Installation of SCS for a small firm engaged in all office building. Testing SCS lines Estimated Example of estimates on SCS and LAN

The structured cable system is one of the most important elements of the infrastructure of any modern organization. This is a single system that combines all corporate computer devices, local networks, cables, office equipment, etc. Components.

Therefore, the installation of the SCS should be carried out exclusively by professionals, in accordance with all standards established at the state level. Testing is the final installation procedure, and is carried out in order to confirm the quality of the system before putting it into operation.

In the process of testing SCS lines, ultra-precise modern technical devices are used, allowing to detect the slightest problem in the operation of the system, to further eliminate and prevent re-occurrence. Experts also explore all aspects of the system functioning in each of the possible operational modes.

Thus, the testing of lines ensures reliability, stability and high quality of the operation of the SCS. In the case of a critical problem or emergency, specialists based on data obtained as a result of testing will be able to restore the good operation of all system components.

According to the results of the testing of lines, the client receives a warranty on the established system, the validity of which is several decades. The system is assigned a corresponding category, and its compliance is confirmed approved.

How is the testing of the SCS SCS lines?

The price of testing SCS lines is determined on the basis of the estimate, which includes all aspects affecting the final cost. The final cost is determined on the basis of a number of individual criteria:

• types of work performed by specialists;
• need to test ports;
• categories assigned to the system;
• number of lines;
• architecture and branching system;
• location of the object;
• building area;
• availability of readable marking;
• the presence of the location scheme of jobs.

Also, the estimate includes the correction of the hidden and visible disadvantages of the system, in case of detection, and other additional operations. In the process of testing lines, there may be necessary to call them, urgent troubleshooting, equipment replacement, etc.

All additional operations are pre-coordinated with the client, and are included in the estimate only by his desire. The estimation includes and checking the system in real operating conditions, to detect negative environments (also at the request of the client).

We offer highly qualified testing of the SCS, using the most modern equipment, at the most competitive prices. Contact: 7 (499) 704-16-49.

Drawing up estimates on the installation of a structured cable system (SCS) It refers to one of the most complex types of estimated calculations, when creating sufficient knowledge in the field of automation, means of communication and directly electrical work. The peculiarity of this type of calculation is that when installing the LAN, SCS and telecommunications systems, a variety of modern, imported materials, often not having analogues in the estimated base of rates, are applied. Thus, when drawing up a estimate for the installation of a structured cable system (SCS), it is necessary to make the installation of cross and patch panels, RJ sockets and accessories to cable boxes, as well as the UTP gasket coaxial and optical cables. The correct selection of rates for ridicuing current non-standard solutions to launch a local computer network and other low-current work and refers to the competence of a professional estimator, which should be aware of technical innovations and classical approaches in the SCS.

Sample estimates for low-current systems (low-voltage), as well as calculations on the device of a local computing network, may include rates of various types, but the most common option is the integrated use of several parts from the collection to install equipment, namely installation of electrical installations , automation and communication tools. Calculations on the installation of a structured cable system often include such electrical rates as the installation of plastic boxes (ter (GESN) M 08-02-390)) and cable channels, Laying the UTP cable in the box, the gasket of viniplast (corrugated) pipes with tightening In them, the main (GESN) M 08-02-409 and ter (GESN) M 08-02-412, the labeling of cable connections. In more detail about the use of rates for electrical work in the estimated calculations, it is possible to read in the material on the compilation of estimates for the electrical installation. In the same review, it is proposed to consider the options for setting up the installation of low-current cable systems using rates for automation and installation of communication equipment.

Basically the structure of the automation collection (part 11 of farms / GESNM / TERM) can be represented as a complex of eight departments made up from rates on the installation of various devices and equipment. This section opens with rates for installing structures for instruments and mechanisms. Other collection tables directly calculate the cost of installing automation tools that can be installed on equipment, mortgage devices: threaded and flange connections. The third and fourth departments include rates on measuring equipment and instruments operating in industrial premises, with installation on shields, consoles and metal structures, as well as equipment ASDU, Rent, AUTP, AIS, groove, incl. Consoles, scoreboard, screens, blocks. Section 2 Automation Collections Contains Rates on the cutting of shielded wires and cables and their inclusion in the plug connectors, and the section 8 - on connecting tube and electrical wiring to automation systems.

As an example of the use of rates from the assembly of assembly work in terms of automation, as well as electrical equipment and communications, take the local estimate for the installation of SCS, where the installation of the equipment, and the electrical appliances themselves are highlighted in two sections: installation work and materials.

Example of estimates for low-current work (structured cable systems)

In the example of the estimated calculation, the electromaterials and equipment are installed according to the rates, since they are taken from the price list of suppliers and may vary both by the price and electrical parameters. Some materials and equipment: Cable box 105x50 Legrand, corrugated pipe, Utro cable, cable metal organizer, connecting cord, sockets, RJ45 patch panel, accessories kit Legrand. Passive switching equipment and other network elements constituting the structural cable subsystem are taken at the estimates at the prices of suppliers minus VAT, taking into account TZP. This sample of estimates on the SCS is impractical to use in other calculations without making the necessary adjustments, since only an example or option of selecting rates for substantiates of low-current work is posted here.

Technical task: Creating a local network for 18 jobs in office space. The height of the ceilings is 2500mm. Wall material - brick, thickness up to 300mm. In the sided ceiling corridor, the distance from the suspended ceiling to the overlap of 100mm. Installation of sockets to exercise 300mm from the floor. Server and cross equipment installed.

Justification of the use of materials: The distance from the suspended ceiling to overlap 100mm does not allow the installation of metal trays, we carry out the cable laying in the PVC pipe (the requirements of GOST R 53246-2008 are forbidden to lay the cable directly on the panels or the carrier frame of the raw-holder). The cable is placed in Cable Channel 40x. 20, providing according to GOST 53246-2008 50% filling coefficient. The cable-channel gasket is carried out along the perimeter of the room due to significant rotation of jobs in office space, this solution will allow you to add new jobs in a short time. CableUTP 5 E. It is calculated based on the length of the cable channel, the vertical descent to the 2000mm communication socket and the reserve 3000mm in the telecommunications distribution cabinet according to GOST 53246-2008.

Performance of work on time and stated budget. Check Prices for SCS. We carry out the design and installation of the SCS network (LDC) in Moscow, Moscow region and the Central Federal District. System guarantee for installation of SCS (LAN) 25 years.

After performing design work on the SCS or receiving from the Customer, a ready-made project (the presence of a project in most cases, both for high-quality installation of SCS, and for the further operation of the system) is prepared a plan for the implementation and project of work on the installation of computer networks SCS, which strictly adheres to the assembly the Department. In cases of major repair and construction work, a set of contractors work at the same time at the same time. And coordination of work with related organizations is an important part of the work of the team "Flexis".

Cable secrets SCS

When installing the SCS networks in the office or industrial facilities, the SCS cable highways, as the most flexible, are adjusted for overall ventilation, heating and even electrical trails. Very often, all engineering communications are successfully placed on projects of contractors of different engineering systems in the undercont space of the corridor.

But in the process of installation, it turns out that in fact the number of engineering systems is large, and there are few places in the undercont space. And the competent installation of CCS cable trails between ventilation, air conditioning, electrician, automatics, subject to the required rules and norms, is an important factor in the quality of the mounted system and the quality indicator and the work experience of the SCS contractor.

Typical cable track solutions for most objects as follows:

• for the main subsystem of the SCS building (between server and floors, for example), an inter-storey channel is organized using a staircase tray;
• within one floor, the main SCS highway is built from a wire or perforated tray from the server cabinet, optimally lay as close as possible to the central axis of the object;
• from the tray to the socket, the cable is placed in a corrugated tube in the patient space and in the cavity of the walls (for the hidden installation sockets), or in the undercover space and then on the wall in the cable channel.

SCS workplaces

When installing the SCS (laying LAN) the largest work and materials fall on horizontal subsystem SCS. This is a point-to-point connection, each port of the patch panel to each port (outlet) in the workplace. Separate continuous cable. Without breaks, without twists / sucks / connections. All these mounting tricks easily detects testing SCS. And such a system cannot be certified and put for a warranty period of 25 years.

Depending on the architectural and design and design solutions, jobs are equipped with different types of sockets with different ways of mounting SCS sockets:

• the hidden installation of the Valena Legrand SCS is mounted in the hollow walls of drywall at an altitude of 20-25 cm from the floor);
• sCS sockets for MOSAIC LEGRAND boxes (usually installed on the capital walls at the height of the desktop of the desktop, or under the table, installing the box on the table itself);
• sCS sockets for external installation, not the most aesthetic, but perhaps the cheapest option;
• rutters and columns for open spaces.

There is no fundamental quality difference between types of sockets, and the choice is due to the practicality of the solution on a specific object and the wishes of the customer.

Quality SCS

In addition to such obvious characteristics as the quality of design solutions used by materials and equipment, the performance of the installation work, a high-quality structured cable system (SCS) highlights the ability to scale the system without new significant costs. The ability to work with applications and execute business tasks not only today, but also tomorrow.
