The Vulcain 301EM Expansion Module
acts as a controller for up to four remote
refrigerant sensors and suits a variety of
gas detection system solutions.
Easily configured to meet ASHRAE 15, B-52 and
International Mechanical Code requirements, the
301EM is commonly used to optimize gas detection
in mechanical and chiller rooms. A full complement
of sensors (including toxic, oxygen, combustible
gases and a full line of refrigerant sensors), horns,
strobes and remote panels provide added flexibility
to suit a variety of gas detection system solutions.
ASHRAE No 15-2001 Mechanical Standard and
B-52 Code Compliance
The ASHRAE and B-52 security standards have
been established to minimize risk and protect
the safety of mechanical room personnel and
the environment at large. Available in a special
configuration, the 301EM mechanical room
controller has been carefully designed to meet
and even exceed these rigorous standards. The
Vulcain 301EM can be configured to offer automatic
fan, horn and strobe activation in addition to
manual fan activation. Latching relay for manual
alarm recognition, silence key for manual horn
deactivation, built-in 24 Vdc outputs for horn
operation, and 2 breakglass switch accessories
for manual alarm activation ensure optimal
performance.
