Von Duprin RX-QEL-99-EO-626-4 Exit Device

Product Description

The VON DUPRIN RX-QEL-99-EO-626-4 is a rim-style exit device designed for commercial door applications requiring controlled egress. Built within the 99 Series product family, this unit incorporates a Request-to-Exit (RX) function alongside a Quiet Electronic Latch retraction (QEL) mechanism, making it well suited for access-controlled openings where audible latch noise must be minimized. The EO (exit only) trim configuration and 626 satin chrome finish round out this assembly as a professional-grade hardware solution. Installation is performed by licensed door hardware specialists or commercial locksmiths working to applicable building and life-safety codes.

This exit device is intended for commercial and institutional applications such as office buildings, schools, healthcare facilities, and other occupancies subject to IBC egress requirements. The RX feature allows the device to signal an access control system when the door is pushed, supporting integration with electronic access control panels. The QEL function enables the latch to retract quietly via an electrical signal, allowing hands-free or card-reader-triggered entry from the secure side without mechanical noise associated with standard motorized latch retraction.

Compatibility

Installation Notes

Installation should be performed by a qualified door hardware technician or commercial locksmith familiar with ANSI-grade exit device mounting and low-voltage wiring practices. Disconnect all electrical power to the access control panel and the door hardware circuit before making or modifying any wiring connections. Verify door and frame preparation dimensions and handing prior to mounting to avoid field modifications. All egress hardware installations must comply with applicable IBC, NFPA 101, and local authority-having-jurisdiction requirements.
