The SoundTube CM82-EZ-FS 8" Coaxial In-Ceiling Fire Signaling Speaker incorporates an 8-inch polypropylene driver with a butyl rubber surround in a sealed drawn steel backcan, which allows this speaker to deliver maximum frequency response (65 Hz – 22 kHz, - 10 dB) in an integrated enclosure design.
The CM82-EZ-FS comes with mounting hardware that features a constant-tension, fixed-wing mounting system with a 21-gauge “full-metal” steel tile bridge ensuring rapid and secure installation in any sheetrock or drop-tile application. For easy installation, this series includes a color-coded (green) tile bridge, optional pre-construction bracket, and five-position tap switch for 25-, 70.7- and 100-volt applications.
