Hardware
Water shut-off in 7 seconds
Ajax WaterStop is equipped with a powerful actuator of up to 8.5 N•m torque. This is enough to shut off even a stuck-up valve without the risk of damaging it. Under normal operating conditions, Ajax WaterStop shuts off the water in 7 seconds after the command or automatically by scenario whenever LeaksProtect or a third-party sensor detects flooding. In a setting with a ¾-inch pipe and 2.5 bar of pressure in the water supply system, less than 33 oz of water will leak out.
Inside the water leak prevention system based on Ajax, every device operates either on pre-installed batteries or has a backup power supply in case of a blackout. The system monitors the facility 24/7, giving you complete peace of mind that the property is protected.
Shuts even a stuck-up valve
Suitable for facilities with unstable or no power supply
Protected on every level
Ajax WaterStop is suitable for controlling both hot and cold water supplies and is ready to operate in challenging environments. With additional protection, Ajax WaterStop withstands overcurrent and notifies about overheating, making it impossible for the electric actuator to fail even when the shutoff valve is stuck.

One-stop solid brassware
Ajax WaterStop is available in three versions with different valve options: ½” (DN 15), ¾” (DN 20), or 1” (DN 25). Those are the most common sizes used to cover any demand, from residential to business facilities. Also, the Ajax WaterStop electric actuator is compatible with all ball valves that meet the ISO 5211 standard. So when it comes to specific tasks and sizes, a plumber installs an available on every market compatible valve, and the installation engineer easily connects the electric actuator.
How to check if Ajax WaterStop is compatible with a third-party shutoff valve
Installation without any construction involved
The myth about anti-flood systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for clients and professionals. Cutting-edge hardware and software engineering allowed us to implement advanced capabilities with significant autonomy in a compact size. Miniature Ajax water leak detectors suit hard-to-reach places and do not require enclosure disassembling — they can be installed on a horizontal surface without attaching. The shutoff valve is installed in line with an existing plumbing system. The actuator unit does not require wires and fits limited spaces, having four possible installation positions towards the valve.
Autonomous operation
Stable performance for years
Batteries
No additional cable routing is required: Ajax WaterStop is autonomous and does not depend on the 110 or 220 V~ grid. With a 3-year battery life and no wires, the installation process takes much less time and effort. Ajax apps will notify an installation engineer and users about the low battery level in advance. The batteries are replaceable — so after three years, the installer pops the new ones, and Ajax 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 a constant shut-off valve operation is required or the installation place uses extreme temperatures, the batteries can discharge faster. An option to connect a 9–12 V⎓ power supply will come in handy, eliminating frequent battery replacement and reducing service costs. And the pre-installed batteries will serve as a backup, so even in a power outage Ajax WaterStop continues to operate without any problem.

Unique wireless technologies
The Ajax system uses two-way secure radio communication based on Jeweller proprietary protocol. It supports block cipher encryption and device authentication on every session with the hub to prevent sabotage, spoofing, or data theft.
Ajax wireless technology has up to 3,609 ft of radio signal communication range in an open space, making it on average longer than competing solutions from different manufacturers. Automatic power adjustment makes it energy efficient by not using the maximum power of radio transmitters in system devices on a regular basis. It is also more stable, using less noisy radio frequencies. For protection against radio interference and signal interception, Ajax hubs use frequency hopping: the system automatically changes frequency within a band and notifies the security company and users about the jamming.

Encrypted two-way radio communication
Notifications about jamming and connection loss
The Ajax radio protocol uses polling to display current device statuses and transmits alarms, events, and all the readings into the Ajax apps. Jeweller features encryption and authentication to prevent spoofing.

Software
All data at a glance
Intuitive Ajax apps provide all information in real-time from anywhere the Internet is available, on a smartphone or PC. Users can check the device state and control the water supply remotely — any action can be done with one click.
The Ajax system instantly notifies about events with informative notifications: security companies and users know exactly which device triggered, when and where it happened. The system controls each device state and reports if there is a malfunction or if it's time to replace the batteries.
Ajax WaterStop can be configured at any time from anywhere, as long as there is an Internet connection. It takes seconds to change the settings or reconfigure the scenario.
The event log records 500 recent events within the system. The data is explicit with the device, time, and description of the event. It helps to reconstruct the actual event and find the causes to obtain comprehensive information for the insurance company.
Full monitoring for the building
With PRO Desktop, building admin staff can observe security, automation, and smart home devices. Device statuses, event log, and microclimate data — the operator has a complete picture in one intuitive interface, all informative and centralized. And photo verification of alarms from detectors of the MotionCam lineup will help to find out the situation at the protected facility and quickly respond to it. The installer can remotely change the settings and provide additional services according to the object specifics.
Advanced automation for greater safety
Ajax WaterStop is a part of the Ajax ecosystem. Using scenarios , it can interact with automation devices and PhOD detectors of the MotionCam lineup. Whether it’s a minor water leak or a massive flooding, Ajax WaterStop shuts off the water in a matter of seconds. At the same time, MotionCam (PhOD) sends pictures to Ajax apps to identify what causes the water leak and assess the possible damage. And to prevent emergencies, automatic water supply control will turn off the water when no one is using it — a reliable combination of security and automation that runs like a Swiss watch.

Ajax WaterStop — remote-controlled water stop valve
The Ajax WaterStop tap allows you to remotely shut off the water supply in the room under the control of the Ajax security system. The device combines a high-quality Bonomi Industries valve and an electric actuator with a control unit. The faucet to control the water supply is connected to the control panel via the secure wireless Jeweller protocol. Ajax WaterStop can be controlled remotely from anywhere worldwide simply by accessing the Internet. Ajax's applications for PCs and mobile phones allow you to check the status and change the position of the valve at any time. The water stop valve from Ajax WaterStop will automatically turn off the water in 7 seconds on the alarm of the LeaksProtect water leakage sensor or another water leakage sensor. At the time of an alarm, all users connected to the system and the security company will receive a notification about the alarm and the scenario activation. In addition to the scenario of leakage, it is possible to set the shutdown of water at a particular time or when the security system becomes armed.Features of Ajax WaterStop remote controlled water shut off faucet
The water stop valve is available in black and white. The device is compatible with pipes for supplying cold and hot water. To shut off the water, an electric drive is used, which is protected from overheating and can operate at temperatures up to 60 °C at the installation site. The built-in tamper alarm reports an attempt to tear the case off the mounting platform. The Ajax WaterStop faucet works with the Jeweller wireless communication protocol, which allows communication with the security system control panel at 1100 m without obstacles. Management and configuration take place remotely using Ajax applications. Jeweller radio technology provides two-way communication between the alarm central and the water shutoff valve and protects the device from forgery with block encryption with a floating key. Also, notifications to the application are sent instantly. The applications for PCs and smartphones also display the current status of the tap to shut off the water: open/closed, the status of the battery charge, external power supply, and communication with the control panel. The radio signal strength is automatically adjusted to reduce power consumption and interference. RF hopping is used to prevent radio interference and jamming. Loss of communication is detected within 36 seconds, this time depending on the settings of the communication technology. The valve has an input for an external power supply of 9 V⎓. The Bonomi Industries valve is included. And it works with a temperature range from -20°C to +170°C. With the help of the valve, the water is blocked in 7 seconds. This value may increase due to contamination of the shutoff valve. There is a lever on the platform to manually shut off the water supply in emergencies. Water supply control does not require tools. There is a button on the body of the electric drive for manual control. When pressed, the shutoff valve opens/closes. LED indication using the color of the LED backlight of the Ajax logo indicates the state of the drive.The Ajax WaterStop faucet supports automation scenarios such as:
- Responds to water leakage sensor alarms.
- To change the security mode.
- Performs scheduled activities.
- It fires when a Button is pressed.
- Works on temperature.
- Activated by pressing LightSwitch.
