Overview
Upgrade mechanical exit hardware to modern access control without replacing the entire device. The Security Door Controls QuietDuo LR100VDK latch retraction kit converts Von Duprin exit devices into electrically controlled, quiet dogging/latch-retract solutions ideal for commercial, institutional, and healthcare applications. Designed for 36–48" openings and compatible with Von Duprin models such as 98 and 99, the LR100VDK provides seamless retrofit capability that preserves code-compliant egress while enabling integration with access control, building automation, or monitoring systems.
With 24V DC power (700 mA inrush, 200 mA continuous), the kit balances low-voltage efficiency and robust performance—reducing door noise and wear by depressing the pushpad electrically and retracting the latch for momentary or sustained operation. The unit’s automatic re-trigger improves reliability in heavy-use openings and eliminates the need for a door sequencer on pairs of manual doors when powered appropriately. Ideal for security-conscious facilities deploying surveillance, access control, and building monitoring, the LR100VDK streamlines installation and minimizes downtime. Contact your supplier or add the LR100VDK to your next security upgrade to modernize exit devices while maintaining life-safety compliance.
