Product description

Product Introduction

◆ Cabinet-type heptafluoropropane (HFC-227ea) fire extinguishing system, also known as a prefabricated fire extinguishing system, refers to a fire extinguishing system that pre-assembles the extinguishing agent storage device, pipelines, nozzles, pressure signalers, drive components, etc. into a complete set. When a fire occurs in the protected area, the heat and smoke detectors send fire signals. After logic analysis by the automatic fire alarm and extinguishing controller, a combined audible and visual alarm signal is issued, and a linkage command is simultaneously issued to shut down the linkage equipment. After a certain delay, a fire extinguishing command is issued, activating the electromagnetic valve actuator, opening the container valve, releasing the extinguishing agent, and implementing fire extinguishing. If on-duty personnel discover a fire, they can press the emergency start button outside the protected area door to carry out fire extinguishing operations. The electromagnetic valve actuator is also equipped with a manual button, which allows for mechanical emergency manual operation for fire extinguishing in emergencies.

Application places

◆ It is widely used for fire protection in smaller spaces such as computer rooms, telecommunications centers, power distribution rooms, transformer rooms, archives, data rooms, valuables warehouses, and oil storage rooms.
