Repair of an automatic fire alarm system at a facility begins with diagnostics, as it is impossible to properly restore functionality without identifying the cause of the malfunction. In a warehouse, office, or industrial building, a range of typical issues may occur: damaged communication lines during renovations, sensor failure due to contamination or aging, malfunctions in control units caused by power surges. Common causes also include moisture ingress, contact corrosion, poor-quality installation, or natural wear of equipment.

During repair, technicians check all signal loops, cable conditions, connection integrity, and the settings of control units. Diagnostics involve the use of special testers and measuring devices to detect breaks, short circuits, and hidden faults that may not be visible. Even when the problem seems localized—for example, a single non-functioning detector—the entire signal line is inspected to avoid recurring issues later.

The repair process includes replacing faulty components: smoke or heat detectors, manual call points, power and control modules, alarm sounders, and visual indicators. If cables are damaged, the affected sections are replaced in accordance with fire safety regulations and proper installation standards. It is also essential to restore the sealing of enclosures and protect connections from moisture and dust to prevent future breakdowns.

Once all components are replaced or restored, the entire system must be tested. Trial activations are carried out using simulated smoke or heat, the transmission of alarm signals to monitoring stations or the fire department is checked, and the proper operation of sounders and visual alerts is verified. If necessary, software settings are adjusted, and control unit parameters are updated to ensure correct coordination between detection and alert zones.

All repair work must be carried out by organizations licensed to service fire protection systems. This legal requirement ensures the use of certified equipment and compliance with regulations during system restoration. Unauthorized or unqualified work can lead not only to further failures but also to real danger during a fire due to delayed detection or inactive alerts.

Property owners and tenants are responsible for maintaining fire alarm systems in proper working condition. This is not just a formality, but a crucial element in protecting lives, safeguarding inventory, and ensuring business continuity. While regular maintenance minimizes breakdowns, any malfunctions must be addressed promptly. Timely repairs help prevent serious consequences and fines from supervisory authorities.

When planning repairs, it’s important to consider not only the urgency of fixing current issues but also the overall condition of the system. If the equipment is significantly worn or the building’s layout has changed, upgrades or partial replacement with modern, more reliable components may be necessary. A comprehensive approach allows not only for fixing existing faults but also for improving system reliability in the long term.

Warehouses often have large areas, complex layouts, and a wide range of stored materials—from harmless goods to highly flammable substances. As a result, maintenance of fire alarm systems in these facilities faces higher standards and requirements.

Why regular maintenance is necessary

Even the most advanced fire alarm system loses effectiveness without planned maintenance. Dust, moisture, temperature fluctuations, mechanical damage, or equipment wear can lead to malfunctions or complete failure. Regular technical maintenance helps identify and eliminate problems in time, keeping the system ready to respond in case of fire.

Furthermore, the law requires warehouse owners and operators to ensure their fire protection systems are in good working order. Failure to comply can result in administrative penalties, fines, suspension of operations, or even criminal liability if a fire causes serious consequences.

Key Steps in Servicing

1. Visual Inspection of Equipment.
Regular checks of detectors, control panels, signal lines, power sources, and audiovisual warning devices for mechanical damage, contamination, corrosion, and other defects.

2. Functional Testing.
Testing all system components: triggering alarm signals, verifying smoke and heat detector activation, checking the operation of notification devices. Ensuring that the alarm signal is transmitted to the monitoring station or fire department.

3. Power Supply Check.
Testing the main and backup power sources. Charging or replacing batteries if needed.

4. Cleaning and Minor Repairs.
Removing dust, dirt, insects from detector housings and grilles. Replacing damaged or outdated components, checking mounts and housing seals.

5. Software Diagnostics.
For systems with digital control, checking software settings, updating firmware, and reviewing event logs.

6. Documenting Results.
All inspection and test results are recorded in a dedicated maintenance log. This documentation confirms compliance with regulations and supports future planning of maintenance activities.

Maintenance Frequency

Recommended maintenance for warehouse fire alarm systems is at least once per quarter. For facilities with high fire loads or special storage conditions (flammable liquids, chemicals), inspections may be required more often—up to monthly.

Unscheduled maintenance is also mandatory after changes to warehouse layout, equipment relocation, false alarms, or any emergency incidents.

Who Performs Maintenance

Maintenance of fire alarm systems must be carried out by specialists from organizations licensed by the Russian Ministry of Emergency Situations (EMERCOM). This ensures compliance with all regulatory requirements and standards, proper configuration of equipment, and safe system operation.

Choosing a qualified contractor for fire alarm system maintenance in a warehouse is not just a legal obligation but also a guarantee of people’s safety, protection of property, and uninterrupted business operations.

The installation of warning and evacuation control systems is carried out in accordance with the Law of 01.10.2029 N ZRU-226 “On Fire safety” and the rules of 20.10.2020 N 649 “Fire Safety Rules” dated 20.10.2020 N 649 and the manufacturer’s technical documentation. The purpose of these systems is to promptly and clearly inform people in the event of a fire in order to organize timely evacuation.

When designing and installing, the type of warning and evacuation control systems is taken into account, depending on the functionality and area of the facility. There are 5 types of systems: from simple sound systems (type 1-2) for small buildings to multifunctional complexes (type 3-5) that provide voice notification, direction indication, and division of an object into zones to create a staged evacuation.

The method of laying cable lines

Fire-resistant cable products (FRLS, FRHF) laid in metal pipes or ducts are used for warning and evacuation control systems. The routes are carried out along the load-bearing elements, in protected channels. Only cables that do not lose their functionality during a fire during a specified time are allowed.

Arrangement of system elements

The speakers and indicators are placed evenly so that there are no gaps in audibility in each zone. The sound level must exceed the background noise by at least 15 dB, and the speech clarity must be at least 75%. Additionally, light direction indicators are installed, visible from anywhere in the room.

Integration with other systems

Warning and evacuation management systems are integrated into the overall architecture of fire protection — in conjunction with APS, smoke extraction systems, elevator shafts and ACS. Upon receiving a signal from the fire sensors, the alarm and evacuation control systems are automatically activated in a preset logic for each zone of the facility.

Power supply and redundancy

Two-channel power supply and backup power sources are provided for alarm and evacuation control systems. The allowed battery life of the system is at least 24 hours in standby mode and at least 1 hour in emergency mode.

Acceptance and inspections

When the system is put into operation, checks are performed: measuring the sound level at control points, checking voice messages, evaluating the visibility of direction indicators, testing the logic of switching between different evacuation zones. The permissible sound level deviations are not more than 5%.

The installation of warning and evacuation management systems is carried out by organizations licensed by the Ministry of Emergency Situations of the Republic of Uzbekistan. Only certified equipment and fire-resistant cable products are allowed. The quality of the installation is checked as part of a commission check, the results are documented in certificates. Strict compliance with these requirements ensures stable and efficient operation of warning and evacuation management systems in fire conditions.

Fire suppression systems (FSS) are critical for effectively preventing and extinguishing fires. However, to ensure these systems remain reliable and fully functional, regular maintenance and performance inspections are essential.

Why maintenance and inspection are necessary

All equipment degrades over time. Pipes, connectors, valves, and electronic components of fire suppression systems can lose their reliability due to wear, corrosion, pressure loss, or software failures. Without timely inspections and repairs, the system may fail to operate during a fire.

Moreover, operating without proper maintenance violates fire safety regulations and can result in fines or business suspension. Inspections confirm that the system is ready to perform key functions: deliver the extinguishing agent, activate actuators, and run the automated control and alert systems.

Regulatory framework

Maintenance and inspection are regulated:

• Technical regulations in the field of fire safety;
• UzTR. 536-039:2022 General Technical Regulations “On Fire Safety and requirements for fire extinguishing equipment”;
• The Law of the Republic of Uzbekistan, dated 30.09.2009, No. ZRU-226;
• No. 649 Resolution of the Cabinet of Ministers of the Republic of Uzbekistan “On approval of fire safety rules”;
• Passports and equipment instructions.

By law, maintenance can only be performed by an organization licensed by the Ministry of Emergency Situations. The personnel carrying out the work must have the appropriate qualifications and certificates.

Key maintenance procedures

A standard maintenance and inspection routine includes:

1. Visual inspection of all components — pipes, nozzles, pumps, gas modules.
2. Integrity checks — looking for corrosion, damage, or leaks.
3. Testing actuators — valves, dampers, pumps.
4. Monitoring pressure levels and extinguishing agent flow rates.
5. Verifying automatic components — sensors, control panels, alarm systems.
6. Preventive maintenance — flushing pipes, replacing worn or damaged parts.
7. Test activations — simulating actual fire response scenarios.
8. Documentation — preparing a service report with all findings and actions taken.

All tasks are performed in strict accordance with the design and technical documentation.

Inspection frequency

The frequency depends on the system type and is defined in the project documentation:

• Gas systems — every 6 months.
• Water- and foam-based systems — at least once a year.
• Unscheduled inspections — after malfunctions, repairs, or building modifications.

Regular servicing helps ensure reliability and regulatory compliance.

Who is responsible?

The owner of the facility is legally responsible for ensuring timely system maintenance. However, only certified contractors with EMERCOM licenses are allowed to carry out the work. Their technicians inspect, test, repair the systems, and provide the required documentation.

Conclusion

Maintaining and regularly inspecting fire suppression systems is a legal obligation and a critical safety measure. With proper oversight and timely maintenance, FSS can reliably protect people and property from fire-related hazards.

Warehouses, regardless of their business profile, require special attention in terms of fire safety. Storing large amounts of products, often flammable or flammable, makes such facilities vulnerable to fires. The design of a fire alarm system (SPS) must take into account not only the requirements of regulations, but also the actual operating conditions.

Features of warehouse facilities

Designing an ATP in a warehouse requires an individual approach. Highlights:

• The nature and quantity of the product. In the presence of LVL, plastic, paper and other highly flammable materials, detectors with high sensitivity and resistance to interference are needed.
• Architecture and height of the room. High ceilings limit the use of standard spot detectors. Instead, linear smoke detectors are often used, capable of monitoring large volumes of air.
• Division into control zones. Zoning makes it easier to determine the trigger location and speeds up the response of personnel and control systems.
• Automation and interfacing. Modern ATP systems work in conjunction with automatic warning, extinguishing, ventilation control and emergency power outage systems. The project should provide for compatibility.

The sequence of project work

• Object analysis. It includes the collection of initial data, the analysis of potential risks and the definition of categories of premises.
• Formation of requirements. Together with the customer, a technical specification is being developed based on the standards and characteristics of the warehouse.
• Equipment selection. Based on the type of warehouse and the specifics of the stored materials, types of sensors, control devices, communication lines, and power sources are selected.
• Designing. Plans, wiring diagrams, cable routes, equipment specifications, and explanatory documents are being developed.
• Agreement. The documentation is submitted to the regulatory authorities for verification, if required.
• Installation and commissioning. After approval, the project enters the installation and commissioning stage.

Recommendations for choosing solutions

When choosing the type of alarm system, it is important to take into account not only the regulatory requirements, but also the logistics of the warehouse, the intensity of operation, and storage conditions. In some cases, it is advisable to install combined systems, such as smoke and heat detectors at the same time. Backup power and false alarm protection should also be provided.
