Principle:
Type E working principle: Fire signal is detected by fire alarm controller or gas fire extinguishing control. When fire is detected, the starting signal is output to the fire extinguishing device. After the fire extinguishing device receives the start signal, the internal fire extinguishing agent will be activated. The nano-type aerosol fire extinguishing agent is sprayed out for rapid fire extinguishing.
TH type working principle: When the ambient temperature reaches the starting temperature of the thermal line or when it contacts the open flame, the thermal line is self-igniting and transmitted to the fire extinguishing device. After the fire extinguishing device receives the start signal, the internal fire extinguishing agent is activated, and the nano-type aerosol fire extinguishing agent is quickly generated and sprayed for rapid fire extinguishing.
ST type working principle: When the ambient temperature reaches the starting temperature, the temperature sensing ball releases the potential energy of the striking rod. When the striking rod hits the generator, the generator is activated by an internal fire extinguishing agent, which rapidly produces a nano-type aerosol fire extinguishing agent and ejects it for rapid fire extinguishing.
