The LD98NL-US28-3 is a Von Duprin 98 Series Rim exit device with Latch Detector (LD) and Night Latch trim in Aluminum, sized for 3 Foot doors. Night Latch — outside knob 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: Night Latch with Latch Detector is the go-to for schools — the teacher can lock/unlock from outside, and the access panel monitors latch status for lockdown verification. The LD switch is factory-installed and wired to a pigtail for easy connection during rough-in.
