The Superior DoorProtect Plus (Code: 133198.21.WH1) is not a simple magnetic contact. It belongs to the professional Superior series by Ajax, featuring Grade 2 certification, and is designed for installations where security cannot be compromised.
The "Plus" version incorporates an advanced accelerometer, allowing the device to detect vibrations (attempted break-ins or tampering) and changes in tilt angle. This makes it an ideal solution for windows that remain tilted, as it can protect the area while allowing ventilation.
