5.3 Mounting a reader outdoors (IP55)
To ensure a close fit, mount the reader on a flat surface (mounting surface should not have depths or
deviations of > 1mm).
Seal the cable entry through the base with silicon to avoid ingress of dust, water, and draft. Endure that
there is no silicon between the wall and the base, remove residue sealant if necessary.
To attach the base to a surface:
1. Peel the backing paper from the foam.
2. Stick the foam firmly to the back of the base.
3. Make a small hole in the backing of the base (item 1 in the diagram below). Use this hole to feed the
cable through the base and into the reader base.
4. Remove any fabric around the cable entry point on the back of the reader to avoid water channeling
to the inside of the reader.
5. Attach the base to the wall with three screws: one in the middle at the top of the base, and one in
each of the corners at the bottom of the base.
1 Cable entry through base
2 Tamper screw
3 Tamper base
4 Self-adhesive foam base
6. If additional wall removal tamper protection is required, fix the screw (item 2) into the tamper base
(item 3). Do not over-tighten the screw as this can damage the tamper base.
7. Continue to follow the instructions detailed in Connecting the cables on page17.
The reader is automatically tamper protected when removing the front of the reader from the reader
base with the help of the opening tool. The wall removal tamper is an additional protection against
physical attacks.
