Automatic Aerosol fire extinguishing device fire exintuisher generator
Type D working principle: Fire alarm controller or gas fire control is used to detect the fire signal. When a fire is detected, a start 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 and quickly generated. The aerosol sprayed out and fired quickly.
W-type working principle: When the ambient temperature reaches the starting temperature of the heat-sensitive wire or comes into contact with an open flame, the heat-sensitive wire ignites spontaneously and passes it to the fire extinguishing device. After the fire extinguishing device receives the start signal, the internal fire extinguishing agent will be activated and gas will be generated quickly The sol sprayed out and fired quickly.
C is the start of magnetic power generation: When the ambient temperature exceeds the set temperature limit, the thermal element acts and the magnetic moving rod is released. Under the action of the spring, the magnet fixed on the rod passes through the induction coil and cuts the magnetic lines of force. Causes the coil to generate electrical pulses, which are transmitted to the fire extinguishing device along the connection line from the contact to the terminal, and the fire extinguishing device is started.
