Operation principle of fire alarm system input / output module
Automatic fire alarm system is composed of trigger device, fire alarm device, fire alarm device and other auxiliary functionsFire alarm system buttonFire alarm system. It can early in the fire, smoke, heat and light radiation and other physical quantities of burning, the temperature and smoke and sensitive 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.

It can also be combined with various fire extinguishing facilities and communication devices according to the requirements of the project to form a central control system. That is, a complete fire control system is composed of automatic alarm, automatic fire extinguishing, safety evacuation guidance, system process display and fire control file management. A fire detector is a device for detecting fire, because at the stage of fire, smoke, fire and fire will be accompanied by fire. These smoke, heat and light can be switched from detectors to electrical signals to alarm or to start automatic fire extinguishing systems and extinguish fires in time. The alarm signal will be converted to areas where the floor of the detector sends out sound and light alarm, and display the fire room number on the screen; centralized alarm also can monitor several floors (if the monitor is located in the building fire control center) automatic fire extinguishing system output signal or control. Alarm signal is received by way of sound and light show, the screen also shows the specific fire floor and room number on the machine stop time go first alarm clock to record the use of the machine specific phone, but also quickly issued instructions and alarm to the fire brigade. In addition, the fire extinguishing system can be controlled or transmitted to the fire control room.
Automatic fire alarm system (Fire Alarm System, referred to as FAS system) for early detection of people informed of the fire, and promptly take effective measures to control and extinguish the fire, an automatic fire facilities and set in a building or in other places, people are the same as a powerful tool to fight the fire.
