Fire extinguishing mechanism

Heptafluoropropane fire extinguishing agent is a colorless, odorless, non conducting gas with no solid or liquid residue after extinguishing. Chemical formulaCF3CHFCF3The molecular weight is170The density is approximately equal to that of air6Twice. Its fire extinguishing mechanism is a consistent chemical chain reaction, which also has the functions of cooling and reducing oxygen concentration. Its fire extinguishing mechanism and efficiency are similar to halogenated hydrocarbons“1301”Similarly, forAClassBAll types of fires can effectively extinguish them.

Characteristics of gas fire extinguishing

1.The protected area has independent functions of automatic fire detection, automatic alarm, fire extinguishing control, and gas fire extinguishing.

2.It has two types of electric start modes: automatic and manual, as well as manual emergency forced start mode.
3.In automatic mode, the system has the function of automatically releasing heptafluoropropane gas to extinguish fires when two different types of fire detectors act in combination. Before starting to release gas, have30The second delay function can also emit sound and light alarms inside and outside the protected area to notify personnel to evacuate.

4.In the manual electric start mode, personnel can use the start button outside the protected area to start the heptafluoropropane fire extinguishing equipment, which also has a delayed sound and light alarm function before gas release (this manual start mode is effective in automatic mode).
5.When the fire extinguishing device cannot be electrically started due to electrical or control device failures in the system, heptafluoropropane gas can be manually or mechanically released between the bottle groups to extinguish the fire.

6.When the gas fire extinguishing device is automatically activated, during the delay phase before release, the manual emergency stop button can be used outside the area to terminate further actions of the system.

7.Whether in manual or automatic mode, the action of any detector will trigger an effective alarm.
8.When a fire alarm is triggered and the fire extinguishing equipment is activated in this system, the fire alarm and linkage fire extinguishing controller should provide feedback signals to the centralized alarm controller in the fire control center.
