Requirements for security and fire alarm systems. What are the requirements for security and fire alarms?

Purpose of systems burglar alarm is to detect the appearance of signs of an intruder at a protected facility and submit an alarm notification to take measures to apprehend the intruder.
The purpose of alarm systems (ALS) is to detect danger at a protected facility and provide an alarm notification to take measures to eliminate the danger.
The structure of the security and alarm system is determined depending on:
- operating mode of the facility;
- the procedure for conducting transactions with valuables;
- features of the location of premises with valuables inside the building;
- selection of the number of protected zones, security lines, alarm loops (AL).
The classification of protected objects is made in accordance with Chapter. 3 RD 78.36.003-2002 "Engineering and technical strength. Technical means of security. Requirements and design standards for protecting objects from criminal attacks."
Depending on the significance and concentration of material, artistic, historical, cultural and religious values located on the site, the consequences of possible criminal attacks on them, all objects, their premises and territories are divided into two groups (categories): A and B. Due to the large variety of heterogeneous objects in each group, they are further divided into two subgroups each: AI and All, BI and BII.
The security alarm system must:
- detect sabotage actions of the intruder and issue a notification of unauthorized access;
- issue a fault notification upon failure technical means security alarm;
- maintain good condition when exposed to influencing factors environment;
- restore operational state after exposure to hazardous environmental factors;
- be resistant to any damage to any of its parts established in the standards for systems of a particular type and not cause other damage in the system or lead to indirect danger outside it;
- maintain an operational state when the network power supply or other main power source is turned off during the time of power interruption. Opening hours from backup source The power supply must correspond to that specified in GOST 26342-84.
The security alarm system should not give false alarms when switching mains and reserve power sources or other types from one to another.
The security alarm system must be protected from unauthorized access to software control by code that must meet the requirements of standards for systems of a particular type.

To protect the personnel of facilities where goods of group A are located, work time, against criminal attacks, an alarm system is installed (buttons, pedals, etc.), which is intended to transmit alarm signals to the duty units of internal affairs bodies (police departments) to take timely measures in the event of a robbery attack on an object.
Features of the installation of the alarm system are regulated by Chapter 6 of the Recommendations to RD 78.36.006-2005.
STS elements must have clear, indelible and indelible markings indicating the name of the company or its trademark and model number.
If the design allows, then the elements of the STS must be clearly and indelibly or indelibly marked with the following additional information:
- serial number;
- date of manufacture (a code may be used);
- values of electrical quantities, for example values of rated voltages, current and frequency.
If the design does not allow this, then this information must be given in the operating documentation or on the packaging.
Wires and connectors must be numbered, colored, or otherwise identified.
The product must be supplied with instructions detailing how to correct installation, if this is not clear from the design of the product. Also, the product must be accompanied by operational documentation in accordance with GOST 2.601-2006, and, if necessary, repair documentation in accordance with GOST 2.602-95.
For STS, maintenance of a form must be provided. The forms of entries in the form must be specified in the regulatory and technical document for operation and maintenance systems or in standards for STS of a specific type (clause 9.3 of GOST R 50775-95 (IEC 60839-1-1:1988).
Design, preparation and execution of work on equipment for trade and Catering security alarm systems must be carried out in accordance with the following regulatory and technical documents:
- RD 78.36.003-2002 "Engineering and technical strength. Technical means of security. Requirements and design standards for protecting objects from criminal attacks";

RD 78.36.003-2002 provides requirements for security alarm systems.

Protection of the perimeter of the territory and open areas.

Technical means of perimeter security alarms should be selected depending on the type of alleged threat to the facility, the interference situation, the terrain, the length and technical strength of the perimeter, the type of fencing, the presence of roads along the perimeter, the exclusion zone, its width.

The security alarm system for the perimeter of an object is designed, as a rule, to be single-line.

To strengthen security, determine the direction of movement of the intruder, and block vulnerable spots, multi-directional security should be used.

Technical means of perimeter security alarm can be placed on the fence, buildings, structures, structures or in the exclusion zone. Security detectors must be installed on walls, special poles or racks that ensure the absence of vibrations.

Medium and large capacity control panels (concentrators), SPI, automated notification transmission systems (ASPI) and radio notification transmission systems (RSPI) can be used as internal security panels. Internal security consoles can operate both with direct personnel on duty around the clock, and autonomously in the “Self-Security” mode.

Installation security detectors along the top of the fence should only be done if the fence has a height of at least 2 m.

At the checkpoint and in the security room, technical devices for graphically displaying the protected perimeter (computer, light board with a mnemonic diagram of the protected perimeter and other devices) should be installed.

All equipment included in the perimeter security alarm system must be tamper-evident.

Open areas with material assets on the territory of the facility must have a warning fence and be equipped with volumetric, surface or linear detectors different operating principles.

Protection of buildings, premises, individual items. All premises with permanent or temporary storage of material assets, as well as all vulnerable areas of the building (windows, doors, hatches, ventilation shafts, ducts, etc.), through which unauthorized entry into the premises of the facility is possible, must be equipped with technical security alarm systems.

Objects of subgroups AI, AII and BII are equipped with a multi-terminal security alarm system, objects of subgroup BI are equipped with a single-terminal alarm system.

The first line of the security alarm, depending on the type of perceived threats to the facility, is to block:

wooden entrance doors, loading and unloading hatches, gates - for “opening” and “destruction” (“break”);

glazed structures - for “opening” and “destruction” (“breaking”) of glass;

metal doors, gates - for “opening” and “destruction”,

walls, ceilings and partitions that do not meet the requirements of this Guiding Document or behind which the premises of other owners are located, allowing for hidden work for the destruction of a wall - for “destruction” (“break”),

shells of valuable storage facilities - for “destruction” (“break”) and “impact”;

grilles, blinds and other protective structures installed on the outside of the window opening - for “opening” and “destruction”;

ventilation ducts, chimneys, points of input/output of communications with a cross-section of more than 200x200 mm - for “destruction” (“break”);

Protection of site personnel and visitors.

To promptly transmit messages to the central security console (CSC) and/or to the duty department of internal affairs bodies about illegal actions against staff or visitors (for example, robbery, hooliganism, threats), the facility must be equipped with alarm devices (DS): mechanical buttons, radio buttons, radio key fobs, pedals, optical-electronic detectors and other devices.

The alarm system is organized “without the right to switch off.”

Vehicle devices at the site must be installed:

in storage rooms, storerooms, safe rooms;

in weapons and ammunition storage areas;

at cashiers' workplaces;

at the workplaces of personnel performing operations with drugs and psychotropic substances;

in the offices of the organization’s management and chief accountant;

at the main entrance and emergency exits to the building;

at posts and in security premises located in a building, structure, structure and in a protected area;

in corridors, at doors and openings through which valuables are moved;

in a protected area at the central entrance (entrance) and emergency exits (exits);

in other places at the request of the manager (owner) of the facility or on the recommendation of a private security officer.

Hand and foot devices of the vehicle should be placed in places that are, if possible, invisible to visitors. Managers, responsible persons, owners of the facility, together with a representative of the private security unit, determine the locations hidden installation alarm buttons or pedals at employee workplaces.

The management of the facility, security and safety personnel should be equipped with mobile vehicle devices operating via a radio channel (radio buttons or radio key fobs).

Storage locations Money, precious metals, stones and products made from them (desks of cash register workers, metal cabinets or safes, cash registers, display cases, trays, sales counters), in addition, must be equipped with special technical means (traps) that generate alarm signals without participation personnel when an intruder attempts to take possession of valuables. The specified technical means must be included in the alarm loops of the facility.

Organization of transmission of information about alarm activation. The transmission of notifications about the activation of a security alarm from the facility to the central monitoring station can be carried out from a small-capacity control panel, an internal security console or terminal notification transmission system (TPS) devices.

The number of security alarm lines displayed at the central monitoring station by separate numbers is determined by a joint decision of the facility management and the private security unit based on the category of the facility, risk analysis and potential threats to the facility, the capabilities of integration and documentation by the security control panel (internal security console or terminal device) of incoming information, as well as the procedure for organizing the duty of security personnel at the facility.

The minimum required number of security alarm lines output to the central monitoring station from the entire protected facility should be for a subgroup.

BI - one combined boundary (the first is the perimeter);

AI, BII - two combined boundaries (the first is the perimeter and the second is the volume).

In addition, if there are special premises at the facility (subgroup AII, safe rooms, weapons rooms and other premises that require increased protection measures), the security alarm lines of these premises are also subject to output to the central monitoring station.

If the facility has an internal security console with round-the-clock duty of its own security service or private security agency, the following will be displayed on the monitoring station:

one common signal that unites all the boundaries of the facility’s security alarm system, with the exception of the boundaries of the facility’s special premises;

security alarm boundaries (perimeter and volume) special premises.

At the same time, registration of all incoming information of each premises security line on the internal security console must be ensured.

From protected facilities, “auto-dialing” must be carried out to two or more telephone numbers.

To prevent unauthorized persons from accessing detectors, control panels, junction boxes, and other security equipment installed at the facility, measures must be taken to mask them and install them hidden. The terminal block covers of these devices must be sealed (sealed) by an electrician of the security service or an engineer and technical worker of the private security unit, indicating the name and date in the technical documentation of the facility.

Distribution cabinets intended for crossing alarm loops must be locked, sealed and have locking (anti-tamper) buttons connected to separate numbers of the internal security console "without the right to disconnect", and in the absence of an internal security console - to the central monitoring station as part of the alarm system .

When developing a fire alarm project, it is necessary to take into account the requirements of NPB 88-2001 - “Norms and rules for the design of fire extinguishing and alarm installations.”

The building of a medical institution is an administrative structure, therefore its premises, when using automatic fire alarms, should be equipped with smoke fire detectors.

Smoke fire detector is a fire detector that reacts to particles of solid or liquid products of combustion and (or) pyrolysis in the atmosphere.

In each protected room, at least two fire detectors should be installed, since the height of the facility premises does not exceed 3.5 m, the maximum distance between detectors is no more than 9 m, and the distance from the sensor to the wall is no more than 4.5 m.

the main factor in the occurrence of a fire outbreak in initial stage is the appearance of smoke;

There may be people present in the protected premises.

Such detectors must be included in a unified fire alarm system with alarm notifications output to a fire alarm control panel located in the premises of the duty personnel. A fire alarm control panel is a device designed to receive signals from fire detectors, provide power to active fire detectors, and issue information on light and sound annunciators and central monitoring panels, as well as the formation of a starting impulse for launching a fire control device.

Manual fire call point – a device designed to manually activate a signal fire alarm in fire alarm and fire extinguishing systems.

Manual fire call points should be installed on walls and structures at a height of 1.5 m from the ground or floor level in corridors, halls, lobbies, on staircases, and at building exits.

But an effective fire alarm system must necessarily include a system for alerting people about a fire.

Warning and evacuation control system (WEC) is a set of organizational measures and technical means designed to promptly communicate to people information about the occurrence of a fire and (or) the need for and routes of evacuation. The emergency control system must operate for the time necessary to complete the evacuation of people from the building.

The building of the object in question belongs to the second type of SOUE, therefore, it must be equipped with light “Exit” annunciators and sound annunciators (siren or tinted signal).

To ensure clear audibility, the sound signals of the SOUE must provide a sound level of at least 15 dB above the permissible sound level of constant noise in the protected room.

A combined light and sound siren should be placed on the external wall of the building in front of the entrance.

If such means are built-in, the detector must be capable of providing a signal to the alarm system to indicate a decrease in radiation levels.

This signal may take the form of an alarm notification.

6 Test methods

6.1 Test conditions

Tests should be carried out on a hard surface area. The surrounding structures should not influence the distance measurement results by more than 5%.

During testing, the detector must be positioned at the manufacturer's recommended distance from the floor and in accordance with the manufacturer's instructions. If the height of the detector is specified as an interval of values, tests are carried out at the upper and lower values.

Tests must be carried out under normal environmental conditions in accordance with GOST 28198 (according to 5.3).

It is allowed to test detectors at relative air humidity in the range of 40-80%.

6.2 Functional tests

6.2.1 Detection zone boundary

A standard target should be located outside the maximum range of the detector and move towards the detector at a speed of approximately 1 m/s.

The distance from the detector to the standard target at the time it issues an alarm notification is fixed and must be equal to maximum range established in the technical specifications for specific types of detectors, or exceed it by no more than 25%.

The distance from the detector to the standard target at the time it issues an alarm notification must be measured in at least seven directions in each plane (vertical and horizontal). Tests in the vertical plane must be carried out with the detector rotated 90° relative to the radiation axis.

6.2.2 Detector sensitivity to object movement at a constant speed

A standard target should be located in front of the detector at the edge of the detection zone and move towards it at a speed of approximately 1 m/s. The detector must generate an alarm when the target moves within 3 m or 30% of the range, whichever is less, and must not generate an alarm when the target moves within 0.2 m.

A standard target is placed in front of the detector at the edge of the detection zone on its centerline and moves towards the detector at a speed of approximately 1 m/s. The detector must provide an intrusion alert when a standard target moves within 3 m of the start of movement. Moving the target to the detector at a distance of up to 0.2 m should not cause an intrusion notification to be issued.

Tests should be carried out at target speeds of approximately 0.3; 1 and 3 m/s or the highest and lowest speeds of movement, if the technical specifications for specific types of detectors specify a wider range of detectable speeds.

6.2.3 Time to restore the detector to standby mode

A standard target should be located in front of the detector at the edge of the detection zone and move towards it at a speed of approximately 1 m/s. When the detector issues an alarm notification, the distance from the detector to the target is recorded. After this, the standard target returns to the border of the detection zone.

The target is then replaced by some object or person other than the standard target, which moves towards the detector before it issues an alarm notification. After this, the movement stops. No earlier than 10 s from the boundary of the detection zone, the standard target begins to move at a speed of approximately 1 m/s. The distance from the detector to the target at which an alarm notification occurs should not differ from that measured in the first part of the test by more than 10%.

Deviation in the distance from the detector to the target at which a notification about penetration occurred in the second part of the test, from what was measured in the first part of the test, in agreement with the customer, it is allowed to set no more than 15%.

6.2.4 Sensitivity of the detector to object movement during uneven movement

The standard target should be located in front of the detector on the border of the detection zone and move towards it in the following way: move a distance of 1 m for 1 s, then stop for 5 s, after which the cycle repeats. The detector must provide an alarm notification before the target moves 5 m or 50% of the range, whichever is less.

6.2.5 Stability

The test can be carried out at any range of the detector within the limits of its adjustment. During testing, no range adjustment is made.

A standard target should be positioned in front of the detector, behind the mark corresponding to the selected range, and moving towards it at a speed of approximately 1 m/s. The distance from the detector to the target is recorded when it issues an alarm notification.

After at least seven days of operation of the detector in standby mode, the tests are repeated at original conditions. The distance newly recorded during re-testing should not differ from that measured in the first case by more than 10%.

6.2.6 Tamper-proof

If there are means to protect the detector from opening, its housing must be opened using tools usually used for these purposes in such a way as to gain access to the controls and adjustment of the detector.

Before such access is gained, the tamper-evident means must sound an alarm.

The tests should be repeated using a knife or screwdriver in an attempt to bypass the tamper evident features without damaging the detector.

6.2.7 Trunk protection

6.2.8 Detectable speed range

A standard target is placed in front of the detector at the edge of the detection zone on its centerline and moves towards the detector. The detector must provide an intrusion alert when a standard target moves within 3 m of the start of movement.

Tests are carried out when moving a standard target at speeds of 0.3; 1 and 3 m/s.

If the technical specifications for specific types of detectors specify a wider range of detectable speeds, then tests are carried out at the highest and lowest speeds, as well as at a speed of 1 m/s.

6.2.9 Duration of intrusion notification

The test method is established in the technical specifications for specific types of detectors.

6.2.10 Detector readiness time for operation

The test method is established in the technical specifications for specific types of detectors.

The detector supply voltage is set to (15±2)% below its rated value and the detector range is determined in accordance with 6.2.1.

A similar procedure is carried out when the detector supply voltage is increased by (25±2)% relative to its nominal value.

The detector range, measured in both cases, must comply with the requirements of 5.1.2.

6.2.12 Operating frequency

The test method is established in the technical specifications for specific types of detectors.

6.3 Tests for external influences

6.3.1 Test conditions

The following tests (range test) must be carried out before and after exposure to dry heat, cold and sinusoidal vibration (external test conditions are given in IEC 839-2-2*).

Tests can be carried out at any range of the detector within the limits of its adjustment. During testing, the detector range is not adjusted.

A standard target should be positioned in front of the detector, beyond the mark corresponding to the selected range, and move towards it at a speed of approximately 1 m/s. When the detector issues an alarm notification, the distance from the target to the detector is recorded.

The distance from the target to the detector when it issues an alarm notification, recorded after exposure to each external factor, should not differ by more than 10% from the original distance.

Tests may be carried out using simulators if they can be shown to give the same results as the specified test method.

One of the features that characterizes the reliability of a facility’s security is the structure of the installed security alarm system, which is determined by the number of security lines, protected zones, and alarm loops in each line. An object guarded or monitored by a GSO unit is equipped with one or more security lines. As a rule, a multi-site security system consists of 2-3 alarm loops, which are connected to centralized security or surveillance consoles (CSC) using control panels, telephone lines or a radio channel.
The first line is blocked building construction perimeters of objects (window and door openings, hatches, ventilation ducts, thermal inlets, non-permanent walls and other building elements accessible to unauthorized entry). The second frontier
internal volumes and areas of premises are blocked. The third line protects local objects and material assets. At the request of the customer, additional means of so-called alarm and fire alarm systems can be installed at the facility.
Reception and control devices (PKP) and small-capacity concentrators (KME) in security and fire alarm systems are an intermediate link between the primary means of detecting intrusion or fire (sensors) and notification transmission systems (STS) installed on the central monitoring station.
One of the main requirements for PKP and KME is energy independence. In the event of a power outage, it is necessary to maintain control over the alarm loops from the control panel, therefore the control panel and KME must have a backup power supply source.
Technical strengthening and blocking of vulnerable areas of objects by security means should ensure their maximum protection from unauthorized penetration. You can break into any door and open any safe, the only question is time, so it is very important that the alarm systems work on initial stage penetration. In this regard, security sensors when blocking vulnerable places in most cases are installed in front of the border mechanical protection.
The most vulnerable building elements of buildings are external doors, windows and shop windows. Today there is a wide range of sensors with which you can reliably block any structures from opening, destruction or breaking.
Non-visible and non-permanent walls at protected sites are usually reinforced metal bars. Particular attention is paid to those walls that border basements, boiler rooms, ventilation rooms, etc. Non-permanent ceilings and floors are also blocked from destruction and, if necessary, strengthened. To block them, ohmic, infrared and seismic sensors are used.
The second line protects approaches to material assets - these are the internal volumes and areas of premises; in addition, blocking loops are connected to the second line, which includes transition doors and electromechanical traps. The requirements for the second line of security mainly come down to the energy independence of electronic detectors and the right choice places of their installation, adjustment and configuration. The purpose of these actions is to effectively block the volume and area of the protected premises. To protect the second boundaries, infrared, radio wave, ultrasonic, optical-electronic and combined electronic detectors are used. At particularly important objects (bank vaults, storerooms, weapons storage rooms, etc.), several electronic detectors, different in physical principle of operation, are used to block the volume and area of the room.
The third line blocks safes, metal cabinets where material assets or directly objects and exhibits are stored. Safes and metal cabinets are blocked by capacitive detectors and other sensors for opening, overturning and thermal effects. For local blocking of material assets, point or ohmic sensors are used, the installation of which is carried out hidden.
The choice of the type of point sensors and electronic detectors used for all security lines is made taking into account many factors: climatic conditions, design features protected object, probable routes of penetration, security regime and tactics. The main requirements for point sensors are concealed installation, protection from sabotage and compliance with installation rules. Electromechanical - non-volatile, maximum protection of the protected space or area, protection from influences that cause false alarm signals.

For emergency calls to police security squads, alarm buttons are installed at the facilities. Armed mobile groups of GSO units react to their activation first of all. Alarm buttons are installed hidden; when installing them, the factor of accidental pressing must be excluded. The alarm message is transmitted individually telephone lines, direct communication lines, through compaction equipment over involved telephone lines or using a radio channel.
Television surveillance and access control systems are installed at sites as additional lines of protection, usually at the request of customers.
For particularly important facilities, compliance with the requirements for technical strengthening and equipping them with security and fire alarm systems is mandatory. For everyone else, these requirements are advisory in nature.
Depending on the number of measures taken by the “Customer” for the technical equipment of its facility, different kinds security or monitoring the condition of technical equipment installed at the facility. Monitoring can be carried out not only over the state of technical alarm systems, but also over individual vulnerable spots or objects of the facility. Today the spectrum security services provided by GSO is very wide.
However, it should be noted that if you have your own security system, or you work with a commercial control center, of which there are many today, you can turn a blind eye to all the requirements, to put it mildly.
