5.1 Pre-installation Considerations
- Locate Mounting Holes: If the lock panel is installed in one piece with the lock box, first locate the mounting holes.
- Door Inset: For door insets, the latch needs to be flush or slightly indented at the edge of the door panel.
- Door Cover: For door covers, the latch needs to be indented one more side panel thickness.
- Marking Holes: Re-mark the mounting hole locations on your furniture.
- Drill Holes: Combine with the provided opening size drawing to drill necessary holes in the door panel.
5.2 Connecting and Securing the Lock
- Connect Wires: Pass the wires from the keypad panel through the center hole of the door.
- Connect Lock Box: Connect the lock box to the keypad panel. Ensure the side with 4 metal dots faces out.
- Secure Lock Box: Secure the lock box with the lock panel using the long screws provided.
- Mount Latch: Position the latch mounting height. For door inserts, go in one door panel thickness deeper. For door outer covers, mount the latch directly against the edge of the side panel. Ensure the distance between the latch and the side of the door remains unchanged.
- Screw Latch: Screw the latch into place.
