Ajax LeaksProtect detector: H24 protection from Water Leaks
The LeaksProtect Jeweller detects the first signs of water at its location, thanks to four pairs of sensitive contacts positioned on all sides. In case of simultaneous contact with water, the alarm is sent to the hub in less than 0.15 seconds.
The detector notifies both the beginning and the end of flooding, enabling rapid emergency management.
Integration with WaterStop solenoid valve (52271)
Combined with the Ajax WaterStop valve, the LeaksProtect allows automatic or manual management of water shut-off via apps or automatic scenarios, creating a smart, integrated anti-flooding system.
Operation against leaks and major flooding
Effective minimalism
Wherever water comes from, the detector will immediately activate the alarm. Contact pairs are located on the four edges of the LeaksProtect housing. If at least one of them comes into contact with water, the detector signals a leak. And when the contacts dry out, it notifies the end of the leak.
- Up to 5 years without battery replacement
- Works 24/7
- IP65 housing protection
Against small leaks and large floods
LeaksProtect detectors can protect both small apartments and commercial centers/industrial complexes from flooding. In case of an incident, informative notifications will let you know where to send plumbers.
- Up to 200 detectors in the system
- Detector location name and room in the notification.
