Ajax LeaksProtect Jeweller
Wireless water leak detector
Constant control. Instant notifications.
LeaksProtect Jeweller monitors for leaks 24/7 and notifies of an issue before it escalates into damage. Compact enough to fit almost anywhere, the device protects vulnerable areas, including hard-to-reach places. If a washing machine leaks or a pipe bursts, the detector instantly reports the incident and can trigger Ajax WaterStop Jeweller to automatically shut off the water supply. The detector requires no mounting and works for years without maintenance.
Effective minimalism
Sleek and simple on the outside, LeaksProtect Jeweller delivers reliable protection. With contact pairs on all four sides, the device detects water from any direction and instantly reports a leak. Once the contacts dry out and open, the detector notifies users that the leak has stopped.
- Up to 5 years of operation on pre-installed batteries
- 24/7 protection
- IP65-rated enclosure
Precise reporting at any scale
LeaksProtect Jeweller enables swift response in both small apartments and industrial-scale sites. When a leak occurs, Ajax apps provide detailed notifications with the device name, time, and exact location. This helps guide plumbers directly to the affected area without wasting time on investigation.
- Up to 250 detectors in a single Ajax system
- In-app notification with incident details
Advanced automation for greater safety
LeaksProtect Jeweller is part of the Ajax ecosystem and can interact with other devices through automation scenarios. With these scenarios, the detector can trigger water shutoff before a leak causes damage. To proactively reduce risks, the water supply can also be set to turn off automatically when not in use — a reliable combination of security and automation that runs like clockwork
