By clicking the toggle in the WaterStop eld in the Devices menu of the Ajax
apps, the state of the valve contacts change to the opposite, and the water
supply will stop or restore. Thus, a user can, for example, remotely shut off the
water in a country house.
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.

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.
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 .

For example, using scenarios, the water supply can be turned off by the
leak detector alarms, according to a schedule, or when the
security system is armed.
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 notications are sent to the
Ajax apps, and the water supply is stopped. Notication 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.

dismantling
Standard mounting locker Alternative mounting locker
The WaterStop kit includes two lockers:
Learn more about scenarios
Standard (pre-installed) — for quick xing 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 xes
the electric actuator on the shutoff valve and protects the electric actuator
against unauthorized dismantling. This locker is used, for example, when

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

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:
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
.
With a signal strength of one or zero bars, the stable operation of the security
system is not guaranteed. Use the if the selected
installation site has a signal strength of fewer than two bars.
Do not install a smart valve
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.

Connecting external power supply
WaterStop runs up to 3 years from the bundled batteries. The device is equipped
with terminals connecting a third-party 9-12 V⎓ power supply. 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. Use
only a grounded power source. Do not disassemble the device under voltage. Do not use
the device with a damaged power cable.

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.
