- Instruction manual - 1 piece.
- Canopy for protection from precipitation - 1 pc.
- Rotating bracket 30 degrees - 1 pc.
Installation and connection of AVC-305 COLOR
In order to install the calling panel, it is necessary to perform the following operations:
- decide on the installation location (fixed door leaf or wall)
- drill holes for mounting
- lay a communication line for connection (avoid laying near power cables)
- connect the calling panel to the communication cable according to the instructions
- test the correct operation of the video intercom and calling panel
- screw the calling panel in a pre-prepared place
- plug the holes on the calling panel with decorative plugs.
Attention! It is not recommended to install the calling panel on the moving part of the door to avoid damage to the built-in video camera.
There are 6 wires on the back of the calling panel, 2 of which are intended to transmit a signal to open the lock, and the rest are for connecting the AVC-305 COLOR calling panel to the video intercom. Most calling panels use a 4-wire connection scheme. For convenience and ease of installation, all wires are highlighted in different colors; the Activision AVC-305 COLOR calling panel should be connected according to the diagram:
Black (general)
Red (+12V)
Yellow (audio)
White (video)
As can be seen from the connection diagram, the panel is powered from the video intercom. The maximum length of the line from the video intercom to the calling panel declared by the manufacturer is 50 meters. In practice, it was possible to achieve a line length of up to 100m, but only when using an RG-6 cable in combination with a 2x1.5 cable. For short distances up to 15 meters, we recommend using UTP 5-e twisted pair cable due to its low cost.
Video review of AVC-305 COLOR
This article will discuss connecting a video intercom for a private home using the AXIOS video intercom system as an example. This system consists of the AXI-305 NEW calling panel and the AXI-LA 04 subscriber device (video monitor), to which an automatic lock from any manufacturer is connected.
Layout of video intercom devices
A typical layout of video intercom devices is shown in Figure 1.
Rice. 1. Typical layout of video intercom devices with one calling panel
As can be seen from Figure 1, some of the system’s devices are installed inside the house (subscriber device and power supply), and some of the devices are installed on the gate (calling panel, lock control unit and automatic lock). Devices inside and outside the house are connected by a communication line through which power is supplied and video and audio signals are transmitted, as well as calling and control signals.
What you need to install a video intercom
Tools and materials
To perform installation of a video intercom, the following minimum set of tools is required:
- A hammer drill with a set of drills and blades for chipping walls;
- Drill or screwdriver;
- Angle grinder;
- Screwdriver set;
- Pliers;
- Hammer;
- A container for mixing putty and a spatula.
The list and quantity of materials used depends on the method of laying cables, the distance and placement of actuators and other equipment. The following materials are most often needed:
- Two-core wire for power supply. It is necessary to connect a power cable with a cross-section of 2x2mm to the lock or use a BUZ;
- ShSM (wire for video intercoms and alarm systems) or KVK-P-3 (combined cable for video surveillance) or, as a last resort, shielded twisted pair (UTP wire);
- Sockets and plugs;
- Corrugated electrical pipes;
- Plaster, alabaster or putty.
Link
Communication line requirements
- Twisted pair UTP Cat 5 4x0.2 mm2 - up to 28 m;
- Twisted pair UTP Cat 5 (AWG 22) 4x0.3 mm2 - up to 50 m;
- Wire 4x0.5 mm2 - up to 80 m.
Rice. 2. Maximum communication line length depending on cable type
However, practical experience in installing intercom systems has shown that twisted pair cables provide acceptable communication quality only if its length does not exceed 10 meters! Otherwise, the video image suffers primarily due to interference and interference. In most cases, it is better to use specialized shielded cables for video surveillance or alarms in the communication line. For example, ShSM or KVK-P-3.
Installation and connection of the calling panel
The calling panel should be mounted primarily on fixed building structures: the wall of a house or a permanent gate post. It is strongly recommended not to install the device on moving devices - gates, gates or doors, as constant shaking can dislodge the lens inside the housing. Given the miniature size of the lens, even a small shift can become critical.
To prevent the lens from being illuminated by sunlight, it is necessary to use a sun visor or a corner-mounted bracket that is installed under the calling device and changes its viewing angle.
Rice. 3. Call panel with sun visor or corner bracket
Otherwise, sunlight may backlight visitors and only the silhouette will be visible on the screen, not the face.
Installation of the video intercom panel is carried out in the following order:
- The back cover is removed from the calling panel; . Drilling locations are marked through the mounting holes;
- All marked places are drilled and an additional through hole is drilled to lead the communication line wires and lock control into the yard;
- The communication line is connected to the contact strip of the calling panel in accordance with Fig. 7 and is brought into the house to the subscriber device;
- The wire running into the yard to control the lock is connected to the contacts of the electromechanical lock.
- Devices should only be connected to the network after all electrical connections have been completed.!
After checking all connections, the calling panel is attached to the base with special “secret” screws, which cannot be removed with a simple screwdriver.
Installation and connection of the lock
To open the lock, a voltage of 12V is required, which comes from the calling panel. There are two schemes for installing a power supply unit (PSU) in an intercom system:
- The power supply is installed in the house, the supply voltage comes through the communication line;
- The power supply for the subscriber device is installed in the house, and to power the calling panel and the lock, a second power supply is installed in close proximity to them.
The advantage of the first scheme is that only one power supply is used in the system. However, in a communication line the cross-section of the wires is small and, as the length of such a line increases, the DC voltage drops. In the case of an electromechanical lock, this voltage may not be enough to trigger its electromagnetic coil. Thus, in addition to the communication line, a powerful power cable with a minimum cross-section of 2mm2 must be installed to the lock. Especially if the lock is located more than 20 meters from the intercom. Or use a lock control unit (LCU) - this is a small-sized device that accumulates a 12V voltage from the communication line and gives a short current pulse (up to 3A) sufficient to open an electromechanical lock. The miniature dimensions of the BUZ allow it to be placed both in the calling panel body and in the lock body.
Installation and connection of the subscriber device
To avoid interference and interference, the subscriber device should be installed no closer than 30 cm from electrical lines.
Rice. 5. Installation height of the subscriber device
Rice. 6. Installation of the subscriber device on the wall
The device is mounted on a frame, which is attached to the wall using self-tapping screws and plastic dowels.
Please note the following:
- Disconnect the monitor from power supply before installation.
- Avoid sharp impacts and falling equipment!
- Connect devices to the network only after all electrical connections have been completed!
Switching of all video intercom devices
When using one calling panel, you must connect it to the “Panel 1” monitor connector. Observe the matching colors and purpose of the connecting wires of the monitor and panel (Fig. 7). If you use an additional calling panel, it should be connected to the “Panel 2” connector.
Rice. 7. Connection diagram of calling panels to the subscriber device
The “Panel 1” and “Panel 2” connectors have the same functionality (Fig. 7).
Purpose and colors of wires:
- Red: +12V
- White: Audio signal
- Black: Ground (GND)
- Yellow: Video signal
The electric lock is controlled using the normally open relay contacts (N.O.) of the calling panel.
The subscriber device is powered from an alternating current network with a voltage of 100...240V. The device is equipped with its own voltage converter.
ATTENTION! When connecting, observe the purpose of the connecting wires between the monitor and the panel.
After switching of all connections is completed, the operation of the intercom system is tested, and only after this the final installation of all units of the system is carried out.
