7.3.2 Heptafluoropropane Automatic Fire Extinguisher

When the FusionDC1000 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 fire alarm control panel, which generates an electromagnetic valve
start voltage to start the electromagnetic valve of the fire cylinder. Then the fire
cylinder valve is opened, and extinguishant is released into the protected zone.

Provides a signal input port for gas release confirmation (onsite pressure
feedback). The gas release confirmation mode can be set by users. There are
two modes available: onsite pressure feedback and electromagnetic valve
drive.
Allows the system to identify states such as fault, fire alarm, and gas release,
and provides the gas release indicator drive, fire alarm horn/strobe drive, and
alarm bell drive.
Provides the single-point test function for detectors, making the working
status and test data of detectors intuitive.
Allows you to set the working status of the area control unit to manual or
automatic.
Provides a 4.3-inch color LCD, and working status printer.
