General Information
The assembly described in this manual is a speaker/amplifier housed in an explosion-proof cast aluminum
enclosure equipped with a handset. 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
noise areas where explosive atmospheres exist or may exist. The Model 780-301 Single Party Handset
Station and Model 7805-301 Multi-party Handset Station are BASEEFA approved to CENELEC
Standards Ex dib for Zone 1 Group IIC T5.
