The main functions of the intrusion alarm host include: zoning and defense zones, deployment and alarm, event recording and querying, communication and networking, fault detection and display, password and reset, expansion and compatibility, and many other aspects.

1. Zoning and defense zones: It is generally advocated that alarm hosts of medium or above scale should be set up with zones to facilitate management. Large hosts can even have multiple zones, and the number of defense zones included in the zones 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 assistance zones, fire zones, etc; The defense zone also has various attributes, such as sound/silence, continuous sound/intermittent sound, allowed/not allowed bypass, wireless/wired, transmission delay/no delay, etc.

The number, type, and attributes of defense zones should meet the needs, and not necessarily the more the better. In fact, some foreign hosts have a wide variety of defense zones, but some are not suitable for domestic needs, which may cause burden and inconvenience.

For the convenience of memory and use, some large hosts can use custom codes or aliases to identify partitions, defense zones, and even entrances and exits. For example, several departments of a company occupy different partitions, and each partition can be represented by different department names.

2. Deployment and alarm: The types of deployment and removal include left behind deployment and removal, outbound deployment and removal, automatic deployment and removal, forced deployment and removal, single defense area deployment and removal, engineering deployment and removal (for testing), setting up defense area bypass and removal, etc. The more comprehensive the types, the more convenient the user is.

Alarm can be divided into two categories: one is intrusion triggered alarm; Another type is various fault detection alarms, such as tamper proof, power supply, alarm signal, zone failure, telephone line failure, etc. This type of alarm involves the self-protection of the host and should be taken seriously.

3. Event recording and querying: Any alarm situation that occurs during the operation of the host, as well as various operations related to changing settings, should be stored as an event and can be easily viewed when needed. This type of event record cannot be arbitrarily deleted or modified, and even if the host is powered off for a long period of time, its record can still be fully saved. This type of record is of great significance for responsibility inquiries and lessons learned in the event of significant changes.

4. Communication and networking: including compatible communication protocols, communication objects and directions. Generally, wired telephone is used as the main communication method, which can be connected to two or more centers, and can also directly report alarm situations to users by phone. Some hosts have also added network or mobile communication as backup and auxiliary, further improving the reliability of communication.

In order to save on phone costs, some hosts can default to deploying or disarming dedicated phones. In the case of a hands-free phone, the center can determine the user account to deploy or disarm based on the phone number transmitted by the other party. However, this function must be supported by the center receiver.

5. Fault detection and display: With the nature of automatic maintenance, it usually includes AC/DC power supply monitoring, anti disassembly, alarm circuit, zone circuit failure, telephone line failure, communication failure, and other contents. The more comprehensive this feature is, the better the self-protection performance of the host, and the higher the reliability of its operation. The display method after a malfunction, for LED displays, it is required that the meaning of the sound and light display is clear, easy to understand and remember.
