Miller Edge Patriot2 MIR-Z2 is a photo-eye sensing edge that attaches directly to a rolling steel or roll up door. The photo eyes travel below the door during the closing cycle. Unlike traditional status mount photo eyes, Patriot travels with the door to sense obstructions and reverse movement of the door prior to contact. This non-contact system consists of thru beam photo optics. Emitting and receiving eyes mount to flexible molded Z-Flap mounting housings. The Z-Flaps are mounted to the bottom of the door and extend below the leading edge of the door, providing an invisible infrared light beam of protection. If the beam is blocked, Patriot signals the door operator to stop and/or reverse. Patriot2 monitored models (MIRM-Z2) may be used to comply with current UL325 requirements. Also available in a fail safe wiring configuration. (MIRF-Z2).
