Provide panic egress hardware for a 36 inch door opening while adding two electrical functions used at controlled access points. The rim-mounted configuration carries a request-to-exit function and electric latch retraction, allowing the exit device to participate in door-control and monitoring arrangements without changing its primary egress role. The 630 finish designation supports finish matching where that code is required for the opening. Request-to-exit operation gives connected door-control equipment an event signal when the exit device is actuated. Electric latch retraction provides an electrically controlled means of retracting the latch, supporting scheduled or authorized release arrangements at the opening. These functions make the device relevant where mechanical egress hardware must interface with access-control equipment rather than operate as a standalone panic bar. Security Door Controls S6103PU36REEK combines the 36 inch rim panic format with both REX and ELR functions. That combination distinguishes it from basic mechanical rim hardware by addressing the signaling and electrical-release requirements at the same door. Verify the door width, handing requirements, frame and strike arrangement, and control-system wiring method before selecting exit hardware for an opening.
