Operating principle
Ajax WaterStop Jeweller is a smart water shutoff valve with remote control. Operates as part of the Ajax system’s automated water leak prevention system.
Ajax WaterStop can be controlled from anywhere in the world where there is the Internet — Ajax apps allow checking the status and changing the position of the valve at any time.
Ajax WaterStop consists of the following blocks:
- The electric actuator controls the shutoff valve.
- The shutoff valve is an RuB valve. Ajax WaterStop is supplied with a BSP parallel threads valve in one of three sizes: ½” (DN 15, 15 mm), ¾” (DN 20, 20 mm), or 1″ (DN 25, 25 mm).
- The mount is installed between the shutoff valve and the electric actuator.
- The mounting locker fixes the electric actuator on the shutoff valve. There are two options: standard (pre-installed) and anti-sabotage (for installation in public places).
Control via the app
Ajax WaterStop can control the water supply at the object using Ajax apps. Notifications indicate the device’s name, a virtual room, activation time, and the user who opened or shut off the water supply.
By clicking the toggle in the Ajax WaterStop field in the Devices
Users can also control the water supply in the Control
Manual control
Users can control the water supply at the object in Ajax apps and manually. There are two ways to control Ajax WaterStop manually: a button on the electric actuator enclosure and a lever on the mount.
-
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 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.
- 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. Ajax 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.
Out of range temperature notification
To prevent overheating, Ajax WaterStop notifies you when it heats up to +60°C.
The notification is sent to both end-user apps and PRO Desktop. Thus, not only users but also representatives of service companies can monitor the status of devices at the objects. The option does not affect the Ajax WaterStop main task to shut off the water.
The notification is also sent to Ajax apps when the device temperature returns to normal.
To avoid overheating, we recommend installing Ajax WaterStop in a ventilated area. If the device temperature tops +60°C, we suggest changing the device installation site and operating conditions.
Stuck prevention
If not in use, 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.
The stuck can be avoided by the Preventive maintenance feature. This feature allows you to set the Ajax WaterStop Jeweller to automatically open and close the valve at a selected time and period (available Maintenance interval: 7, 30, and 90 days).
The Preventive maintenance feature is available for devices with firmware version 5.60.1.64 or later, operating with hubs with OS Malevich 2.24 or later.
The Preventive maintenance feature is activated only when the valve is open and there are no other conditions that make it impossible to perform preventive maintenance. Otherwise, the Preventive maintenance cannot be performed, the error information is displayed in the device’s states in the Ajax app, and the user receives a corresponding push notification. If failed to perform the procedure automatically, the device will not attempt to re-perform it later, so to execute the Preventive maintenance procedure, the user should open the valve manually or via the Ajax app.
Preventive maintenance is postponed for the selected Maintenance interval after each opening of the valve.
Protected with a tamper switch against unauthorized dismantling
|
|
|
| Standard mounting locker | Anti-sabotage mounting locker |
The Ajax WaterStop kit includes two lockers:
- Standard (pre-installed) locker — 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.
- Anti-sabotage locker — installed instead of the Ajax WaterStop’s standard locker. Use the tools to remove the anti-sabotage locker. The anti-sabotage locker securely fixes the electric actuator on the valve and makes it harder to remove the electric actuator if someone tries it unauthorized. This locker is used, for example, when installing the device in cafes, restaurants, hotels, factories, or public access sites.
Regardless of the selected locker, Ajax 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 Ajax 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 floating 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 system can transmit events and alarms to the PRO Desktop monitoring app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other protocols.
Only communication loss events between Ajax 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.

Connecting external power supply
Ajax WaterStop runs up to 3 years from the bundled batteries. The device is equipped with terminals connecting a third-party 7.5–14 V⎓, 1.8 A power supply unit. The recommended parameters of the external power supply are 9–12 V⎓, 2 A.Use a round 2 x AWG22 power cable with an external diameter of 3.0–3.7 mm to connect an external power supply.
When powered by the external power supply, Ajax WaterStop will turn on if it was turned off earlier.
The connection of the external power supply is recommended to avoid rapid discharge of batteries in the case of installation in places characterized by low temperatures or when frequent water shutoffs are reported.
When external power is connected, the pre-installed batteries are used as a backup power source. Do not remove them when connecting the power supply.
Before installing the device, be sure to check the insulation of the wires for damage. We recommend using a grounded power source. Do not disassemble the device under voltage. Do not use the device with a damaged power cable.
To connect external power supply:
- Shut off the water if necessary.
- Turn off Ajax WaterStop if it was on by holding the on/off button for 3 seconds.
- Pull out the mounting locker while holding the solenoid valve.
- Remove the electric actuator from the shutoff valve.
- Place the front side of the device with the Ajax logo on it on a soft cloth so as not to scratch the enclosure.
- Unscrew the protective plug on the bottom of the electric actuator enclosure using a hexagon (⌀ 3 mm).
- Loosen the screws with a PH1 cross-head screwdriver.
- Turn the electric actuator over while holding the front and back of the enclosure.
- Remove the front part of the electric actuator enclosure.
- Pass the de-energized power supply cable through the bundled sealing nut and silicone seal. The silicone seal is located in the electric actuator enclosure under the protective plug.
- Connect the cable to the terminals observing polarity. Polarity is marked on the plastic.
- Tighten the sealing nut on the bottom of the electric actuator enclosure (instead of the protective plug).
- Reinstall the front part of the device enclosure. The lid can be installed only in one (correct) position.
- Turn the device over while holding the front and back of the enclosure.

- Add at least one virtual room.
- Add a compatible hub to the space. Ensure the hub is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.
- Ensure the space is disarmed, and the hub is not starting an update by checking statuses in the Ajax app.
Only a PRO or a space admin with the rights to configure the system can add a device to the hub.
Connecting to the hub
Ajax 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 technical support for information on the operating frequency range.
Ajax 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 Ajax app.
To connect Ajax WaterStop to a hub:
- Open Ajax app. Sign in to the account.
- If your account has access to more than one space or if you are using the PRO app, select the space to which you want to add the device.
- Go to the Devices
menu. Press Add Device. - Give a name to the smart valve.
- Scan or enter the QR code (located on the device enclosure and its packaging).
- Select a virtual room and a security group (if the Group mode is enabled).
- 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 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.
- Turn on Ajax WaterStop by holding the power button for three seconds.
After a successful connection, Ajax WaterStop will appear in the list of hub devices. If connection fails, turn the device off and try again in 7 seconds. Refreshing the device statuses in the list depends on the Jeweller (or Jeweller/Fibra) settings. The default value is 36 seconds.

Malfunctions
If a malfunction is detected in Ajax WaterStop (for example, there is no connection with the hub or range extender), the malfunction counter is displayed in the device field in Ajax app.
Malfunctions are displayed in the shutoff valve States. Fields with malfunctions will be highlighted in red.
Malfunction is displayed if:
- Temperature protection was activated.
- There is no connection between Ajax WaterStop and the hub (or range extender).
- The Ajax WaterStop batteries are discharged.
- Valve is stuck.
Maintenance
Regularly check the operation of the device: check how Ajax WaterStop controls the water supply. The optimal frequency of checks is once every three months. Clean Ajax WaterStop enclosure from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use substances that contain alcohol, acetone, petrol, and other active solvents to clean the device.
We recommend turning on the Preventive maintenance feature or setting up a scheduled scenario to open and close a valve periodically. For example, once a week for one minute. This will protect the valve from getting stuck and extend its life.
