Exidor Outer Access Device (OAD) Installation Video

All Latham’s, fire exit doors are manufactured with a flush exterior. If you also wish to use your fire exit as an entrance, you will need to install a compatible Exidor Outer Access Device (OAD).

Latham’s offers a range of outer access devices, providing you with different options to suit your needs. From standard to high security, and even code locks

To start fitting your OAD, detach the push bar mechanism and shoot bolt rods by removing the screws. Refit the Panic bar packer to use as a template, then use the pre-drilled holes as a guide to drill through. Drill through the door using a 7mm drill bit for the fixing holes, and an 18mm drill bit or step drill bit for the spindle hole.

We would also recommend drilling through the holes through the outside of the door skin. Depending on which OAD and door fitment, you will also need to cut the OAD spindle and fixing screws to suit using the following measurements (see video).

Fit the lever handle to the OAD by tightening the grub screw with the Allen key provided.

On the exterior side, fix the OAD to the door using the fixings provided. The screw heads need to be flush with the door, so as not to lift off the Panic bar mechanism when fitted over the top.

If you need to change the orientation of your OAD, pull the lever handle all the way down, the drive spindle will then rotate. Using the square spindle in the box, turn the spindle into the required position until it stops. Release the lever handle, then rotate the drive spindle until the notch lines up with the mark on the backplate. Your orientation is now set. Insert the spindle through the door then refit the Panic bar.

The outer access devices rely on the keys to activate and deactivate the spindle from the Panic bar. Insert and turn the key clockwise through one complete revolution to lock the door. Turn the key back anticlockwise through one complete revolution to engage the outer access device, and open the door.
