Black Lens for Ajax Motion Detector

Black Fresnel Replacement Lens for Ajax Motion Detectors

The Ajax AJ-MOTIONPROTECT-B-LENS is an original black Fresnel replacement lens designed to replace the front optical cover of compatible detectors when it becomes damaged, scratched or worn. It allows this essential component to be restored without having to replace the complete detector.

The Fresnel lens plays a direct role in how the PIR sensor receives infrared radiation. A damaged lens can affect the correct reception of this radiation and compromise motion detection. This replacement is compatible with AJ-MOTIONPROTECT-B, AJ-MOTIONPROTECTPLUS-B, AJ-COMBIPROTECT-B, AJ-MOTIONCAM-B and AJ-MOTIONCAM-PHOD-B.

This product is specifically a replacement part for existing installations, not a detector intended for new installations. It is particularly useful for installers servicing Ajax alarm systems, as the front lens can be replaced while retaining the existing device when the rest of the detector remains in good working condition.

In short, the Ajax AJ-MOTIONPROTECT-B-LENS provides a practical solution for repairing compatible black Ajax detectors with a damaged front optical lens. For maintenance, replacement or system expansion projects, you can also browse our range of security detectors and sensors.
