RCI DE8310SX28 Delayed Egress Lock with Built-In Sounder

Control exit release at a secured opening while providing an audible local indication with a delayed-egress device that includes its own sounder. RCI DE8310SX28 combines delayed egress operation and a built-in sounder in one physical-security hardware assembly. It fits door locations where release should not occur immediately after an exit request and where nearby personnel need audible indication at the opening. Delayed egress addresses an exit-control use case rather than ordinary passage control. The integrated sounder keeps audible notification at the device, avoiding a separate sounder solely to provide local indication. This distinction matters at perimeter doors, controlled interior boundaries, and other openings where the release sequence is part of the security design. Installation requirements and door behavior must be established for the specific opening. Choose this unit when the requirement specifically calls for delayed egress with a built-in sounder rather than a locking component or audible device alone. Its identified capabilities support controlled exit openings that need both delayed release behavior and local audible output. Keep the product role clear during design: it is security door hardware for an exit opening, not a general-purpose sounder. Determine mechanical fit, electrical connections, and site requirements before installation.
