Automatic fire alarm system components

Five components of automatic fire alarm system:

I. Trigger device:

Fire detector and manual alarm button.

Second, the fire alarm device:

Fire display panel (also known as the display panel or floor display) is used to receive signals from the fire alarm controller, showing the fire alarm parts or areas, usually set in the frequent presence of people or activities and not set the fire alarm controller on-site area.

Three, the fire alarm device:

Fire alarm device is in the automatic fire alarm system, used to send out the difference between the environment sound, light fire alarm signal device is called a fire alarm device. Sound and light alarm is one of the most basic fire alarm device, it is sound, light to the alarm area to send a fire alarm signal to remind people to carry out safe evacuation, fire fighting and other actions.

Four, power supply:

automatic fire alarm system belongs to the fire electrical equipment, there should be a main power supply and DC backup power. Its main power supply should be used for fire power, backup power generally use battery packs.

V. Other auxiliary control functions of the linkage device:

In the automatic fire alarm system, when the fire signal is received from the trigger device, can automatically or manually start the relevant fire equipment and display its working state of the equipment, known as the fire linkage control device, the fire alarm controller and the linkage device through the output type of module to connect.

Expanded information:

Automatic fire alarm system is generally divided into three forms of design: regional automatic fire alarm system, centralized automatic fire alarm system and control center alarm system. and control center alarm system. On the basic characteristics of intelligent buildings, the control center alarm system is the applicable way.

Intelligent buildings in the automatic fire alarm system design points are: according to the characteristics of the protected object when the fire burns to determine the type of fire; according to the required protection area parts; according to the total number of fire detectors and other alarm devices (such as hand alarm) number of fire alarm controllers to determine the total capacity; according to the division of the alarm area to set up a regional alarm controllers; according to the fire equipment to determine the linkage Control mode;

According to the fire fighting requirements to determine the logical relationship between the alarm and the linkage; and finally consider the automatic fire alarm system and intelligent building "3AS" (construction equipment automation system, communication automation system, office automation system) adaptability.
