AJAX WaterStop Jeweller 1/2" (DN 15) Remote Controlled Water Shut-Off Valve (White)


The WaterStop Jeweller is a smart water shut-off valve. It operates as part of an automated water leak prevention system. It can be controlled in the Ajax app, via a button on the housing, a lever on the shut-off valve, or through automation scenarios.

The WaterStop communicates with the hub using the encrypted radio protocol Jeweller, and has an unobstructed communication range of up to 1100 meters.

FEATURES:

  • Four mounting positions
  • RuB valve included - ISO 5211 standard
  • Jeweller radio communication
  • Water shut-off in 5 seconds
  • Up to 1100 m communication range with Ajax hub
  • Up to 3 years battery life
  • Automation scenarios
  • Electric actuator protection against unauthorized removal
  • Button and lever for manual water shut-off
  • Automatic flood prevention with scenarios
  • Compatible with hot and cold water pipes
  • Overheating notifications
  • Optional power supply External
  • Remote control and configuration
  • Detailed notifications in the app

Cuts off the water supply in 5 seconds

WaterStop is equipped with a powerful actuator with up to 8.5 Nm of torque.
This is enough to close even a stuck valve without risk of damage.

Under normal operating conditions, WaterStop shuts off the water in 5 seconds after a command is issued, or automatically according to a scenario when LeaksProtect or a third-party sensor detects flooding.
In an installation with a ¾-inch pipe and 2.5 bar of mains pressure, less than 1 liter of water will leak.

In the Ajax-based water leak prevention system, each device operates on pre-installed batteries or has a backup power supply in the event of a power outage.
The system monitors the facility 24/7, ensuring that your property is protected.

  • Closes even a stuck valve
  • Suitable for facilities with unstable or no power supply

Protection at every level

WaterStop is suitable for controlling both hot and cold water and is ready to operate in harsh conditions.

Thanks to additional safety features, WaterStop is resistant to overcurrent and notifies of overheating, preventing failure of the electric actuator even in the event of a blocked shut-off valve.

  • Overheating Notification
  • Overcurrent Protection

Solid and Durable Brass Installation

WaterStop is available in three versions with different valve sizes: ½" (DN 15), ¾" (DN 20), or 1" (DN 25).
These are the most popular sizes used to meet every need, from residential to commercial.

Furthermore, the WaterStop electric actuator is compatible with all ball valves that meet the ISO 5211 standard.
Therefore, for specific tasks and sizes, a plumber can install a compatible valve available on the market, and the installer can easily connect the electric actuator to it.

Installation without construction work

The myth that flood protection systems are difficult to install has been debunked.
Ajax has eliminated expensive, time-consuming, and messy installations for customers and specialists.

Modern hardware and software have allowed us to implement advanced functions with significant autonomy in a compact format.

Ajax miniature water leak sensors work well in hard-to-reach places and do not require disassembly of the housing – they can be mounted on a horizontal surface without the need for mounting.

The shut-off valve is installed in the existing plumbing system.

The actuator unit requires no wiring and fits into confined spaces, as it has four possible mounting positions relative to the valve.

Stable performance for years

  • Batteries

    • No additional wiring required: WaterStop is autonomous and not dependent on the 110 or 220 V AC mains. Thanks to its three-year battery life and the lack of cables, the installation process requires significantly less time and effort.

      Ajax applications will notify the installer and users in advance of low battery levels. The batteries are replaceable, so after three years, the installer simply inserts new ones and WaterStop continues to operate as usual.

      • Up to 3 years of operation with pre-installed batteries.
      • In-app low battery warning.
      • Replaceable CR123A batteries.

  • External power supply.

    • When continuous shut-off valve operation is required or the installation site is subject to extreme temperatures, the batteries may discharge more quickly.

      The option of connecting a 9-12V power supply will be useful, eliminating frequent battery replacement and reducing maintenance costs. Pre-installed batteries act as a backup power source, so even in the event of a power outage, WaterStop continues to operate without a problem.

      • 9-12V⎓ Power Connection
      • Pre-installed batteries serve as a backup power source (9-12V⎓ power supply not included with WaterStop)

Unique Wireless Technologies

The Ajax system uses two-way secure radio communication based on the proprietary Jeweller protocol.
Supports block encryption and device authentication for each session with the hub to prevent tampering, spoofing, and data theft.

Ajax wireless technology has a radio range of up to 1,100 meters in open space, which is longer than competing solutions from other manufacturers.
Automatic power control makes it energy-efficient because it does not continuously use the maximum power of radio transmitters in the system's devices.

It is also more stable thanks to the use of less common radio frequencies.
To protect against radio interference and signal interception, Ajax hubs use frequency hopping: the system automatically changes the frequency within a given band and notifies the security agency and users of the interference.

  • Up to 1100 meters of radio communication with the hub
  • Encrypted two-way radio communication
  • Notifications about signal jamming and connection loss

Scalable and comprehensive

Use the ReX signal range extender in challenging radio conditions, such as large houses with thick walls or warehouses with multiple buildings.

ReX extends the range of all Ajax devices and manages their communication with the hub via the Jeweller protocol.
ReX 2, on the other hand, ensures stable communication even through steel and concrete via Ethernet, using wire as an additional communication channel.

Up to 5 signal range extenders can operate within a single Ajax system, double-extending the network to cover underground parking lots, basements, and metal hangars.

  • Up to 5 signal range extenders in a single system
  • Ethernet as an alternative communication channel
