The NV780MX provides a pre-entry protection solution while keeping the perimeter free from movement, designed to protect exterior/interior walls and doors or windows. NV780M rugged indoor/outdoor detector incorporates two double passive infrared side-by-side detectors (right and left view), independent of each other with separate Active IR Anti-Mask detection for each side. The optics are specially designed to provide multiple narrow beams for excellent detection covering up to 12m (40ft) for each side. Range adjustment is performed by adjusting the viewing angle of the bottom facing beams (moving them up and down). The detectors are configurable to report as a single unit (two side detectors reporting to a single zone output) or as dual units (each side reporting to a separate zone).
