Description
The Von Duprin 967240 US28 is an electronically controlled exit device designed for educational and institutional settings that require rapid lockdown capability. When activated via thumb turn or cylinder key, the ESL lockdown option interrupts power to the QEL motor, electronically extending the latchbolt to secure the door's pull side while signaling the access control system. A visual indicator on the mechanism case cover confirms secure lockdown mode.
This device is compatible with Von Duprin 98/99 and 33A/35A series exit devices equipped with QEL latch retraction and meets fire and life safety codes for free egress. Modular conversion kits enable quick upgrading of existing devices. For compatibility verification, installation guidance, or to discuss your lockdown security needs, contact our authorized dealer experts at sales@edlocks.com or call 1-877-207-6067.
