Mounting
You should mount the keypad where it is
accessible to designated points of entry
and exit. Once you have selected a dry
and secure location, perform the follow-
ing steps to mount the keypad.

Remove the keypad backplate by
loosening the screw (optional) located
at the base of the unit.

Secure the keypad backplate to the
wall in the desired location. Use the
screws provided.

To use the keypad tamper, insert the
tamper switch supplied into the opening
located in the centre of the backplate.

For tamper use, try to ensure the back-
plate is mounted on a smooth, flat sur-
face. If mounting on a rough surface,
fasten the enclosed surface tape to
the wall to even out the surface area
where the tamper will be positioned.

Before attaching the keypad to its
backplate, complete the keypad wir-
ing as described in the next section.
