Part No. 0009734 Rev. E 07/07
DESCRIPTION
The CIS400 is a complete two-way bass-reflex flush-mount
loudspeaker assembly designed for fixed installations into typical
ceiling plenum spaces. Employing a unique HF waveguide design,
the CIS400 delivers superior dispersion and pattern control over
conventional coaxial designs. The waveguide integrates the
HF driver with a 6.5" LF driver optimized for smooth frequency
response and seamless transition through the crossover point.
The result is extraordinary acoustic performance not generally
associated with a commercial ceiling speaker in this price range.
The CIS400 is supplied fully assembled, complete with a sealed zinc-
coated steel backcan and cam-style installation clamps. The metal
enclosure includes a recessed Euroblock input connector with
detachable mating plug, concealed behind a hinged metal cover
plate. A welded tab is provided for seismic restraint. Two steel T-Bar
support channels are provided to facilitate installation to a standard
tile ceiling. Also supplied is a steel split C-ring, which serves to
disperse the clamping pressure of the mounting cams.
The CIS400 is supplied with an integral 70/100V line transformer
rated to a maximum of 40 watts. Power is adjustable by means of a
recessed rotary switch on the front bezel, and allows selection of 40,
20, 10 and 5 watt taps. A second recessed rotary switch is provided
to engage a 16-Ohm tap for use with low-impedance amplifiers, or
a 150 Hz high-pass filter.
The speaker assembly is shipped with a detachable plastic cover
fitted over the transducers inside the bezel. This protective cover
protects the drivers from damage during installation and also
serves as a paint cover, allowing convenient spray painting to match
interior décor. A powder-coated perforated steel grille is supplied,
and easily installed once the desired Tap Selector and Full-Range/
High-Pass switches have been set.
The entire assembly is fully tested at the time of manufacture and
is warranted to be free from defects in materials and workmanship
for a period of five years from the date of purchase. The speaker
is designed for use in ceiling plenum spaces and meets UL 1480
and UL 2043 regulations governing signaling devices and plenum
applications.
