1.12 Mounting the Unit (all models)
Select a suitable position to mount the unit, which satisfies the following criteria:
Highly prominent for maximum deterrence
Additional shelter (e.g. under the eaves) is an advantage
High enough to be out of normal reach to deter tampering
Safe ladder access
Good cable access
In addition to the two adjustable screw fixing points, the unit also has a central
keyhole & spirit level to simplify mounting and aid levelling.
Three screws and wall plugs are required for mounting the backplate to an even
surface. An additional screw may be required to adjust the wall tamper by fitting
through the screw hole next to the dual tamper microswitch. In doing so, care must
be taken to leave the screw head slightly proud to ensure that the microswitch
remains level and closes correctly when the inner cover is fitted.
N For maximum weatherproofing the unit should be flat to the wall.
1.13 Spirit Level
All units come with an integral spirit level to aid installation, the spirit level may be
mounted vertically or horizontally in the backplate. By default the level will be
mounted horizontally.
