Shaanxi automatic fire alarm system is composed of triggering the fire alarm, fire alarm system and a device having other auxiliary functions consisting of fire alarm systems. It can fire smoke detectors in the early brands, will burn smoke, heat and light radiation and other physical quantities produced by temperature, smoke and fire detectors become sensitive and other electrical signals, transmitted to the fire alarm control fire smoke detection device, and also shows the site of the fire, the time the fire broke records.

Xi'an has a high density of carbon dioxide fire extinguisher, about 1.5 times that of air. At atmospheric pressure, the carbon dioxide will be immediately vaporized liquid, generally produce 1kg of liquid carbon dioxide of about 0.5 cubic meters of gas. Thus, when the fire, carbon dioxide gas can be excluded in the combustion air surrounds the object surface or distributed relatively confined space, or reducing fuel around the oxygen concentration inside the protected space type smoke detectors, fire produces choking action. In addition, carbon dioxide is discharged from the storage container, will be made of liquid rapidly vaporized gas, and attract some of the heat from the surroundings, play a role in cooling. Smoke detectors companies, Xi'an fire manufacturers (certification), Xi'an, Shaanxi smoke detectors provided by the Fire Equipment Co. Jiwei. Shaanxi Jiwei Fire Equipment Co.
