3.5.3 (Optional) Heptafluoropropane Fire Extinguisher

When the FusionModule1000 catches fire, a lot of smoke is generated and the temperature
rises sharply. The smoke detector and heat detector send fire alarm signals to the
extinguishant control panel, which generates an electrical actuator start voltage to start the
electrical actuator of the fire cylinder. Then the fire cylinder valve is opened, and
extinguishant is released into the protected zone.
Heptafluoropropane (HFC-227ea) is a colorless, odorless, non-conductive, and secondary
pollution-free gas extinguishant. It features cleanness, low toxicity, good electrical insulation,
high fire extinguishing efficiency, zero threat to the ozonosphere (ODP = 0), and short
residual time (ATL = 34Y).
