LEAK PREVENTION

WaterStop ensures water shut-off when triggered by LeaksProtect or third-party leak detectors integrated into the Ajax system. Additionally, it automatically shuts off the water when the security system is armed, guaranteeing leak prevention even when you're away. For added convenience, WaterStop allows scheduled water supply control, enabling you to adjust specific timings to suit your needs. Furthermore, the device's communication failure detection system ensures prompt notification in case of any disruptions.

ENHANCED SECURITY AND INSTALLATION FEATURES

WaterStop incorporates anti-sabotage mount lockers, preventing unauthorized dismantling of the electric actuator. With the tamper alarm and control button locking features, WaterStop provides an additional layer of security, alerting users and the security company in case of any unauthorized tampering or manual shut-offs. The intuitive installation process and seamless connection to Ajax apps ensure a hassle-free experience, allowing for maintenance and repair in hard-to-reach places without disassembling the shutoff valve.
