A, trigger device:
Fire detector and manual alarm button.
Second, the fire alarm device:
The fire display panel (also called repeater panel or floor display) is used to receive the signal sent by the fire alarm controller and display the location or area where the fire alarm is sent. It is usually set in a field area where people often exist or move, and no fire alarm controller is set.
Third, the fire alarm device:
Fire alarm device is an automatic fire alarm system, which is used to send out fire alarm signals different from ambient sound and light. It is called a fire alarm device. Audible and visual alarm is one of the most basic fire alarm devices. It sends a fire alarm signal to the alarm area through sound and light to remind people to take actions such as safe evacuation, fire fighting and disaster relief.
Fourth, the power supply:
The automatic fire alarm system belongs to fire-fighting electrical equipment and should be equipped with main power supply and DC standby power supply. The main power supply should be fire power supply, and the standby power supply should generally be battery pack. V. Contact with other auxiliary control functions:
In the automatic fire alarm system, after receiving the fire signal from the trigger device, the equipment that can automatically or manually start the relevant fire equipment and display its working status is called the fire linkage control device, and the fire alarm controller is connected with the linkage device through the output module.
Extended data:
Automatic fire alarm system is generally designed in three forms: regional automatic fire alarm system, centralized automatic fire alarm system and control center alarm system. According to the basic characteristics of intelligent building, the alarm system of control center is a suitable way.
The design points of the automatic fire alarm system for intelligent buildings are as follows: (1) determine the fire type according to the characteristics of the protected object when it burns; According to the required protection area; Determine the total capacity of the fire alarm controller according to the total number of fire detectors and the number of other alarm devices (such as manual alarm); According to the divided alarm areas; Determine the linkage control mode according to the fire fighting equipment;
According to the requirements of fire prevention and extinguishing, determine the logical relationship between alarm and linkage; Finally, the adaptability of automatic fire alarm system and intelligent building "3AS" (building equipment automation system, communication automation system and office automation system) should be considered.
