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

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

How to calculate an estimate for a fire alarm

Installing fire extinguishing 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 normative documents in the field of fire safety obliges commercial property owners to do this.

When drawing up an estimate 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 items:

1. carrying out preparatory work, including drafting;
2. cost of fire protection system;
3. installation, launch and commissioning of the system;
4. Maintenance.

Only specialized companies are hired to carry out this work.

Preparation and design

Work on installing fire safety equipment begins with the development of the project.

For these purposes, a representative of the selected company is invited to the site, who takes on the task of drawing up a draft version.

It takes into account the following:

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

Based on these data, a plan is prepared that depicts the future location of technical equipment, 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 preparation of the project 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 implementation commissioning works.

During installation fire alarm in the estimate for design work The cost of drawing up a layout of the main unit and additional devices is included. For a room of 35 m2 approximate cost the work will cost 2,300 rubles.

Features of equipment selection

The final estimate depends on the type of equipment selected.

Address. This type devices are installed in premises subject to increased safety requirements.

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

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

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

When drawing up an estimate for the commissioning of a 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 increased ambient temperature.

When these factors are detected, the system sends an alert to the security console and turns on sirens warning 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. thermal sensors– 46-80 rub.;
6. smoke detectors - 230-850 rubles;
7. KSPV cable – 3-5.50 rub./m;
8. fire-resistant cable KPSE – 150 rub./m;
9. main unit – from 2300 rub.

This is just a sample list of materials. domestic production.

Carrying out installation and commissioning work

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

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

The price includes construction and electrical installation work(drilling holes, punching walls, laying cables, installing and connecting sensors, etc.), as well as increasing coefficients. They are installed for work according to the customer’s schedule, for urgency, for performing installation work at height, etc.

Maintenance

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

Reluctance to carry out monthly maintenance threatens 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

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

It includes the cost of equipment and Supplies, labor costs, transportation costs and multiplying factors. This is the only way to avoid mistakes and unexpected financial costs.

Today there are quite a lot of ready-made estimate calculations available on the Internet, so downloading a local area program for the OPS is not at all difficult. All examples of estimates can be divided into several types of calculations:

- installation estimate security and fire alarm system ;

- // - setting up technical means;

Commissioning works at established fire protection facilities;

Repair and maintenance of existing equipment.

To draw up estimates for the installation of fire safety equipment, connection and connection of devices, use installation collections of territorial or general element standards in parts 8, 10 or 11 in accordance with 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 an estimate for electrical installation work, then you can read about the 10th and 11th parts, which contain most of the prices for installing a security and fire alarm system, in general provisions to these collections. Thus, 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, etc. In addition, usually, collections for electrical installations (electrical installations) take into account the costs of laying 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 on the installation of communication equipment is used to estimate the funds for the installation of devices, not including the costs of manufacturing and fastening incomplete structures to receiving and control devices, protecting blocking cables with surfaces with their color, the operation of the lifting mechanism when installing detectors and sensors on height. Commissioning works of security and fire alarm systems, consisting of object signaling devices and receiving control devices, taken into account under Part 2 for commissioning automated systems management.

According to the standards of Part 10 of the collections, the installation of:

Object, starting and signal receiving and control devices: base blocks on different quantity 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-electric devices with separately installed power supplies, converters or receivers, adjustable and fixed reflectors;

Designs for fire alarm devices.

Laying wires on wooden, metal, concrete foundations for security and fire alarm systems is carried out according to the prices of table 10-08-005.

Part 11 evaluates work on the installation of structures for instruments and actuators, table-top and floor-standing equipment, and devices installed on flange and threaded connections, boards, consoles, metal structures. For laying wiring in consoles and switchboards, the standards of department 6 are used, for connecting cables to devices - department 8 of the same collection.

As an 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, the laying of cable products and additional electrical installation work.

The presented example of an estimate for the installation of security and fire systems shows an algorithm for installing and configuring control and receiving devices with output to a cabinet-style control panel. Competent local estimates for an OPS, compiled on the basis of a project or specification, must be made according to current collections of territorial (TER, or FER / GESN) standards with adjustments for clarifying coefficients from the appendices and general parts of the current estimated pricing base.

Fire alarms are an integral part of any production facility. The issue of its installation should be approached as responsibly and seriously as possible. That is why only companies specializing in such work are involved in resolving such issues. Before you begin installation, you need to calculate the upcoming costs.

Payment procedure

Fire alarms are often installed in production premises. This is not popular in private houses and apartments. That is why correct design estimates should be given Special attention – financial calculations will be added to the general documentation, which will subsequently be checked by regulatory authorities. If we're talking about about a state budgetary enterprise, it is also important to explain the feasibility of the costs.

That is why state enterprises Most often, tenders are held in which several participating companies provide different variants estimates for installing a fire alarm. Next, according to various criteria, you select perfect option– the optimal ratio of the proposed quality and cost.

Before drawing up an estimate, an inspection of the object is carried out, its study and further drawing up of a diagram. Based on the resulting plan, financial calculations are already carried out.

Expenditure

Each estimate includes certain sections - they are standard, but in one case or another, some of them may be missing (if you need to calculate not the entire completion of the work, but only a certain stage). Next for each specific situation Detailed calculations are carried out for each section. In relation to the fire alarm estimate, the following main sections should also be taken into account:

1. Payment to workers. This item conditionally divided into 2 sub-items: direct installation of alarm systems (payment is calculated directly for the entire amount of work), and also construction works(further putty, finishing the walls where the cable will be laid). You can also additionally take into account the payment for drawing up the diagram if it is allocated as a separate section - sometimes this is included in the total cost of work on the facility. If digging trenches is required, it is possible to attract workers whose payment is calculated on an hourly basis.
2. Equipment rental. In fact, any special equipment in this case it will not be required for the work. The only exceptions can be those situations when it is necessary to lay the cable underground or outside along the wall on the upper floors of a multi-story building. Renting a car with a lift is often calculated on an hourly basis. But there is an important caveat to consider: sometimes the necessary equipment can be provided for rent. Many companies prefer to enter into such agreements with their clients, and then the cost of the equipment will also need to be indicated in this section of the estimate. The rest of the equipment that is usually necessary for installing an alarm system is already available from specialized companies.
3. Materials. If you need to purchase equipment, then it is indicated in this section and then placed on the balance sheet of the enterprise. This section should also provide auxiliary materials(mounting for equipment, wires, sensors). The second subsection is to calculate the costs of Finishing work, which will follow after the installation of the system is completed (paint, putty, wallpaper). If Construction Materials If you do not purchase them right away, their prices may rise in the future, which you must warn the customer about.

If we are talking specifically about the installation of a fire alarm, then it would be logical to highlight the costs of commissioning work as additional items. Sometimes they can be divided between previous sections(purchase of software and payment of employees), then it is much more convenient to highlight this in a separate column.

Distinctive feature fire alarm system is that in the future it will be necessary to pay for its maintenance (monthly fee). This amount is not included in the initial estimate for its installation at all. Even the payment for the first month is not reflected anywhere - these are completely different expense items that will need to be taken into account in the future when filling out financial documentation. This estimate only takes into account the costs of installation itself.

Types

Depending on what type of fire alarm is chosen by the customer, the final estimate will also differ. Many experts advise to first calculate and evaluate each of the options, and only then choose the optimal one.

1. Address. This type of alarm is very convenient because it allows not only to record information about the occurrence of a fire, but also to determine its clear location. For this reason, the danger can be neutralized much faster, since there is no need to waste time searching for the source of the fire. All information is transmitted to the remote control, and each sensor is assigned a clear address. In the estimate, the main difference will be the higher cost of commissioning work (it costs more to set up such a system), as well as the somewhat more expensive sensors themselves.
2. Automatic. Not only sends a message to the security post, but also displays an emergency evacuation message. Installation costs are reflected in the estimate as standard, but the equipment will cost more.
3. Autonomous. The most budget-friendly. But it does not allow us to determine the location of the fire. Sensors and program setup costs will be cheaper.

Design

It is usually customary to allocate the drawing up of a diagram as a separate cost item if this is done by another company, and not directly by the contractor who will install the alarm.

Most often, it is those companies that will subsequently install fire alarms that draw up the scheme. This preliminary work included in the price of the object. If this is not provided for or for some reason the scheme will be prepared by another company (subcontractor), then it is allocated as a separate expense item.

Sometimes this task can be delegated to state regulatory authorities so that in the future there will be no problems with the acceptance of the object. Then the layout of the sensors and the central console is prepared by a government organization based on all standards. And then, according to this scheme, the contractor will install the alarm itself.

The diagram is an integral component in this work, since without it it will not be possible to estimate the upcoming costs - already on the basis of this plan the cost of the necessary materials will be calculated.

Sensors and the remote control cannot be arranged in a chaotic manner or in a standard manner for any room - their number and location are determined separately for each type of object. Initially, the object is analyzed, and then, taking into account its type and specific activity, a diagram is formed. In this case, the standards approved for this type of premises are taken into account (for a residential apartment and a workshop they will be completely different).

If the contractor is directly involved in drawing up the diagram, then it is necessary to approve the drawn up project - this will help to be on the safe side and prevent the identification of any inaccuracies, which in the future will entail the need to redo the alarm.

Commissioning works

This type work implies inclusion in the estimate only the costs of paying specialists. They will have to set up software, establish synchronization. The estimate takes into account full payment for all work.

If during the test work any shortcomings are identified, then an additional estimate can be drawn up with a detailed calculation of the costs necessary to set up normal operation.

Sometimes you may need to install additional programs to ensure normal operation. If these programs are paid, then their cost will also be taken into account in the overall calculation.

Dismantling

In some cases, partial or complete removal of the fire alarm may be required. Partial dismantling required if a person is forced to change the company providing the alarm service. In this case, it is necessary to include the purchase in the estimate necessary equipment(sensors, remote controls) and payment for commissioning works.

If for some reason a complete dismantling of the system is required fire alarm, then it is necessary to include further finishing work in the estimate. In addition to removing the sensors and dismantling the wires, it is also necessary to seal the resulting gaps.

In this case, the estimate takes into account the costs of paying builders, purchasing finishing materials(putty, paint, wallpaper). Workers' compensation is calculated in full for the entire facility. You also need to take into account the cost of renting transport for removal. construction waste– usually equipment is paid for 1 trip per trip or hourly.

Important point! With the complete dismantling of the alarm system, in addition to expenses, income can also be taken into account in the final estimate. The removed equipment can sometimes be handed over to a company providing such services for a fee, or simply sold. Then this amount can partially compensate for upcoming expenses.

One of important issues, which property owners ask themselves when planning to install an alarm system, will be question about cost. Estimates for fire and security alarms (FS) are being developed contractor and is presented to the customer for approval before the start of work. Some items in the estimate may be adjusted.

Preparatory work for OPS

It all starts with the preparation of working documents. To do this, a representative of the security organization visits the site to draw up a preliminary design.

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

• Number of premises
• Number of doors, windows and other access points (hatches, ventilation shafts and etc.)
• Ceiling height
• Presence of possible “dead” zones
• Other characteristics

Based on these data, a required documentation, which includes the site plan and technical task for installers. All are shown on the plan technical means, including sensors, main unit, warning and indication means, cable routes, connection points for power supply and external devices.

The estimate for a security alarm includes the following items:

• Project preparation and documentation
• Cost of all components
• Programming the basic device
• Carrying out commissioning works systems

The cheapest way to install an alarm system is with security sensors in a standard apartment.

Almost 90% of all residential apartments carried out according to standard projects , and therefore drawing up a separate installation plan is not required.

Specialized installation organizations are used ready-made diagrams alarms for apartments with different numbers of rooms. At drawing up a project for a non-standard object the calculation is made based on the area of ​​the premises, and ranges from 60 to 200 rubles per square meter.

Based on this, the minimum cost technical project for an object with an area of ​​50 m2 will cost the customer approximately 3,000 rubles.

What increases the cost of installation work

If it is assumed, then the client of the security organization is entitled to various discounts. You should know that the cost of the project depends on the number of floors. So the cost two-level apartment area 150 m2 will be higher than the cost ordinary apartment the same area. Increasing coefficients also exist for ceilings over 3.5 meters and over 5.0 meters, for work carried out in the evening and at night and for work on days that are considered non-working.

Individual 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 in 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

Performance electrical installation 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, includes the cost of equipment and consumables, which include cables and various types of fasteners.

Approximate cost of individual technical equipment of alarm systems:

• Magnetic contact sensors (magnet-reed switch pair) 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
• Sensors that react to glass breaking - from 380 to 690 rubles
• Fire thermal 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 appliances, depending on the model – from 2,300 rubles

Domestic-made devices and cables are listed. Products from foreign branded manufacturers can cost much more.

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 equipment at a discount and it 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.

Cost of electrical installation work

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

Cost of some construction works:

• Drilling one hole – 10-20 rubles
• Passing a through channel in a wall up to 10 cm with a drill with a diameter of 20 mm – 100 rubles
• Drilling a through channel in a 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 channel - from 50 rubles

Electric installation work:

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

Examples of estimates for security alarms studio apartment, area 35 m2.

• 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 panel"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 a stand-alone security alarm system small apartment, can cost about 8,000 rubles. Prices are approximate, but the order allows you to draw certain conclusions, and.
