Details of the category and function of the anti-theft alarm controller

Anti-theft alarm controller category and function introduced

Anti-theft alarm controller is the key equipment of the anti-theft alarm system, it is China's mandatory certification of the product (that is, a 3C certification), the national standard GB12663-2001 has a lot of specific and detailed requirements for the function of this type of product. The national standard GB12663-2001 also has clear requirements for the environmental adaptability of this type of product, which includes climate and mechanical environmental adaptability and electromagnetic compatibility adaptability. At the same time, the national standard GB12663-2001 also has clear requirements for the safety of such products. According to the GB12663-2001 national standard definition of "general technical conditions for anti-theft alarm controller", Burgar-atarm controunito should be set in the intrusion alarm system to set guard, disarm, judge, test, indicate, transmit alarm Information and equipment that performs some control functions. Anti-theft alarm controller according to the protection function is divided into A, B, C three levels: A level for the lower protection function level; B level for the general protection function level; C level for the higher protection function level.

The central alarming machine has features such as alarm notification, time display, information storage, alarm, and output, and an alarm with address code is output to the PC. The database in the PC will provide the alarm unit (area), alarm time, and alarm category. The information of the alarm unit (address, telephone, unit owner or contact person), the specific alarm point and what intrusion detector is used at that point. At the same time, there are early warnings that can be notified to the police, as well as reporting and eliminating cases after the police are dispatched, handling the storage of the results, and the time and details of handling the officers and officers. Complex systems often include linkage with electronic map GIS, linkage with GPS systems, and linkage with CCTV, access control, and patrol systems.

The anti-theft alarm system is generally composed of intrusion detectors, anti-theft alarm controllers and alarm control centers (hardware plus software). Its simplest form is the local (home, unit, etc.) alarm system. Its components are intrusion detectors and local alarm controllers, as well as audible and visual alarms (which can be either alarm controllers or external). The sophisticated anti-theft alarm system can have thousands of intrusion detectors. The alarm receiving system can be composed of anti-theft alarm controllers distributed in various regions (various regions) and alarming machines in the alarm center.

Anti-theft alarm controller environment adaptability requirements

1. Climate and mechanical environment adaptability The anti-theft alarm controller should be able to withstand the following environmental conditions: GB/T15211-1994 5.1 harsh level 4 high temperature environment; GB/T15211-1994 5.2 severe level 6 low temperature environment; GB/T15211 - In 1994, the 5.6 severe thermal environment of grades 4 (work) and 2 (life); GB/T15211-1994 5.4 Severe grade 1 (work), 2 (life) mechanical vibration environment: At the same time, the test function is normal, No leakage alarm and false alarm should be generated.

2. An electromagnetic compatibility-adaptive anti-theft alarm controller shall be able to withstand the harmful effects of the following electromagnetic disturbances: an electrostatic discharge disturbance of severity level 3 in GB/T 17626.2-1998; and a radio frequency electromagnetic field disturbance of severity level 3 in GB/T 17626.3-1998; GB/T17626.4-1998 Severe Class 3 Electrical Fast Transient Burst Interference; GB/T17626.5-1998 Severity Rating, Power Line Does Not Exceed 3, DC, Signal, Data, Control, and Other Input Lines Do Not Exceed 2 surge (impact) interference; GB/T17626.11-1998 severe level 40% UT 10 period voltage dips, 0% UT 10 cycles of short-term interruption of interference; at the same time, the test function is normal, should not produce Missing alarm and false alarm.

3. When emphasizing matters in combination with actual conditions, the following points must also be emphasized:

(1) At present, the climate and mechanical environment adaptability of the anti-theft alarm controller is a general requirement, and measures should also be taken for real harsh conditions such as high temperature, severe coldness, maritime nature (high humidity and heat), and chemical sites.

(2) Measures should also be taken when working under strong vibration and shocks.

(3) At present, the electromagnetic compatibility of anti-theft alarm controllers is also a general requirement. For lightning strikes, the areas with strong external electromagnetic interference need to be strengthened. Some products adopt measures and some product measures are too weak. We are designing such products. Should strengthen the protection.

(4) At present, the national standard GB12663-2001 only pays attention to the outside world's interference and influence on the anti-theft alarm controller, but does not notice the interference of the anti-theft alarm controller to the outside world, and pays attention to the interference to other equipment when composing the system, and What measures should be taken to reduce the impact. At the same time, attention should be paid to the external interference of the anti-theft alarm controller, especially the external cable of the keyboard.

(5) GB12663-2001 did not mention that the enclosure protection grade product should propose possible protection levels, and should indicate indoor, outdoor, high dust, strong rain and so on.
