• Use heptafluoropropane fire extinguishing agent. Heptafluoropropane (HFC-227ea) fire extinguishing agent is colorless, odorless, non-conductive, low-toxic, and has no secondary pollution. Its ozone depletion potential ODP=0, greenhouse effect potential GWP=0.6, atmospheric retention life ALT=31 years, and non-toxic screening concentration NOAEL=9%. The basic concentration of fire extinguishing design C=8%, with good cleanliness (completely vaporized in the atmosphere without leaving residue), is the best substitute for halogenated hydrocarbon fire extinguishing agent.

• After receiving the signal from the flame detector, heptafluoropropane is filled into the spray room for instant fire extinguishing to prevent explosion, providing users with the greatest safety guarantee.

• The self-diagnosis device can alarm for equipment failure to ensure the reliability of operation;

• The alarm conditions and alarm control mode can be set according to the temperature characteristics of the installation environment.

• When all devices are in automatic state, when there is a certain concentration of smoke (or temperature rises) in a certain protection zone, the smoke (or temperature) fire detector in the protection zone will be activated and send a single fire alarm signal to the fire alarm controller, and the controller will enter the single fire alarm state, and drive the electric alarm to output a single fire alarm signal at the same time. At this time, the control signal to start the fire extinguishing system will not be output. As the fire in the protection zone spreads, the temperature continues to rise (or the smoke increases), and the temperature (or smoke) fire detector in another circuit will be activated and send another fire alarm signal to the fire extinguisher controller. At this time, the controller immediately enters the automatic fire extinguishing program, starts to delay according to the set time, and outputs a composite fire alarm signal and linkage signal at the same time, and starts the sound and light alarm of the protection zone (turns off the air conditioner, power supply and exhaust device, fire damper, fire shutter, etc.).
