In general, the design of anti-theft alarm systems should pay attention to the following aspects, which are clearly required in the relevant alarm system standards or related standards.
1), system design should be standardized and practical
The design of the anti-theft alarm system must be based on the actual investigation of the site, and the design should be based on factors such as environmental conditions, objects of prevention, investment scale, maintenance, and methods of receiving and handling the police. The design of the system should meet the requirements of the relevant risk level and protection level standards, as well as the management and use requirements of the relevant design specifications, design mission statement and builder. Equipment selection should meet the requirements of relevant national standards, industry standards and relevant management regulations.
This point has higher requirements for units engaged in the design of anti-theft alarm systems. At present, many units have not done enough on this point.
2) Pay attention to the advancedness and interchangeability of the system according to the standards
The design of anti-theft alarm system should be moderately advanced and interchangeable in technology, leaving room for system expansion and / or modification.
According to our work experience, the general system should have 20% redundancy.
3) The accuracy of the system
The anti-theft and intrusion alarm system should be able to accurately and timely detect intrusion behaviors and send out alarm signals; the sources of intrusion alarm signals, anti-demolition alarm signals, and fault signals should have clear and obvious instructions
The intrusion alarm system should be capable of sound review, and the intrusion alarm system project linked with the TV monitoring system should be able to perform sound review and image review at the same time.
It is important to point out that the anti-theft alarm system does not allow leak alarms.
4). System integrity
The system should take precautionary measures against all paths in the intrusion fortification area, and strengthen preventive measures against the weak links of physical protection that may exist on the intrusion path. There shall be no blind spots within 5m of the protected object.
With regard to integrity, it is now more of a problem. We found in daily acceptance and inspection that many alarm systems have many loopholes. The key is the lack of integrity in design. Regarding the solution of this problem, it is necessary to rely on the technical designers' full understanding of the standard content and the accumulation of rich alarm engineering experience.
5). Depth protection of the system
The design of the intrusion alarm system should adopt a deep protection system. According to the risk level and protection level of the protected object, the entire defense area should be fortified at different levels and levels. A complete defense zone shall include four different types of defense zones, including perimeter, surveillance zone, protection zone and restricted zone, and different protection measures shall be taken against them.
A control center shall be set up in the protection zone, and one or more sub-control centers may be set up if necessary. The control center should be located in the restricted area, at least in the protection area.
With regard to the understanding and application of this point in the standard, managers need to pay sufficient attention. At present, the issue of depth has been noticed in the prevention of the Wenbo system, bank vaults, and surrogates. However, in other respects, the depth of the alarm system is relatively lacking, and many of them are isolated and lack of hierarchy.
6), linkage compatibility
The anti-theft alarm system should be able to link with the TV monitoring system and the entrance control system. When joint design with other systems, system integration design should be carried out, and each system should be compatible with each other and work independently. Anti-theft alarms are second only to fire alarms.
Several aspects that need to be paid attention to in the design of anti-theft alarm system
The design of the alarm system is very important. Now we find that many units have not carried out serious on-the-spot investigations when constructing and using the anti-theft alarm system, and have not carried out effective design in combination with the on-site environment. Of course, the alarm equipment is selected and installed. Of course, this is a worthy of attention in the promotion and application of anti-theft alarm system Aspect.
