AJAX WATERSTOP WIRELESS WATER SHUTOFF VALVE 1" BLACK 2Y 62603.154.BL3
Remotely controlled water shutoff valve DN 25 (1")
WaterStop is 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 notifications on the alarm and activation of the scenario. In addition to
the scenario by the leak detector alarm, the installer can configure water shut-off by schedule or by security
mode change.
Automation scenarios by alarm of the leak detector, security mode change, and schedule
The stuck prevention is adjustable with maximum interval of 1 week
Bonomi Industries shutoff valve DN 25 (1")
Up to 3 years of operation on pre-installed batteries
Remote control and configuring via Ajax apps
Water shut-off is controlled with a button on the electric actuator and a lever on the shutoff valve
Up to 1,100 m Radio signal range between the device and a hub or radio signal range extender without obstacles
Mounting lockers to complicate unauthorized disassembly of the electric actuator
Optional connection of a third-party power supply unit 9–12 V⎓, 2 A
Pairing with the system via QR code
WaterStop is compatible with shutoff valves manufactured according to the ISO 5211 standard.
Therefore, a plumber can install a standardized shutoff valve, and an installer can then add the device to the system.
