The CW170FR loudspeaker is a highly versatile 6” coaxial system
designed for applications requiring a fire rated ceiling loudspeaker.
Many city and regional authorities are now requiring in-ceiling
systems to be fire rated. To answer this need we offer the
CW170FR, which passes UL 2043 and UL 1480 standards. The
system is enclosed in a 20 gauge steel can that gives it both the fire
rating properties and a proper acoustical enclosure.
The speaker unit is a wide range 6 ½” polypropylene coned coaxial
with a ¾” soft dome tweeter mounting on a pivotable post.
A sophisticated crossover gives smooth and flat response through
the midrange and a slight rise through the highest treble frequencies,
a response suitable for a ceiling speaker. The back can gives full
isolation from the ceiling environment and allows the system to be
bass reflex vented for extended bass response.
A low profile perforated grille with removable scrim allows the system
to be painted any color to further enhance invisibility. Extensive
mounting bracketry is included for easy ceiling mounting in either dry
wall or acoustical tiled ceilings. Four “dog leg” style clamps provide
quick and easy mounting.
A removable steel cover has a clamp suitable for sheathed or
armored cable. Underneath it is a 4 conductor plug with set screw
connections.
A 70Volt/100Volt transformer is built into the system. This allows
multiple speakers to be connected on the same circuit while each
speaker can be set to an individual volume level. The transformer
has a multi-position switch with 3 settings for volume (power
absorbed from the 70/100Volt line) and a 4th position that bypasses
the line transformer entirely.
