What equipment does the building intercom system consist of?

The building intercom system is mainly composed of host, extension, UPS power supply, electric lock and door closer.

The host computer is the control core part of the building intercom system, and the transmission signal and electric lock control signal of each extension are controlled by the host computer.

Extension is a kind of walkie-talkie, which usually talks to the host, but now it is merged with the building intercom system of the host to form an internal telephone system, which can complete the telephone contact of all users in the system.

The function of UPS power supply is mainly to keep the building intercom system from power failure. Under normal circumstances, it is in a charging state. During power failure, UPS power supply is in the state of supplying power to the system.

The internal structure of electric lock is mainly composed of electromagnetic mechanism. Users can press the electric lock key on the extension and use the electromagnetic coil to electrify, so that the electromagnetic mechanism drives the connecting rod to move and control the opening of the gate.

Door closer is a special automatic door closing linkage mechanism. It has a regulator, which can adjust the acceleration and strength, and is convenient and flexible to use.

Mode of operation

The door of the building is always locked at ordinary times to prevent people who are not in the building from entering the building without permission, and residents in the building can freely enter and leave the building with their keys. When guests visit, they need to press the room number of the visited household on the intercom keyboard outside the building door and call the intercom extension of the visited household.

The owner of the visited household makes a two-way call or visual call with the visitor through the intercom equipment, and confirms the identity of the visitor through the voice or image of the visitor. After confirming that visitors can enter, the owner of the household uses the unlock button on the intercom extension to control the electric door lock on the entrance door of the building to open, and the visiting guests can enter the building. After the visiting guests enter the building, the door of the building locks automatically.

The security department of residential property management can monitor the work of the security intercom system of each residential building in the residential area through the security intercom management host. If the entrance door of a residential building is illegally opened and the security intercom host or line fails, the community security intercom management host will send an alarm signal and display the alarm content and location.

The system can be used for communication between residential property management departments and households or between households. For example, the property department informs residents to pay various fees, residents inform the property management department to maintain the facilities in the community, and residents report to the community or neighborhood Committee managers for help in case of emergency.
