Which type of building intercom alarm system is more suitable for users

Reliable communication guarantee

The alarm signal received by the building intercom alarm module must be reported to the management center in a reliable manner. No false alarms, especially missing reports, can occur to ensure that the alarm is successful.

Alarm information confirmation: Is the alarm part of the building intercom alarm signal received and sent to the management center? The central alarm information confirmation mechanism must be established. After the management center receives the alarm information, it shall send a confirmation signal to the alarm host to indicate that the center has received it, and the building video intercom alarm host shall retransmit if it does not receive the confirmation signal;

Alarm information check: The alarm data and the building intercom communication data share the data line and the management center network. Complex circuit problems and communication conflicts (alarm and building intercom information) may cause alarm information error. The communication information must be corrected. Inspection (such as CRC, verification, etc.), the management center checks the information, and errors are reissued;

Communication interception: The alarm information adopts the active sending mode, and the communication line is intercepted before sending to avoid data rear-end phenomenon and ensure that the communication is successful once.

Rich communication protocols

A good alarm host must have a rich scientific communication protocol, and a host that can only alarm and communicate is still a long way from practical requirements. For example, the internationally popular Ademco4 2 and AdemcoContactId alarm communication protocols are relatively complete and scientific. However, in civil affairs, many communication contents can be saved, but the following items have special significance.

The host disarms the defending function: When the occupant disarms the building intercom alarm, the alarm should report the status to the management center, which has special significance.

The use of alarms by tenants may cause disputes. For example, if someone else fails to arm the system for reasons, resulting in loss of property, it may warn about the failure of the alarm system and request a claim. At this time, the management center can query the user to confirm the release of the defense record. This kind of case appeared in reality in many cases; the management center can also monitor the status of important user hosts in a timely manner, and even the management center can take the initiative to disarm the occupants.

Self-inspection function: The alarm system belongs to a product that is not afraid of 10,000 and is afraid that it will happen in the normal use. However, in case of alarm, it is necessary to ensure that the alarm is successful. It is difficult for tenants to think that they know that the alarm is normal or not. The design of the alarm should have a self-check function. The results of the self-inspection should be regularly reported to the management center and be monitored by the management center. The faults should be maintained immediately. Intercom manufacturer

The center actively withdraws the defense function: What should I do if I stay out and forget to arm? In the case of authorization, the management center may send an order to arm the resident host to avoid unnecessary losses and reduce the occupant's trouble.

Integrated design with building intercom

The alarm host is integrated with the indoor building intercom host to ensure that the user's operation is more convenient, the integration is high, and the construction is also introduced. The following items deserve attention in the design.

Modular design: Modular design not only brings convenience to the manufacturer, but also suits the actual needs. As a basic component, the building video intercom is installed in the residents' homes. Generally speaking, it is once in place, and the alarm module is specifically installed according to the user's requirements. Modular design can be flexibly applied to this model, reducing the intellectual investment, and the engineering company is willing to accept it.

Unified cabling: The cabling of the building intercom and alarm system is integrated and connected to the wiring board of the indoor building intercom host. From the non-visual - visual - alarm no need to re-wiring, easy system upgrades.

One-touch design: Building intercom and alarm systems can share the same data line (two-wire 485 bus), reducing the amount of wiring, and facilitating the integration of the center system. However, to solve the problem of conflict between a large number of building intercom and alarm information on a single line, it is necessary to formulate a reasonable communication protocol.

Humanized operation design: The daily operation of the alarm system (disarming, emergency alarms, etc.) must be oriented to users at all levels. For example, if you use push-button operation as much as possible, you must have a clear indicator light and a horn prompt. If possible, use a remote control to focus your daily operations on the remote control. The control panel is completely transparent to the user.
