Building intercom system basic knowledge

As such products, Brauns has a single network cable connection, households are not afraid of short-circuit isolation, no indoor power supply, no power consumption in standby, no special video line, high stability, reliable performance, easy maintenance and so on.

The building intercom system is equipped with anti-theft six at the door of each unit, the administrator of the district master control center, and the intercom host of building entrances and exits. Electronic control locks, door closers and visual intercom extensions in the user's home are made up of dedicated network cables.

In order to realize the intercommunion between the visitor and the resident, the resident can remotely open the security door and each unit ladder visitor can call the resident through the intercom host, and the other party can enter the building after agreeing, thereby limiting the entry of illegal persons, and at the same time, if the occupants are robbed at home. Or sudden illnesses can be notified to security personnel through this system to get timely shake and handling.

The optional building intercom system should be selected according to different residential structures, community distribution and functional requirements. Some of them are suitable for non-enclosed residential buildings, which can implement the functions of call, intercom and unlock, and have a luminous indication function. Suitable for low-rise or high-rise residential structures, closed management of the community can choose to use an indoor unit with security alarm function, users can install the door magnet according to their needs. Infrared probe, smoke alarm. Gas leakage alarm device.

In order to take into account the needs of different users and economic conditions, the color and black and white extensions in the visual system are compatible. Users can use color machines or black-and-white machines. Intercom indoor units without visual function can also be used to facilitate the project wiring. According to the no longer cell distribution, the large system bus can use star type wiring and ring type wiring.

In order to completely solve the large-system signal attenuation, video signal amplification can be performed on the same cable with dual-phase 舆 double-entry, and the closed-cell community can also be configured with a management center. The management center can store alarm records and can access the alarm at any time. Type, time and alarm number of the building's building and room number, the central machine can monitor and call the entire community and Loudong door.

Therefore, the use of building intercom systems must be selected according to the characteristics of their own residential area, must not be blind, in order to achieve the highest performance-cost ratio, to maximize the function of this system.

A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
