The main functions of the intrusion
alarm host include: partition and zone, arming and disarming and alarming, event recording and querying, communication and networking, fault detection and display, password and reset, extension and compatibility, and other aspects.
1. Partitions and defense zones: It is generally advocated that alarm hosts with a medium or higher scale should establish partitions to facilitate management. The mainframe can even have multiple partitions, and the number of defense zones included in the partition can be determined by program design.
There are various types of defense zones, such as entrance and exit delay zones, perimeter zones, internal zones, emergency zones, medical rescue zones, fire zones, etc.; zones have various attributes such as sound/silence, continuous sound/intermittent Sound, Bypass/Unbypass, Wireless/Wired, Transmission Delay/No Delay, etc.
The number, types, and attributes of defense zones are suitable to meet the needs, and not necessarily the better. In fact, some hosts in foreign countries have many types of defense zones, but some are not suitable for domestic needs, but they are a burden to the senses. And inconvenience.
In order to facilitate memory and use, some mainframes can use partitions, zones, and even entrances and exits with a custom code or alias. For example, if several departments of a company occupy different partitions, each partition can be represented by a different department name. .
2. Closing and disarming and alarming: The type of arming and disarming, including left and right arming and disarming, out-of-office arming and disarming, automatic arming and disarming, forced arming and disarming, single-area arming and disarming, project arming and disarming (for testing), and setting up zone bypass and release, etc. The more complete the type, the more convenient the user.
There are two types of alarms, one is an intrusion triggered alarm; the other is a variety of detection fault alarms, such as tamper, power supply, sirens, zone faults, and telephone line faults. This kind of alarm involves self-protection of the host and should be taken seriously.
3, the event records and inquiries: All the host computer in the course of the operation of the police, as well as related to changing the set of various operations, should be stored as an event, when needed, but also can be easily viewed. This kind of event record does not allow arbitrarily revise, and even if the host is powered off for a long period of time, its record can still be completely saved. This kind of record is of great significance to the inquiry of responsibility and the lessons learned after major changes.
4, communication and networking: including compatible communication protocols, communication objects and directions. Wired telephones are generally used as the main means of communication. They can be networked with two or more centers. They can also report alerts directly to subscribers. Some hosts also added network or mobile communications as backup and assistance, further improving the reliability of communications.
In order to save telephone charges, some hosts may deploy and disarm private phones by default. In the case of hands-free telephone sets, the center can determine the user account for arming or disarming based on the telephone number transmitted by the other party. However, this function must be obtained. Center receiver support.
5, fault detection and display: with the nature of automatic maintenance, usually AC and DC power monitoring, tamper, alarm loop, loop circuit failure, telephone line failure, communication failure and so on. The more complete this function, the better the host self-protection performance and the higher the reliability of the work. The display method after a failure occurs, and for the LED display, the meaning of the acousto-optic display is required to be clear and easy to understand and remember.
6, password and reset: Common types of passwords are engineering passwords, administrator passwords, user passwords, hijacked passwords, and some can also set a one-time password, a single deployment password (armed effective, disarmed invalid) and remote program design password.
The host should have the function of resetting, in the case of lost passwords or other special circumstances, by resetting, restoring the factory settings or reprogramming. For mainframes, due to the large amount of program design content, the reset is often divided into several levels. Partial reset can be performed specifically for a certain aspect to reduce the workload of program redesign.
7. Extension and compatibility: The expansion of host functions is generally accomplished through the connection of modules, such as the increase of defense zones, the compatibility of wireless zones, the increase of programmable output, and the connection with access controllers. These functions are very popular in the special occasions to meet the individual needs of users.
