The McGuard is a wall-mounted presence detector designed for installation in switch boxes. It is ideally used in small spaces such as offices, apartments, hallways, and stairwells. The elegant, aesthetically pleasing housing with an integrated lens and invisible buttons prevents unauthorized adjustments to the settings. Superior lens patterns and well-distributed as well as concentrated detection beams provide high sensitivity. In addition to PIR detection, the detector can also be activated by sound. The ambient light can be adjusted for flexible application. Three different operating modes are available: Manual ON, AUTO, and Manual OFF. Additionally, the detector can be controlled with a push button. The decorative frame of 50 x 50 mm fits into most European standard switch programs.
