Mounting - General
Mounting of the Amplified Recessed Speakers is
accomplished utilizing a mounting ring or backbox.
The V-1011BB and the V-1012BB are equipped with
backboxes and support rails, while the V-1011MR
and the V-1012MR are supplied with mounting rings
and support rails. See Figures 3 and 4.
Mounting Rings and Backboxes:
•
Provide support to prevent ceiling tile from
sagging from the weight of the speaker
•
Provide receptacles for torsion spring installation
•
Mounting rings are constructed of 20 gauge cold
rolled steel with a rust preventative coating
•
Backboxes are constructed of 22 gauge cold
rolled steel, undercoated to prevent mechanical
and acoustical resonance and finished in a rust
preventative coating
•
Backboxes meet most local fire codes for use in
air plenum return ceilings
•
Backboxes provide acoustic enclosure behind the
speaker for improved sound quality
•
Rails are used with both the mounting rings and
the backboxes and are finished in a galvanized
coating
Mounting Procedure
•
Determine desired speaker location. The speaker
should be located in the center of the ceiling tile
•
Use the mounting ring or backbox as a template,
cut a hole in the tile -
- 6 1/2" diameter hole for the 4" speaker
- 10" diameter hole for the 8" speaker
•
If the backbox is to be used, run the cable
through one of the four knockouts on the
backbox and connect the wires to the speaker as
described in the Installation and Connecting
Arrangement to 25 or 70V Paging System
•
Place the backbox or mounting ring above the
ceiling tile. Place speaker through the tile.
Compress springs into the slots provided in the
backbox or mounting rings. Press speaker to the
tile. The torsion springs should pull the speaker
to the tile.
•
The backbox rails sit on top of the "T" bar of the
ceiling bridge (see Figure 3). The mounting ring
rails lay on the tile to give it support (see Figure
4). The height of these bars can be adjusted by
loosening the wing nuts. Attach rails to the
backbox by placing rails through the slot
provided on the backbox and securing to the
backbox with a wing nut.
