Upgrade Corbin Russwin ED4000/ED5000 & Accentra/Yale 7000 to Motor-Driven Latch Retraction

The Command Access MLRK1-COR converts Corbin Russwin ED4000/ED5000 and Accentra (formerly Yale) 7000 Series exit devices from mechanical to electrified pullback while maintaining listings. The kit retracts the latch and pushpad for electronic dogging and includes Push-to-Set (PTS) fine adjustment plus the MM4S Smart Module for onboard diagnostics. UL Listed and backed by a 3-year “no hassle” warranty.

Installer Notes

  • Verify device series/handing and rail cut length before energizing.
  • Use a regulated 24 VDC supply sized for inrush; confirm 24–28 VDC at the rail under load.
  • Route cabling to avoid pinch points; secure the raceway and strain relief.
  • Centralize the power supply near the access control panel when beneficial.
  • Integrate the optional REX contacts per your panel’s input requirements.
