Installation
The AA-04 is designed to be permanently attached to a wall or other fixed vertical
surface.
Positioning
The AA-04 should be mounted in a convenient position for use and wiring.
During installation, wired connections will need to be made and allowance should be
made for the installation of electrical conduit or trunking if required to make entry to
the unit.
Ideally the AA-04 should be attached directly to the wall with the cables being fed
from within the wall. For hollow walls this should be straightforward. For solid walls it
may be easiest and neatest to feed the cables right through the wall from the other
side.
Alternatively the AA-04 may be attached to a round conduit box which may be buried
or surface-mounted, though this last option will result in the unit projecting further
from the wall, making it less stable and more vulnerable.
It is recommended that there must be a flat unobstructed area of wall extending at
least 70mm above and 110mm below the mounting centre to allow fitment and
removal.
If a Lasermet Miniature Warning Sign is being fitted above the AA-04 the centres
should be at least 140mm apart vertically.
Refer to Figure 6 for details of the fixing holes and cable entry. The wallplate and
locking plate are secured using preferably four screws on a 35.4mm square around
the cable entry point. The locking plate and plastic wallplate disk are pre-drilled and
may be used as a marking template. If using a round conduit box, the holes will align
with the cover fixing holes.
Once all the holes have been made, secure the wallplate and the locking plate as
shown in figure 6 with the plastic wallplate against the wall. Check that the plastic
wallplate and locking plate are aligned as shown.
Feed the cables through the hole in the centre of the locking plate.
NOTE:
Make the electrical connections before attaching the unit to the wallplate, see
the Wiring section.
