AJAX WATER STOP 3/4 VALVE - WHITE

A part of the water leak detection system

WaterStop was designed for remote control of the water supply at the facility. The device combines a shutoff valve in one of three variations and an electric actuator. WaterStop can be controlled from anywhere where there is an Internet — Ajax apps allow checking the status and changing the position of the valve at any time. Upon the alarm of LeaksProtect or a third-party leak detector, WaterStop will automatically shut off the water in 5 seconds. All system users receive notifications on the alarm and activation of the scenario. In addition to the scenario by the leak detector alarm, the installer can configure water shut-off by schedule or by security mode change.

Powerful electric actuator and manual control

WaterStop electric actuator features a maximum torque of 8,5 N•m. This power allows closing a stacked-up shut off valve without breaking it. And under normal conditions —
shut off water 5 seconds after the command. The water supply can be controlled not only through apps and scenarios but also manually. For this, there is a button on the WaterStop enclosure and a lever on the shutoff valve mount. This is convenient, for example, when replacing an electric actuator or during the plumber's work. The valve's status can be seen in Ajax apps, defined by the position mark on the WaterStop enclosure or by the position of the lever.

Standard type of shutoff valve

The device is equipped with a Bonomi Industries shutoff valve suitable for hot and cold water. WaterStop is presented in three versions: with a DN15 (½"), DN 20 (¾"), or DN 25 (1") valve. WaterStop is compatible with shutoff valves manufactured according to the ISO 5211 standard. Therefore, a plumber can install a standardized shutoff valve, and an installer can then add the device to the system. Technical Data Sheet: WaterStop Jeweller 3 When moving, an installer can easily dismantle the WaterStop and install another compatible valve at a new location. The electric actuator is removed from the shutoff valve in a few seconds — without any tools.

Automation scenarios

Scenarios allow minimizing the routine actions and automatically shut off the water. Scenarios can be used to control the water supply in the following cases:

• By alarm — in case of an alarm of the Leaks Protect leakage detector.a
• By schedule — to shut off the water at a certain time.a
• By security mode change — in case of arming and disarming.a
• Upon pressing LightSwitch — for example, when the last employee leaves the office premises.a
• By pressing Button — for manually shutting off water in the event of an emergency.a
• By temperature — to shut off water in the heating pipes for the winter.

Jeweller is a radio protocol to provide fast and reliable two-way communication between hubs and connected devices. The protocol provides a wireless radio communication range of up to 1,100 m, which allows using the smart valve not only in a large house but in basements, offices, or warehouses. Jeweller transmits all necessary information. Users always have access to smart valve control in Ajax apps, regardless of the number of system devices. And also, at any moment, they can check the valve's status — whether it is open or closed.

Anti-sabotage protection

WaterStop can be installed in offices, restaurants, cafés, and other public places. An alternative mounting locker is included to protect against unauthorized disassembly. This locker is installed instead of the standard one to prevent disassembly of the electric actuator. Unlike a standard locker, it cannot be removed without tools.

The tamper is triggered when the electric actuator is removed from the shutoff valve. The hub regularly (with a specified frequency) checks the status of connected devices and informs about the loss of communication with any of them. All users and the CMS of the security company receive notifications about these events.

Smart design

WaterStop is a wireless device that runs on pre-installed batteries. The installer can connect a third-party power supply 9–12V⎓, 2 A if necessary. The electric actuator is mounted on the shutoff valve in four positions. The casing of the electric actuator does
not need to be disassembled for installation. It is fixed on the valve with a mounting locker without tools. This way, there is no risk of damaging the electronics.

Easy installation and connection

WaterStop is installed by two specialists: a plumber and an installer. We ensured that both of them were comfortable working with this product. A plumber can install a standard compatible shut off valve without an installer. He only needs to know the
dimensions of the electric valve. An installer can come on another day, install the electric actuator and integrate it into the Ajax security system. Pairing the device with the Ajax security system takes less than a minute. An installer needs to open the Ajax app, scan the QR code, and add a detector to a room and group.
