A p rt of the w ter le k 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 notications on the alarm and activation of the scenario. In addition to
the scenario by the leak detector alarm, the installer can congure water shut-off by schedule or by security
mode change.
Powerful electric ctu tor nd m nu l control
WaterStop electric actuator features a maximum torque of
8.5 N•m. This power allows closing a stucked-up shutoff
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, dened by the position mark on the WaterStop enclosure or by
the position of the lever.
St nd rd type of shutoff v lve
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 IS O 5211 standard.
Therefore, a plumber can install a standardi z ed shutoff
valve, and an installer can then add the device to the
system.

Technical Data Sheet: WaterStop Jeweller
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 LeaksProtect leakage detector.
 By schedule — to shut off the water at a certain time.
 By security mode change — in case of arming and disarming.
 Upon pressing LightSwitch — for example, when the last employee leaves the oce premises.
 By pressing Button — for manually shutting off water in the event of an emergency.
 By temperature — to shut off water in the heating pipes for the winter.
Jeweller
communication technology
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, oces, 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 oces, restaurants,
cafés, and other public places. An alternative
mounting locker is included to complicate
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.

Technical Data Sheet: WaterStop Jeweller
The tamper is triggered when the electric actuator is removed from the shutoff valve. The hub regularly (with
a specied 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 notications 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 9–12 V⎓, 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 xed
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 shutoff
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.
