Some standard content:
— 1996 | It has strong anti-interference ability, thereby reducing the false alarm rate of the detector. This standard is part of the GB10408 "Intrusion Detector" series of standards. The format of this standard refers to GB10408.6-91 "Microwave and Passive Infrared Composite Intrusion Detector", and the technical requirements and test methods adopt GB10408.1-89 "General Technical Conditions for Intrusion Detectors" GB10. 408.2-89 "Ultrasonic Intrusion Detector" and GB10408.5---89 "Passive Infrared Intrusion Detector" relevant chapters and articles.
There is currently no international standard for this type of product. This standard adopts IEC839-2:1990 "Requirements for Intrusion Alarm Systems" in terms of sensitivity and detection range, resistance to hot air flow interference and resistance to small animal interference, and test methods. In terms of methods, the relevant provisions of UI.639 (1984 version) "Intrusion Detector" are equivalently adopted. This standard is proposed by the Ministry of Public Security of the People's Republic of China. This standard is under the jurisdiction of the National Security Alarm System Standardization Technical Committee. This standard is drafted by Shanghai China Resources-Defu Optoelectronics Co., Ltd. The main drafter of this standard is Huang Keyi.
