Product information

Description

Ajax WaterStop Wireless combines a high‑quality ball‑valve actuator with RF wireless communication to automatically shut off water within seconds when a leak is detected. Designed for integration with an Ajax security system, WaterStop works with Ajax LeaksProtect and compatible third‑party detectors to stop water flow remotely via the Ajax apps or automatically by scenario. The device is battery powered with an option for an external 9–12 V⎓ supply, fits common valve sizes, and supports secure two‑way radio communication over the Jeweller protocol.

Advantages

WaterStop closes the water supply in about 5 seconds using a powerful electric actuator (up to 8.5 N·m torque), limiting leak volume even under typical pressure. It supports ½", ¾" and 1" valve sizes (DN 15, DN 20, DN 25) and is compatible with ISO 5211 flanges, allowing installers to use market‑available ball valves. The unit is wireless and battery‑powered (replaceable CR123A cells), offers an optional external 9–12 V⎓ input for continuous operation, and provides overheating and overcurrent protection for reliable actuator performance. Secure, long‑range Jeweller radio ensures stable communication, while system features like ReX extenders, in‑app control, detailed event logs and remote configuration simplify installation, monitoring and maintenance.

Suitable for

  • Residential apartments and houses
  • Small commercial premises and offices
  • Basements, storage rooms and technical spaces
  • Properties requiring remote water shutoff and automation

Key specifications

  • Wireless frequency: 866–922 MHz (Jeweller protocol)
  • Actuator torque: up to 8.5 N·m
  • Valve compatibility: ISO 5211; available sizes ½" (DN15), ¾" (DN20), 1" (DN25)
  • Power supply: replaceable batteries (CR123A), 3‑year typical battery life; optional external 9–12 V⎓ input
  • Dimensions (actuator unit): 70 mm × 104 mm × 140 mm
  • Event log capacity: 500 recent events
  • Range (open space): up to 1,100 m (depending on environment)

How to use

Install a compatible ball valve in line with the existing plumbing and mount the WaterStop actuator on the valve’s ISO 5211 flange in one of four possible orientations. Insert the replaceable batteries or connect an optional 9–12 V⎓ power supply if continuous operation is required. Add WaterStop to the Ajax hub using the Ajax app, configure scenarios or automatic reactions to LeaksProtect or third‑party detectors, and test the system. From the app you can remotely check status, close or open the valve and receive notifications about events or low battery.

Usage recommendations

For reliable operation, use compatible ISO 5211 ball valves of the specified sizes and replace batteries every three years or sooner if the app notifies low charge; consider connecting an external 9–12 V⎓ supply in locations with extreme temperatures or where frequent actuator use is expected. Use ReX extenders when installing in locations with complex radio conditions to ensure stable communication.
