Often, to protect their property, they install a system burglar alarm. They can notify the security guard about intrusion into the facility. A security alarm system contains a device that, when correctly analyzing the information received, signals a violation. In addition, the system includes a control panel, sensors and other auxiliary devices. A security system requires careful design and compliance with all established standards.
Design
Example of a security alarm project (SSA)
It is better to create a project at the construction or renovation stage, since the work may disrupt Finishing work and lead to additional financial costs. The security alarm design takes into account the type, layout of the building and regulations.
The design of a security alarm takes place in three stages. At the initial stage, several sketches are made. Here, all the assigned technical tasks are taken into account, the documentation that is available for the future protected object is fully studied, and all recommendations of experts are also taken into account.
The preliminary design is the most important because it contains the final location of the security devices. In addition, the budget is calculated here and the tasks of the future are determined. security system. Example preliminary design will be supplemented explanatory note, where the entire installation, its advantages or disadvantages are deciphered.
After drawing up several sketches, where there may be significant differences in the degree of protection and its management, the customer will choose the most suitable option. Changes during the negotiations are not excluded.
Having decided on the project, they move on 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 and resolve issues with power supply. The example will also be provided with an explanatory note, drawings and technical documentation. The technical design already gives the right to carry out installation.
The design of a security alarm system must comply with all established and approved standards listed in the Electrical Installation Rules (PUE), GOST and SNiP. When designing and installing, special organizations always take into account necessary requirements. The same thing happens when budgeting, as installation may change significantly during regulatory approval.
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, overhead. In addition, it is compiled on the principle of a complete listing of prices for goods and work for the installation of a security alarm system.
Main characteristics of positions:
- Name;
- unit of measurement;
- quantity;
- 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 work and the name of the product. Here you need to double-check the name of the product and its model, which will be indicated in the estimate and upon installation. Often the estimate includes additional items that must be carefully checked.
To prepare estimates, use special computer programs. Typically, each company works according to a program that is convenient for it, and also uses those that are designed for their type of activity. The most popular programs include “Grant Estimate”, “Estimate”, “My Estimate”, “Mini-Estimate”, “Kors Estimate”, etc. Some large companies use their own development of estimate files in Excel format or programs that contain company standards and approved estimated prices for materials and work.
Approximate cost of installation
A certain coefficient will be used in 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 operating modes are used, so a coefficient of 1.1 is used in calculations.
Often the installation of a protected alarm system is carried out together with the installation of video surveillance. Then, when drawing up an estimate, the cost is summed up, that is, the services for installing a security alarm and video surveillance are calculated separately. Installation of security fire alarm is calculated using an underestimated coefficient of 0.8.
No business can operate without a security alarm. This is important aspect in the work of the organization.
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. The plan shows all technical means, including sensors, the 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
Performing electro installation work in a hidden way increases the total cost by 10%, and the use 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 system, includes the cost of equipment and Supplies, which includes 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
- Firefighters 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
Devices and cable are listed domestic production. 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 receiving and 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 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.
Most security alarms are quite complex engineering systems. For installation at an enterprise or organization, as a rule, separate projects are developed that take into account many object criteria. Starting from the plan interior spaces and wiring of power supply networks and ending with decorative suspended ceilings.
The security alarm estimate is one of the most important documents in the design process. According to it, the customer will have information about the cost and range of equipment used, the cost of installation work, their duration, and sequence.
Features of compilation
Design work and budgeting should be carried out by the organization that will install the security alarm. Using a project developed by other companies is not advisable. There are several objective reasons why using “someone else’s” estimates is inappropriate:
- The cost of installation and components can vary significantly, usually upward. This is due to the fact that each company has its own pricing policy and suppliers. In addition, prices for detectors and controllers in different regions Russia is significantly different;
- Price coefficients associated with the location of the facility, its area, distance from the main base of building materials and devices are individual for each company;
- In most cases, such estimates as part design work, are produced free of charge as a bonus from the contractor company.
It is strongly recommended that you prepare an estimate in conjunction with a professional design engineer who specializes 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 stated in the document, both upward and downward.
Description of main positions
- Externally, the estimate is a table that must contain the following information:
- The name of the product used in the work or the work process itself;
- The unit in which work or goods are measured (pieces, linear meters, connected devices);
- Number of products or work processes;
- The cost of one unit of product or work performed;
- The total amount for each item, which is included in the total total amount of the entire estimate for both the products used for the security alarm system and all work performed on their installation.
The estimate must contain the exact designations of the products used. Specific models and their short description. For example, the glass break sensor “Glass - 3”. Also specific types works should include exact amount cycles. For example, laying information cable network in the director's office 37m, connection of smoke sensors 4 pcs.
Therefore, a correctly drawn up estimate will have three main sections:
- Materials and products used;
- Works (services) performed;
- Overheads.
It is allowed to include in the estimate such non-obvious costs as wear and tear of equipment, territorial cost coefficient (if the facility is located 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 obligations fulfilled in bad faith.
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 operating 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, 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;
Security alarm detectors: 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 fire and security 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.
