Photographic and other smoke and fire detectors into electrical signals, transmitted to the fire alarm controller, and also shows the site of the fire, the fire record of the time. General fire alarm system and automatic sprinkler system, fire hydrant systems, smoke control systems, ventilation systems, air conditioning system, fire doors, fire shutter, smoke screen and other related equipment interaction, automatically or manually issue commands to start the corresponding device.
(A) of the trigger devices in automatic fire alarm system, automatic or manual fire alarm signal devices generate called trigger conditions, including fire detectors and manual fire alarm button. Fire detector is able to fire parameters (smoke, temperature, flame radiation, gas concentration, etc.) response, and automatically generate a fire alarm signal devices. Fire response parameters according to different fire detectors into heat detectors, smoke detector, sensitive fire detectors, combustible gas detectors and fire detectors five basic types of composite. Different types of fire detectors for different types of fires and different places. Manual fire alarm button fire alarm signal generated manually start the automatic fire alarm system devices, automatic fire alarm system is an indispensable component of the.
(B) the fire alarm device in automatic fire alarm system to receive, display and transmit fire alarm signals, and can send control signals and control functions with other auxiliary equipment as the fire alarm device instructions. Fire alarm control is one of the most basic kind. Charged with the fire alarm control fire detectors provide a stable working power; detector and the working status of the system itself; the reception, conversion, processing a warning of fire detectors Shuchu; Jinxing sound and light alarm; Zhishi specific location and alarm time; the same time supporting the implementation of appropriate control and many other tasks. Fire alarm system is a core component. In the fire alarm devices, some devices such as break, regional monitors, fire shows and other functions can not complete disc alarm device, which can be regarded as the evolution of fire alarm controller or supplement. Under certain conditions applied, and the fire alarm device fire alarm control belong.
The basic function of fire alarm control are: the main power, backup power automatically converted, standby power charge function, power failure monitoring function, power functions working status indicator, power supply for the detector circuit function, control sensors or system failures, sound and
light alarm, fire sound, light alarm, fire alarm and memory function, clock function unit, with priority being given fault function fire alarm, sound alarm sound audible alarm mute and again.
(C) fire alarms in automatic fire alarm system to send different from the environment, sound, light the fire alarm signal device called the fire alarms. It sound, light and sound approach to the issue of fire alarm signals alarm area to warn people to adopt safe evacuation, fire fighting and rescue measures.
D) Fire control equipment in automatic fire alarm system, when receiving the fire alarm, automatically or manually start the related fire-fighting equipment and display devices of their state, known as the fire control equipment. Include fire alarm control, automatic fire extinguishing system control device, fire hydrant system control devices, smoke exhaust system and air conditioning and ventilation system control device, normally open fire doors, fire shutter control device, the lift back down control equipment, and fire emergency radio, fire alarms, fire communications equipment, fire evacuation signs and emergency lighting control devices, control devices in some or all. Fire control equipment normally installed in the fire control center to facilitate the implementation of centralized control.
While others set fire control equipment, fire fighting equipment is located in the charged field, but its actions must be returned fire control signal, combined with the implementation of centralization and decentralization of control.
(E) fire alarm system power supply electrical equipment belonging to the fire, the main power should be in the fire power, standby power use of battery. In addition to fire alarm system power controller, power supply, but also related to the system for the fire control equipment such as power supply.
火灾自动报警系统
传统电子安全报警系统主要是通过传感器自动检测，产生报警信号，从现场发出报警信号或通过专门电缆近距离报警，从而引起人们的警觉。通过多年的研究和发展，现在的报警器可以说是门类众多。由于报警器的飞速发展和社会各个领域的急切需要，能应用的领域越来越多，特别是在民用领域更是急速发展。 近年来，红外线报警器已经成为报警领域的一个热点，由于其采用的是不可见的红外线探测，所以具有隐蔽性好、安全等特点。红外线传感器按机理不同可以分为光探测型和热探测型。光探测传感器是利用光子效应的红外探测器。这类传感
