Water shut-off in 5 seconds
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, WaterStop shuts off the water in 5 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 than1 literof 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
WaterStop is suitable for controlling both hot and cold water supplies and is ready to operate in challenging environments. With additional protection, 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
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 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.

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.

Batteries
No additional cable routing is required: 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 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 WaterStop continues to operate without any problem.

• 9-12 V--- power supply connection
• Pre-installed batteries as a backup power source

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 to1,100 metersof 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.

• Up to1,100 metersof radio communication range with a hub
• Encrypted two-way radio communication
• Notifications about jamming and connection loss

Jeweller
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.

Scaled and comprehensive
Use the ReX range extender for complex radio signal conditions like large houses with thick walls or warehouses with several buildings. ReX boosts the range of all Ajax devices and manages their communication with the hub via Jeweller. And ReX 2 assures stable communication even through steel and concrete via Ethernet using the wire as the additional communication channel. Up to 5 range extenders can operate within one Ajax system to expand the network twice as big, covering underground parking, basements, and metal hangars.

• Up to 5 range extenders within one system
• Ethernet as an alternative communication channel

All data at a glance

• In-app control
• Data-rich notifications
• Remote configuration
• Detailed event log

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.

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
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, 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.

Water leak prevention system
WaterStop automatically shuts off the water when LeaksProtect or any other third-party leak detector integrated into Ajax via Transmitter or MultiTransmitter detects a water leak.

Communication failure detection
The device regularly exchanges data with the hub. With maximum ping interval settings available (3 data packages once in 12 seconds), it takes only 36 seconds to identify communication loss and notify the security company and users about the incident.

Anti-sabotage mount lockers
Anti-sabotage mount locker prevents the electric actuator from dismantling unauthorized unless special tools are used. So WaterStop can be installed in offices, restaurants, libraries, and other public places without worries.

Tamper alarm
The enclosure is hardwired with a tamper button, which notifies the security company and users once the electric actuator is dismantled from the mount. Also, it helps to incur that the electric actuator is installed and fixed on the shutoff valve correctly.

Control button locking
The control button on the enclosure can be locked in Ajax apps to prevent accidental or unauthorized manual shut-offs.

Intuitive installation and connection
The WaterStop actuator is ready to operate straight out of the box. It installs on the mounting platform without tools and enclosure disassembling in four possible positions towards the valve. A plumber installs a bundled or another compatible shutoff valve in advance without an installation engineer's presence - all he needs to know is the electric actuator dimensions.

Ajax apps help quickly make the device a part of the automated system. There is no need to visit the object to disable the device or change the settings. The design allows maintenance and repair in hard-to-reach places: pipe tunnels, technical boxes, walls, etc. It is possible to replace the actuator unit without dismantling the shutoff valve.
