3.1 Unpacking the Analyzer
Each TAI Model 1220 Combustible Gas Monitoring System is gener-
ally shipped with the channel modules and control module installed.
Since the system is intended as a safety monitor for detecting the
presence of combustible gases in industrial environments, the system
enclosure is normally installed in a safe area, while the remote sensors are
installed at potentially hazardous areas up to 12 thousand feet distant.
Numerous case options are available, however. One optional configuration
involves a purgeable case for installation in hazardous areas. This type of
case, which is maintained under a positive pressure, is purged with com-
bustible-free air.
