Optex LRP100QS detector has changed the industrys perception of using passive infrared in outdoor applications. It is simple to install and align and reliable in operation. The use of four elements in a 100 metre detector is unique and underlines our continued commitment to development. Newly equipped double conductive shielding helps reduce false alarms by card headlights and reflected sunlight. Redwall detectors feature an advanced visual alignment system pictured below. At installation, a small reflex viewer, supplied with each detector, can be plugged into the sensors front window and provides a view of the area to be protected. This method allows simple and quick alignment of the Redwall detector.
