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.

Figure 32. Securing the redundant safety sling.

• Pass the opposite end of the sling through an external anchor

point or around a structural member and assure that it is

properly secured.

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.
