Upgrade Von Duprin 22 Exit Devices to Motor-Driven Latch Retraction

The Command Access MLRK1-VD22 is a field-install, motorized latch retraction kit that converts Von Duprin 22 Series exit devices from mechanical to electrified pullback while maintaining UL listings. It hooks directly to the dogging tailpiece and secures with two screws—no rail drilling beyond the wire raceway—making it a fast, clean retrofit. The kit includes Push-to-Set (PTS) fine adjustment, a built-in Request-to-Exit (REX) switch, and the MM5 Smart Module for onboard diagnostics and efficient power management. Backed by a 3-year “no hassle” warranty.

Why installers choose MLRK1-VD22

  • Fast, quiet, smooth & strong motor performance.
  • PTS post-install fine adjustment (≈ 1/4").
  • Built-in REX standard on every unit.
  • MM5 Smart Module with onboard diagnostics and audible feedback.

Installer Notes

  • Confirm device series, handing, and cut length before energizing.
  • Use a regulated 24 VDC supply sized for inrush; verify 24–28 VDC at the rail under load.
  • Route and secure cabling to avoid pinch points in the rail/hinge area.
  • Integrate REX contacts per your access control panel’s input requirements.
