After the fire alarm, the fire control room duty personnel should stop the fan in the relevant part,

Right. After the fire alarm, the on-duty personnel of the fire control room should implement control operations for the following linkage objects:

1.Immediately notify the relevant personnel to the alarm scene to confirm whether there is a fire;

2.Stop the fan in the relevant area, close the fire damper, and pay attention to receiving its feedback signal.

3.Start the smoke prevention and smoke exhaust fan and smoke exhaust valve in the relevant parts, and pay attention to receiving their feedback signals.

In case of fire, the smoke exhaust fan is not turned off immediately, otherwise how to exhaust the smoke. Generally, the fire damper and the fan are linked. In the case of more than 280 degrees, the fire damper can run for about half an hour, beyond this time, the fire damper is closed, the fan stops, and this time is the escape time prepared for personnel.

After this time, the smoke exhaust of the fan can no longer control the site, and it is difficult for the fire damper to maintain good temperature in high temperatures. The blower is also linked to the fire alarm, and should be opened and closed at the same time. The air supply and smoke exhaust should occur at the same time in the basement, in order to ensure the oxygen required for personnel to escape, to provide air supply not less than the smoke exhaust volume.

Of course, in the case of production fans (e.g. feeder fans), they need to be stopped.

The blower and exhaust fan should be stopped accordingly The fire smoke exhaust fan should be in working condition Mainly used to exhaust smoke and reduce the danger Generally, the fire fan only works when there is a fire.

Check the alarm point immediately, and if there is a false alarm, the alarm will be silenced and reset. In case of fire, it shall be implemented according to the fire protection deployment.

This depends on the location of the fire door, if the fire door is between the two areas, for isolation, and both areas have separate safety evacuation channels, it should be closed, so that the fire area can be isolated to prevent the spread. If the fire door is in a safe evacuation route (escape hatch), it should not be closed, which is wrong.

It stands to reason that the fire doors in the evacuation area are normally closed (cannot be locked), unless it is a normally open fire door with signal feedback and can be automatically closed. The cost of normally open fire doors is high, and owners or developers are generally reluctant to use them, or use them as little as possible. In reality, many properties and owners often open or lock the fire door for the convenience of management and use, which requires manual operation during the fire, and it is still dangerous if it is too late.

Close the fire door and run to the **. If it is determined that it is a fire, the host will be automatic, and all the doors that install access control will not work, how do you say he closes, is it not suffocating people to death、、、 is the fire door you said is a roller shutter door.

After confirming the fire, close the fire door at the relevant part

Haha, dude, I'm looking for it too, for the same reason as you

First of all, it is silenced. Notify the security personnel or the other person on duty to go to the scene to find out. False positive words.

Find out the cause, record it, and reset the linkage. Real fire alarm, debugging linkage to automatic state. Activate the relevant fire-fighting facilities according to the situation, such as broadcasting, smoke extractors, water pumps, etc.

Dial 119. Notify the leaders and the internal volunteer fire brigade of the unit to start the fire plan.

1. The automatic fire alarm system device includes various fire detectors, manual alarm buttons, regional alarm controllers and centralized alarm controllers, etc.;

In the early stage of the fire, the smoke, heat, flame and other physical quantities generated by combustion are turned into electrical signals through the fire detector, transmitted to the fire alarm controller, and at the same time notify the entire floor to evacuate in the form of sound or light, and the controller records the location and time of the fire, so that people can find the fire in time and take effective measures in time to extinguish the initial fire.

2. The fire linkage system includes the fire linkage controller, the fire control room display device, the transmission equipment, the fire electrical control device, and the emergency power supply of the fire fighting equipment; Fire electric devices, fire linkage modules, fire hydrant buttons, fire emergency broadcast equipment, fire protection ** and other equipment and components.

The automatic fire alarm and fire linkage control system consists of a trigger device, an alarm device, an alarm device, a linkage device and a power supply.

The trigger device is an alarm trigger device, there are two kinds of manual and automatic trigger devices, the manual trigger device is the manual fire alarm button, and the automatic trigger device is the fire detector.

The alarm device is a device that receives or displays a fire alarm, and the fire alarm controller and fire display panel are all alarm devices.

The alarm device mainly alarms to alert the attention of on-site personnel, and the alarm device has sound, light or sound and light sirens.

The linkage device is the automatic fire alarm and fire linkage controller after receiving the external fire alarm signal, it should be started in conjunction with some external equipment, such as linkage smoke prevention and exhaust system, emergency lighting, fire shutter and other systems to start, cut off non-fire power supply, etc.

The power supply is also an indispensable part of the system, and the automatic fire alarm and fire linkage control system generally uses UPS power supply to supply its power.

1. The automatic fire alarm system is generally composed of two parts: fire detector and fire alarm.

Fire detectors are installed on the site to monitor whether there is a fire alarm at the scene;

Fire alarms are installed in the fire control center and manage all fire detectors.

2. The fire linkage system is used to control the linkage equipment, and there are multi-wire linkage control systems and bus linkage control systems.

1.In the multi-wire linkage control system, 2-6 lines must be connected from the linkage controller to each linkage equipment, which is generally suitable for buildings with few linkage equipment. For buildings with more linkage equipment, if the multi-line linkage control system is used, the engineering construction is more difficult, and it is best to use the bus linkage control system.

2.In the bus system linkage control system, the automatic fire linkage system is composed of a linkage system and a control module. Between linkage controller and control module is two buses or four buses, each group of buses can be connected with a plurality of control modules, when need to start linkage equipment, linkage controller sends out a start command, control module action, control module starts linkage equipment again.

Emergency procedures in the control room.

After receiving the fire alarm, the personnel on duty should immediately confirm the fire in the fastest way, and immediately transfer the fire alarm system linkage control switch to the automatic state, and dial 119 to call the police at the same time.

Immediately activate the emergency evacuation and fire extinguishing plan within the unit, and report to the person in charge of the unit at the same time.

There are five major operating systems in the fire control room, namely: fire alarm system, alarm linkage system, fire alarm graphic display system, closed-circuit television system, and broadcast communication intercom system.

The fire control room is the heart of the building. The fire control room (fire control room) fire control officer holds the fire control book (fire control certificate).

Occupation definition. Personnel engaged in fire safety management, fire safety inspection and operation and maintenance of building fire protection facilities are also the control center of building fire protection facilities.

Facilities include: Remote Fire Alarm Communication System, Automatic Fire Alarm System, Fire Broadcast Communication System, Fire Pump House, Smoke Extraction and Ventilation System.

Evacuation lighting system Automatic fire extinguishing system.

Basic configuration: automatic fire alarm system, fire linkage system, broadcasting system, communication system. Other configurations are that each building is designed according to its use function additionally, such as monitoring (CCTV) and other weak current systems are generally integrated in the fire center (for the convenience of management), but it has nothing to do with fire fighting.

Fire elevator forced landing, non-fire electric energy cut-off is a function contained in the linkage system, can not be called a system independently. Others, such as fire sprinkler systems, fire hydrant systems, and smoke prevention and exhaust systems, are controlled by the fire center and are only regarded as external systems. The fire alarm graphic display system is only a function of the fire host, and it is not required at all if it is the minimum configuration.

Fire alarm system: on the fire alarm host.

Alarm linkage system: on the alarm linkage host (some fire protection systems are two machines) fire alarm graphic display system: a host computer, with graphics to show the location of the specific alarm CCTV system: CCTV system operating table.

Broadcast communication intercom system, that is, some broadcasting, telephone stations, etc., is relatively simple.

That's all there is to it.

1.Fire broadcast system.

2.Fire alarm system.

3.Fire Communications**.

4.Fire sprinkler system.

5.Fire hydrant system.

6.Smoke prevention and exhaust system.

7.The fire elevator made a forced landing.

8.Non-fire-fighting electrogen cut-off.
