Introduction

The assembly described in this manual is a speaker amplifier housed in an explosion-proof cast

aluminum enclosure. The assembly is designed to be installed in hazardous areas where combustible

gases exist or may exist. The 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 flame-path opening that cools the exiting gases to

a temperature below the flash point of the external, explosive atmosphere.

Application

The hazardous area Page/Party

speaker amplifier provides clear, page broadcast communications even

in high noise areas where explosive atmospheres exist or may exist.

The Model 670-301 Speaker Amplifier is BASEEFA approved to CENELEC Standards Ex dib for Zone

1 Group IIC T5.

HARDWARE CONFIGURATION

The explosion-proof cast aluminum enclosure has a bolted-on cover with an epoxy coating. There are no

external operator controls. See Figure 1. The Model 751-001 Speaker Amplifier is housed inside the

enclosure.
