Kaba’s E-Plex 5900 door lock will monitor opening and closing of 
the door. This is accomplished by installing a position sensor in 
the door, and installing a permanent magnet in the door frame. 
These are shown in the pages that follow.

Installation:

Prepare the door following the E-Plex 5x00 cylindrical lock Installation 
Instructions manual. The door surface will be prepared with a 1" diameter 
recessed area approximately 1" deep, which will accommodate the sensor 
leads to be mounted within the door. The center of this recessed area should 
be 5

the Door and Door Frame Openings illustration below.

For wooden doors, the recessed area must be deep enough to meet the wiring 
path drilled within the door. Do not drill the recessed area completely through 
the door. For metal doors, only drill through the outside of the door. Do not 
drill completely through.

Drill a horizontal hole for the sensor and wires through the edge of the door  
to intersect with the recessed area 5
