Von Duprin Quiet Electric Latch (QEL)

Traditional electronic latch retraction utilizes magnetic solenoids that require a high voltage inrush. When activated, the retraction of the solenoid results in a loud and abrupt sound. Motor driven latch retraction is more efficient and provides a much quieter solution with less of a disturbance.

• Lower amperage requirements allow the QEL option to work with any new or existing Von Duprin or Schlage Power Supply
• On-Board diagnostics provide visual indication if the system is installed incorrectly or encounters a user error
• Automatically calibrates for specific openings and removes the adjustments required to the dogging rod
• Option on all 98/99, 33A/35A, and 94/95 Series Exit Devices (Note: Retrofit kits are available to upgrade existing mechanical or electronic latch (EL) devices.)
