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 TM 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.
