TOWER SYSTEM LCC44/LCC84 WALL INSTALLATION
Redundant safety
If the LCC44 or LCC84 speaker enclosure has been equipped with an
eye bolt for a redundant safety cable (steel wire rope sling or steel chain),
this should be attached to the external anchor before proceeding with the
pan/tilt positioning of the enclosure on the Wall Mount Bracket.
ATTENTION
A redundant safety sling must be anchored to a point higher than the
enclosure and, if possible, to a separate structural member than the
Wall Mount Bracket. If the secondary safety sling must be anchored
using a fastener to the same structural member as the Bracket,
its anchor must be installed at least one speaker-length away from
the anchors holding the Bracket. Use only steel wire ropes or steel
chains that conform to applicable regulations or norms in terms of
construction and Safe Working Load rating. These must be of proper
length and installed in such a position as to prevent the enclosure
from falling more than 20 cm in the case of failure of the Bracket or
the structure to which it is installed.

the eye bolt.
• If using an installed eye bolt, pass one end of the sling through
the eye bolt mounted on the rear of the enclosure.

• Pass the opposite end of the sling through an external anchor
point or around a structural member and assure that it is
properly secured.
Fixing the tilt angle
Once the clevis pin that acts as the pivot axle for the tilt mechanism has
been inserted and secured with the R-clip, you can set the required pan
and tilt angles. It is advisable to set the tilt angle first, as certain pan
angles could obstruct access to the tilt lock bolt. In fact, to allow ample
space for tightening the tilt lock, it is convenient to rotate the entire mount
as far as the mounting surface will allow in pan to the left (as seen from
the front) before setting the tilt angle.
