In this article, we will talk about how the correct installation and installation of a fire alarm goes. Immediately, we want to note that such an installation requires the presence of certain knowledge!

For convenience, we have divided the article into the following components:

Correct installation of fire alarms

First, you need to develop a project that describes the main nuances during the installation of a fire alarm. First, the place where the control point is located is determined, and then the methods of conducting communications. You also need to familiarize yourself with the presence of fire extinguishing modules, types of sensors and other information. But it must be borne in mind that signal wires should never be near a heat source. Control equipment and sensors should be installed only in those positions where there is less chance of touching them and causing damage.

Then you need to install the equipment, so you need to decide in advance on the complexity of the fire alarm. It depends on the level of risk of fire in the room, which can be completely different. If the room has a small area, then you need to install conventional alarm systems, but if the object has a large area, then you need to install an address system. The fact is that the address system quickly identifies the place where the fire occurred, so it is preferable. You will not have to spend a lot of time looking for the premises in which the fire occurred.

The analogue addressable system is the most popular in recent years. All this is due to the fact that special sensors make it possible to find out the change in temperature and even the level of smoke in the room. In principle, each fire alarm system provides detailed information about the state of the room, because there are many sensors in the room that have a common connection using loops, which makes it possible to connect to a computer and configure. If the sensor finds a signal, then a light or sound alarm is activated. If the fire alarm has special modules that start extinguishing the fire, then the control system will definitely activate it.

Features of installing fire alarm sensors

A smoke detector is a fire alarm detector, it is an extremely simple device. It is small in size and is fixed to the ceiling or wall in the apartment. There are two main types: photovoltaic and ionization. Photovoltaic is triggered when smoke passes between the photo and the LEDs. And the ionization is started due to the ingress of smoke into the current that passes between the wires. It is impossible to say for sure which of the options is preferable, since the ionization one is turned on due to a strong fire, and the photovoltaic one because of the huge amount of smoke. Therefore, our online magazine site believes that the best option would be to use two sensors at once.

It is recommended to install sensors between places where a fire can start without any problems. For example, in the kitchen while cooking. Installation in living room, bedroom, corridor and other places is also recommended. Keep in mind that extra protection never hurts. However, the installation in the kitchen requires special installation, because the humidity there is steadily increased, so the sensor may be triggered erroneously. Be sure to install the unit as far away as possible from batteries and heaters, fluorescent lights, vents, and so on.

Almost all fire detectors use batteries for continuous operation, so it is advisable to play it safe and check them as often as possible. You can check the sensor itself, it is simple to do it - move the lighted candle directly near the sensor, and the fire will provoke its activation. Remember that dust on the sensor can muffle its action, so wipe it down as often as possible.

Almost always, a fire safety sensor is mounted in the ceiling at a distance of 300 mm from lighting devices and walls. The wall model is installed at a distance of 200 mm from the ceiling so that there are no empty air spaces where smoke stops circulating and the sensor can be activated. If the ceiling has cross beams with a thickness of about 10 centimeters, then the sensor must be fixed to the base and not between the beams. With a large thickness of the beams, if it exceeds 10 centimeters, contact a specialist.

Absolutely all floors must have sensors. The first is installed above the base of the stairs, the second in the middle of the hallway, the third on the ceiling in the bedroom, and so on. Then additional sensors are installed in the hallway, living room, kitchen and other places where there are electric heating appliances.

What wires to use when installing a fire alarm?

Before choosing cables and wires, you need to study the requirements that apply to them in Russia. During the installation of a fire alarm, it is necessary to lay the loops so as to automatically monitor their condition along the entire length. As a rule, loops have wires with cores made of copper. If during installation you do not think about the fact that you will control fire extinguishing installations automatically or a smoke extraction system with voice notification, then you do not need to allocate an additional communication channel. If such management is planned, then you must conduct a communication channel and connecting lines made in the form of telephone cables.

Connecting lines with telephone or control wires should have an additional loop margin of about 10%. It is also possible to connect radial loops directly to the fire device, but only if the information capacity does not exceed 20 loops. But if the alarm is of a ring type, then the end and the beginning are connected directly to the terminals that are located in the receiving and control device. Do not allow corrugation in the box and hose if the wires have extremely high voltage. If the parallel installation has a voltage of about 60 volts, then there should be a distance of about 0.5 m to the lighting and power devices. Do not forget that it is advisable to divide the loops into segments and use junction boxes. Installation is best done in an accessible place at a suitable height, especially for a device installed at the end of the loop, because it allows visual control during operation.

Fire alarm installation rules

Control devices together with control and monitoring devices must be installed in the area where the duty personnel are on duty every day. Of course, sometimes it is quite possible to install on site without personnel, if there are reasons for this. For example, if there are no employees who are on duty 24 hours a day, but there is another point that receives information about what is happening at your facility. That is why in the room where you install the sensors, you need to make sure that the fire and burglar alarms work correctly, and unauthorized access is prohibited.

The amount of capacity in the receiving and control devices and the number of loops that are needed to work with fire notifications should be about 10 pieces and 10 percent. Control and monitoring devices must be mounted on walls, structures and partitions that do not contain combustible materials. Installation of such equipment is quite realistic on structures that are made of combustible materials, but only if they are covered with a steel sheet with a thickness of about 1 millimeter or other non-combustible sheet material with a thickness of about 10 millimeters. It is very important that the material protrudes about 10 centimeters beyond the contour of the equipment being mounted.

Do not forget that the distance from the upper edge of the control panel used to the ceiling of the room, which is made of non-combustible materials, should be about 1 meter. With the adjacent position of the control and monitoring devices in the amount of several pieces, as well as control devices, it is necessary that there is a distance of about 50 millimeters between them. You also need to take care of a sufficient height, since the control panels are installed in such a way that the distance to the operational controls is about one meter.

A room with a staff or a fire station must be located on the basement or ground floor of the building. You can arrange a room above the first floor, but on condition that the exit will be in the corridor or lobby. Also, the exit must adjoin the staircase so that there is a quick exit to the outside of the building. The distance from the premises of the fire station to the room with personnel who work daily for 24 hours must be at least 25 meters. It is very important that the premises meet the necessary characteristics:

1. The minimum area is 15 square meters, preferably more.


2. The air humidity is 80%, and the temperature is about 18-25 degrees Celsius.


3. Artificial and natural lighting should be comfortable. Be sure to get emergency lighting.


4. Illumination should be as follows: natural - 100 lux, artificial (fluorescent lamps) - 150 lux.

How can you get a fire alarm license?

To obtain a license for the maintenance, installation and repair of automatic fire alarm devices, as well as automatic fire extinguishing systems, you need to fill out the necessary documents and spend a lot of time. For example, if you register your company or want to run a staff in an office where there is an increased risk of fire, then you need to first decide on the system itself. Perhaps a certain automatic fire extinguishing system will suit you better than another. Next, fill out a certificate in which you indicate the material and technical base and write down all the mechanisms and machines with the nomenclature and full volume that will be needed to carry out the work. A very important nuance is that you need to assess and check the material and technical base during the preparation of the act, which demonstrates the assessment of compliance with the conditions, requirements and the license as a whole.

Next, think over a system for leading work control and determining its quality. Here you will need to provide a copy of the manual for the use of devices, a certificate from production, where the control forms will be demonstrated, and so on. Control forms can be output, input and operational. After that, you need to write an application and submit to the authority that issues the license. When filling out an application, it is very important to take into account the legislation of Russia in relation to the activities of your organization.

An important role is played by the working personnel and their qualifications, so you must provide data on the qualifications of all employees who will provide services on this equipment. To check the qualifications of your staff who will be servicing and install new equipment that guarantees safety from a fire in the room - check their education, for example, check their skills on tests or just look at the very existence of secondary, higher or special education. Experience and work experience is also very important, since, according to the law, only people who have worked in the EMERCOM of Russia for at least five years can be engaged in servicing such equipment. Obtaining a license depends on how conscientiously the employees got a job, and if the experience and education are forged, new personnel will have to be recruited.

Any organization needs a fire alarm and additional equipment that can fix the location of a fire. You shouldn't skimp on equipment and maintenance, because if the circumstances are unfortunate, you can lose absolutely everything.

Fire alarm is a complex system in which different types of devices interact in an orderly manner: control and monitoring devices, sensors, warning elements, communication lines, autonomous power supplies, peripheral equipment. Installing equipment is not easy - you need to know the features of installing a fire alarm.

According to the current legislation, industrial enterprises are required to have fire protection on their territory. Many owners of private houses and apartments also prefer to use precautions. Experts recommend: before installing fire alarm systems, you need to decide on their type.

Simple and complex equipment

Fire alarm systems differ from each other in configuration and functionality.

They are different:

1. Threshold equipment equipped with radial stubs has become widespread due to the low cost of its components. The name is based on the principle of operation of the device. The main control unit serves sensors with an individual sensitivity threshold. Fire alarm installation involves the use of several units of detectors per room. The main disadvantage of the installed equipment is the increased level of false signals.
2. Threshold signaling with modular structure is similar to the previous scheme. The difference is that one control panel simultaneously controls the operation of communication lines, and installation and operation are designed for the use of two units.
3. Addressable polling devices have a different structure compared to the previous versions. The operation of the sensors is monitored by a module with a ring loop, which allows you to filter out unnecessary information. The alarm circuit is reliable and easy to design.
4. An analogue addressable line is a modern device. Each detector has an individual address, where it sends a signal about its operating status. The sensors have twisted pairs. If any element fails, the system will continue to function.
5. The combined system is installed indoors and outdoors. It is powerful, has a ring circuit using threshold and analog devices.

Fire alarm installation regulations

Fire alarm installation is carried out in accordance with GOST. Regulatory papers regulate the drafting of a fire system, the parameters of its elements and installation, including construction aspects. The basic rules are specified in the document on the means of security and fire alarm systems.

According to the regulations, design and installation should be focused on ease of maintenance, repair and protection from damage. The OPS is installed in each room using at least two sensors, except for stairways and bathrooms. A number of documents contain specific standards for different types of devices.

Substation installation / assembly rules

Installation of security and fire alarms depends on the area of ​​the room and the height of the ceiling structures. Each device has its own installation and operating instructions.

However, there are general installation rules:

• The selection and adjustment of the central control unit is carried out in accordance with the instructions. Simple models have multiple input connectors for connecting sensors. Output lines enable devices to be switched on that signal a hazard. Complex circuits additionally have a security function. For simplified installation, you can purchase a wireless fire and security system kit. It contains all the necessary components, including the fasteners.
• The laying of communication lines should be carried out in accordance with the requirements of SNiP. Only wires with copper conductors and heat-resistant winding are used. For internal installation it is necessary to use a corrugated pipe. Each loop has a specific marking. The wires are subject to inspection along their entire length. For sensors, it is better to use two-wire and four-wire versions. Installation of OPS assumes 10% of the stock of loops. According to the rules, the laying of connecting wires with power cables is unacceptable. The distance between the signal wires must be at least half a meter.
• Fire detectors control a specific sector, therefore they are mounted in places where open fire appears. According to the norms, they should be at a distance of 9 m from each other, not more than 4.5 m from the corners of the walls, not less than 0.2 m from the ceiling. Heat sensors are located where the temperature rises sharply, with the exception of places where heating devices are used. Linear sensors must be installed on opposite sides of the room.

After measurements and selection of the location of the sensors with the central control unit, the fire alarm system is installed.

How to install - do it yourself or through a contractor?

Correct installation of security and fire systems ensures the safety and security of property. According to the law, the design and commissioning works in the complex are carried out by specialized organizations that have permits from the Ministry of Emergency Situations. They conclude an agreement with the customer and for the maintenance of the security and fire alarm system.

Installation of systems is carried out on the basis of approved documentation. Specialists in a short time are able to install a fire alarm with an extensive network of devices and logic circuits. People who are versed in electrical engineering can do a simple DIY installation of fire systems. A well-designed scheme is easy to legalize.

Before carrying out the installation of security and fire systems with your own hands, you need to choose and buy a certain type of alarm. If financial capabilities do not allow this, then the device can be made independently.

In this case, the alarm signal will be sent to the owner's phone, and not to the central console of the Ministry of Emergency Situations. You will have to call the fire department separately. Household fire alarms require some nuances to be taken into account:

1. the use of a multicore cable in the winding to connect the sensors;
2. the use of reed or chip sensors that are installed on door or window openings;
3. placement of sensors in accordance with the design of the ceiling in accordance with established standards.
4. system connection according to the instructions.

Recommendations for choosing a contractor - what to look for?

The installation and maintenance of fire alarms requires a serious approach. This work should be done by highly qualified and experienced professionals. When choosing an executing company, you need to consider:

• availability of a license;
• stages of the organization's activities: studying the characteristics of the premises, determining the type of alarm system in relation to the object, designing, calculating the cost, installation;
• whether the company is in the National Association of Self-Regulatory Organizations SRO or not.

How much will the installation cost?

Fire alarm calculations depend on its configuration and the effective operation of its constituent elements. High-quality equipment quickly responds to the appearance of the primary signs of a fire.

Unreliable settings often lead to false signals. Each licensed organization determines the scope of work and forms the total cost.

Payment depends on many factors:

1. the area of ​​the room;
2. the type of system installed at the facility;
3. the level of its complexity;
4. branching;
5. control method: automatic or manual;
6. characteristics of electrical work;
7. additional costs for materials.

Conclusion

Installation of fire alarm elements has its own characteristics. Before starting to install a system, it is important to determine its type and complexity. The equipment and equipment costs depend on this. These types of work are performed by licensed organizations employing qualified designers and engineers.

At home, you can independently mount a simple fire alarm. Any installation of the system is carried out in accordance with the regulations and requirements of GOST. The basics for the installation of alarm elements are specified in the normative documentation. For each object, the cost of services is calculated individually.

Video: Fire alarm installation

Today, no industrial enterprise or office building operates without fire-fighting equipment. And this is due not only to mandatory regulatory requirements, but also to a healthy desire to save people's lives and material property. Installing a fire alarm is a crucial step, so it is important to choose the right equipment, taking into account the characteristics of the protected object, and carry out the installation according to the rules.

Fire-fighting equipment of facilities is carried out in several stages:

• project preparation;
• selection of equipment, taking into account the requirements of the facility;
• laying of cables;
• connection of fire detectors;
• setting up and starting the system.

Fire-fighting equipment is installed in any type of premises, except for staircases, bathrooms and other objects with high humidity.

A fire alarm is a chain of interconnected devices, each of which performs a specific function. The standard set consists of sensors, warning devices, a reception and control point, and an autonomous power supply. If desired, the complex includes devices for automatic fire extinguishing.

The main element of the fire alarm system is sensitive sensors. Their role is to track critical changes in the indoor climate and transmit an alarm signal to the control point. Having received a signal, the control device turns on warning devices (siren, light annunciators) or activates automatic fire extinguishing (gas or water). At the same time, an alarm signal is sent to the Ministry of Emergency Situations or the fire department.

Depending on the intended purpose, detectors are emitted that react to smoke, flame or temperature rise. When choosing sensors for a room, it is important to give preference to quality products that will not fail in a dangerous situation. By the way, a variety of models will allow you to choose devices that will organically fit into the design of the room.

Fire alarm connection: equipment selection

When choosing a fire alarm configuration, it is necessary to take into account the parameters of the room for which it is intended. Namely: area, ceiling height, fire risks, number of personnel and visitors, materials and equipment.

Such an analysis will make it possible to make the right choice in favor of one of the presented types of fire alarms:

• Threshold with radial trains. Despite the affordable price of the equipment, it requires considerable costs for installation. The operation of the threshold system is marked by periodic failures and false alarms. To increase the efficiency of the system, the number of sensors increases, but then an additional computer will have to be installed to monitor its operation. And this will also lead to a rise in the price of the complex.
• Threshold with a modular structure. The difference between this type of alarm and the previous one is that its operation can be controlled from one point. Otherwise, it has similar disadvantages.
• Address-polling. A reliable type of equipment that is fundamentally different from the previous ones. The system consists of many detectors connected to a common unit. The control point collects operational information from sensors about the situation in the monitored sector. The main advantage of such devices is quick troubleshooting.

• Analog addressable. Up to 200 sensors are connected to the control unit simultaneously, which affects the reliability of the complex. Moreover, if one of the detectors is out of order, this will not disrupt the operation of the complex as a whole.
• Combined. Such an alarm is capable of providing security at large facilities. It allows simultaneous connection of several thousand devices. One control unit is sufficient to monitor the operation. The only drawback of installing such an alarm is its high cost.

Important! The first criterion for choosing an alarm is the size of the room. For large objects, an address system is suitable, since only it can accurately determine the place of fire.

There are separate installation and operating requirements for each type of equipment. In this case, we can separately highlight the rules common to the installation of all types of alarms:

• Each fire alarm has a control unit with connectors for connecting devices. In the simplest system, sensors deliver a danger signal, and the central device, in turn, turns on detectors to warn people.
• In complex models, it is permissible to integrate a security function into a fire alarm.
• It is necessary to observe the permissible distance between the cables of the fire alarm and the power supply of the object. This will avoid interference and false alarms.
• If you purchase a wireless fire fighting kit, installation will be easier.
• It is allowed to use wires only with thermal protection, and it is necessary to control their integrity along the entire length.
• The sensors are located in places where the temperature may rise, but their installation near heat sources is unacceptable.
• The detectors are mounted at a distance of 9 m from each other, but up to 4.5 m from the corners. The average distance from the device to the ceiling is 30 cm.

Before drawing up a fire alarm project, it is important to measure the room and determine the exact location of the sensors.

Note! A deposited layer of dust can affect the performance of the detector. Therefore, it is recommended to wipe it down as often as possible.

According to the legislation, the installation and adjustment of fire-fighting equipment is carried out by organizations that have received a license from the Ministry of Emergencies. In this case, an installation contract is concluded between the client and the contractor. The work is carried out on the basis of the approved project.

But to protect your own home, with the appropriate knowledge in the field of electrical engineering, it is allowed to independently install simple alarms. After setting up the equipment, a signal about the incident will be sent to the owner's phone. But he will have to call the fire department on his own.

Installation of fire alarm systems by contractors

An important requirement for the installation of fire protection systems is the involvement of contractors with a valid license or obtaining permission from the regulatory authorities.

The safety of people depends on the correct installation. Therefore, when choosing a contractor, it is important to consider the following factors:

• availability of a valid license from the Ministry of Emergency Situations;
• the organization's presence in the SRO association;
