Fire suppression systems are the first line of defense against fires and associated risks. This is because fighting a fire is always a race against time. Fire protection systems are often exposed to temperature fluctuations, dust, dirt, and general wear and tear, factors that can affect their functionality. Consequently, specifications, laws, and standards regulate when and how a fire protection system must be maintained.
One of the most important steps in keeping a company or business, an office building, a warehouse, etc., safe is ensuring that the fire protection system is tested and maintained periodically. Indeed, such a system is only as good as the testing and maintenance performed on it. If it doesn’t work when it is most needed, it is useless.
We know that things do not fail on a schedule and that it is impossible to plan for a non-functional sprinkler at hour “h”, in the morning, or in two weeks from now. That is why AVITECH Group has a Maintenance and Technical Support Division, consisting of experienced, certified, and authorized technicians and engineers in the field of fire protection, who can intervene before a malfunction becomes a threat to your employees or property.
Even if nothing fails, turning into a service issue, it is advisable to keep the system in optimal condition. Moreover, maintenance and early recognition of faults increase the reliability of a fire protection system, reducing the total maintenance cost.
Fire Prevention
Fire prevention includes activities such as researching the causes of fires, educating the public (by increasing awareness) about fire hazards, and equipping buildings (or improving existing equipment) to minimize the effects of a fire. Increasing understanding of the causes that can trigger a fire, as well as training people to respond appropriately in such situations, is essential.
New buildings are designed to isolate areas so that the fire does not spread. They also include fire prevention devices, alarms, and evacuation signs; they isolate equipment and materials that could trigger a fire or explode if exposed to flames; or have fire suppression equipment at key points throughout the structure. Additionally, fire-resistant building materials have been developed – such as paints and chemicals used for coating and impregnating combustible materials like wood and fabrics.
In our country, preventive fire education or proactive fire safety culture is still limited. In the collective mindset, almost everything related to fire is attributed to the concerns of IGSU (the firefighters), and few understand the importance of training people and, more importantly, making the best decisions in critical moments. Therefore, both active and passive fire safety measures must be intertwined, aiming to educate and form a proactive fire safety culture.
Fire Detection
Fire safety starts with detecting and locating the source of the fire. Early detection, signaling, and warning will increase response times before the fire settles in and blocks access routes or complicates evacuation.
New early detection technologies reflect the continuous evolution of materials and construction methods. The advantages of early fire detection are evident in almost all environments. From point detection or IR and UV sensors to early detection through aspiration or video cameras, AVITECH offers a wide range of fire detection and suppression solutions that meet the requirements of many applications. Our solutions bear the mark of renowned manufacturers in the field, designed to be easy to install, operate, and maintain.
Point Detection
Multicriteria detectors automatically, dynamically, and continuously adapt to environmental conditions. In the detection process, the characteristics of smoke, temperature, and carbon monoxide are continuously measured and evaluated.
Aspiration Detection
In challenging environments where early detection is not possible using conventional systems (extremely high temperatures, high airflow areas, etc.), early detection through aspiration is a suitable choice.
Explosive Gas Detection
In the industrial field, hazardous substances are part of daily routine. Hazardous gas detection systems will ensure a safe environment for employees.
IR Detection
This uses thermal cameras to identify areas with high temperatures and, therefore, high fire risk.
IR and UV Sensor Detection
Highly responsive sensors and intelligent evaluation algorithms make fire detection very fast with a low risk of false alarms. They have high flame suppression capabilities, high response temperatures, and can be used in explosion hazard areas.
Linear Thermal Detection
The range of applications where the linear thermal detection system can be used covers sterilized rooms where even the finest smoke aerosols are detected, as well as historical and cultural buildings where it perceives high humidity, high temperatures, or contaminated air.
Video Detection
A video-based detection system will detect a fire much faster than a fixed detector installed at ceiling level. The system consists of video cameras and integrated software that operates based on intelligent algorithms.
Alarm Systems
Integrating the fire alarm system with the public address and voice alarm system (PA/VA) greatly simplifies the evacuation operation of a building in danger by transmitting messages. Voice alarms are the most reliable way to evacuate people from an area without panic. Unlike sirens, trained evacuation reduces the time it takes to clear an area.
In terms of public address and emergency alarm systems, AVITECH is a partner of Bosch and Esser by Honeywell. Bosch's range of solutions includes Praesensa, Paviro, and Plena systems.
Installing and using a PSIM (Physical Security Information Management) software platform facilitates the connection of security systems and equipment, safety, communications, IT, and automation, as well as their control through a user interface. These management software platforms turn the task of ensuring safety and security into a process that can be efficiently controlled and managed.
AVITECH installs and integrates security systems and software platforms from manufacturers such as Advancis, AutomaticSystems, Axis, Bosch,
Commend, Honeywell, Fortinet, Fujitsu, Gamanet, Milestone, NEC, Optex, Primion, Sorhea, VuWall.
Sirens, Flashers
Visual alerting with high-intensity lamps in enclosed spaces is as simple as it is useful. With high light output, flash lamps maximize alerting potential. Their robust construction allows them to withstand harsh environments easily.
Additionally, their wide viewing angle and variety of light colors make them ideal for industrial settings. In harsh environments, acoustic signaling sirens are the primary method of alerting. Furthermore, the two can be combined (visual and acoustic) into a single system.
Digital signage
Alongside voice alarms, informing the public through digital displays is increasingly common in public spaces, administrative or office buildings, train stations, airports, shopping centers, and markets. Digital Signage solutions are an important communication tool. The displayed content easily attracts attention, is intuitive, and easy to understand. Displays can automatically take over messages such as useful information, access routes, notifications, and alerts. And very importantly: they can integrate with the national 112 system, dispatch centers, or command centers!
Evacuation
Generally, people do not know what to do in the event of an emergency evacuation, and in the event of a fire, safety elements and evacuation signs are crucial.
Emergency Lighting
Emergency lighting is vital in emergency situations, reducing panic and directing building occupants to exit points. Furthermore, the installation and maintenance of emergency lighting systems are legally required.
Access Control
In an emergency situation, access control systems play a major role in streamlining and facilitating evacuation. Therefore, fire protection systems must be integrated with access control systems — both pedestrian (turnstiles, doors) and vehicle (barriers).
Containment
Fire and Smoke Curtains
A fire-resistant curtain can replace walls or, in some cases, fire doors, allowing for the design of spaces with generous dimensions. They can be used as a passive fire protection solution, limiting the spread of fire and smoke. They are integrated with the fire alarm system and open through gravitational descent.
Fire Doors
Fire doors are specially constructed to slow down and prevent the spread of fire and smoke, and in some situations even the radiant heat transfer. These doors, along with passive fire protection systems, provide round-the-clock protection and allow safe and unobstructed passage. Fire doors can be swinging, sliding, roll-up, or sectional.
Ventilation
Ventilation refers to the intake of outside air into a building and its circulation inside, while the volume of contaminated air is removed. This process can be natural, mechanical, or a combination of both. In a fire protection system context, we talk about smoke extraction. This involves removing gases and fumes generated by materials exposed to fire and high temperatures.
The goal of smoke extraction is to ensure conditions for occupant evacuation and to allow fire intervention measures. Smoke extraction from a building can be done through natural draft (via facade fittings, roof hatches, or smoke vents) or mechanically (through smoke extraction systems – extraction fans and smoke evacuation fans; jet fans).
Fire Extinguishing
Extinguishing with OxyReduct
If conventional fire protection systems are passive — they only react when the fire has started — the OxyReduct system from Wagner, certified by VdS, prevents the development of a fire by introducing a quantity of nitrogen into the protected area. This keeps the oxygen content below the ignition limit of combustible materials. Nitrogen can be produced directly from ambient air using a nitrogen generator. Additionally, it is non-toxic. Thus, OxyReduct technology ensures continuous fire protection and can be adapted to the area it needs to protect.
Extinguishing with Inert Gases
Inert gas fire extinguishing systems are used especially in areas with numerous electrical equipment, which ensure uninterrupted operation of the organization (data centers, technical rooms, communication centers, server rooms, electrical panels, etc.), but also in libraries, archives, museums, art galleries. The main inert gases used as extinguishing agents are: IG100 (Nitrogen), IG541 (Inergen – contains Nitrogen, Argon, and CO₂), IG01 (Argon), and IG55 (contains Nitrogen and Argon). These gases are colorless and do not conduct electricity.
Extinguishing with Water
Sprinkler systems represent solutions used for detecting and extinguishing fires in the initial stage, but do not completely eliminate the need for other fire extinguishing systems. The water extinguishing system has excellent cooling properties, making it an ideal solution for Class A fires (caused by or involving textiles, wood, and other combustible materials).
Extinguishing with Water Mist
Fire extinguishing results from the cooling effects and reduction of the oxygen content that water mist has on the fire source. This system is based on cooling the surface with water particles sprayed using a diffusion head (sprinkler or drencher). Moreover, it can control fires caused by flammable liquids.
Extinguishing with Aerosols
The aerosol extinguishing system is a fire protection technology that uses sodium and/or potassium aerosols as extinguishing agents. The solid extinguishing agent breaks the combustion reaction chain of burning radicals (H₂, O₂, hydroxide), extinguishing the fire promptly. Aerosols are also recommended for extinguishing and suppressing fires in civil, production, or storage constructions.
Extinguishing with Foam
Used to protect areas where flammable liquid substances, plastics, or rubber products are stored, foam extinguishing is an effective extinguishing agent, composed of water, foam, and air. Foam isolates flames from oxygen, reduces the spread of toxic combustion gases, and the ability to combust, stopping the chemical reaction and suppressing the fire.
Electrical System Maintenance
Research shows that unmaintained systems are not as energy-efficient. Over time, normal wear and tear puts stress on components, which can lead to decreased efficiency. Reduced equipment wear means lower risks and less energy wasted during operation.
Keeping maintenance up to date becomes a competitive advantage due to early detection—identifying problems before they turn into major repairs. Additionally, it is an opportunity to reduce the total cost of operation (TCO). Last but not least, it must be performed professionally by qualified personnel.
Preventive Maintenance
This is a combination of activities consisting of regular inspections and replacement of electrical system components. Its goal is to avoid any potential failures and costly subsequent interventions (temporary or permanent). Preventive maintenance is usually performed during a scheduled shutdown to minimize the impact on operations and to adhere to the principle of periodic maintenance.
Field Interventions
The next level is completing preventive maintenance with on-site diagnostic interventions. The aim is to identify symptoms of undetected faults or equipment deterioration before failure occurs. This helps keep the system as close to optimal condition as possible. Inspection and testing results must be documented.
Predictive Maintenance
Predictive maintenance is the most important level in maintenance management to minimize unscheduled downtime, reduce total maintenance costs, and ensure peace of mind regarding the electrical system. Predictive maintenance involves monitoring the condition of the system using advanced technologies based on sensors and tools. It represents the application of the “Just-In-Time” principle to preventive maintenance.
Predicting when the system is likely to fail requires adapted monitoring, meaning a deep understanding of how the system performs its function. For this purpose, IoT (Internet of Things) digital solutions for equipment condition monitoring, along with advanced IT platforms (with embedded algorithms), can provide early warnings and diagnostic issues to predict when the next field maintenance should be performed.
Harsh environments with extreme temperatures, significant temperature variations, high humidity levels, or dust accelerate the aging of equipment in an electrical system. This leads to a higher risk of failure. In this case, the more regular the inspections, the greater the chances of mitigating the risk of failure.
