First of all, its classification is roughly as follows:
1. According to the types of information collected on site, it can be divided into smoke detector, temperature detector, flame detector and special gas detector.
2. According to the principle of equipment collecting field information, it can be divided into ion detector, photoelectric detector and linear detector.
3. According to the installation mode of the equipment in the field, it can be divided into point detectors, cable detectors and infrared beam detectors.
4. According to the connection mode between the detector and the controller, it is divided into bus system and multi-line system; Among them, the bus system is divided into coding and non-coding; Codes are divided into electronic codes and dip switch codes, and dip switch codes, also called dialing codes, are divided into binary codes and ternary codes.
In addition, there is more than one manufacturer at home and abroad, and the equipment produced by each manufacturer is different. You can search separately, such as: Gulf Fire Equipment Company, Annie Ann Fire Equipment Company, No.404 Factory of China Nuclear Industry Department, Shenyang Fire Research Institute, Shenzhen Yongxing Fire Equipment Company and Beijing Liuhe Fire Equipment Company.
Second, its characteristics:
1, advantages:
No matter what kind of detector is produced, the fire can be detected with high sensitivity. Installation is relatively simple.
2. Disadvantages:
The equipment produced by each company is not universal, independent and enthusiastic, not only can't replace each other. They can't communicate with each other.
