Electrical starting theory:

While fire happening the fire alarm controller / Aerosol fire extinguishing controller will detect it and output a start signal to our small whirlwinds s type fire extinguisher. Once received the start signal, the inside elixir will be activated then extinguishing aerosol will be produced and spurt out promptly for a rapid fire extinguishing

Thermal Line Operating:

While the environment temperature reaches the start temperature of thermal line or it contacts with open flame, the thermal will have self-ignition, and pass to the small whirlwinds extinguisher device, Once received the start signal, the inside elixir of extinguisher will be activated then extinguishing aerosol will be produced and spurt out promptly for a rapid fire extinguishing.
