(includes batting (includes batting) (for UL fire
protective speakers)
Description
Lowell CP8 Series protective backboxes with extended grille
mounting flange are designed for recessed installation of distributed 8" speaker systems. Extended flange makes them
ideal for use in new construction where the flange protects
the opening from plaster, poured concrete, or sheetrock. The
series may also be used in new or existing construction
when installed into suspended tile ceilings. Choose from
three depths to meet installation and acoustic requirements.
Model ULCP84 is 4”D and is part of UL 1480 5th Edition Listed Fire
Protective Signaling Speaker Series ULD and ULS.
Series CP8 backboxes are fabricated of welded, unitized heavy
gauge steel and are sufficiently undercoated to eliminate
acoustic and metallic resonance. Models CP84 and ULCP84 are
4”D with a foam pad. Models CP7 and CP810 are 7”D and 10”D
respectively and are lined with 1-1/2" thick premium acoustic lining having a density rating of 1-1/2 pounds to absorb undesirable resonance in the high frequency range. Additional cubic volume of these models also allows the 8" speaker to operate at a
more optimum loading level providing the system with improved
low frequency response. As noted in the chart below, some
models may additionally be used with 6.5” speakers and
Lowell’s Unihorn Model LUH-15T.
Each unit is furnished with four combination 1/2" - 3/4" conduit
knockouts and four 1/2" wire knockouts. The grille mounting
flange projects 0.437" for efficient installation in plaster, poured
concrete, sheetrock, or suspended tile ceilings. The flange
includes 8-32 screw retaining U-clips to accept a wide variety of
Lowell 8" speaker grilles - see chart below (order separately).
When installed in a suspended tile ceiling, tile bridge Model
LBS8-CP or SS Series rails are recommended to transfer the
assembly weight to the ceiling grid. The backbox is finished in
Lowell's durable black powder epoxy.
