WaterStop Jeweller User Manual

Introduction

WaterStop Jeweller is a smart water shutoff valve that operates as part of an automated water leak prevention system. It can be controlled via Ajax apps, a button on its enclosure, a lever on the shutoff valve, and through automation scenarios.

An Ajax hub is required for operation. A list of compatible hubs and range extenders is available here.

WaterStop communicates with the hub using an encrypted Jeweller radio protocol, offering a communication range of up to 1,100 meters without obstacles. It runs on pre-installed batteries for up to three years and can also be powered by a third-party power supply unit (7.5–14 V=, up to 1.8 A).

You can Buy WaterStop.

Operating Principle

WaterStop Jeweller is a smart water shutoff valve with remote control, operating as part of the Ajax system's automated water leak prevention. It can be controlled from anywhere globally via the Internet through Ajax apps, allowing users to check status and change the valve position at any time.

WaterStop consists of:

• The electric actuator that controls the shutoff valve.
• A Bonomi Industries ball valve, available in ½", ¾", or 1" sizes.
• A mount installed between the shutoff valve and the electric actuator.
• A mounting locker that secures the electric actuator to the shutoff valve, available in standard (pre-installed) and anti-sabotage options. Learn more.

Control via the App

WaterStop allows water supply control through Ajax apps. Notifications provide the device's name, virtual room, activation time, and the user who operated the valve.

By toggling the WaterStop field in the Devices menu of Ajax apps, the valve state changes, stopping or restoring the water supply. This enables remote water shutoff, for instance, in a country house.

Users can also control the water supply via the Control menu. Swiping up the Control menu reveals a list of connected automation devices. The valve state is reversed by pressing the switch in the WaterStop field.

Manual Control

WaterStop can be controlled manually via two methods: a button on the electric actuator enclosure and a lever on the mount.

• By button on the electric actuator enclosure: Pressing the button opens or closes the shutoff valve. This works when the electric actuator is installed. The valve state can be confirmed in the Ajax app or by observing the mechanical indicator. The ability to control the water supply via the enclosure button can be disabled in device settings.
• By lever on the mount: Installers or plumbers can use the lever to open or shut off water without tools. This method is only functional when the electric actuator is removed. It is useful for manually shutting off water during installation or in emergencies. The water valve is open if the lever is aligned with the shutoff valve; it is shut off if the lever is across the valve.

Automation Scenarios

Security system scenarios automate security, reduce routine actions, and enhance user experience. WaterStop supports scenarios such as:

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

Scenarios related to humidity and CO2 concentration are available when LifeQuality is added to the system.

For example, scenarios can turn off the water supply based on LeaksProtect leak detector alarms, a schedule, or when the security system is armed. More about scenarios.

Out of Range Temperature Notification

To prevent overheating, WaterStop notifies users when its temperature reaches +60°C. Notifications are sent to both end-user apps and PRO Desktop, allowing users and service companies to monitor device status. This notification does not affect the primary function of shutting off water. The notification is also sent when the device temperature returns to normal.

⚠️ To avoid overheating, installing WaterStop in a ventilated area is recommended. If the device temperature exceeds +60°C, consider changing the installation site and operating conditions.

Stuck Prevention

The ball shutoff valve requires periodic servicing to prevent it from getting stuck due to limescale buildup. Without this, the valve's ability to turn can be impaired or blocked, making water supply control impossible.

For stuck prevention, WaterStop can periodically open and close the shutoff valve. A PRO or an administrator can set this maintenance period via a scheduled scenario. Learn more about scenarios.

Protected with a Tamper Switch

WaterStop is protected against unauthorized dismantling by a tamper switch. The device notifies users and the monitoring company if an attempt is made to remove the electric actuator from the ball valve.

The WaterStop kit includes two mounting lockers:

• Standard (pre-installed) locker: For quick fixing of the electric drive on the shutoff valve. It is easily removed to access the valve or replace the electric actuator. Suitable for private houses, flats, or other non-public places.
• Anti-sabotage locker: Installed instead of the standard locker to complicate unauthorized disassembly of the electric actuator. It is used in restaurants, laundries, factories, and other public or crowded sites. Tools are required to remove this locker.

The locker can be installed on any of the four sides of WaterStop.

Jeweller Data Transfer Protocol

Jeweller is a radio protocol for fast and reliable two-way communication between a hub and connected devices. It supports block encryption with a floating key and device authentication to prevent sabotage and spoofing.

Ajax apps use a "hub-detector" polling system to monitor device connections and statuses. Polling frequency ranges from 12 to 300 seconds, configurable by a PRO or user with system setup rights in the hub settings. Learn more.

Sending Events to the Monitoring Station

The Ajax system transmits events and alarms to the PRO Desktop monitoring app and Central Monitoring Stations (CMS) via protocols like SurGard (Contact ID), SIA DC-09 (ADM-CID), and ADEMCO 685. Which CMSs Ajax connects to.

Only communication loss events between WaterStop and the hub (or range extender) are sent to the CMS. PRO Desktop is used to receive all device events.

Ajax devices' addressability allows sending event details, device type, name, virtual room, and security group to PRO Desktop and CMS. The transmitted parameters may vary based on the CMS type and protocol.

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

Selecting the Installation Site

Installation of WaterStop should be performed by a specialist, such as a plumber or installer. A list of authorized Ajax partners is available here.

Selecting the installation site for WaterStop with bundled Bonomi Industries shutoff valve

Consider the following when choosing an installation location:

1. WaterStop dimensions: Ensure sufficient space for the electric actuator in one of the four positions. The installer needs access for maintenance, repair, or locker/actuator replacement.
2. Diameter of the bundled Bonomi Industries shutoff valve: The valve's diameter must match the pipe diameter.
3. External power supply connection: If using an external power supply, provide space and route cables. Recommended parameters: 9 or 12 V=, current up to 1.8 A.
   ⚠️ An external power supply connection must comply with general electrical safety rules and regulations.
4. Use WaterStop only for pipes that carry water: Suitable for cold or hot water pipes with temperatures from +5°C to +120°C. Do not install on pipes with lower or higher temperatures.
   ⚠️ WaterStop is not designed for domestic or industrial gas or liquids other than water.
5. Pipe pressure: Must not exceed 10 bar. Do not install on pipes with greater pressure.
6. Jeweller signal strength: Check signal strength at the installation site. WaterStop requires two or three bars for optimal operation. Use a radio communication range calculator for estimation. Signal strength of one or zero bars may compromise system stability; use a radio signal range extender if signal strength is less than two bars.
7. Temperature and humidity levels: The operating range is +0°C to +60°C; operating humidity is up to 95%.

ℹ️ Only a PRO or a user with administrator rights can connect WaterStop to the hub.

Connecting to the hub

WaterStop must be within the hub's radio network coverage area. To use a radio signal range extender, pair the valve to the hub and then connect it to the extender.

The hub is incompatible with devices operating at different frequencies. Radio frequency ranges vary by region; it's recommended to buy and use Ajax devices from the same region. Contact technical support for frequency range information.

WaterStop works with only one hub. Connecting to a new hub stops commands to the old one. The valve remains listed in the old hub's devices until removed via the Ajax app.

To connect WaterStop to a hub:

1. Open the Ajax app and sign in.
2. If you have access to multiple hubs or use the PRO app, select the desired hub.
3. Go to the Devices menu and press Add Device.
4. Give the smart valve a name.
5. Scan or enter the QR code (on the device or packaging).
6. Select a virtual room and security group (if Group mode is enabled).
7. Click Add Device; the countdown will begin.

ℹ️ If the hub limit is reached, adding the smart valve will trigger a notification. The maximum number of devices depends on the central unit model.

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

Upon successful connection, WaterStop appears in the hub's device list. If connection fails, turn the device off and try again in 5 seconds. Device status refresh depends on Jeweller (or Jeweller/Fibra) settings (default is 36 seconds).
