How does the Von Duprin 98/99 rim or vertical rod exit device with lever trim convert from L to L-NL function?

To convert the Von Duprin 98/99 Rim or Vertical (Rod or Cable) Exit Device with functional lever (996L-R/V) to act like a rigid lever (996L-NL-R/V) with key over ride follow these steps:

  1. Remove the NL screw from the cam located on the back of the center case of the 98/99 exit device.
  2. Rotate the cam with screw driver clockwise or counter clockwise until the slider on the back of center case moves to the down position. 
  3. Reinstall the NL screw back into the cam assembly.  
 
The 98/9975 Mortise Device cannot be setup to provide NL function from a 996L-M trim, you must have the rigid lever 996L-NL-M trim on that device.
