The Code for the Design of Fire Alarm Systems is as follows:
Article After the fire alarm, the fire control equipment shall have the following functions for the linkage control object:
1. Stop the fan in the relevant part, close the fire damper, and receive its feedback signal;
2. Start the smoke prevention and smoke exhaust fans (including positive pressure fans) and smoke exhaust valves of the relevant parts, and receive their feedback signals.
Article After the fire is confirmed, the fire control equipment shall have the following functions for the linkage control object:
1. Close the fire doors and fire shutters of the relevant parts and receive their feedback signals;
2. Send a control signal to force all elevators to stop on the first floor and receive its feedback signal;
3. Turn on the fire accident lighting and evacuation indicator lights;
4. Cut off the non-fire power supply of the relevant parts.
Article After the fire is confirmed, the fire control equipment shall be connected to the fire alarm device and the fire accident broadcast in the evacuation order. The control procedures of the alarm device shall meet the following requirements:
In the event of a fire on the first and second floors and above the second floor, it is advisable to connect the fire floor and the adjacent upper and lower floors first;
2. In the event of a fire on the first floor, it is advisable to connect the first floor, the second floor and the underground floors;
3. In the event of a fire in the basement, it is advisable to connect the underground floors and the first floor first.

Look at the design description, general fire partitioning.
It is a point that is linked, and gas fire extinguishing is a two-point alarm jet.

Answer: 1).Induced linkage: It is generally a simulated fire alarm signal, and the specific method is to trigger the smoke sensor, temperature sensor, and manual alarm button alarm, and the alarm host should be played into an automatic gear before that.
2).After the main engine confirms the fire, it sends out a linkage signal, and the main execution equipment is as follows:
1.The fire broadcast host is connected to the fire state, and the fire broadcast on the alarm floor and the upper and lower two floors shall be started. If it is an audible and optic alarm, the acousto-visual alarm is activated, and the linkage relationship is the same as that of fire broadcasting;
2.Fire shutters (if installed) should be activated;
3.Normally open fire doors should be closed;
4.The power supply of the air conditioner (if there is a duct air conditioner installed, such as ** air conditioner) should be cut off, and the electric fire damper on the air conditioning pipeline should be closed;
5.The smoke fan (if it is located in the stairwell or front room, it is a positive pressure blower, if it is a basement, it is a make-up fan), and the smoke exhaust fan should be started;
6.Relative to 5, the relevant air supply outlet (stairwell and front room are positive pressure air outlets), smoke exhaust outlets should be started, the specific linkage relationship is as follows, if in the basement or large space shopping mall, then start the smoke exhaust outlet and the air supply outlet of this fire partition. If it is on a floor, the air supply outlets in the stairwell should be fully opened, the front room supply and distribution ports should be opened on this floor and the upper and lower floors, and the smoke exhaust vents should be opened on this floor and the upper floor.
7.It is related to , that is, any smoke exhaust outlet should start the relevant smoke exhaust machine, and any air supply outlet should start the relevant blower.
8.The elevator should be forced down to the ground floor (all elevators), and the fire elevator should be able to work after special operations and reach the top floor within 60s.
9.Strong cutting means that the non-fire power supply of this fire partition or this floor should be cut off.

Make the fire linkage controller in automatic and manual working state respectively, check its status display, and according to the current national standard "fire linkage control system" GB16806
The relevant provisions of the following functions shall be checked and recorded, and the controller shall meet the corresponding requirements:
1 Self-test function and operation level.
2. When the connection between the fire linkage controller and each module is broken and short-circuited, the fire linkage controller can send out a fault signal within 100 seconds.
3. When the connection between the fire linkage controller and the standby power supply is broken and short-circuited, the fire linkage controller should be able to send a fault signal within 100s.
-
The fire linkage controller should send out sound and light alarm fault signals in 100s.

Summary. How many minutes does the fire linkage control cabinet report the fire alarm and the automatic state is normalHello, there are the following 4 situations (1) When there is a fire detector fire alarm signal input, the controller should send out fire alarm sound and light signal within 10s. When there is a manual fire alarm button alarm signal input, the controller should send out a fire alarm sound and light signal within 10s, and clearly indicate that the alarm is a manual fire alarm button alarm.
2) When there is a fault inside the controller and between the controller and its connected parts, the controller should send out a fault sound and light signal that is clearly different from the fire alarm signal within 100s, and the fault sound signal should be able to be manually eliminated, and then when the fault signal is input, it should be able to start again; The fault light signal should be maintained until troubleshooting. (3) The controller should start the relevant control output within 3s after sending out the fire alarm signal (except when there is a delay requirement). (4) The controller shall send out the corresponding sound and light signal within 10s after receiving the feedback signal of the fire linkage control equipment, and keep it until the fire linkage equipment recovers.

Hello dear! The main function of the fire alarm and linkage system is to automatically or manually send out fire alarm signals, start fire linkage equipment, and alarm the fire source in case of fire and other emergencies, so as to minimize the losses caused by fire. Its main functions include the following aspects:
1.Fire alarm function closure energy: detect fire signals through sensors, manual buttons, etc., and send fire alarm signals to the fire control car clamping center.
2.Linkage control function: start the fire pump, sprinkler system, gas fire extinguishing system and other linkage equipment to control the spread of fire and minimize fire damage.
3.Early warning function: monitor abnormal conditions such as temperature and smoke, and warn of fire risk in advance.
4.Self-test function: self-test the equipment to ensure the normal operation of the equipment.
In short, the main function of the fire alarm and linkage system is to ensure the safety of personnel and property, control the fire as soon as possible, quickly and effectively, and reduce the loss caused by the fire. Hope it helps!
Including, the automatic fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices, it has the ability to produce smoke, heat, flame and other physical quantities produced by combustion in the early stage of the fire, through the fire detector into an electrical signal, transmitted to the fire alarm controller, and at the same time in the form of sound or light to notify the fire layer and the upper and lower adjacent layers to evacuate, the controller records the location of the fire, the time, etc., so that people can find the fire in time, and take effective measures in time, Extinguishing the initial fire and minimizing the loss of life and property caused by the fire is a powerful tool for people to fight against fire. >>>More
