How to cut off the non-fire power supply in the fire control room after the fire?

The fire control room (automatic fire alarm system) is a fire alarm system composed of trigger device, fire alarm device, fire alarm device and devices with other auxiliary functions. It can transmit physical quantities such as smoke, heat and light radiation produced by combustion through temperature induction in the early stage of fire. Fire detectors, such as smoke detectors and light detectors, turn into electrical signals, which are transmitted to the fire alarm controller. At the same time, the location of the fire is displayed and the time of the fire is recorded. General automatic fire alarm system and automatic sprinkler system, indoor fire hydrant system, smoke control system, ventilation system, air conditioning system, fire door, fire shutter, smoke screen wall hanging, non-fire power supply and other related equipment linkage, automatically or manually issued instructions to start the corresponding devices.

The wiring diagram of automatic fire alarm system is as follows:

As can be seen from the schematic diagram, when a fire occurs, the system sends a signal to the fire control module, and the module instructs to cut off the non-fire power supply controller, and feeds back the cut-off signal to the module to the fire control center.

The fire control module, also known as the input and output module, is an important part of the fire linkage control system, which is used to connect external devices such as smoke exhaust valves, air supply valves and fire dampers in the automatic fire alarm system. The module has a pair of normally open and normally closed contacts, and the contacts on the module are connected with external circuits to realize the linkage control of external devices.

The above requirements are specified in Code for Design of Automatic Fire Alarm System (GB 50116-2013):

And designed it.
