DoorProtect U Jeweller is a version of Ajax’s well-known opening detector, refined to meet the strict UK standards. It delivers reliable protection wherever break-ins may occur — whether it’s doors, windows, or safes holding valuables. Its dual reed switches ensure accurate detection of unauthorized openings, while the anti-chatter technology minimizes false alarms. Two magnets of different sizes allow for adapting the detector installation to various door and window designs.
