* With Enclosure Protection Vent - 120 PSI maximum
Without Enclosure Protection Vent - 5 PSI maximum
In order to comply with the NFPA 496 standard requiring
protection against over pressurization of the protected en-
closure, the installer must install one of the following items
in addition to the enclosure protection system.
a) Install a Enclosure Protection Vent on the protected
enclosure.
b) Install a tamper-proof regulator upstream of the
enclosure protection system's system supply inlet to
pre-regulate protective gas supply to 5 PSI max.
In addition, for small, tightly sealed enclosures, or to com-
pensate for a fluctuating protective gas supply, it may
be necessary to pre-regulate the protective gas supply
to a constant 5 PSI regardless of whether an Enclosure
Protection Vent is installed. This will reduce the amount of
"drifting" that can normally occur when maintaining a "Safe"
pressure inside a protected enclosure. The pre-regulation
can be accomplished by installing the TR-10 or TR-10G
Tamper-Proof Regulator accessories or equivalent.
