WaterStop Jeweller is a smart water shutoff valve. Operates as part of an automated water leak detection system. Controls it in Ajax apps, through a button on the enclosure, a lever on a shutoff valve, as well as automation scenarios. WaterStop communicates with the hub using an encrypted Jeweller radio protocol. The communication range without obstacles is up to 1,100 meters. Runs on pre-installed batteries for up to three years. It can also be powered by a third-party 9-12 V⎓ power supply. 1. LED indicator. Reports the status of WaterStop. 2. Control button. Activates and deactivates the device when the button is pressed for three seconds. When short pressed (for a second), it controls the water supply. 3. Mounting lockers. Supplied in two options: standard (pre-installed) and alternative (anti-sabotage). 4. Holes for installation of a mounting locker. The locker can be installed on any of the four sides of the WaterStop. 5. Mechanical indicator of shutoff valve status: open or closed. 6. Position mark Open. The water is open when the mechanical indicator corresponds to this position. 7. Position mark Closed. The water is shut off when the mechanical indicator corresponds to this position. 8. Lever on the mount. It is designed for manual control of a shutoff valve. 9. Mounting platform. It is installed between the shutoff valve and the electric drive. 10. Removable part of the mount. Allows changing the position of the electric valve by 180° without removing the mount. 11. Bonomi shutoff valve. WaterStop is supplied with a valve in one of three sizes: ½” (DN 15), ¾” (DN 20), or 1″ (DN 25). 12. Tamper button. Reacts to the removal of the electric actuator from the mount. 13. QR code and ID/serial number of the device. It is used to connect WaterStop to the Ajax system. 14. The rotary part of the water shutoff mechanism (electric actuator coupling). 15. Plug for a third-party 9-12 V⎓ power supply connection.
