What is the principle of fire fighting?
The automatic fire alarm device is started by starting the alarm valve button instead of relying on smoke sensing and temperature sensing probes to detect the change of temperatureIs the signal to the control center issued by the alarm button, the control center sends out the instruction to start the fire pump, start at the same time delayer, sends a signal to the fire department; control center issued a warning signal, fire shutter doors start the fire to control the fire; fire alarm automatic open auxiliary control spraying device for partition, evacuation time connection; fire pump to control the fire, waiting for fire rescue personnel.
The principle is that there is a separate line and module control between these systems and the fire control center. When manual intervention is needed, the operation of these devices can be implemented directly by the "strong" button.
In fact, through the fire alarm control center, some linkage systems were artificially forced to start.
