Security and fire alarm (FSA). Security and fire alarm equipment What is included in the fire alarm system
OPS is a complex of sensors and devices that differ in performance, weight, functions and dimensions. Smoke detectors, motion detectors, temperature detectors and others are highlighted. When the alarm is triggered, the device notifies by SMS and sends a signal to the police station. A similar notification occurs in the event of a fire.
The security and fire alarm system is a complex complex consisting of technical equipment that prohibits the entry of unauthorized persons into the territory.
Means of security and fire alarm systems are divided into three kinds: conventional, address and analog-address:
- The conventional system is usually used in small facilities where a large number of sensors are not required;
- Address and analog address systems are used in large areas where it is necessary to use a large number of switched equipment. This system uses a loopback loop that is less likely to damage communication lines. It is worth clarifying that conventional and analog-address signaling systems are switched among themselves, even if the systems are produced by different manufacturers. To do this, you must use the control panel.
The control panel is responsible for alerting and controlling the fire and security alarms using special interfaces, an alphanumeric keypad, as well as light and sound alarms. In small facilities, control panels are used that use a set of relay outputs. At large and medium-sized objects, control panels with network technologies are used, which allow you to exchange information with external interfaces, as well as receive information via an Ethernet network or by using a telephone line.
Also, the security and fire alarm equipment includes peripheral devices, these include all types of devices that are connected to the control panel.
Common peripheral devices:
- - the device is installed in places where it is necessary to warn of the danger of fire or alarm by means of a sound signal;
- - works according to the same system as the sound system, and is installed in places where it is necessary to warn of the danger of fire or alarm by means of a light signal. As a rule, light and sound annunciators are combined in one place;
- used to control the fire and security alarm complex;
- Isolation module for possible short circuits - this device is responsible for the correct operation of the ring loops in the event of a short circuit.

In the modern world, reliability and safety have long been synonymous with peace, which is why burglar alarms are the best solution for protecting commercial and residential premises. Security fire alarm systems are a whole integrated complex of fire and security systems that prevent unwanted entry into the room and prevent the occurrence of fires.
When faced with a choice between an integrated security fire alarm and separate systems, it is better to immediately pay attention to the security fire alarm complex. It is not only much more profitable to maintain, but also more convenient to operate. Convenience of control lies in the fact that the equipment of security fire systems in the control is displayed on one panel, which allows you to simultaneously monitor a number of violations at once: fire, unwanted entry, etc.
Fire alarm systems are 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 mean a combination of technical elements of a fire alarm to trigger a fire alarm, and it can be either automatic or manual. The signal goes to the control panel from detectors located in rooms requiring protection. Addressable fire alarm systems are 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 workable security and fire protection system. The convenience of a radio channel system mainly lies in the fact that it can be placed even on complex objects with several buildings or an unusual layout. The signal travels over radio waves, which avoids dependence on the integrity of the cables and the busyness of telephone lines.
GSM alarm
GSM system is a combination of gsm alarm devices and fire and burglar alarms. Efficiency and instant notification are the main advantages of GSM Monitoring. Prompt notification and quick response can reduce damage and risk to a minimum.

Security and fire alarm systems(OPS) is something that no real estate object can do without. In Russia (as in other countries) there is a national GOST, which regulates the installation and maintenance of OPS. Its observance is monitored by the relevant services, applying tough measures to violators, which is not surprising - after all, a fire that has arisen and is not extinguished in a timely manner threatens not only property, but the health and lives of people.
That is why it is so important to know:
What is OPS;
Varieties of security and fire alarm systems;
Their advantages and disadvantages;
What are the main components they consist of;
What functions do they perform;
What to be guided by when choosing an OPS.
Aside from purely technical terms, a security and fire alarm is a combination of sensors, detectors, control and monitoring devices, as well as auxiliary equipment, designed to ensure the fire safety of an object. The connection of the elements of the complex into a single whole can be wired or wireless, depending on the specific situation and the wishes of the customer - but this does not affect the tasks assigned to the FSA.
● Timely detection of the fire source.
● Prompt fire notification of people and fire services.
● Prevention of false positives.
● Turning on the automatic fire extinguishing system.
● Regulation of air flow (from the air conditioning system, ventilation, etc.).
● Removal of smoke.
● Emergency control of building elements (doors, elevators, etc.).
Sensors(smoke, heat, flame, gas, etc.) fix the presence of a fire and transmit a signal to the receiving-control and control panels, which process the signal to prevent false alarms and, when the fire is confirmed, turn on the sirens, the fire extinguishing system and perform other programmed actions.
There are several types of FSA, which differ in the type of sensor connection and other parameters. Let's consider some common types of OPS.
Threshold or unaddressed FSA
The sensors are connected to common loops without specifying the number and location. In the event of an alarm from a sensor, the station will only know the number of the loop to which the triggered sensor is connected. Therefore, such OPS are installed only on small-sized objects, where there are no more than 30 rooms.
The advantage of such OPS is budget. Disadvantages - a rather large number of false alarms, the difficulty of finding a fire source (especially in smoky rooms), expensive installation due to the high consumption of mounting materials and sensors (at least two per room).
Address FSA
Sensors are connected to loops with an exchange protocol, therefore information about each triggered sensor is visible at the station, i.e. there is an exact indication of the place of fire. This increases the responsiveness, but ... other disadvantages of threshold NSOs remain (it should also be taken into account that targeted NSOs are more expensive than threshold ones). Such OPS are also installed on small-sized objects.
Analogue addressable FSA
If the first two types of OPS we considered were characterized by a low cost of equipment and a rather high cost of installation, then with analogue OPS everything is different: the high cost of equipment and low-cost installation. As a rule, such OPS are installed on large objects (shopping and office centers, etc.), but they can also be installed on a small object (if the price issue is not relevant for the owner).
If in the address and threshold fire alarm systems the detector made the decision about the presence of fire, then in the analogue ones it was the control system that monitors the state of the sensors and makes a decision based on the change in parameters. Such systems are among the most modern and reliable, since the level of reliability of the alarm signal is very high. In addition, the notification of the relevant services is also carried out promptly.
The advantages of analogue addressable fire alarm systems include:
Reliability of the system even in the event of a loop break;
There are algorithms that prevent false alarms (the sensitivity of the sensors is automatically checked, there is a day / night mode, etc.);
It is possible to expand the system without serious material costs;
A large number of additional and service options that simplify the work with the system;
Ease of interaction with automatic building systems (elevators, ventilation, etc.);
Ease and low cost of installation and service.
The disadvantage is the need to use a twisted pair for installation, with a limitation in length.
Combined OPS
The control and monitoring equipment in such FSA has a modular structure, and there are modules for analogue addressing and for connecting one- and two-port loops.
GI systems company carries out the implementation and installation security and fire devices... Premises of any size - offices, country houses, industrial facilities - will be protected by reliable equipment.
A properly designed system helps to anticipate various emergencies at a guarded facility, effectively protecting property and working personnel. OPS devices make it possible to track the leakage of gas, water, the occurrence of a fire source. The pre-installed program automatically issues a command to the security and fire equipment to perform an action (turn on the siren, start the water supply, turn off the tap, etc.).
A special GSM-system will duplicate the alarm signal to a mobile phone, this notification option allows you to remotely control the situation. When traveling, business trip, the owner of the property will always be confident in the safety of the property. The convenience of using the GSM notification system has long been appreciated by the owners of private households and commercial objects.
Using the services of competent specialists, you gain confidence in the trouble-free, reliable operation of the fire alarm devices. Autonomous devices can be used to guard the facility, their purpose is to scare off intruders, signal the penetration with a powerful sound signal. Stand-alone detectors are designed for various tasks. The information is captured by motion sensors, window devices, acoustic fixtures, etc., and then sent to the base unit.
