Quite a lot of ready-made estimate calculations are posted on the Internet today, so it's not difficult to download a LAN to the OPS. All examples of estimates can be divided into several types of calculations:

- estimate for the installation of security fire alarm ;

- // - setting up technical means;

Commissioning works at the installed OPS facilities;

Repair and maintenance of existing equipment.

To draw up estimates for the installation of security and fire equipment, connection and connection of devices, use assembly collections of territorial or general elementary standards in part 8, 10 or 11 according to the existing specification or project for the fire alarm system. If the structure of Section 8 is described in sufficient detail in the example of the estimate for the production of electrical work, then the 10th and 11th parts, containing most of the prices for the installation of security and fire alarms, can be read in the general provisions for these collections. So, the standards for the installation of communication equipment take into account the costs of setting up, adjusting and installing antennas, feeder devices, painting auxiliary structures and so on. In addition, usually, according to the collections for electrical installation (electrical installations), the costs of installation are taken into account cable products, grounding, as well as material resources indicated in the appendices to the sections. At the same time, non-standardized resources are averaged in the list of resources at around 2% of workers' wages. Section 8 of the collection for the installation of communication equipment is used to assess funds for the installation of devices, not including the costs of manufacturing and fastening incomplete structures to receiving and control devices, protection of interlocking cables with surfaces with their paint, the operation of the lifting mechanism when installing detectors and sensors on height. Commissioning of the security and fire alarm system, consisting of object signaling devices and receiving and control devices, are taken into account in part 2 for the commissioning of automated control systems.

According to the standards of part 10 of the collections for construction and installation work, the installation can be observed:

Object, starting and signal receiving and control devices: base units for a different number of beams, intermediate devices;

Automatic fire alarm detectors: electrical and magnetic contact, thermal, photoelectric, smoke, light;

Detectors burglar alarm: magnetic and shock-contact window or door, electromagnetic;

Object signaling devices: capacitive, ultrasonic, photo- and optical-electrical devices with separately installed power supplies, transducers or receivers, adjustable and fixed reflectors;

Designs for OPS devices.

Laying of wires on wooden, metal, concrete bases for security and fire alarm systems is carried out at the prices of Table 10-08-005.

Part 11 deals with the installation of structures for instruments and actuators, table and floor equipment, and devices installed on flange and threaded connections, panels, consoles, metal structures. For wiring in consoles and panels, the standards of department 6 are used, for connecting cables to devices - department 8 of the same collection.

For example, we will draw up an estimate for the installation of a security and fire alarm system with the connection of a set of detectors, a remote control, auxiliary devices, laying of cable products and additional work on electrical installation.

Sample estimate for FSA (connection of security and fire alarm devices).

The presented example of the estimate for the device of security and fire systems shows the algorithm for the installation and adjustment of control and receiving devices with output to the cabinet-type control panel. A competent local estimate for the OPS, drawn up on the basis of a project or specification, should be made according to the current collections of territorial (TEP, or FER / GESN) standards, adjusted for clarifying coefficients from the annexes and common parts of the current estimated pricing base.

Often, an alarm system is installed to protect their property. They can alert the security guard about the entry into the facility. The burglar alarm contains a device that, with the correct analysis of the received information, signals a violation. In addition, the system includes a control panel, sensors and other auxiliary devices. The security system requires careful design and compliance with all established standards.

Design

An example of a burglar alarm project (FSA)

It is better to create a project even at the stage of construction or renovation, since work can disrupt Finishing work and lead to additional financial costs. The burglar alarm design takes into account the type, layout of the building and regulations.

Security alarm design takes place in three stages. At the initial stage, several sketch sketches are made. Here they take into account all the set technical tasks, a full study of the documentation that is available for the future protected object is underway, and all the recommendations of the experts are taken into account.

The preliminary design is the most important as it contains the final location of the security devices. In addition, the budget is calculated here and the tasks of the future security system are determined. An example of a draft design will be supplemented with an explanatory note, which deciphers the entire installation, its advantages or disadvantages.

After drawing up several sketches, where there may be significant differences in the degree of protection and its management, the customer will choose the option that suits him best. Changes in the course of the negotiations are not ruled out either.

Having decided on the project, they proceed to the second stage of design. It is already of a technical nature, where the installation of the security system is determined in accordance with the structure. Here routes for laying networks are selected, software is selected and issues with power supply are resolved. The example will also be provided with an explanatory note, drawings and technical documentation. The technical project already gives the right to carry out the installation.

The design of the security alarm system must comply with all established and approved standards listed in the Electrical Installation Rules (PUE), GOST and SNiP. Special organizations in the design and installation always take into account the necessary requirements. The same thing happens when making an estimate. , as installation may change significantly during regulatory validation.

Budgeting

An example of an estimate for the installation of a security alarm in the "Grant estimate" program

The estimate always includes three groups: material, services, overheads. In addition, it is drawn up according to the principle of a complete listing of the prices of goods and works for the installation of security alarms.

Main characteristics of positions:

• Name;
• unit;
• number;
• the cost of one unit of goods or work;
• total amount.

Before accepting and signing the acceptance certificate, you should carefully check the strict compliance of the specified works and the name of the goods. Here you need to double-check the name of the product and its model, which will be indicated in the estimate and upon installation. Quite often, the estimate includes additional items that must be carefully checked.

Special computer programs are used to make estimates. Usually, each firm works according to a program convenient for it, and also use those that are intended for their type of activity. The most popular programs include Grant Estimate, Estimate, My Estimate, Mini-Estimate, Kors Estimate, etc. Some large firms use their own development of estimate files in Excel format or programs, which contain the company's standards and the approved estimated price for material and work.

Estimated cost of installation

A certain coefficient will be used in the calculations. It directly depends on the number of security lines. For two lines, a coefficient of 1.2 is used, for three lines - 1.3. Often a building consists of several rooms, where different modes of operation are applied, therefore, a factor of 1.1 is used in the calculations.

Often, the installation of a guarded alarm is carried out along with the installation of video surveillance. Then, when making an estimate, the cost is summed up, that is, the services for the installation of burglar alarms and video surveillance are calculated separately. The installation of a security and fire alarm system is considered using an underestimated coefficient - 0.8.

Not a single enterprise can do without a security alarm. This is an important aspect in the work of an organization.

Most burglar alarms are quite complex engineering systems. For installation in an enterprise or organization, as a rule, separate projects are developed that take into account many criteria of the object. Starting from the plan of the interior and the distribution of power supply networks and ending with decorative suspended ceilings.

A security alarm estimate is one of the most important design documents. According to it, the customer will have information about the cost and range of equipment used, the cost of installation work, their duration, sequence.

Features of drawing up

Design work and budgeting should be carried out by the organization that will install the burglar alarm. Using a project developed by other firms is not advisable. There are several objective reasons why the use of "someone else's" estimates is inappropriate:

• The cost of installation and component parts can differ significantly, usually upward. This is due to the fact that each company has its own pricing policy, suppliers. In addition, the prices of detectors and controllers in different regions Russia is significantly different;
• Price coefficients associated with the location of the object, its area, distance from the main base of building materials and devices are individual for each company;
• In most cases, such estimates, as part of the design work, are made free of charge as a bonus from the contractor company.

It is highly recommended that you make a quote with a professional design engineer specializing in security systems. Since there are many nuances that an ordinary engineer may simply not know about. As a result, the cost may differ significantly from that laid down in the document, both upward and downward.

Description of the main items

1. Outwardly, the estimate is a table in which the following information must be present:
2. The name of the product used in the work or the work process itself;
3. The unit in which the work or product is measured (pieces, running meters connected devices);
4. Number of products or work processes;
5. The cost of one unit of a product or work performed;
6. The total amount for each item, which is added to the total total of the entire estimate of both the products used for the security alarm system, and all the work performed on their installation.

The estimate must contain the exact designation of the products used. Specific models and their short description... For example, the glass-break sensor "Glass - 3". Also, specific types of work should include the exact number of cycles. For example, laying an information cable network in the director's office 37m, connecting smoke sensors 4 pcs.

Therefore, a correctly drawn up estimate will have three main sections:

1. Materials and products used;
2. Performed work (services);
3. Overheads.

It is allowed to include in the estimate such non-obvious costs as equipment depreciation, the coefficient of territorial costs (if the object is far from the contractor's company).

Among other things, the estimate signed by the contractor's organization is evidence in court in the event of unfairly fulfilled obligations.

All public, industrial and administrative buildings must be equipped with fire protection systems.

This equipment will help to timely detect the source of fire, save lives and preserve the integrity of property.

How to calculate an estimate for a fire alarm

The installation of fire-fighting devices will minimize the likelihood of a fire, and in some cases prevent a fire.

And although they are rarely installed in private houses and apartments, the current regulatory documentation in the field of fire safety obliges owners of commercial real estate to do this.

When drawing up a budget for a fire alarm, it is necessary to take into account many nuances, which will help to avoid problems with regulatory authorities.

The costs include several main points:

1. holding preparatory work, including the preparation of the project;
2. the cost of the fire protection system;
3. installation, start-up and commissioning of the system;
4. Maintenance.

Only specialized companies are involved in this work.

Preparation and design

Firefighting equipment installation work begins with the development of the project.

For these purposes, a representative of the selected company is invited to the object, who undertakes to draw up a draft version.

It takes into account the following:

• the number of premises in the production building;
• number of windows, doors, hatches, ventilation shafts and other access points;
• ceiling height;
• other characteristics of the object.

Based on this data, a plan is prepared, which depicts the future location of technical means, including the main unit, sensors, warning devices, etc.

If you look at an example of an estimate for a fire alarm, you can see that the design is taken into account as a separate cost item.

But only if an organization is involved in the design that will not take part in the installation and commissioning.

When installing a fire alarm, the cost of drawing up a layout for the main unit and additional devices is included in the estimate for design work. For a room with an area of ​​35 m 2, the approximate cost of the work will be 2300 rubles.

Features of the choice of equipment

The result of the final estimate depends on the type of equipment selected.

Addressable. This type of device is installed in rooms with increased safety requirements.

When they are installed, an address is assigned to each room in the building. In the event of a fire, the equipment detects the source of the fire, establishing the address of its location.

For example, when installing equipment based on the Bolid, the estimate for the fire alarm will include significant costs for commissioning. This is due to the complexity of the system configuration.

Automatic. This is a complex device that detects the source of fire and transmits data about it to the remote control. Most of the APS models are associated with automatic fire extinguishing systems.

When budgeting for the commissioning of the fire alarm, the costs will remain standard. And the equipment itself will cost much more.

Autonomous. This system is connected to the security console.

And its main purpose is to detect smoke and increase in ambient temperature.

When these factors are detected, the system sends an alert to the security console and turns on the sirens to warn of danger.

A sample estimate for a fire alarm would look like this:

1. magnetic contact sensors for opening - 30-180 rubles;
2. IR motion sensors - 370-450 rubles;
3. radio wave motion sensors - 870-1200 rubles;
4. sensors installed on glass - 380-690 rubles;
5. heat sensors - 46-80 rubles;
6. smoke detectors - 230-850 rubles;
7. cable KSPV - 3-5.50 rubles / m;
8. fire-resistant cable KPSE - 150 rubles / m;
9. main unit - from 2300 rubles.

Here is only an approximate list of domestically produced materials.

Installation and commissioning works

Installation of equipment, its start-up and commissioning are most often carried out by the forces of the same company. If you look at a sample estimate for a fire alarm, this item includes the remuneration of specialists. They also configure the software and synchronize the devices associated with it.

If, in the process of checking the operability of the fire alarm, shortcomings are revealed and unplanned work is required, an additional estimate is drawn up.

The price includes construction and electrical assembly work(drilling holes, chipping walls, laying cables, mounting and connecting sensors, etc.), as well as increasing factors. They are installed for work according to the customer's schedule, for urgency, for performing installation work at a height, etc.

Maintenance

The need for maintenance is regulated by the Fire Fighting Regulations. Fire alarm maintenance is included in the estimate as a separate expense item.

Failure to do monthly maintenance threatens with false alarms of the security system and problems with competent services.

The cost of this event depends on the area of ​​the facility where the fire safety system is installed.

Conclusion

Registration of expenditure documentation should begin by drawing up an example of an estimate for a fire alarm.

It includes the cost of equipment and consumables, labor costs for workers, transportation costs and multipliers. This is the only way to avoid mistakes and unforeseen financial costs.

One of the important questions that property owners ask when planning the installation of an alarm will be cost question... The estimate for the security and fire alarm (FSA) is developed by the contractor and submitted to the customer, for approval, before the start of work. Some items of the estimate can be adjusted.

Preparatory work on the OPS

It all starts with the preparation of working papers. For this, the object is visited by a representative of a security organization to draw up a draft design.

The project takes into account the following characteristics of the object:

• Number of rooms
• The number of doors, windows and other access points (hatches, ventilation shafts, etc.)
• Ceiling height
• The presence of possible "dead" zones
• Other characteristics

Based on this data, required documentation, which includes the site plan and terms of reference for installers. The plan shows all technical means, including sensors, the main unit, notification and indication means, cable routes, power supply and external devices connection points.

The estimate for the security alarm includes the following items:

• Project preparation and preparation of documentation
• The cost of all components
• Basic device programming
• System commissioning

Installation of an alarm system with security sensors in a standard apartment will be the cheapest.

Almost 90% of all apartments in the housing stock executed according to standard projects, and therefore a separate assembly plan is not required.

Specialized installers use ready-made alarm schemes for apartments with different numbers of rooms. At drawing up a project for a non-standard object the calculation is based on the area of ​​\ u200b \ u200bthe premises, and ranges from 60 to 200 rubles per square meter.

Based on this, the minimum cost of a technical project for an object with an area of ​​50 m 2 will cost the customer about 3,000 rubles.

Which increases the cost of installation work

If it is assumed, then the client of the security organization is entitled to various discounts. You should be aware that the cost of the project depends on the number of floors. So the cost of a two-level apartment with an area of ​​150 m 2 will be higher than the cost an ordinary apartment the same area. Increasing coefficients also exist for ceilings over 3.5 meters and over 5.0 meters, for work in the evening and at night and for work on days that are considered non-working.

Separate coefficients that increase the cost of work:

• Urgency coefficient - 1.2-1.3
• Work according to the customer's schedule (morning and evening hours) - 1.4
• Night work - 2.0
• Work on holidays - 2.0
• Installation work at a height above 3.5 meters - 1.5
• Installation work at a height above 5.0 meters - 2.0

Performing electrical work in a hidden way increases the total cost by 10%, and the use of technical means from foreign manufacturers increases the cost by at least 30%.

Equipment costs - example estimate

Main expense item when installing any type of alarm, it includes the cost of equipment and consumables, which includes cables and fasteners of various types.

The approximate cost of individual technical means of alarm systems:

• Magnetic contact sensors (a pair of magnet-reed switch) for opening - from 30 to 180 rubles
• Infrared motion sensors - from 370 to 450 rubles
• Radio wave motion sensors - from 870 to 1,200 rubles
• Glass break sensors - from 380 to 690 rubles
• Fire heat sensors - from 46 to 80 rubles
• Smoke fire detectors DIP - from 230 to 850 rubles
• Cable KSPV 2 X 0.5 mm - 3 rubles per meter
• Cable KSPV 4 X 0.5 mm - 5.50 rubles per meter
• Fire-resistant cable KPSE "ng" 2 X 0.5 mm - 15 rubles per meter
• Basic devices, depending on the model - from 2,300 rubles

Domestic devices and cables are listed. Products from foreign brand manufacturers can be much more expensive.

Many, trying to save money, purchase sensors and other devices on their own. This is not recommended for a number of reasons. Firstly, security organizations purchase technical means at a discount and they will also cost the customer less. Secondly, everything that is offered by the security structure, tested and certified, and if you buy it yourself, you can buy a defective product.

The cost of electrical work

The cost of construction and installation work, for different companies, may differ significantly, therefore, before concluding a contract, it makes sense to get acquainted with the prices and warranty obligations of various companies and only after that make your choice.

The cost of some construction work:

• Drilling one hole - 10-20 rubles
• Passage of a through channel in the wall up to 10 cm with a drill with a diameter of 20 mm - 100 rubles
• Passage of the through channel in the wall from 10 to 50 cm with a drill with a diameter of 20 mm - 500 rubles
• Wall chipping, depending on the material - 200-400 rubles
• Laying one meter of cable duct - from 50 rubles

Electric installation work:

• Laying one meter of cable open way- from 20 rubles
• Laying one meter of cable in the channel - from 15 rubles
• Installation and connection of the sensor - from 200 to 350 rubles
• Installation, connection and setup of the main unit - from 2,300 to 3,500 rubles

Examples of estimates for burglar alarms studio apartment, with an area of ​​35 m 2.

• Project and wiring diagram - 2 100 rubles
• Magnetic contact sensors on front door and two windows - 690 rubles
• Three IR volumetric sensors (cost and installation) - 1710 rubles
• Single-loop control device "Quartz" - 2 250 rubles
• Siren - 350 rubles

To the amount of 7,100 rubles, you need to add the cost of the cable and fasteners. Thus, the cost of an autonomous security alarm in a small apartment can cost about 8,000 rubles. Prices are approximate, but the order allows you to draw certain conclusions, and.
