The LD9875L-US4-3-LHR is a Von Duprin 9875 Series Mortise Lock exit device with Latch Detector (LD) and Lever trim in Satin Brass, sized for 3 Foot doors. Lever Trim — Night Latch function. Outside lever locked/unlocked by key, always free from inside. Ships less cylinder — order a mortise cylinder separately to match your existing keyway.
Latch Detector — monitors the latch bolt position and reports status to the access control panel. 24VDC. ANSI/BHMA A156.3 Grade 1 certified. Hex key dogging standard. Field reversible handing.
Pro-Tip from Our Locksmiths: Latch Detector on a lever trim exit device is the most common setup for access-controlled corridors — the panel knows the door is latched, and you get full key override on the outside. Make sure the LD wiring runs back to a supervised input on your access panel for proper door status reporting.
