Scantronic recommend that you mount the keypad as follows:
1.
Select which cable entry you are going to use and break out the
appropriate plastic sections.
2.
Hold the backplate in place against the wall and mark the position of
the centre hole in the adjustable cam (see Figure 5).
3.
Drill and plug the hole, and screw the backplate to the wall through the
adjustable cam. Do not tighten the screw completely home.
4.
Make sure the backplate is level and mark, drill and plug at least two
other fixing holes. Screw the backplate to the wall through the fixing
holes.
5.
Cut the plastic webs connecting the cam to the remainder of the base
plate.
Note: If you do not cut the webs then the tamper switch will not operate if the
complete keypad is forced off the wall.
6.
Mount the front of the keypad (containing the keypad pcb) onto the
backplate and make sure that the tamper switch operates.
7.
If the tamper switch does not operate then rotate the cam until the
tamper switch operates correctly when the front of the keypad is
mounted on the backplate.
