7.2.2 Heptauoropropane Automatic Fire Extinguisher
When the FusionDC1000 catches re, a lot of smoke is generated and the
temperature rises sharply. The smoke detector and heat detector send
re alarm
signals to the extinguishant control panel, which generates an electrical actuator
start voltage to start the electrical actuator of the re cylinder. Then the re
cylinder valve is opened, and extinguishant is released into the protected zone.
Heptauoropropane (HFC-227ea) is a colorless, odorless, non-conductive, and
secondary pollution-free gas extinguishant. It features cleanness, low toxicity,
good electrical insulation, high
re extinguishing eciency, zero threat to the
ozonosphere (ODP = 0), and short residual time (ATL = 34Y).
The design and construction of the
Heptauropropane re extinguisher comply
with BS ISO 14520-2006 and EN 12094-2003.
