Operating Principle
WaterStop Jeweller is a smart water shutoff valve with remote control. It operates as part of the Ajax system’s automated water leak detection system. The valve can be controlled from anywhere in the world using Ajax apps, allowing users to check the status and change the position of the valve at any time.

Control via the App
WaterStop can control the water supply at the location using the Ajax apps. Notifications provide information about the device’s name, virtual room, activation time, and the user who opened or shut off the water supply.
To control the valve, open the Devices menu in the Ajax app and click the toggle in the WaterStop field. This will change the state of the valve contacts, either stopping or restoring the water supply. Users can remotely shut off the water supply, for example, in a country house.
In the Control menu, users can swipe up to access a list of automation devices connected to the hub. By pressing the switch in the WaterStop field, the valve state can be reversed, stopping or restoring the water supply.

Manual Control
WaterStop can also be controlled manually through Ajax apps. There are two ways to manually control the valve:

1. Button on the electric actuator enclosure: When pressed, the shutoff valve opens or closes. This method requires the electric actuator to be installed. The state of the shutoff valve can be checked in the Ajax app and by looking at the position of the mechanical indicator.
2. Lever on the mount: The lever on the mount can be used to manually control the water supply.

For more detailed information on using WaterStop Jeweller, please refer to the user manual.

Operating principle

1. The electric actuator controls the shutoff valve.
2. The shutoff valve is a Bonomi ball valve. WaterStop is supplied with a valve in one of three sizes: ½” (DN 15), ¾” (DN 20), or 1″ (DN 25).
3. The mount is installed between the shutoff valve and the electric actuator.
4. The mounting locker affixes the electric actuator to the shutoff valve. There are two options: standard (pre-installed) and alternative (for installation in public places).

Control via the app
WaterStop can control the water supply at the object using the Ajax apps. Notifications indicate the device’s name, a virtual room, activation time, and the user who opened or shut off the water supply.

Users can also control the water supply in the Control menu. To do this, a user must swipe up the Control menu. A swipe opens a list of automation devices connected to the hub. The valve state reverses by pressing the switch in the WaterStop ?eld, and the water supply stops or restores.

Manual control
Users can control the water supply at the object in Ajax apps and manually. There are two ways to control the WaterStop manually: a button on the electric actuator enclosure and a lever on the mount.

1. By button on the electric actuator enclosure. When pressed, the shutoff valve opens/closes. This method of water supply control works when the electric actuator is already installed. The state of the shutoff valve can be found in the Ajax app and by looking at the position of the mechanical indicator.
   The ability to control the water supply with a button on the enclosure can be disabled in the device settings.

2. By lever on the mount. An installer or plumber can turn the lever and open or shut the water without the tools. This method of controlling the water supply only works with the electric actuator removed. This control method is provided for manually shutting off the water supply during the installation of a shutoff valve, when installing an electric valve, or in emergencies. The water valve is open if the lever is along the shutoff valve. If the lever is across the valve, the water is shut off.

Automation scenarios

Security system scenarios help automate security, reduce the number of routine actions, and improve user experience. WaterStop supports the following types of scenarios:

• Alarm reactions.
• Security mode change responses.
• Scheduled actions.
• By pressing Button. Temperature protection.
• By pressing LightSwitch.
• By humidity.
• By CO2 concentration.

Scenarios by humidity and CO2 concentration are available when LifeQuality is added to the system. For example, using scenarios, the water supply can be turned off by the LeaksProtect leak detector alarms, according to a schedule, or when the security system is armed. More about scenarios

Temperature protection

To protect against overheating, the WaterStop electric actuator has temperature protection. It is activated when the WaterStop electric actuator is heated up to+60°C.
As soon as the protection is triggered, appropriate notifications are sent to the Ajax apps, and the water supply is stopped. Notification is sent to both end-user apps and PRO Desktop. This allows not only users but also representatives of service companies to monitor the status of devices at the objects.
As soon as the electric actuator temperature returns to normal, the water supply can again be controlled by WaterStop.

Stuck prevention

The ball shutoff valve should be serviced for stuck prevention. Without this procedure, a thick layer of limescale can form inside the valve over time. This deposit can impair or block the ability to turn the ball valve. As a result, it will be impossible to control the water supply at the object.
For stuck prevention, WaterStop can periodically open and close the shutoff valve. A PRO or a user with admin rights can set the maintenance period by creating a scheduled scenario. Learn more about scenarios

Protected with a tamper switch against unauthorized dismantling

The WaterStop kit includes two lockers:

• Standard (pre-installed) — for quick fixing of the electric drive on the shutoff valve. It is easily removed to access a shutoff valve or replace the electric actuator.
• Alternative (anti-sabotage) — installed instead of a standard locker. This locker cannot be removed from WaterStop without tools. It securely fixes the electric actuator on the shutoff valve and protects the electric actuator against unauthorized dismantling. This locker is used, for example, when installing the device in cafés, restaurants, hotels, factories, or places with public access.

Regardless of the locker selected, the WaterStop tamper will notify users and the monitoring company that the tamper has been triggered during an attempt to remove the electric actuator from the ball valve.
The locker can be installed on any of the four sides of the WaterStop.

Jeweller data transfer protocol
Jeweller is a radio protocol for fast and reliable two-way communication between a hub and connected devices. Jeweller supports block encryption with a ?oating key and authentication of devices at each communication session to prevent sabotage and device spoofing.
Ajax apps provided a system of ”hub–detector” polls to monitor connection with system devices and display their statuses. Polling frequency: from 12 to 300 seconds. The polling frequency is set by a PRO or a user with system setup rights in the hub settings.

Sending events to the monitoring station
The Ajax security system can transmit events and alarms to the monitoring app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other protocols. Which CMSs Ajax connects to
Only communication loss events between WaterStop and the hub (or the radio signal range extender) are transmitted to the CMS. Use PRO Desktop to receive all device events. Only communication loss events between WaterStop and the hub (or the radio signal range extender) are transmitted to the CMS. Use PRO Desktop to receive all device events.
The addressability of Ajax devices allows sending events and the type of the device, the name, the virtual room, and the security group assigned to it to the PRO Desktop and the CMS. The list of transmitted parameters may differ depending on the CMS type and the selected communication protocol.

The ID and device loop (zone) number are available in the device States

Selecting the installation site

The installation of WaterStop should be carried out by a specialist: a plumber or an installer. The list of authorized Ajax partners is available here.

WaterStop is installed on water supply or heating pipes. The device can control the supply of both cold and hot water.
40 bar is the maximum water pressure for which the bundled Bonomi ball valve is designed. Do not install the device on pipes that may be under greater pressure.
WaterStop can control water supply with temperatures from +5°C to +120°C. Do not install the device on water pipes with lower or higher temperatures.
WaterStop is not designed to control the supply of domestic or industrial gas or liquids besides water.

When choosing a location for the WaterStop, consider its dimensions. The intended location should have enough space to install the electric actuator in one of the four positions. A plumber or installer should have access to the device: for maintenance, repair, and replacement of a locker or electric actuator.
If a 9-12 V⎓ power supply is connected to the WaterStop, route the power cables to the device beforehand.
Consider the Jeweller signal strength when choosing a place to install the WaterStop. It is determined by the number of undelivered or corrupted data packets exchanged between the device and the hub or range extender over a certain period.

The icon in the Devices menu indicates the signal strength. The signal strength is also shown in the device states.

Signal strength value:

• Three bars — excellent signal strength.
• Two bars — good signal strength.
• One bar — low signal strength. Stable operation is not guaranteed. Crossed-out icon — no signal. Stable operation is not guaranteed.

Check the Jeweller signal strength at the installation site. WaterStop should have a signal strength of two or three bars. To roughly calculate the signal strength at the place of installation, use a radio communication range calculator.
With a signal strength of one or zero bars, the stable operation of the security system is not guaranteed. Use the radio signal range extender if the selected installation site has a signal strength of fewer than two bars.

Do not install a smart valve

• Outdoors. This may result in device failure or incorrect operation.
• In rooms with humidity and temperature that are outside the permissible limits. Doing so may cause the device to malfunction or not work correctly.
• In places with low or unstable signal strength. This can lead to a loss of connection between the  smart valve and the hub (or range extender).
• On pipes through which water is transported with a pressure of more than 40 bar.
• On pipes through which water with a temperature below +5°C or above +120°C is transported.
• On pipes through which domestic or industrial gas is transported.
• On pipes through which any liquid besides water is transported.

Installation

Before installing WaterStop, ensure that the optimal location of the device has been selected and that it complies with the requirements of this manual. When installing and operating the device, follow the general electrical safety rules for using electrical appliances and the requirements of electrical safety regulations. WaterStop electric actuator can be installed on a bundled Bonomi valve and a third-party one. The electric actuator is compatible with valves that comply with the ISO 5211 standard. Therefore, a plumber can install a third-party ball valve one day, and an installer can fix an electric actuator and connect the device to the Ajax system another day.

Adding to the system

Before adding a device

1. Install the Ajax app.
2. Create a user or PRO account if you don’t already have one. Add a compatible hub to the app, set the desired settings, and create at least one virtual room.
3. Make sure that the hub is on and has Internet access via Ethernet, Wi-Fi, and/or mobile network. This can be done in the Ajax app or by looking at the hub LED. It should light up white or green.
4. Make sure the hub is disarmed and does not start updates by checking its status in the Ajax app.
   Only a PRO or a user with administrator rights can connect WaterStop to the hub.

Connecting to the hub
WaterStop should be within the coverage area of the hub radio network to connect to the hub. To work via a radio signal range extender, it is necessary to pair the smart shutoff water valve to the hub and then connect it to the range extender (via settings).
The hub is incompatible with devices operating at different frequencies. The radio frequency range of the device may vary by region. It is recommended to buy and use Ajax devices in the same region. Please contact for information on the operating frequency range.
WaterStop only works with one hub. When connected to a new hub, the smart water shutoff valve stops sending commands to the old one. Once added to a new hub, the smart water shutoff valve is not removed from the list of devices of the old hub. This must be done through the Ajax app.

To connect WaterStop to a hub:

1. Open the Ajax app. Sign in to the account.

2. If your account has access to more than one hub or if you are using the PRO app, select the hub to which you want to add the device.

3. Go to the Devices menu. Press Add Device.

4. Give a name to the smart valve.

5. Scan or enter the QR code (located on the device enclosure and its packaging).

6. Select a virtual room and a security group (if the Group mode is enabled).

7. Click Add Device — the countdown will begin.
   If the maximum number of devices is added to the hub, when you try to add the smart valve in the Ajax app, you will get a notification about exceeding the device limit. The maximum number of devices that can be connected to the hub depends on the central unit model.

8. Turn on WaterStop by holding the power button for three seconds.

After a successful connection, WaterStop will appear in the list of hub devices. If connection fails, turn the device off and try again in 5 seconds. Refreshing the device statuses in the list depends on the Jeweller (or Jeweller/Fibra) settings. The default value is 36 seconds.
