APPLICATIONS
Atlas Sound clock/speaker baffles provide convenient and cost-effective installation of analog clocks and 8" dia. loudspeakers for use in schools, offices,
commercial, industrial, and institutional applications of all kinds. CRS construction in surface and recessed styles and with optional panel control inserts
assure service durability and application flexibility.
830 Series. Economical clock/loudspeaker baffle assemblies are offered in two
sizes and feature a CRS grille and trim ring mounted to an 18-gauge CRS panel
with cutouts for mounting an 8" dia. loudspeaker (order separately). The 830
Series mounts into position using a double-action torsion spring system to provide a hardware-free appearance. Models include a black gasket for concealed
mounting of an 8" dia. (203mm) loudspeaker and a universal clock mounting
bracket for installation of almost any 9", 10", or 12" dia. analog clock (by others).
The panel, grille, and trim ring components are finished in a white epoxy.
Assemblies can be recessed or surface mounted using 194 Series enclosures
(see page 3).
840 Series. Contemporary clock/loudspeaker baffle combinations are offered in
two sizes and feature a one-piece 18-gauge CRS frame with a 22-gauge CRS
perforated grille, a subplate for mounting an 8" loudspeaker (order separately),
and a universal bracket for mounting a 9", 10", or 12" clock (by others). The
separate subplate is designed for easy concealed installation of a standard 8"
dia. (203mm) loudspeaker (order separately). Loudspeaker grille and frame are
finished in textured white epoxy. Assemblies can be recessed or surface mounted using 195 Series enclosures (see page 3).
Model NC850. Top of the line clock/loudspeaker baffle/with classroom control
panel uniquely and attractively combines multiple functions into one convenient
assembly. The multi-purpose "classroom nerve center" has provisions for
mounting an 8" dia. loudspeaker, a 9", 10", or 12" dia. analog clock, and a variety of switches and controls (by others).
The assembly's front-panel door features concealed hardware with a full-length
piano hinge for easy access to the components and a lock to deter tampering.
The top section includes a universal clock mounting bracket. The center section
features a loudspeaker subplate with weld studs for concealed speaker installation. The bottom section features (2) 4"W x 6"H openings and (1) one 7
1
⁄2"W x
6"H opening (center) for mounting standard switches and controls. Atlas Sound
offers blank and precut plates with #4 weld studs for contractors to mix, match,
and rear-mount standard switch components (order panels separately - switch
components by others).
Assembly frame is made of 20-gauge CRS and finished in black epoxy. The
speaker panel is 22-gauge perforated CRS with
1
⁄16" (2mm) holes on 3⁄32" (2mm)
staggered centers. The panel is finished in a textured white epoxy and recess
mounts to enclosure Model E850 (see page 3).
