designed for installation in ceilings up to 20ft
(6.1m) high. An optional pendant-mount
accessory allows the loudspeaker to be hung
from open ceilings.
The loudspeaker shall have a nominal rated
impedance of 8 ohms and shall be wired in par-
allel with a line voltage matching (step-down)
transformer with a selector switch appropriate
for various output taps. The loudspeaker input
connections will allow for direct connection to
either 70V, 100V or low-impedance amplifiers.
Exposed cosmetic surfaces of the loudspeaker
shall be paintable, and the acoustically trans-
parent grille component shall be formed of
powder-coated steel.
Each loudspeaker shall have a bandwidth of
90 Hz – 16 kHz and a maximum continuous
acoustic output of 96 dB-SPL, referenced to a full
bandwidth pink noise input at 1 meter at the
loudspeaker’s rated power. The input connection
shall consist of a three-position barrier connector
with a pre-wired ceramic connector. The loud-
speaker shall meet numerous standards for
combination music and evacuation systems
around the world.
