How to install a fire alarm. Installation of fire alarm systems

System fire alarm is a necessary condition for the construction of some objects. First of all, this applies to buildings where explosive substances are stored. This includes buildings in the healthcare, general education, and manufacturing industries.

The safety of any premises depends on the correct installation of fire alarms. Incorrectly performed installation work will not only not protect the structure during a fire, but will also contribute to the issuance of fines.

Alarm device

The main function of a fire alarm system is to detect a fire in a room using installed systems sensors Modern manufacturers suggest using the following sensors in fire alarm systems:

• optical;
• smoke;
• thermal.

Optical sensors are capable of detecting infrared or ultraviolet radiation that is released during the combustion process. Smoke detectors respond to increased smoke levels, and thermal detectors respond to a sharp increase in temperature. Often, for system reliability, devices of different types are combined.

All sensors can be divided into wired and wireless. All of them are connected to a central console, which receives the corresponding signals from the sensors. After processing the information, the location of the fire is determined, a control signal is turned on, which starts the warning and fire extinguishing system.

This system is quite complex, so installation of a fire alarm can be carried out if there are design documentation that takes into account the purpose of the facility.

Design, connection and maintenance of alarm systems are permitted only to those companies that have certificates and licenses to carry out this work.

When preparing design documentation, they develop technical task. It is subsequently used to make a layout of cables and devices.

Installation norms and rules

The list of all norms and rules that describe installation features is quite large. But the main ones should be mentioned.

Acquainted with full list rules you can in GOST and SNIP. In addition, you should pay attention to Federal laws, on which the design documentation is based. It is also necessary to comply with the requirements of Fire Safety Standards.

If the installation requirements are not met, it is necessary to dismantle the installed equipment and carry out all work in accordance with the standards. In this case, dismantling will be carried out at the expense of the performing company.

The installation of a fire alarm must be carried out taking into account all the requirements:

• fully comply with the design documentation and the specifics of the premises;
• high-quality performance of work.

In a protected building, it is advisable to divide all the premises into several control zones, in each of which a certain number of sensors are installed.

Electrical network standards

Power and communications networks are also receiving special attention. After all, they must be resistant to fire. As the room temperature rises, their insulation must be maintained.

Communication and power wiring must be laid in different channels. Where they intersect with the electric main, they must be equipped with additional reliable insulation.

The central control panel must be located in a specific room. Access to it should be limited to maintenance personnel. There are several types of control panels. Each of them can be used in certain conditions. Accordingly, the assembly of each device is individual.

When choosing, choose a conductor with a larger cross-section than for lighting fixtures.

Installation

Current legislation does not prohibit installing fire alarm systems yourself. All work must be carried out in accordance with certain rules that are prescribed in the project documentation.

But experts recommend that the system be installed by professionals. On your own, with the skills to work with such systems, you can assemble a system for your home. Complex designs should only be carried out by specialists who guarantee the serviceability of the structure as a whole.

Specialists connect the sensors in accordance with previously prepared diagrams and instructions for the devices.

An example of installing a foam or water fire extinguishing device. They are used in libraries, shops, hospitals, hotels, etc. The water flow in such a system must be at least 10 l/s. In case of fire, the water supply should be at least 30 minutes, and the distance between sprinklers should be no more than 4 m.

The installation of a fire alarm should be carried out at a temperature of about +200, humidity of about 60%, in the presence of supply and exhaust ventilation.

After installation of the structure, it is necessary to carry out inspection work.

The cost of installing an alarm directly depends on the area of ​​the protected premises, and, accordingly, the amount of equipment used.

End of work

After the installation of the fire alarm system by the performing company and the customer, it is necessary to draw up a summary executive documentation. It is necessary to prepare the following documents:

• journal and executive diagrams;
• certificates of statements and tests, examination of hidden work;
• quality certificates of the materials used, their certificates;
• working drawings.

A complete list of all necessary documents can be found on the website of the Ministry of Emergency Situations.

How to disable the fire alarm system

Well, the connection is made in accordance with all the rules. The work order was followed. But during operation, the fire system may be triggered for no reason. At this time, you need to make sure that there is no fire, after which the device must be turned off. We figured out how to connect the systems, but how to turn them off? After all, an unpleasant specific sound is often produced. To turn off the alarm you must:

1. determine the reason why the alarm went off. Maybe for some reason there was an accumulation of smoke in the house or a small fire broke out. In this case, the room must be well ventilated;
2. If no reason is observed, then you need to turn off the device. A simple alarm can be easily turned off by turning off the power source from the sensors. The difficult one involves turning off the system from rooms with a central control panel. In this case, you will need to enter a certain code;
3. A radical method of eliminating unpleasant sound is to cut the wires. But remember, to restore the functionality of this alarm, in this case it will be necessary to carry out a number of sequential works.

Fire alarm installation: how we work

Fire alarm installation: stages of work

When the design work is completed, we can assume that an automatic fire alarm system already exists, albeit only in theory for now. All technical decisions have already been made, the type of alarm system has been selected, necessary equipment and materials selected. This system is unique and it will not fit any other object. Next stage- installation work that will put the plan into practice and “breathe life” into the very important system human protection.

That's why, installation of fire alarm systems- not only expensive, but also the most critical stage of work. It requires attention and control not only from the contractor, but also from the owner of the facility.

Any construction and installation work can be divided into two components:

1. Direct execution of work;
2. Preparation of acceptance documentation.

It cannot be said that one is more important than the other. Both components are needed for further stable operation of the system and its operation. Before handing over the completed work, the customer must have a fully tested and functioning fire alarm system and several folders with documentation.

As in the case of design, it would be nice for the customer to have in his arsenal a person who is able to understand all this and control the process. Large companies have no problem with this. An engineer is appointed by order, or even an entire engineering organization is contracted to carry out technical supervision over the work and documentation. If this is a one-time job for the customer, or there is simply no way to hire someone additionally, then you will have to figure out the key points yourself.

So where does the installation of a fire alarm begin?

Execution Process installation work can be divided into several stages:

1. Selecting a contracting company;
2. Inspection of the object and conclusion of the contract;
3. Purchase of equipment and materials;
4. Carrying out electrical installation work;
5. Carrying out commissioning work.

Fire alarm installation: choosing a contractor

When performing installation work, the most important thing for the customer is preparation. Find a company that will meet all the requirements, discuss all the subtleties and features of the object - this must be done before signing an agreement or contract. During the execution of work, it will only be possible to monitor compliance with all contractual obligations without interfering in the production process.

The choice among companies that install fire alarms is quite wide. Even in a relatively small city you can find a couple of such organizations. In order for the company to carry out this type activity, it must at least have a license from the Ministry of Emergency Situations of the Russian Federation.
Recently, specialized organizations have joined the ranks of members Self-regulatory organizations(SRO) and receive a “Certificate of Admission to Certain Types of Work.” In this certificate they are interested in the section “Installation of means fire protection" This certificate gives the right to carry out work on installing fire alarms in strict accordance with certain cases. Therefore, if you need to install an alarm in any “standard” operating building (shop, office, hotel), then having such a certificate is not necessary. But, if the company you choose has it, then this fact can definitely be considered an advantage.

Site inspection and conclusion of a contract for the installation of a fire alarm

Now a little about what is required from the customer before concluding a contract for installation work.

Firstly, you should have a project at stage “P” in your hands (or on electronic media). Based on this project, the installation organization will be able to calculate the price of the equipment, as well as the cost of construction, installation and commissioning work. If you have a project in in electronic format, then you can simply call several companies, send them the project by email and ask them to make a commercial offer. In this case, you will not have to waste time on meetings or travel. And the proposals received can be compared in terms of cost and other conditions (work completion time, presence/absence of advance payment, etc.) at a time convenient for you.

Secondly, the customer needs to imagine in detail how the work will be performed from an administrative and economic point of view. You can even draw up a small document with your requirements for the work. And such a document will be called, as in the case of design, “Technical Specifications”. Samples of such a document can be easily found on the World Wide Web. In this document you can, for example, indicate specific hours for performing work. If the object of protection is a hotel, then this requirement will be relevant and justified. Also, one of the requirements may be cleaning of premises (dry or wet) at the end of each working day, with determination of the location for storing waste. Or you, as a customer, can request that a responsible employee from the company be permanently present at your site so that any technical or organizational issues that arise can be resolved at any time.

Third, it will be extremely useful for both the installation organization and the customer to inspect the site before concluding a contract. The main purpose of this event is to check the compliance of the design and actual data of the facility. In practice, it happens that from the moment the execution is completed design work A significant period of time may pass before the start of alarm installation work. This happens especially often at facilities under construction. And during this period, some architectural changes may occur at the site, which they simply forgot to include in the automatic fire alarm project. In such cases, a preliminary examination can become extremely important.
For the customer, this is also a great way to get to know a potential contractor better and an opportunity to see him “in action.” And the contractor will be able to visualize the scale of the upcoming work and discuss some of the installation details with the owner of the facility.

It is clear that such requirements can lead to an increase in the overall cost of performing the work. But if there are circumstances that you consider extremely important when installing a fire alarm, then they must be conveyed to the contractor. And it’s best if your requirements are exactly in writing. In this case, they can be fully transferred to the contract or this Technical Specification can be drawn up as an annex to it.

Fire alarm installation: purchase of equipment and materials

This task can be accomplished in several ways.

First way- supply is entirely handled by the customer. There can be many reasons for such contractual relationships. If during the negotiations the parties came to such a decision, then it is beneficial for them. For the installation organization this is at least convenient:

• no need to spend resources on purchasing and transporting equipment to the site,
• in case of receiving defective or “insufficient” equipment, there is no need to replace it;

This type of cooperation is quite common. In order to buy equipment you do not need any licenses or certificates. But, if the customer decides to take on the role of supplier, then he must understand that any questions regarding the discrepancy between the purchased equipment and the design equipment, as well as possible problems with its replacement or return will fall on his shoulders. If all this does not cause much trouble, then this method can easily be put into practice.

Second way, when the purchase of materials is entrusted to the installation organization, more common. In this case, the installation organization also becomes a supplier for the customer. There are several reasons for this.
Firstly, installation organizations buy equipment for fire automatic systems on an ongoing basis. This means that they know all the nearest trading companies and are guided by the prices of this or that equipment from different sellers. As a result, installation companies have significant discounts from the sellers they work with, so they can also help save your budget.
Secondly, all installation companies have a certain amount of equipment in stock. It is not at all necessary that the installation company will be able to fully provide the facility with everything necessary from its stocks of warehouse equipment. But collecting equipment from your warehouse in order to immediately begin installation work is quite possible. And in a day or two they will be able to deliver everything else directly from the trading company. Convenient, isn't it?
Third, all responsibility for the quality and performance of the equipment will lie with the installation organization. That is, if some equipment turns out to be defective or damaged (which in practice happens much more often than we would like), the installation organization will have to take on the job of replacing it. Moreover, given the availability of a warehouse, most often the replacement occurs instantly and the installation process does not have to be stopped.

Third way Most often used by large companies. It consists of organizing a tender for the purchase of equipment. If you do not have such experience, you may encounter a number of serious difficulties. Probably the most accurate way to organize a purchase would be to contact professional companies that not only carry out these purchases, but will also be able to provide detailed advice. If there are well-designed technical requirements to purchase, you can achieve very serious cost savings. Otherwise, you will still have to spend time and human resources to monitor compliance with the terms of the supply agreement.

Carrying out installation work on site. Alarm installation

After preparatory work You can proceed with the installation.

It's no secret that installing an automatic fire alarm is a process that must meet a huge number of requirements. If the customer has specialists who can monitor the installation process, this will greatly simplify the control task. If there are no such specialists, they can be hired. And then only administrative functions will remain with the customer.
In addition to design technical solutions and the conditions for performing work dictated by the customer, there are a number of requirements that the installation organization must comply with.

1. Since the work is aimed at ensuring fire safety, it must comply with fire safety standards.
2. Installation of an alarm system is a job that is directly related to electrical installation work. And despite the fact that these works mostly relate to low-current systems (up to 60 V), they must meet the requirements for electrical installation work.
3. Do not forget that installation of a fire alarm is one of the stages of construction. Therefore, the installation of alarm systems must comply with building regulations.
4. In addition to all of the above, when working it is necessary to comply with safety precautions and labor protection requirements. There are quite a lot of such requirements. And if the object of protection is a zone of increased danger, then their number increases and becomes tougher at times.

It may seem that so many requirements are simply impossible to meet. But for experienced companies that have been conducting this activity for several years and have equipped several dozen or hundreds of objects with fire safety automation, all these norms and rules are very familiar and are followed at the level of habit. They can competently justify and document every step they take and every action they take. Therefore, when choosing a company as a contractor, do not forget to find out about the experience in this field and the number of completed projects. It would not be superfluous to clarify about working on objects that are similar or similar in their specificity to your object. It is worth noting that installation organizations that care about their reputation prepare separate documents that chronological order reflect the list of iconic objects where the company worked. Such documents are called “Business Reputation”. Customer reviews may be added to this document.

Construction and installation work begins with introductory and initial briefings. Both of them are aimed at ensuring that the work carried out is carried out with maximum attention and is safe for each participant in the production process.

Induction training carried out by the customer. It can take place either orally or in the form of a video presentation. the main objective This briefing is to convey information about the object, its purpose and features from the point of view of safe installation work. An introductory briefing is carried out by a labor protection engineer or other responsible person who performs these functions based on the order of the manager. After the briefing, each employee puts his signature in the briefing log, thereby confirming its completion.

Initial briefing also carried out on site. Unlike the introductory briefing, it is conducted by a responsible representative of the installation organization. And it is aimed primarily at informing workers about labor protection and safety requirements. When performing electrical installation work, which includes installation of fire alarms, these requirements relate to safety when working with electricity, hand and power tools, rules for working at height, etc. If the facility is a high-risk area (gas, oil, metallurgical, etc. industries), then in addition to the general rules, the training is supplemented with inter-industry or highly specialized requirements.

Throughout the entire period of construction and installation work, the customer has the right to monitor and control the process of their implementation. If the customer has questions, he has the right to ask them both orally and in writing. After all, despite the fact that introductory training has been carried out, the customer is responsible for the specialists working at his site. Moreover, the customer has the right to suspend work if he sees violations in their production or non-compliance with labor protection requirements. As a rule, most of these issues are agreed upon through negotiations. In very rare cases, when certain rules are violated systematically, the customer may terminate the contract.

Commissioning work when putting the fire alarm system into operation

After completion of installation work, it is time for commissioning work. The name speaks for itself about its composition. The essence of the work is to launch the mounted system and fix everything possible mistakes installation, malfunctions in the operation of system components, identify possible defective equipment. Also, during commissioning mode, it is necessary to test the system in all operating modes and make sure that it correctly and accurately processes received signals and sent commands.

Commissioning work should not be underestimated, especially if the object of protection is a large building with many systems associated with fire alarms.
Once the system has been fully checked and tested, it is left on for 72 hours. This period is called the “running period”. The meaning of this practice is to identify malfunctions in the operation of the system or its individual components that did not appear during testing.

It happens, albeit in very rare cases, that the customer hires a separate organization to carry out commissioning work. From a legal point of view, this is a completely acceptable measure. But if you look at this from an economic or organizational point of view, then the customer certainly loses. After all, the new contractor will include all overhead costs in the estimated cost, and to attract him, you will again have to conduct a selection process, introduce him to the project and the facility, draw up technical specifications and conduct briefings. Of course, this will take a lot of time and resources. On the positive side Such a step may only be the need to transfer installation work to a new contractor. That is, one specialized organization will be able to carry out an interim assessment of the work performed by another specialized organization. Otherwise, such a “castling” will only create problems. Therefore, in the vast majority of cases, installation and commissioning work is carried out by one organization.

After completion of the work, the installation organization notifies the customer in writing that it is ready for a comprehensive testing of the installed system.

Preparation of acceptance documentation for fire alarms

In order to document the fact of performing any construction and installation work, there is the so-called “Acceptance documentation”. As a rule, it consists of four sections:

1. Permitting documentation;
2. Working documentation;
3. Production documentation;
4. Executive documentation.

These sections are compiled on the basis regulatory documents, state standards and building regulations. Depending on the type of work performed, the composition of the documents varies. Each section is compiled into a separate folder and provided with a register of the documents included in it. First of all, the contractor should know how to correctly and competently draw up the Acceptance Documentation. He, in fact, must develop it and sign it by all responsible persons involved in the work process. A detailed list of documents included in each section of this set is usually reflected already at the time of drawing up the agreement (contract).

After reading all the above information, it may seem that monitoring the installation of an automatic fire alarm on the part of the customer is an extremely difficult task. Especially for those who are faced with the need to equip a facility with fire-fighting automation for the first time.

Before installing a fire alarm, you need to understand the types of such systems and choose the type that suits your specific requirements. You can install the system yourself, but it is better to call a special team. If desired, the owner of the system can register it with the State Fire Supervision Authority.

Types of systems

All types of fire alarm systems can be divided into several types.

1. Threshold systems with radial trains.
2. Threshold systems with a modular structure.
3. Combined system.

Threshold systems with radial stubs

Threshold systems equipped with radial loops are popular for one reason only - they are very cheap. However, installation of such equipment will be quite expensive. Such a system has a lot of shortcomings that are difficult to notice immediately after installation.

In particular, the PKP can give false signals. The number of such false notifications here is an order of magnitude higher than in any other devices. At least two detectors must be installed in one room, and this leads to increased costs. Although the equipment is very economical, its installation and the expense of unnecessary detectors will lead to the fact that the total costs will be very significant.

With an abundance of sensors, it will be impossible to track them from one computer.

The control panel also sets a certain threshold at which a signal is given. It is almost impossible to check the serviceability of the alarm; if it breaks, the sound may not sound. PEP is highly dependent on the human factor.

In a word, such a system has many more disadvantages than advantages. When installing an alarm for serious purposes, it is better to choose something else.

Threshold systems with a modular structure

Such systems are inexpensive, like the previous type of alarm. They have almost the same disadvantages: expensive installation, a certain signal threshold, dependence on the human factor.

However, this type of alarm can be freely controlled from one remote control or computer. In addition, here it is possible to install two blocks simultaneously.

This system has a fundamentally different structure than the previous two. It works differently. All sensors in it are combined into a common unit, and they are regularly checked from the control panel. Signals from sensors can have four responses: “normal”, “fire”, “malfunction”, “absence”.

The disadvantage of this type of alarm is that they detect the source of fire too late and report it. Otherwise it's a very good system.

This system has an optimal price-quality ratio; using the survey panel, you can always identify faults in the sensors in a timely manner, as well as obtain a lot of useful information.

One loop of such an alarm can include up to two hundred sensors. To appreciate all the advantages of this system, you need to understand how this type of fire alarm works. It assumes the presence twisted pairs, this is its main advantage and at the same time a disadvantage. When any sensor fails, the system itself remains fully operational.

The sensors do not have any specific signal threshold. They simply record the atmosphere at their designated point and send the data to the control panel. This allows you to very quickly identify the source of fire. In addition, such a system design allows you to find out about any faults in the network in a timely manner.

The cost of installing an analogue addressable system itself will not be expensive, but the equipment will cost a decent amount. Probably the only drawback of this signaling is that the protocol requires a twisted pair cable.

Combined systems

Combination fire alarms are the most powerful. They allow the installation of several thousand sensors and devices. They have a very wide range of additional equipment.

Fire alarm systems and devices of this type are controlled from one control point, which greatly facilitates safety monitoring. There are practically no disadvantages to a combined fire alarm, except that it can cost a decent amount of money.

Installation and dismantling

Installation of an alarm requires compliance with special rules that are prescribed in regulatory documentation. It is advisable to install such systems with the help of professionals if the owner of the premises does not have the skills to work with such systems.

Some owners ask the question whether it is possible to create a fire alarm with their own hands, that is, assemble the device itself at home. Yes, this is quite possible, but within certain limits. It is impossible to create complex systems on your own. A master can only do the most simple devices, and no one can guarantee that they will function properly.

Sometimes the fire system operates without any fire. The frightened owners do not know how to turn off the fire alarm. The sound of this system is very specific and hardly anyone will like it. To restore silence and order, you must do the following.

1. First you need to find out the reason why the alarm went off. There may have been smoke or a small fire. The room must be ventilated immediately.
2. If, after all, the system worked without any reason, then you need to decide on its type. The simplest alarm system with sensors can be easily turned off. To do this, you just need to remove the power source from the sensors themselves. For a more complex alarm system, you need to go to the control panel. The system often turns off only after the appropriate code has been entered.
3. A radical way to eliminate noise is to cut through the alarm wires. If you need to restore it, you will have to carry out a whole series of works.

Why do you need to install a fire alarm?

Installation of a security and fire alarm system (FS) will save not only your property, but also your life, as well as the lives of your loved ones or employees of the organization where you work. In terms of damage, fire is more dangerous than burglary and other crimes, so take the choice of a fire alarm system seriously.

We will install fire alarms (installation of fire alarm systems) and installation of warning and fire evacuation systems (SOUE).

What is market price fire alarm?

In this case, everything depends on the complexity of the system, on the selected equipment (domestic or imported), on the wishes of the customer, for example, if the interior should not be damaged, then it would be better to install a radio channel system. You can find out the approximate cost of the system using our calculator.

The calculator on the website calculates the cost is too high, is it possible to get the service cheaper?

How long does it take to install a fire alarm?

We always try to reduce the installation time for fire alarms as much as possible. If the facility is planned to be put into operation in the near future (workplaces are not occupied), then, as a rule, all work will take no more than 1 month, including the design and installation of a fire alarm.

Can your specialist go to the site for inspection?

We are always ready to go to the site. This service is free! But, initially, it is advisable to send us email floor plans to determine the preliminary cost of fire alarm installation work.

Do not read if you are ready to pay fines to government agencies

Until relatively recently, managers of enterprises and institutions - owners of private businesses with any real estate - did not have to seriously worry about the presence of a fire alarm in their premises - fines for its absence or improper operation were relatively small, which meant that it was easier for many of them to pay off from the state than to worry about installing modern fire protection systems. The situation changed on May 25, 2011, with the Parliament's approval of presidential amendments to the Code of Administrative Offenses of the Russian Federation related to fire safety issues.

According to the new standards, for violations associated with evading the installation of fire warning systems, much more serious liability is provided: violation of fire safety requirements for fire alarm systems entails the imposition of an administrative fine on legal entities in the amount of one hundred fifty thousand to two hundred thousand rubles.

One cannot but agree that 200 thousand rubles. - a very serious amount, the immediate loss of which can cause serious damage to any small business, which, by the way, is the object of constant inspections by supervisory authorities, which successfully replenish the state budget with astronomical fines levied on negligent entrepreneurs. Should I delay installing a fire alarm system? – The question is perhaps rhetorical... The argument in favor of professional installation of systems is by no means solely the fear of being fined. Let's not forget about their immediate purpose: timely notification of a fire, which will save not only property - ours and others', but also, possibly, human lives!

Most people naively believe that fire alarms are installed only on manufacturing enterprises– for example, in workshops where, due to the operation of powerful electrical equipment, machines and units, there is a high risk of fire. However, as statistics show, up to 80% of fires occur not in production, but in the residential sector and at social infrastructure facilities. Industrial premises with rare exceptions have long been equipped automatic systems fire alerts.

Thanks to a fire alarm, you can not only effectively notify people in the room about the danger, but also prevent the fire from growing or extinguish it as soon as possible. early stage. In almost any facility, including a modern apartment, there are a lot of objects and devices that are prone to fire. In addition, in old buildings, worn-out wiring is an additional risk factor.

Installing the system is a complex job that requires highly qualified specialists. Proper installation of the system guarantees its reliability uninterrupted operation and long term trouble-free operation. However, it should be assumed that only professional installers under the guidance of a competent engineer can meet all the necessary requirements of GOSTs, SNIPs and NPBs. Modern systems fire alarms - very complex devices, usually computerized - with the possibility of programming various functions. Therefore, when connecting central equipment and sensors, the participation of an experienced engineer is required, and at the commissioning stage, the participation of specialists who have undergone special training at equipment manufacturers is required. Hence, an amateurish approach to installing an alarm system is fraught with inevitable problems.
