Introduction
The assembly described in this manual is an explosion-proof enclosure and intelligent speaker amplifier
designed to be installed in hazardous areas where combustible gases exist or may exist. The extra thick
cast aluminum enclosure, while not gas tight, is designed to withstand repeated internal explosions
without expelling gases hot enough to ignite the external atmosphere. This is accomplished through the
use of a precision-machined enclosure opening flame path that cools the exiting gases to a temperature
below the flash point of the external, explosive atmosphere.
How to Use the Assembly/Model

The hazardous area SmartSeries amplifier is designed to provide clear communications even in high noise
areas where explosive atmospheres exist or may exist.
