SDC Electric Latch Retraction Kit for Von Duprin 33/35 and 98/99 Devices, LR100VDK

Compatible with the following models / series of Von Duprin Exit Devices:

  • Rim - 98/99 Series & 33/35 Series
  • Surface Vertical Rod -  9827/9927 Series & 3327/3527 Series
  • Concealed Vertical Rod - 9847/9947 Series & 3348A/3548A Series
  • Mortise - 9875/9975 Series
  • Three Point Latching -  9857/9957 Series

The SDC LR100 Series Electric Latch Retraction Kit enables electric access control and dogging of mechanical exit devices. When energized the motor retracts the exit device latch and pulls the pushpad into the dogged (depressed) position enabling momentary or sustained push and pull operation of the door. The latch retraction mechanism may be activated by an access control, remote control device or building automation system. The exit device always provides uninhibited egress.

Field Installed Retrofit Kits:

  • UL Classified for use with 3hr fire rated & non-fire rated exit devices


  • Low 700 mA Inrush, 200 mA Continuous @ 24VDC
  • For access control and sustained dogging applications
  • Simultaneous latch retraction and dogging (pushpad depressed*) for most exit devices
  • Pushpad is depressed* electrically for quieter push / pull operation
  • Automatic re-trigger if device does not pull on first try

*** IMPORTANT NOTE: Electric pushpad depression not available with Corbin Russwin, Yale, Adams Rite and Sargent. Meaning it only retracts the latch, as opposed to pulling/ drawing the push bar in while retracting the latch simultaneously. ***


  • Eliminates need for costly replacement of existing exit device
  • Significantly less labor and costs compared to competitive retrofit kits
  • Eliminates need for costly power supplies with high inrush circuitry. Compatible with UL Listed Access Control Power Supply
  • Only 1 Amp power supply required for up to 2 exit devices
  • Low current enables longer wire runs with smaller gauge wire
  • No door sequencers required for pairs of manual doors
  • Installs in Von Duprin non-fire rated panic device without removing from the door

Optional Status Kits:

  • Latch Status Kit - 98/99 Series - #LRVD1L
  • Latch Status Kit - 33/35 Series - #LRVD2L
  • Pushpad/Dogging Status or REX (Request to Exit) Status Kit - 33/35 & 98/99 Series - #LRVD1R
