WaterStop

Ajax WaterStop Jeweller

Remotely controlled water shutoff 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.

Not a drop of problems

Ajax WaterStop automatically shuts off the water in 7 seconds at a facility with an Ajax security system if LeaksProtect or a third-party water leak detector is triggered. The device combines a high-quality valve and a powerful electric actuator. You can control Ajax WaterStop and check its status from anywhere in the world — all you need is an Internet connection and an Ajax app. You can also create a scenario to shut the water off at a specific time or when arming the system.

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 1 liter 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.

Up to 1,100 m

range of communication with an Ajax hub

Compatible with cold and hot water pipes

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.

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.

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.
