Automatic fire alarm installation. Installation of a security and fire alarm for a home: installation features Installation of a fire alarm

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

The safety of any premises depends on the correct installation of fire alarms. Incorrectly performed installation work not only will not protect the building during a fire, but 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 I suggest using the following sensors in fire alarm systems:

• optical;
• smoke;
• thermal.

Optical sensors are capable of capturing infrared or ultraviolet radiation, which are released during the combustion process. Smoke sensors react to the occurrence of increased smoke, and thermal sensors react to a sharp increase in temperature. Often, for the reliability of the system, devices of different types are combined.

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

This system is quite complex, so the installation of a fire alarm can be carried out if there is project documentation, which takes into account the purpose of the object.

The design, connection and maintenance of the alarm system is allowed to be carried out only by those companies that have certificates and licenses to carry out these works.

In the preparation of project documentation, they develop technical task. It is further used to make the layout of cables and devices.

Norms and rules of installation

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

You can get acquainted with the full list of rules in GOST and SNIP. In addition, attention should be paid to the Federal laws on which the project documentation is based. It is also necessary to comply with the requirements fire safety.

If installation requirements are not met, dismantling is necessary. installed equipment and carry out all work in accordance with the regulations. Dismantling in this case is carried out at the expense of the contractor.

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

• fully comply with the project documentation and the specifics of the premises;
• quality work performance.

In a protected building, it is advisable to divide all premises into several control zones, each of which is equipped with a certain number of sensors.

Power supply norms

Power and communications networks also pay Special attention. After all, they must be resistant to fire. When the room temperature rises, their insulation must be maintained.

Communication and power wiring must be laid in different channels. In places where they intersect with the mains, they must be equipped with additional reliable insulation.

The central control panel must be placed in a certain room. Access should be limited. service 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 the installation of fire alarm systems on their own. 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. Independently, with skills in working with such systems, you can assemble a system for the home. Complex structures should be carried out only by specialists who give a guarantee for 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. Water supply in case of fire should be at least 30 minutes, and the distance between sprinklers should be no more than 4m.

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

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

The cost of performing work on installing an alarm system 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 is completed, the executing company and the customer need to draw up a code executive documentation. It is necessary to prepare the following documents:

• magazine and executive schemes;
• acts of statements and tests, surveys of hidden works;
• quality passports of the materials used, their certificates;
• working drawings.

Complete list of all required documents can be found on the website of the Ministry of Emergency Situations.

How to turn off 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 can work 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 it off? After all, an unpleasant specific sound is often made. To disable the alarm, you must:

1. determine the cause of the alarm. 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 the cause is not observed, then it is necessary to turn off the device. Simple alarm it is enough just to turn it off by turning off the power source from the sensors. Complex involves turning off the system from rooms with a central control panel. In this case, you will need to enter a specific code;
3. a radical method of eliminating unpleasant sound is to cut the wires. But remember, in order to restore the operability of this alarm, in this case it will be necessary to carry out a number of consecutive works.

To implement various complex tasks for the security of the facility, including special place occupies the installation of alarm systems and video surveillance, you should contact a specialized organization that has a license for these types of work.

It is best to use the installation of turnkey systems, because this is the only way to take into account all the requirements of customers as much as possible. This solution is suitable for a small security company, a large construction organization, a corporate client or an individual.

It is known that the installation of fire and security alarms must be carried out in strict accordance with all approved design documents.

Pictured is the setup process.

The installation of the fire alarm system itself is carried out in several stages, and it is better to start it when the required level of construction readiness has already been reached at a particular facility. Thus, it is possible to significantly reduce the time for putting the finished object into operation, reducing the costs of customers for finishing work.

Each fire alarm installer must be suitably qualified and professional experience. It is very important that he owns all modern techniques and working technologies.

Using specialized tools during installation work, you can ensure a neat and quality installation OPS. This is very important when connecting equipment at facilities that have previously undergone cosmetic or major repairs.

During the laying of cables, when the OPS is being installed, it is necessary to use only high-quality materials produced by well-known companies, which ensure a fairly reliable operation of all equipment, as well as an aesthetic appearance of communications.

When installing fire alarm systems, you can use wireless devices and completely abandon the work associated with laying cable lines.

The video shows the tools that are needed for installation:

What should you pay attention to when choosing a contractor?

When installing the OPS, it is very important to strictly follow all the recommendations provided by the manufacturer. You also need to pay attention to the following points:

• When choosing a contractor, you should find out whether the employees working in this company and performing the installation of fire alarm systems regularly receive appropriate training. This is the only way to ensure compliance with absolutely all requirements for high-quality and reliable installation of the mechanism;
• Particular attention should be paid to the choice of equipment for security and fire systems. It should unobtrusively and harmoniously merge into the interior of a particular object;
• The contracting company must have sufficient experience and capabilities. In this case, it will be able to guarantee the effective implementation of all complex systems security, its configurations, as well as take into account all the specific wishes and requirements of the customer.

Features of installation and maintenance of equipment

It is known that the security and fire alarm is the right and right step towards complete peace of mind. By using modern means smoke detection and temperature control can detect any short circuit, fire or smoke.

Each object needs a high-quality security and fire alarm system. The tenant or owner of the premises must ensure its installation if the building is owned by a legal or private person.

It is known that the installation of alarm systems is a rather complicated process and, first of all, it is necessary to develop a plan for the installation of signaling units and sensors. Only by correctly positioning the detectors, you can use their own sensitivity to the fullest and reduce the number of false alarms of mechanisms.

During the installation of systems, special attention should also be paid to correct location sensors. It is recommended to cover the maximum area of ​​the object with active fire detection elements.

Only using high-quality materials during installation, it can be guaranteed that the fire alarm system will last for a long time, and the communication between the alarm system and the sensor will be reliable.

The video shows the installation of ops:

System design and implementation

Design is considered necessary step, from which the installation of the OPS begins. It is better to involve professionals at the same time, because it is very difficult to draw up a project on your own, and then implement it on the site. It is known that competent design is considered the key to correct operation alarms. Since a fire is an extreme situation, it is very important that the device clearly and quickly notifies the source of ignition.

Fire alarm installation also includes the installation of an active fire detection system. Qualitatively performed work affects the functioning of the entire system without failures.

When fire protection systems are installed, communications are laid, an alarm system is connected. Separately, you can connect the alarm to a specialized system automatic extinguishing fire.

What affects the cost of installing equipment?

It is known that installation prices vary greatly. The cost of work depends on several factors:

• Equipment used for installation;
• The complexity of the installation work.

The cost of installing systems is determined at the very first stage, when a specialist travels to assess the facility.

Much depends on the type of object, as well as the requirements of the client. For example, the operation of cameras in poor lighting conditions is only possible with infrared illumination.

For video surveillance systems, it is very important that video cameras that are installed on the street are sufficiently well protected from snow, rain, and temperature extremes.

Installation of a fire alarm system is a mandatory stage in the preparation of an object before commissioning.

Increased requirements are imposed on the protection of premises from various emergencies, therefore, without technical means fire safety is indispensable.

How to put?

Currently, the service - installation of a fire alarm - is offered by many companies both in Moscow and in other cities. Offers vary in price, terms, types of equipment used. In addition, on the OPS market, you can find technical means that do not require special knowledge, which the owners of the facility can install on their own. But before making a choice in favor of a particular company, as well as self-assembly, it is necessary to take into account a number of nuances:

• Installation of fire protection systems is a licensed activity - the installation organization must have an appropriate permit, and self-installation possible only on objects of individual use;
• The presence of a strict regulation- each category of premises, buildings, structures has its own requirements for the level technical support fire protection;
• The specifics of the object, both constructive and operational, affect the choice of equipment and the order of its placement.

Calculator for calculating the cost of installation by area

Installing a fire alarm system is a task for specialists who will calculate all the risks and carry out work in strict accordance with regulatory requirements. Here it should be remembered that the designers and installers of fire alarm systems are responsible for the quality of the work performed. And this is a very weighty argument to entrust the installation of fire alarms to trained people. At the same time, you should not abandon the installation just for the reason that it is necessary to involve specialists in the work. For small objects, for example, an apartment, a garage box, installation can be performed on their own with ready-made kits. But even in this case, it is worth inviting a specialist who will select the equipment that is suitable for this particular room. And only on the basis of his recommendations it makes sense to acquire technical means and install them.

On what objects to put?

Each owner of a premises of any purpose is responsible for ensuring fire safety requirements in it. The volume of requirements depends on the type of object, the order of its use, location and a number of other factors. For a significant number of premises, primarily for public purposes, it is provided mandatory installation fire warning equipment. It can be both local in nature for informing about a fire, or included in the complex for transmitting an alarm signal to the fire department.

In relation to objects that are not included in the list, where the installation of a security and fire alarm system is mandatory, the decision on the appropriate technical equipment accepted by the owner. Often they do not consider it necessary to install even the simplest stand-alone detectors. But arbitrage practice in cases of fires, it is not in favor of such owners, because they are responsible for ensuring fire safety, the courts come to the conclusion that the absence of an OPS is a fact of insufficient fulfillment of this obligation, therefore, the fault of the owner of the premises in non-compliance with fire safety requirements is obvious. Such circumstances make the installation of a fire alarm system a mandatory procedure that can really protect against many negative consequences.

Work order

Installing a fire alarm system involves several steps:

• Inspection of the object;
• Development of a project with the definition of a list of equipment;
• Preparation of the object for installation;
• Installation work;
• Commissioning works.

Only this A complex approach for installation will allow to form effective system fire alarm. It should be noted that at present such systems are of a complex nature and are designed to alert not only people in the building, but also emergency services about a fire.

Do not forget that the structure of the OPS also includes technical means for ensuring evacuation. Previously, they were only special signs of evacuation routes. At the present stage of development of technical means of protection and safety, fire safety components are integrated with other complexes, for example, access control and management, thereby forming single system emergency protection. Such a system provides for constant technical monitoring of the state of all objects, timely transmission of a signal about an emergency situation, remote dispatching of various engineering communications. According to experts, a standard fire alarm on analog equipment can reduce the time of fire detection by three times, and in combination with equipment automatic fire extinguishing can ensure the localization of the fire before the arrival of the first fire brigades.

Practice shows that correct installation security and fire alarm, specialized organization ensures long trouble-free operation of the equipment. And the installation of all devices does not end the work at the facility for the installers. any technique needs periodic maintenance. The complexity and scale of its implementation depend on the technologies used, as well as the characteristics of the facility. By the way, even the most primitive equipment installed on its own needs regular maintenance. It is desirable that such work be carried out by specialists who will not only ensure the operability of technical security equipment, but in the process of maintenance will eliminate the shortcomings of self-assembly.

Equipping buildings with a fire alarm system is an urgent need on which the lives and health of many people depend, which is much more expensive than any installation costs.
