mechanical emergency operating mechanism can also be added. This

extinguishing device
Under normal conditions, the control mode of the fire alarm
controller is selected in the "automatic" position, and the fire
extinguishing device is in the automatic control state. When a fire
occurs in the protected area, the fire detector sends a fire alarm
signal, and the fire alarm controller sends an audible and visual
alarm signal, and at the same time sends a linkage command to shut
down ventilation equipment such as air conditioners, fans, and
fireproof roller shutters. After a delay of 0~30 seconds (people in
the protected area must evacuate quickly at this time), the
DC24V/1.5A fire extinguishing signal is output to drive the starter
electromagnetic to open the container valve on the fire
extinguishing agent storage bottle, and release HFC-227ea to
extinguish the fire.
2) Manual control
When someone is working or on duty in the protected area, the
control mode of the fire alarm controller is selected in the
"manual" position, and the fire extinguishing device is in the
manual control state. If a fire occurs in a protected area, press
the "start" button on the fire alarm controller to start the fire
extinguishing device according to the "automatic" program to
extinguish the fire. You can also press the "emergency start"
button set at the door of the area after confirming that all
personnel have evacuated, and the delay will be 0-30 seconds to
release HFC-227ea to extinguish the fire. When a fire alarm occurs,
if it is found that there is no need to activate the fire
extinguishing device to extinguish the fire within the delay time,
the "Emergency Stop" button on the fire alarm controller or outside
the protection area door can be pressed to terminate the fire
extinguishing procedure.
