Product information

Description

The Ajax WaterStop is a professional-grade wireless automatic water shut-off valve designed to provide reliable protection against flooding in residential and commercial environments. By integrating seamlessly into the Ajax security ecosystem, this device enables remote control of water supply and automatic shut-off in the event of a leak. Powered by long-lasting batteries and utilizing advanced radio communication, it ensures continuous monitoring and rapid response to potential water damage.

Advantages

The WaterStop features a powerful electric actuator capable of delivering 8.5 N•m of torque, allowing it to close even stuck valves within 5 seconds. Its wireless design eliminates the need for complex wiring, making installation straightforward and non-intrusive. The system is highly autonomous, offering up to 3 years of battery life, with the option for external power for high-demand scenarios. Furthermore, the device is built for durability, featuring protection against overcurrent and overheating, and it supports secure two-way communication to prevent signal interference or tampering.

Suitable for

  • Residential homes and apartments for automated leak prevention
  • Commercial buildings and offices requiring remote water management
  • Hard-to-reach plumbing areas such as technical boxes or pipe tunnels
  • Integration with existing Ajax security systems and leak detectors

When it may not be suitable

This device is designed specifically for use within the Ajax security ecosystem and requires an Ajax hub to function. It is not intended for standalone operation without a compatible hub. Additionally, while the actuator is robust, it must be installed on a compatible ball valve that meets the ISO 5211 standard to ensure proper mechanical operation.

Key specifications

  • Wireless technology: Jeweller RF protocol
  • Operating frequency: 866–922 MHz
  • Power source: CR123A batteries (3V) or optional 9–12V DC external supply
  • Shut-off time: 5 seconds
  • Torque: 8.5 N•m
  • Dimensions: 70 x 104 x 140 mm
  • Compatibility: Ball valves meeting ISO 5211 standard

How to use

Installation involves mounting the shut-off valve into your existing plumbing system, followed by attaching the electric actuator to the valve platform. The actuator can be positioned in four different orientations to fit tight spaces. Once physically installed, the device is added to the Ajax system via the mobile application by scanning a QR code. Users can then configure automated scenarios, such as shutting off water when the system is armed or when a leak detector is triggered, and manage the valve status remotely from anywhere with an internet connection.

What to consider before purchase

  • Ensure your existing ball valve is compatible with the ISO 5211 standard
  • Verify that you have an Ajax hub installed at the location
  • Check the pipe size to ensure the valve matches your plumbing requirements
  • Consider if an external power supply is needed for your specific installation environment
Usage recommendations: For optimal performance, test the valve operation periodically through the Ajax app. If the device is installed in an area with extreme temperatures, consider using an external 9–12V power supply to extend the lifespan of the backup batteries and ensure consistent operation.
