In general, the anti-theft alarm system design should pay attention to the following aspects, which are clearly required by the relevant alarm system standards or associated standards.
First, the system design should be standardized and practical
Anti-theft alarm system design must be based on the actual survey of the site, according to the environmental conditions, the object of prevention, investment scale, maintenance and access to police and other factors to design. The design of the system should meet the requirements of the relevant risk level and protection level standards, and comply with the relevant design specifications, design assignments, and construction and management requirements. Equipment selection should meet the requirements of relevant national standards, industry standards and relevant management regulations.
This point has a higher requirement for the design units engaged in anti-theft alarm systems. At present, many units have not done enough.
Second, we must pay attention to the advanced nature and interchangeability of the system according to the standards and regulations.
The design of the anti-theft alarm system should be technically advanced and interchangeable, leaving room for system expansion and/or retrofitting.
According to our work experience, the general system needs to have 20% redundancy.
Third, the accuracy of the system
The anti-theft intrusion alarm system should be able to accurately and timely detect intrusions and issue alarm signals; there should be clear and obvious indications of the source of intruder alarm signals, tamper alarm signals, and fault signals.
The intrusion alarm system should be capable of sound review. The intrusion alarm system engineering linked with the television monitoring system should be able to perform sound review and image review at the same time.
It is necessary to point out in particular that anti-theft alarm system does not allow leakage alarm.
Fourth, the integrity of the system
The system should take precautionary measures against all paths in the intruded and fortified areas, and strengthen preventive measures against possible weak points for physical protection on the intrusion path. There should be no blind spot within 5m of the protected target.
On the integrity issue, it is now more of a problem. We found in daily inspections and inspections that many alarm systems have many loopholes. The key is the lack of completeness in design. To solve this problem, it is necessary to rely on the technical designers to fully understand the standard content and accumulate rich experience in alarm engineering.
V. System's depth protection
The design of the intrusion alarm system should adopt a deep protection system, and the entire prevention area should be subject to sub-regional and hierarchical defense according to the level of risk and level of protection of the object to be protected. A complete zone should include four different types of zones: perimeter, surveillance zone, protection zone, and exclusion zone. Different protective measures should be taken for them.
A control center shall be set up in the protection zone, and one or more sub-control centers may be established if necessary. The control center should be located in the restricted area and should be at least in the protected area.
With regard to the understanding and application of this point in the standard, managers need to pay sufficient attention. At present, attention is paid to depth issues in the prevention of cultural and art systems, bank vaults, and depository vaults. However, in other aspects, the emphasis on the depth of the alarm system is relatively lacking, and many of them are isolated and lacking in level.
Sixth, linkage compatibility
The anti-theft alarm system should be able to interact with the TV monitoring system, entrance and exit control systems, etc. When designing in conjunction with other systems, system integration design should be carried out. Each system should be compatible with each other and work independently. Anti-theft alarms are second only to fire alarms.
