Fire alarm (PS) This is a complex of technical means, the purpose of which to detect fire, smoke or fire and to notice the person in a timely manner. The main task of salvation of people's life, minimizing damage caused and preserving property.
It may consist of the following elements:
By the method of control over the loops, the fire alarm is distributed to the following types:
It is often called traditional. The principle of operation of this type is based on a change in resistance in the loop of fire alarm systems. Sensors can only be in two physical states. "norm"I. "fire" In the event of fixing the factor of the fire, the sensor changes its internal resistance and the receiving and control device outputs the alarm along the loop in which this sensor is installed. It is not always visually to determine the place of work, because In the threshold systems on one plume, an average of 10-20 fire detectors are installed.
To determine the SC malfunction (and not the state of the sensors), the terminal resistor is used. It is always installed at the end of the loop. When using fire tactics "Traveling PS for two detectors", to receive a signal "Attention" or "Fire probability" In each sensor, the adding resistance is installed. This allows you to apply automatic fire extinguishing systems at the facility and eliminating possible false alarms and damage. Automation of fire extinguishing is launched only in the case of the simultaneous work of two or more detectors.
PPKP "Granit-5"
The following PPCP can be attributed to the threshold type:
The advantages of traditional systems include ease of installation and low cost of equipment. The most significant drawbacks are the inconvenience of the fire alarm service and the high probability of false alarms (resistance may vary from many factors, sensors cannot transmit dust information), reduce the number of which you can only use another type of PS and equipment.
A more perfect system is capable of automatic mode to periodically check the state of the sensors. In contrast to the threshold alarm, the principle of operation lies in another sensor survey algorithm. Each detector is assigned its own unique address, which allows the receiving-control device to distinguish them and understand the specific reason and the location of the malfunction.
The SP5.13130 \u200b\u200brules set allows you to install only one address detector provided that:
Sensors in the address-threshold alarm can already be several physical states - "norm", "fire", "Malfunction", "Attention", "Dustiness" And others. In this case, the sensor independently goes into a different state, which allows you to determine the location or ignition with an accuracy of the detector.
PPKP "DOZOR-1M"
The following PPKP can be attributed to the address and threshold type of fire alarm:
The most progressive type of fire alarm. It has the same functionality as address-threshold systems, but differs in the method of processing signals from sensors. Decision on the transition to mode "fire" Or any other state takes the control panel, and not a detector. This allows you to configure fire alarm operation for external factors. The PPCP simultaneously controls the status of the parameters of the installed devices and analyzes the obtained values, which makes it possible to significantly reduce the likelihood of false alarms.
In addition, such systems have no challenging advantage - the ability to apply any topology of the address line - tire, ring and star. For example, in the case of a ring lines break, it will split into two independent wired loops that will fully retain their performance. In a star type lines, you can use special short-circuit insulators that determine the place of the lines of the line or its closure.
Very comfortable such systems in service, because You can detect real-time detectors that require purge or replacement.
The following PPCP can be attributed to the address and analog type of fire alarm.
Scheme address-analog system Fire alarm based on PPKP C2000-KDL
During the choice of the designers, all the requirements of the customer's technical task are taken into account and pay attention to the reliability of functioning, the cost mounting work and regulatory requirements. When the reliability criterion for a simpler system begins to fall, the designers switch to the use of a higher level.
Radio channels are used in cases where the cable laying becomes economically unprofitable. But this option requires more tools for maintenance and maintaining devices in working condition by periodic replacement of batteries.
Types and types of fire alarm systems, as well as their classification is presented in GOST R 53325-2012 "Fire technique. Fire automation technical means. General technical requirements and test methods. "
Address and non-educational systems We have already considered higher. Here you can add that the first allow you to install non-educational fire detectors, through special extenders. One address can be connected to eight sensors.
According to the transmitted information from the PPCP to the sensors are divided into:
According to the general information container, i.e. The total number of connected devices and loops are divided into devices:
According to informative, otherwise, according to the possible number of issued notices (fire, malfunction, dustiness and other) are divided into devices:
In addition to these parameters, the system is classified by:
The main task of the alert and evacuation management system (SOUD) is the timely alert of people about the fire in order to ensure safety and operational evacuation from the smokers and buildings in a safe area. According to FZ-123 "Technical Regulations on Fire Safety Requirements" and SP 3.13130.2009, it is divided into five types.
On the majority of small and medium-sized fire safety standards, you must install the first and second type of alert.
At the same time, for the first type, the mandatory presence of a sound bearing is siren. For the second type, the Light Tablo "Exit" is added. Fire alert must work simultaneously in all rooms with a permanent or temporary stay of people.
These types are related to automated systemsThe launch of the alert is fully assigned automation, and the role of a person in managing the system is minimized.
For the third, fourth and fifth type of SUE, the main method of warning is speech. Pre-developed and recorded texts are transmitted, which allow evacuation as efficient as possible.
In the 3rd type Additionally, the "Exit" light pointers is used and the sequence of alert is regulated - first service personnel, and then all the others on a specially designed order.
In the 4th type There is a requirement for the availability of communication with the dispatching inside the alert zone, as well as additional light pointers of the direction of movement. Fifth typeThis includes everything that is listed in the first four, plus this is added to this requirement on the availability of the inclusion of light pointers for each evacuation zone, a full automation of the control system control and the organization of many evacuation paths from each alert zone is provided.

In the modern world, reliability and safety have long been synonymous with calm, which is why the fire alarm system is stopped - this is the best decision Protection of commercial and residential premises. Fire alarm systems are a whole combined complex of firefighters and security systems that prevent unwanted penetration into the premises and warning the occurrence of fires.
Standing in front of the choice between the integrated fire alarm system and separately taken systems, it is better to immediately pay attention towards the complex of fire alarm system. It is not only much more profitable in service, but also more convenient to operate. The convenience of control is that the equipment of fire systems in management is excreted for one remote, which allows you to simultaneously monitor immediately for a number of violations: ignition, unwanted penetration, etc.
Fire alarm systems They are divided into several options, whose choice is purely individual. It is worth noting that when choosing a system of this or that system should take into account the specifics of installation and maintenance. It is these details that will help you decide on the choice and choose an option that meets all your requirements.
Address Systems Fire Alarm
Under the address systems of the fire alarm, the combination of the technical elements of the fire alarm is understood to turn on the fire signal, and it can be both automatic and manual. The signal goes to the control panel from detectors, which are placed in rooms requiring protection. The addressing system of fire alarms differ relatively low cost and make it possible to quickly respond to emergencies, which makes it possible to avoid serious problems.
Radio channel security systems
Radio channel security systems are devices aimed at creating a working security system and fire protection. The convenience of the radio channel system mainly is that it is possible to place it even on complex objects that have several buildings or unusual layout. The signal comes along radio waves, which avoids dependence on the integrity of cables and employment of telephone lines.
GSM alarm
GSM system represents a totality of the device gSM alarm and firefighters and security detectors. Operation and instant notification is the main advantage of GSM monitoring. Timely alert and quick response can reduce damage and risks to a minimum.
Security and fire equipment
If you decide to buy a fire alarm guard, it is worth paying special attention to the equipment of the fire systems. The complex of the OPS includes: receiving control devices to which all information is directly coming; Detectors security; Fire detectors, technological detectors, alarm and more.
Progress does not stand still, which is why when choosing equipment, it is better to turn to qualified professionals who can easily tell you about the most modern novelties and development.

Systems fire alarm (OPS) is something, without anything, no real estate object can do. In Russia (as in other countries) there is a national GOST, which regulates the installation and service maintenance OPS. It is followed by the relevant services, applying tough measures to the violators, which is not surprising - after all, the fire that occurred and not extended in a timely manner threatens not only the property, but the health and lives of people.
That is why it is so important to know:
What is the OPS;
Varieties of security and fire alarm systems;
Their advantages and disadvantages;
From which major components they consist;
What functions are performed;
What to be guided when choosing an ops.
If you distract from purely technical terms, the fire alarm system is a combination of sensors, detectors, receiving and control devices, as well as auxiliary equipmentdesigned to provide fire safety object. The connection of the elements of the complex into one can be wired or wireless depending on specific situation And the wishes of the customer - but this does not affect the task set before the OPS.
● Timely detection of fire focus.
● Operational alert about the fire of people and fire services.
● Prevent false positives.
● Enabling automatic fire extinguishing system.
● Adjusting air flow (from the air conditioning, ventilation, etc.).
● Deleting smoke.
● Emergency management of building elements (doors, elevators, etc.).
Sensors (smoke, thermal, flame, gas, etc.) fix the presence of ignition and transmit a signal to the receiving and control panel, which process the signal to prevent false response and when confirming the ignition, include firing, fire extinguishing system and perform other programmed steps.
There are several varieties of OPS, differing from the type of sensor connection and other parameters. Consider some common types of OPS.
Thresholds or chaasadres
Sensors are connected to common loops without specifying the number and location. When alarm signal from the sensor, only the loop number will be known to the station to which the sensor has been connected. Therefore, such OPSs are installed only on small objects in areas where no more than 30 rooms.
The advantage of such OPS is budget. Disadvantages are a fairly large number of false positives, the complexity of finding a focus of fire (especially in the smoked rooms), expensive installation due to a large consumption of mounting materials and sensors (at least two per room).
Addressible ops
Sensors are connected to loops with the exchange protocol, so the station shows information about each successful sensor, i.e. There is an accurate indication of the place of fire. This increases response efficiency, but ... other shortcomings of threshold OPS remain (should still be taken into account that the targeted OPS is more expensive thresholds). Such OPS is also installed on small objects.
Address and analog OPS
If the first two OPS species considered by us were characterized by a low cost of equipment and quite high - installation, then with address and analog OPS is different: high cost of equipment and budget installation. As a rule, such an OPS put on large objects (trade and office centers, etc.), but they can be installed on a small object (if the price is not relevant to the owner).
If a detector has received a detector in the address and thresholds of the OPS, then in the address-analog control system, which monitors the state of the sensors and makes a decision on the basis of changes in the parameters. Such systems are one of the most modern and reliable, since the level of reliability of the alarm is very high. In addition, the alert of the relevant services is also performed promptly.
The advantages of address-analog OPS include:
The reliability of the system is even in the case of a loop cliff;
There are algorithms that prevent false responses (sensor sensitivity is automatically checked, there is a day / night mode, etc.);
It is possible to build a system without serious material costs;
A large number of additional and service options that simplify work with the system;
Easy to interact S. automatic systems buildings (elevators, ventilation, etc.);
Easy and low cost of mounting and service.
The disadvantage is the need to use a vitu pair to mount, with a length limit.
Combined ops
The receiving and control equipment in such OPS has a modular structure, and the modules are also address-analog, and for connecting single and two-port loops.
To prevent unauthorized penetration and detection of foci of ignition at objects, install equipment for security and fire alarm, which is a whole range of special technical means. Thanks to the integration of this complex in the system of providing the life of the object, it is possible to form a multifunctional network that combines access, fire extinguishing systems and all kinds of engineering communications. This approach allows you to automate the process of operation and protect the object.
When combining a fire and security system alarm, a multifunctional complex is obtained, which simultaneously protects the facility from the fire and identifies cases of unauthorized penetration.
The implementation of integration is carried out at the control and centralized monitoring level. All systems of the complex are used centrally, however, and are operated separately. Simply put, they are autonomous in the overall system.
Fire alarm performs the following functions:
Security alarm capabilities:
The list of used fire alarm devices depends on the functionality of the system and tasks that will be solved with its help.
Equipment used to ensure fire alarm can be divided into 5 categories:
♦ Equipment that allows you to perform centralized signaling management. This category includes a central computer with the necessary software. It is with its help that an alarm management is automated. The firebar can be used in cases where the fire alarm is required to install a simplified configuration.
♦ To track specific object zones, touch sensors are used. The essence of their work is to control certain parameters, in the case of which the immediate response occurs. This category includes all kinds of detectors and sensors.
♦ Executive equipment. It is necessary to activate the means of protection against fire or unauthorized penetration. These devices are responsible for transmitting alarm to appropriate services and alerts located at the facility of people about potential danger.
♦ Cable equipment. Used to connect all the above devices into a single complex. It is thanks to the wired equipment that the instruments are switched out, the transfer of control pulses and anxiety signals.
The fire fighting system includes almost the same devices as security alarms. The difference lies only in the executive devices and sensors used. Below will be presented functionality Each single device.
Control panel
It is a small computer on which special software is installed. With it, it is managed by the work of each system device. The control panel allows you to configure the system and manage it. It also includes remote monitoring of the performance of all connected devices.
Receiving and control device
With this special device, data is collected from the signaling sensors, followed by their analysis. These modules are set separately or are part of the control panel. In systems with a simplified configuration, the receiving and control module can be used as a control panel.
Sensory
This category of devices includes detectors and sensors. different typescontrolling the necessary parameters in the accountable zone. The sensor will work only if the value of one of these parameters will be released for the permissible boundaries.
IN currently The market presents a huge number of all kinds of sensors, which allow you to promptly warn people about the danger and use the receiving and control module to send the corresponding signal to the control panel.
There are several types of sensors used in automatic fire alarm:
All sensors used in fire alarm systems differ in the operating parameters (triggering speed, sensitivity, etc.). The sensor model should be selected based on the tasks that need to be solved on the object.
Types of sensors used in security alarm systems:
Also, security systems can be equipped with appliances that control the parameters of the object environment. These include water leakage control sensors, gas, increasing humidity and temperature.
It is very important to correctly perform an alarm installation. From this depends on the degree of protection of the object. To achieve the maximum level of protection, before starting the installation of the equipment, develop a configuration and plan of the security and fire system.
At this stage, the calculation of the required number of detectors is calculated and the places of their installation are determined. The engineer needs to take into account the speed of triggering the sensors, their sensitivity and the coating zone.
Sensors must be installed in such a way as to overlapping the sensitive zones of each other. This approach will eliminate the presence of "blind" zones. Simply put, under control there should be absolutely all protected area. It is also very important to avoid exposure to the sensors of external factors to which thermal and ultraviolet radiation include, as well as all sorts of mechanical loads.
Wired highways are used to connect to the fire and security alarm devices. Wireless appliances are used to facilitate the installation of the system. In this case, the signal to the central panel from the sensors will be transmitted not by wires, but using radio channels.
Upon completion, you need to make sure that all sensors, receiving and control equipment and the central panel are performed.
Training video on the installation of alarm.
If you want your guard and fire complex to work properly for many years and performed functions assigned to it, the installation of equipment should be entrusted to qualified specialists.
Today, its services for the preparation and implementation of security and fire alarm projects provide many companies. Some of them are additionally engaged and selling the necessary equipment, as well as maintenance and setting systems. Choose correctly necessary equipment And it is unmistakable to fulfill its installation for only a professional. Fire and security alarm is a pledge of the safety of the life and material values \u200b\u200bof the person.
