Intercom visit - operating instructions. Intercoms are an effective access system, which is found both in multi-storey buildings and in enterprises, offices, private cottages and other premises where access control is needed. The equipment protects property and territory from penetration by third parties, and also allows you to determine who plans to enter the building while inside.
Against the backdrop of the rapid growth in popularity of Visit intercoms, instructions for setting up and connecting devices in an apartment building have become extremely popular.
general information
Currently, the VIZIT Group holding consists of several enterprises that specialize in the development, implementation and maintenance of access control and management systems under the more well-known Visit brand. The NPF MODUS-N trademark is responsible for the marketing and promotion of equipment, and given the sales volumes, the products are in demand not only in Russia, but also in other CIS countries.
The main advantages of the manufacturer include:
- A wide range of models with different technical characteristics.
- Operating temperature range from -40 to +45 degrees Celsius.
- Integration of advanced technologies and protective equipment.
- Development of advanced software solutions.
The listed items are present in each Visit intercom model. In addition, they are confirmed by hundreds of positive reviews and official certification by government quality control authorities.
Basic models: their purpose and features
Before connecting the Visit intercom handset, you should clarify its model and the specifics of connection with the other components of the complex.
The company's model range includes several generations and series of access devices. They differ in modifications, permissible number of connections, protection standard and purpose. The standard classification is as follows:
- The SM and N line is intended for use by a group of up to 100 people. It is found in multi-storey buildings and is represented by the following models: SM101T, SM101R, N101RTC (intercoms are supplied without cameras). The editions are equipped with backlit keys and can handle 600 keys. The series also includes an improved model N201FCP with a camera and connection for up to 200 subscribers.
- BVD300 includes several models (BVD306b, BVD310, BVD 313, 314, 316). The devices are capable of working with different numbers of users and have extensive functionality. The latest models 313, 314, 316 and 323 are designed for private homes and offices. At the same time, they can be installed in multi-apartment premises, taking into account the individual needs of consumers.
- 400 Comfort. An advanced line of intercom systems, which is used primarily in offices, apartment buildings and enterprises. The equipment works with 200 subscribers (depending on the configuration).
Intercom design
To understand the operating principle of the intercom and the features of independent connection and configuration, it is necessary to clarify the internal structure of the system. In essence, such an invention is a special means that limits or provides access to an object. The device has become extremely popular relatively recently, since previously code technology was used to protect entrance doors.
Vizit intercoms for an apartment or private house include several components:
- Subscriber device (handset). The device is located in the apartment and allows the owner to answer a guest’s call and decide whether to open the door or ignore the request. By default, the tube is combined with a locking mechanism.
- Call block. Used to enter the required code combination. The outer panel has different designs: with dialing buttons, with a reading platform that processes codes from keys or cards, with backlighting and even visual support. The last modification is not too common and is found in particularly protected facilities.
- Video camera (if we are talking about a video intercom).
- Locking mechanism. Allows you to control access to the building, because locks the door leaf. Modern intercoms are produced with electromagnetic, less often electromechanical locks. The first type can be opened from the outside, but it is much more reliable than designs with a metal latch.
- Switch. Responsible for transmitting data from the calling unit to the subscriber. A similar device is found in multi-subscriber intercoms, since single-user models do not require signal distribution.
Among the auxiliary means and accessories in the Visit intercom circuit, a video camera and a special monitor can be used to display the picture. Such systems are more reliable and functional, since in addition to audio contact, visual monitoring of what is happening at the door is provided.
How to connect a video intercom in a private house or apartment
Have you decided to connect a video intercom yourself? Then this article is for you. I'll tell you how to connect audio and video intercoms, as well as all related equipment. This article is divided into two large sections. The first describes all the components, the second provides connection diagrams.

Intercom system. Basic elements and their features
Monitor/audio tube and calling panel
The video intercom monitor can be:
- Analogue, working with CVBS cameras and calling panels. Despite the low quality of the picture (but sufficient to recognize the guest), this is the most common type of intercom.
- Analog HD, which, in addition to CVBS, also supports HD-TVI, HD-CVI and AHD cameras and calling panels. In this case, video resolution can reach 2 MP (1080p). This is clearly redundant for intercom purposes, but for the task of recording video it will be just right.
- IP. The main advantage is the use of network technologies to connect the monitor with the calling panel, which means any distances between them. Various extension cords, wireless points, fiber optics and the Internet will allow you to connect devices even a kilometer away from each other.
As for the characteristics of monitors, it is worth paying attention to the number of supported calling panels, CCTV cameras, memory cards, and the ability to install several monitors in one system. An additional feature is the ability to forward calls to a smartphone. The latter is available not only in IP intercom, but also in analogue too. For analogue ones, the manufacturer can add a network port and/or Wi-Fi module to connect the monitor to the calling panel.
In some cases, you can completely abandon the monitor. The market offers calling panels with the ability to connect to the Internet and call forwarding to a smartphone.
In terms of compatibility - you can often connect calling panels from any manufacturer to analog and analog HD monitors, just check the standard supported by the monitor (CVBS, TVI, CVI, AHD) and resolution. However, I highly recommend using equipment from the same manufacturer, as compatibility problems occasionally arise - the door does not open, there is no sound, there is no call. Or check the equipment on the table before installation. In IP intercom you should use equipment from only one manufacturer.
As for the audio intercom, it is worth considering that the handsets can be for multi-apartment intercoms (coordinate and digital), or they can be for single-subscriber calling panels. There may also be tubes that connect to the monitors discussed above. So before purchasing, either consult with the seller, or look in the instructions to see which calling panel the selected handset works with.
Switch (for IP intercom)
If you plan to use IP intercom and power all equipment via PoE (power transmission over Ethernet), then pay attention to the power standard supported by the monitor and calling panel. This can be either 802.3af, used in almost all PoE switches, or Passive PoE. Equipment with the latest power supply only works with switches from the same manufacturer.
Lock and closer
There are two types of locks - electromagnetic and electromechanical. Electromechanical ones open when power is briefly supplied, and electromagnetic ones, on the contrary, when power is removed. Accordingly, if your lights are turned off and an uninterruptible power supply is not provided, the electromechanical lock will remain in the closed position, and the door with an electromagnetic lock will open. Therefore, in addition to the electromagnetic lock, it is worth installing a regular lock that can be opened with a key.
An electromechanical lock can also be opened using a key, but to open an electromagnetic one you need to buy a reader and a controller (or buy an calling panel in which these elements are built-in). The closer must be installed on doors with an electromagnetic lock and, if desired, on doors with an electromechanical one.
Connecting Vizit intercoms
For the intercom system to work correctly, you need to connect it correctly. This is done strictly according to the manufacturer’s instructions and diagram.
In order for the intercom to work as long as possible, you need to follow the basic operating rules and maintain it on time. The timing of scheduled inspections is specified in the regulations and the contract with the service company.
How to connect Vizit to an entrance intercom
The Vizit UCP components are interfaced using an appropriate set of wires and switches. To carry out the work you need:
- Stretch the cable from the calling unit into the apartment to the handset.
- Register your apartment number in the device memory.
- Buy an adapter and configure it.
- Adjust equipment parameters.
Connecting a video intercom to a digital entrance intercom
For the proper functioning of such equipment, you need to buy a special component - an MSC interface module. It allows you to coordinate the video device with a digital intercom. The adapter is compatible with various types of equipment, including Visit models. According to the manufacturer, it works reliably and efficiently.
Installing the MSC adapter is quite simple. To do this, you need to connect the wires from the handset to it, and then connect it to the video intercom. The call block is connected like a camera.
Connecting to a coordinated entrance intercom
The MSC adapter is used for analog intercom systems. In this case, it is connected according to the instructions described above, and the detailed pairing diagram is as follows:
Changing your individual code
Setting up the equipment The visit is quite quick and simple. To change the lock opening code, you need to do the following:
- Press the combination #-999.
- After the double signal sounds, indicate the master code (1234 or any other).
- A successful change of parameters will be indicated by a single beep.
If you hear 2 beeps, you will have to repeat the action from scratch.
Self-installation rules
The intercom handset is presented as a multifunctional intercom device, thanks to which the property owner and his visitor can communicate. The main signal comes from the speaker and reaches the owner himself. In digital units, manufacturers have provided a two-core wire to which the intercom is connected. But in order to avoid the most common mistakes, you need to maintain a certain polarity.
In the internal compartment of the unit there are microcircuits that must be programmed accordingly. For these purposes, you can use a jumper or jumper. If you need to find out the code, when the technician will have to disassemble the device and examine the board.
The panel with numbers is most often located near the jumper. The code consists of numbers that correspond to closed jumpers. If the master has already taken on this work, then he needs to have an old collapsible structure in order to later assemble a new part using it.
Minor difficulties may arise with a coordinate matrix device, since such a tube has keys that consist of a “zero” and seven cores. To avoid the most common mistakes, you need to find tires of ones and tens. Practice shows that the initial cores are much easier to find in the panel (the same numbers in the apartment numbers). But to find the tires of the units, you need to go up one floor. The necessary element is located in the top panel. A novice master needs to remember that + is connected to tens, and - to units.
If a person understands that he cannot install the tube on his own, then it is better to seek help from specialists . In this case, you can count on fast and high-quality completion of all assigned tasks. In addition, a specialist can recommend the most suitable device model.
Major breakdowns and repairs
An intercom system is a complex and high-tech invention, so various malfunctions and malfunctions are not excluded. To minimize the likelihood of their occurrence, you should purchase equipment from official suppliers or trusted companies. You also need to know how to fix common breakdowns yourself:
- If the keys work correctly, but a reset occurs when dialing the subscriber's number, the connection may be lost. To do this, the serviceability of the BV-KM line should be assessed.
- If the call block does not respond to pressing. This happens when there is no power supply. To eliminate the failure, you need to evaluate the connection of terminals Y1 and Y2. Normal voltage is 13-18V.
- The lock cannot be opened with a key or button. This is usually due to problems with the power supply or the call block.
Results
Vizit intercoms are reliable devices that are characterized by stable operation in various conditions. However, troubles in the form of breakdowns still happen sometimes. If this problem does not pass you by, you can always try to fix the intercom handset yourself, based on the tips given above. Not confident in your technical knowledge and skills? No desire to take risks? It's better to contact service support. The technicians who service intercom systems will diagnose the device that has failed and identify the cause of the failure. In their work, they use special equipment to diagnose and configure intercoms. When it is known what exactly has stopped working, a qualified specialist will tell you what exactly needs to be done - repair the tube by purchasing new spare parts, or completely replace the device.
It is worth noting that the cost of the tube is low, so in case of serious damage, as a rule, experts recommend installing a new device that will work for a long time and without problems, without causing any inconvenience to the user.

- Recession of the tongue.
- Broken cable connecting equipment.
Expert advice
Before installing the purchased unit, be sure to determine the most suitable location. Experts recommend avoiding sockets, switches, switchboard boxes, and other objects that are powered by electricity. The technician must have a good understanding of exactly where the wires go. In the selected location, a two-core installation cable and a colored cable are inserted under the box. They must be laid all the way to the shield on the staircase.
During connection, horizontal position of the wiring is strictly prohibited , since the call simply will not come into the home. All elements must be screwed vertically to the wall. All modern handsets have two contacts and a wiring diagram. One side is connected to the contacts, but the other is connected to the panel in the entrance. Multi-colored wires are laid in a common house box.
To avoid the most common mistakes, you need to know not only the color of the cable, but also the apartment number. According to the desired color, the wire is connected to the switch. After all these manipulations, all that remains is to check the functionality of the unit. The system must work flawlessly to ensure the safety of residents of an apartment building.
