In order to deal with theft and robbery, the anti-theft alarm system design is a systematic project, and it is a complicated project. Therefore, its construction should follow the basic procedures of the project.
Due to the variability of the external conditions of the burglar alarm system, it is impossible to use the traditional method of intuition and the experience of the individual. In order to ensure the integrity of the system, it is necessary to consider the problem in order to optimize the design of the anti-theft alarm system. .
The burglar alarm system is an important system in security engineering. The design should follow the following:
(1) The anti-theft alarm system shall be composed of a human intrusion detector, transmission system and control equipment, and shall be attached with a sound, image (or both) review device (monitoring device).
(2) The anti-theft alarm system shall have the alarm function of theft and robbery, and have the means of communication for directing the police force of the dispatching station. The preventive capability shall be consistent with the requirements of the design task.
(3) The design of the anti-theft alarm system must be carried out in accordance with the relevant national regulations. It must be designed in conjunction with the physical protection system and the situation of the police force.
(4) The design of the anti-theft alarm system should be carried out on the basis of on-site investigation.
(5) The transmission system should generally transmit the alarm information from the dedicated line, and be equipped with the necessary wired and wireless switching devices to form an alarm transmission system with wired transmission as the main and wireless transmission as the supplement. It is not suitable for the area with wired transmission. And parts, should be wireless transmission.
(6) The selection of equipment and circuit laying methods should meet the precautionary requirements, meet the environmental conditions of use, and have appropriate performance and price ratio.
(7) The selected equipment and equipment must be at least the commodity inspection certificate for the imported equipment and equipment that meets the safety standards of the relevant national technical standards and has passed the inspection of the national designated testing center.
(8) The system design should take into account the possibility of further development of the system, which should be conducive to the expansion of the system scale and the reference of new technologies.
(9) The system should consider convenient installation, convenient configuration and convenient use.
(10) The system itself has strong security and confidentiality.
(11) Within the protection zone, the distance between the edge of the blind zone of the human intrusion detector and the protection target shall not be less than 5 m.
(12) The outdoor detection and transmission system should consider the anti-lightning interference measures adapted to the local specific conditions and the ability to work normally under natural environmental conditions.
(13) The selected equipment and equipment must meet the safety standards of relevant national technical standards, and the imported equipment and equipment that have passed the inspection of the national designated testing center shall have at least a commodity inspection certificate.
(14) The outbound population for internal staff should be equipped with an access control device that automatically identifies the identity.
(15) Fixed-mounted wireless alarm transmitting devices shall have a tamper-proof alarm and a physical protective casing to prevent vandalism.
(16) The security defense system consisting mainly of the wireless alarm networking mode should have the function of monitoring the used channel. When a continuous blocking signal or interference signal exceeds 30S, which is enough to hinder the normal reception of the alarm signal, the receiving end should A fault signal is displayed.
(17) The security defense system consisting mainly of wireless alarm networking mode, the receiving end should have the function of receiving and processing multiple simultaneous alarms, and no leakage alarm should be generated.
(18) Doors and windows should be equipped with switch-type alarm devices or other alarm devices.
(19) The central control room should be able to immediately identify the location, nature (robbery, theft, fire, fault, etc.) while receiving the alarm signal, and display the print record and store the alarm time, location, nature and disposal plan on the screen.
(20) The battery used by the transmitter shall be valid for not less than 6 months. When the undervoltage alarm signal is issued, the power supply shall be able to support the normal operation of the transmitter for 7 days.
(21) The installation position of the receiver shall be determined by field test to ensure that an alarm signal from any transmitter in the guard area is received.
(22) The system design should take into account the possibility of further development of the system, which should be conducive to the expansion of the system scale and the reference of new technologies.
(23) The system should consider convenient installation, convenient configuration, convenient use, and the system itself has strong security and confidentiality.
