In the modern world, reliability and safety have long been synonymous with peace of mind, which is why fire alarms are the best solution for protecting commercial and residential premises. Fire alarm systems are a whole integrated complex of fire and security systems that prevent unwanted entry into the premises and prevent the occurrence of fires.

When faced with a choice between an integrated fire alarm system and separate systems, it is better to immediately pay attention to the fire alarm complex. It is not only much more profitable to maintain, but also more convenient to operate. The convenience of control lies in the fact that the equipment of security fire systems in control is displayed on one remote control, which allows you to simultaneously monitor a number of violations at once: fires, unwanted penetration, etc.

Fire alarm systems divided into several options, the choice of which is a purely individual matter. It should be noted that when choosing a particular system, it is worth considering the specifics of installation and maintenance. It is these details that will help you make the right choice and choose the option that meets all your requirements.

Addressable fire alarm systems

Addressable fire alarm systems are understood as a combination of technical elements of a fire alarm to turn on a fire alarm, and it can be either automatic or manual. The signal goes to the control panel from the detectors, which are located in rooms that require protection. Addressable fire alarm systems are relatively low cost and provide the ability to quickly respond to emergencies, thus avoiding major problems.

Radio channel security systems

Radio channel security systems are devices aimed at creating a workable security and fire protection system. The convenience of the radio channel system mainly lies in the fact that it can be placed even on complex sites with several buildings or an unusual layout. The signal goes through radio waves, which avoids dependence on the integrity of cables and the busyness of telephone lines.

GSM alarm

The GSM system is a combination of a gsm alarm device and fire and security detectors. Efficiency and instant notification is the main advantage of GSM Monitoring. Timely notification and quick response can reduce damage and risks to a minimum.

According to the current regulatory documents of the Russian Federation in the field of fire safety, almost all public, industrial and administrative buildings and structures are equipped with fire safety systems. The security and fire alarm system, together with organizational measures, helps to quickly localize the source of fire, thereby saving lives and property. First, consider what tasks the OPS system solves:

1. fast detection of the place of ignition;
2. prompt notification of people about the danger that has arisen;
3. transmission of control signals to automatic fire extinguishing and smoke removal systems;
4. transmission of relevant messages to interested persons or services.

To date, OPS systems are divided into the following types:

1. Conventional (traditional) fire alarm system;
2. Address-threshold fire alarm system;
3. Analog addressable fire alarm system.

Address-analogue systems are divided according to the type of installation: wired and wireless. Wired systems are considered more reliable, because. do not depend on the influence of frequency interference of the transmitted signal from detectors and control devices.

Structural diagram of the fire alarm system using the equipment of the NVP "Bolid" as an example:

Fire alarm system

Let us consider in more detail each type of fire alarm. Let's start with the conventional (traditional) system.

Often non-address systems are used in small and medium-sized facilities. Due to the small amount of equipment, these systems are relatively inexpensive. The devices use a modern digital signal processing algorithm, which can significantly increase the reliability of the received signals from the detectors, and as a result, the probability of false alarms is reduced, but it must be taken into account that detectors operating in a non-address system do not provide an adequate level of reliability. The principle of operation is approximately the following: control panels determine the state of the alarm loop by two static states: “normal” and “fire”. When the detector generates a "Fire" notification, the current in the alarm loop changes.

When the reliability criterion for issuing an alarm message at an object comes to the fore, it is necessary to install an address-threshold or address-analogue system. At small and medium-sized objects, it is advisable to use threshold-address systems that combine the advantages of analog-address and traditional systems. The main difference between the address-threshold alarm system and the non-address one is in the topology of the circuit construction and the algorithm for polling the detectors. The control panel polls the connected fire detectors cyclically to ascertain their status. At the same time, each detector in the loop has its own unique address and can already be in several static states: “normal”, “fire”, “malfunction”, “attention”, “dusty”, etc. In this case, the detector independently makes a decision on the transition to another state. Unlike traditional systems, such a polling algorithm allows you to accurately determine the location of the fire to the detector.

To date, addressable analog systems are the most progressive and reliable. They do not have the disadvantages inherent in non-address and address-threshold systems. Most often, these systems are used in medium and large objects. The advantages of installing analog addressable systems are obvious: free topology plus the ability to determine the location of a line break (this is essential for long cable routes). In such systems, the decision on the state of the protected object is made by the control device, and not by the detector. In the configuration of the control panel, for each connected addressable device, the response thresholds ("Normal", "Attention" and "Fire") are set. This allows you to clearly form the operating modes of the fire alarm for a particular room. The monitoring device constantly polls the connected detectors and analyzes the obtained values, comparing them with the threshold values set in its configuration. It is desirable to make the topology of the address line ring. This is necessary so that in the event of a break in the cable route with detectors, the entire system retains its operability, since it simply breaks up into two radial independent loops. All these advantages of the analog addressable system provide early fire detection and reduce false alarms.

Separately, we note the radio channel systems of the OPS. These systems or its elements are in demand at those facilities where it is not possible to lay wires. Often, the security and fire alarm system existing at the facility is supplemented in the future with radio channel elements of the system. Recently, there has been a sharp jump in the level of development of the element base responsible for transmitting and receiving signals over a radio channel. Reliability and service life of devices of radio channel systems meet modern requirements for reliability and noise immunity. Installation of radio channel signaling requires significantly less material costs due to the absence of the need to lay cable routes. On the other hand, the cost of the radio channel devices themselves is higher than their wired counterparts, and the system commissioning procedure is more laborious due to the impossibility of accurately calculating the interference situation at the facility and the non-linear dependence of the signal level in the radio channel on the parameters of the supporting structures of the building. Also, the cost of maintaining a radio channel system is more expensive, due to the need for periodic replacement of batteries.

To prevent unauthorized entry and identify sources of fire, fire alarm equipment is installed at the facilities, which is a whole range of special technical means. Thanks to the integration of this complex into the life support system of the facility, it becomes possible to form a multifunctional network that combines access systems, fire extinguishing systems and all kinds of engineering communications. This approach allows you to automate the process of operation and protection of the object.

Functionality

When combining a fire and security alarm system, a multifunctional complex is obtained, which simultaneously protects the object from fire and detects cases of unauthorized entry.

Implementation of integration is carried out at the level of management and centralized monitoring. All systems of the complex are used centrally, but they function and are managed separately. Simply put, they are autonomous in the overall system.

The fire alarm performs the following functions:

Early fire detection.
Sending an alarm to the relevant services.
Informing people at the facility about what happened.
Ensuring safe evacuation.

Security alarm features:

Prevention of unauthorized entry.
Organization of an access system (employees can only enter certain areas).
Fixing the place and time of penetration.
Determination of the method of entry.

Fire alarm equipment

The list of fire alarm devices used depends on the functionality of the system and the tasks that will be solved with its help.

Equipment used to provide fire alarms can be divided into 5 categories:

♦Equipment enabling centralized alarm control. This category includes a central computer with the necessary software. It is with its help that automation of alarm management is carried out. The security and fire panel can be used in those cases when installation of the fire alarm system of the simplified configuration is required.

♦To monitor certain areas of the object, touch sensors are used. The essence of their work is to control certain parameters, in the event of a change in which an immediate reaction occurs. This category includes all kinds of detectors and sensors.

♦Executive equipment. Necessary to activate means of protection against fire or unauthorized entry. These devices are responsible for transmitting an alarm signal to the appropriate services and alerting people on the site of a potential hazard.

♦Cable equipment. It is used to connect all the above devices into a single complex. It is thanks to the wired equipment that the switching of devices, the transmission of control impulses and alarm signals is carried out.

Purpose of fire alarm devices

The fire system includes almost the same devices as the burglar alarm. The difference lies only in the actuators and sensors used. The functionality of each individual device will be presented below.

Control panel

It is a small computer on which special software is installed. It controls the operation of each device in the system. The control panel allows you to configure the system and manage its operation. Also, its functions include remote monitoring of the health of all connected devices.

Control panel

With the help of this special device, data is collected from alarm sensors, followed by their analysis. These modules are installed separately or are part of the control panel. In systems with a simplified configuration, the control panel can be used as a control panel.

Sensors

This category of devices includes detectors and sensors of various types that control the necessary parameters in their area. The sensor will work only if the value of one of these parameters is out of range.

At the moment, a huge number of various sensors are presented on the market, which allow people to be warned of danger in a timely manner and, using the receiving and control module, send the corresponding signal to the control panel.

There are several types of sensors used in automatic fire alarms:

Smoke detectors. Evaluate the smoke content of the room that occurs in the event of a fire.
Thermal sensors. Capture changes in ambient temperature due to fire.
Flame sensors. They give a signal when an open fire is detected.
Gas sensors. They are triggered in the event of a change in the concentration of a certain gas in the composition of the air.
Hand sensors. Used by facility personnel to turn on the fire extinguishing system when a fire is detected.
multisensor sensors. Their peculiarity lies in the fact that they are able to analyze 4 signs of a fire at once.

All sensors used in fire alarm systems differ in their operating parameters (response speed, sensitivity, etc.). The sensor model should be chosen based on the tasks that need to be solved at the facility.

Types of sensors used in burglar alarm systems:

Motion sensors. Determine the presence of movement in a certain area.
Sensors for opening windows and doors. Allows you to detect cases of opening windows or doors.
vibration sensors. They will give a signal if attempts are made to collapse the structural elements of the object, including walls.
acoustic sensors. Activated when glass is broken.

Also, security systems can be equipped with devices that control the parameters of the object's environment. These include sensors for monitoring the leakage of water, gas, increasing humidity and temperature.

Installation of equipment

It is very important to correctly install the alarm. The degree of protection of the object depends on this. To achieve the maximum level of protection, it is necessary to develop a configuration and plan for the security and fire system before starting the installation of equipment.

At this stage, the required number of detectors is calculated and the places for their installation are determined. The engineer needs to take into account the response speed of the sensors, their sensitivity and coverage area.

The sensors must be installed in such a way as to overlap each other's sensitive areas. This approach will eliminate the presence of "blind" zones. Simply put, absolutely the entire protected area should be under control. It is also very important to avoid external factors affecting the sensors, which include thermal and ultraviolet radiation, as well as all kinds of mechanical stresses.

Wired lines are used to interconnect fire and security alarm devices. Wireless devices are used to facilitate the installation process of the system. In this case, the signal to the central panel from the sensors will be transmitted not by wire, but by radio channels.

Upon completion of the installation, it is necessary to make sure that all sensors, control equipment and the central panel are operational.

Fire alarm "Caesar Satellite"

No matter how new the repair in your house is, no matter how much the office rent costs, even if you are sure that the premises have high-quality wiring, no one is insured against spontaneous combustion or accident. The only way to eliminate the emergency consequences of a short circuit or fire is to install a fire alarm with console protection.

How a fire alarm works: installation and installation

A fire protection system is not an ordinary alarm that reacts to the presence of smoke in a room. This is a complex project that consists of several mandatory steps:

Design. Our experts evaluate the features of the premises, access to communications, potential ways of spreading fire and smoke in order to respond to the threat as soon as possible and minimize the consequences of fire, as well as prevent any damage. For each object in Moscow, a fire alarm system is installed taking into account the established safety standards and GOSTs.
Implementation. In order not to distract you from everyday worries and not change your schedule, all work on the installation of sensors and signal transmission systems is carried out in a short time. Most often, our specialists hand over to the customer a room with a functioning security and fire alarm within 3 hours after arriving at the facility. As a result, sensors have been installed throughout the building that respond to smoke and sound signals to warn of the need to evacuate people from the premises.
Service. The fire alarm is active 24 hours a day. All this time, the dispatcher is watching her, and in the event of an emergency situation, a signal about a potential danger will be sent to the control panel. The regulated response time to a threat is a few seconds. This is enough for the operator to report the threat to the services of the Ministry of Internal Affairs and the Ministry of Emergency Situations, as well as to send a rapid response team to the scene. A trained crew, even before the arrival of the Ministry of Emergency Situations, begins to eliminate the causes of fire and evacuate valuables.
