Protected areas
01 / Emergency power supply
Protected Area
Emergency power supply systems ensure the availability of electrical energy in the event of a power outage and thus safeguard the operation of critical infrastructure. They automatically switch to independent power generation as soon as the public grid fails, preventing production interruptions, data loss or equipment damage.
The generator units are typically installed in separate, well-ventilated rooms to ensure safe operation, efficient cooling and easy maintenance.
Risks
- Self-ignition of diesel fuel on overheated surfaces
- Leaks in fuel or lubrication oil lines
- Fire development in switchboards or control units
- Overheating due to insufficient room ventilation
- Soot, oil and dust deposits increasing the fire load
Solution
For rooms housing emergency power supply systems, water mist extinguishing systems are particularly suitable, as they suppress fires quickly and effectively without damaging sensitive components. The fine mist cools the fire source immediately and locally reduces the oxygen concentration — with minimal water consumption and low risk of consequential damage.
In enclosed or safety-critical facility areas, AccurateFlow can be used as an alternative. By precisely introducing inert gases (IG-100, IG-01, IG-55, IG-541), the fire is reliably suppressed — residue-free, gentle on materials and with maximum operational reliability. Activation is carried out via a fire detection system with flame or heat detection, ensuring a rapid response.
02 / Helicopter landing pads
Protected area
Helicopter landing pads are among the most safety-critical areas of a building or industrial site. They are used for the arrival and departure of aircraft, often in close proximity to hospitals, industrial facilities, or utility providers. In addition to their high safety relevance, rapid response times and the protection of people are top priorities. Due to the use of aviation fuels, hydraulic oils, and hot engine components, there are increased requirements for fire prevention and for the technical design of the extinguishing systems.
Risks
- Ignition of kerosene or hydraulic oil on hot engine components
- High surface temperatures of turbines and exhaust streams
- Rapid fire spread caused by flammable liquids and air circulation
- Electrical faults in ground lighting or power supply
- Difficult fire suppression due to open construction and wind conditions
Solution
Foam extinguishing systems with a FireDos foam proportioner are the preferred choice for helicopter landing pads. They distribute the extinguishing agent via fixed nozzles or monitors, forming a closed foam blanket that smothers flammable liquids by cutting off the oxygen supply. At the same time, the fire source is cooled to prevent re-ignition.
The systems are designed to ensure uniform extinguishing performance even in windy conditions or on sloped surfaces. Activation is carried out via a fire detection system with flame or heat detectors and can also be triggered manually — ensuring maximum safety during flight operations and rapid protection for crew members and emergency personnel.
03 / Operating theatres and treatment rooms
Protected area
Operating theatres and treatment rooms are among the most safety-critical areas in medical environments. Complex technical systems, sterile air management, and uninterrupted power supply come together here to enable medical procedures to be performed precisely and safely. Numerous electrical and electronic devices, lighting systems, and ventilation units operate continuously under high load. Fire protection must meet these demanding requirements without impairing the function of sensitive medical equipment.
Risks
- Short circuits or overheating in medical devices or power supplies
- Faults in lighting or ventilation systems
- High fire load due to densely arranged equipment and cable trays
- Risk to patients and staff caused by the failure of critical systems
Solution
For operating theatres and treatment rooms, water-based extinguishing systems integrated into the building protection concept are preferred. Preaction sprinkler systems offer a particularly safe solution: the extinguishing process begins only when two independent activation criteria are met — for example, detection by the fire alarm system and the opening of sprinkler heads.
This reliably prevents accidental water discharge while still ensuring rapid and controlled fire suppression in an emergency. The system protects people, equipment, and infrastructure equally and ensures uninterrupted operation in medical environments.
04 / Server rooms
Protected Area
Server rooms are among the most sensitive areas of modern IT infrastructure. They store, process and distribute central data across networks. These systems require a stable environment with constant temperature, controlled humidity and an uninterrupted power supply. Even short outages or fire events can have serious consequences for operational processes and data security — potentially leading to production stoppages or financial losses. A precisely coordinated fire protection concept is therefore indispensable.
Risks
- Overheating of server and network systems
- Electrical faults or short circuits
- Local heat accumulation caused by improper airflow
- Rapid fire and smoke development even from small ignition sources
- Significant consequential damage from heat, smoke or inappropriate extinguishing agents
Solution
For enclosed IT areas, AccurateFlow provides highly effective and residue-free protection. By selectively introducing inert gases (IG-100, IG-01, IG-55, IG-541), the oxygen concentration in the room is reduced to a level at which fires are reliably suppressed — without affecting the hardware. Extinguishing is uniform and controlled, allowing ongoing operations to continue with minimal interruption.
Activation is carried out via a fire detection system with an aspirating smoke detection system or multi-sensor detection, which identifies even minimal particle concentrations and responds at an early stage. This creates a clean, sustainable and operationally reliable fire protection concept for sensitive IT infrastructures.
05 / Electrical and control rooms
Protected Area
Electrical and control rooms are central control and distribution areas within industrial facilities. They contain switchgear, control units and communication components that ensure the operation of electrical and automated processes. The equipment is often installed on raised floors, beneath which extensive cabling is routed. Due to the high power density and their critical importance to the overall facility, even minor faults can lead to production downtime or system failures.
Risks
- Electrical short circuits caused by overload or insulation faults
- Overheating due to insufficient ventilation
- Ignition of cable insulation or plastic housings
- Technical defects or operating errors
- Dust and dirt accumulation inside switchgear panels
Solution
AccurateFlow protects electrical and control rooms through the targeted use of inert gases (IG-100, IG-01, IG-55, IG-541), ensuring rapid and residue-free fire suppression. The oxygen concentration is reduced to a level at which the combustion reaction ceases, without affecting the sensitive electrical infrastructure.
Activation is carried out via a fire detection system with a highly sensitive aspirating smoke detection system or point-type detectors. This ensures early activation — providing maximum operational reliability and minimal downtime.
06 / Break rooms and office areas
Protected Area
Break rooms and office areas are among the most frequently used spaces in administrative and operational buildings. They are places for work, communication and rest — including individual and open-plan offices, conference rooms, kitchenette areas, break zones and adjacent circulation spaces. These rooms serve not only daily work organisation but also the well-being and safety of personnel.
Due to the large number of electrical devices and the high level of daily use, they place specific demands on preventive fire protection.
Risks
- Faults in electrical devices (computers, monitors, printers, projectors)
- Overheating of lighting or heating systems
- Short circuits or smouldering fires in vending machines or small appliances
- Ignition of easily combustible materials such as paper or textiles
- Unattended devices in kitchenette or break areas
Solution
For office areas and break rooms, water-based extinguishing systems provide fast and reliable response. Water mist systems offer a particularly efficient solution, as they cool the fire source precisely while significantly reducing water consumption and potential consequential damage. In areas with higher fire loads or large room volumes, automatic sprinkler systems ensure comprehensive area protection — providing maximum personal safety and safeguarding operational continuity.
07 / Waste disposal
Protcted area
In waste handling and disposal areas, various residual materials, packaging and recyclables are collected, sorted and temporarily stored. Cardboard and waste compactors reduce storage volume to optimise transport and logistics. Additional outdoor containers are often used for interim waste storage. Due to the high fire load, varying material composition and mechanical processes, these zones present an elevated risk of fire and smoke development.
Risks
- Self-ignition due to heat accumulation or insufficient ventilation
- Large quantities of easily combustible materials such as paper, cardboard and plastics
- Arson or external interference in outdoor areas
- Carelessly discarded cigarettes or sparks from adjacent systems
Overheating of compactors, conveyor systems or compression equipment
Solution
For indoor waste disposal areas, sprinkler or water mist systems provide reliable fire suppression. They extinguish quickly, prevent fire spread to adjacent areas and minimise consequential damage. In outdoor zones, the systems are supplemented with frost-protected or dry pipe networks to ensure operational reliability even at low temperatures.
For larger compaction or collection areas, water spray systems with open nozzles provide area-wide cooling and effective fire suppression. Activation is carried out via a fire detection system with industrial fire or heat sensors, enabling fast and automatic system activation in the event of an incident.
When automatic extinguishing monitors are used, detection and precise targeting of the monitor are handled by the DIAS detection system. The addition of a foam concentrate (FireDos) can further increase extinguishing efficiency..
08 / Parking areas
Protected area
Parking areas and underground car parks are integral components of modern building structures. They provide parking spaces for employees, customers and visitors, and are often designed as multi-storey or underground facilities. Due to the high vehicle density, limited air circulation and intensive use, they place special demands on ventilation, smoke extraction and fire protection. In addition to ensuring personal safety, the primary focus is on containing vehicle fires and preventing the spread of smoke.
Risks
- Technical faults in vehicles (e.g. short circuits, battery or fuel fires)
- Careless smoking or open flames
- Arson or intentional ignition sources
- Rapid fire and smoke development due to confined structural layout
- Heat accumulation and insufficient smoke extraction in lower levels
Solution
In parking structures and underground car parks, water-based extinguishing systems are primarily used to quickly suppress fires and prevent them from spreading to adjacent vehicles. Water mist systems from Marioff or VID Firekill nozzles provide a particularly efficient and resource-conserving solution, as they achieve strong cooling performance with minimal water consumption and reduce consequential damage.
For large ceiling heights or expansive parking decks, automatic sprinkler systems are used. They are supplied via the existing firefighting water network and ensure uniform area coverage.
A fire detection system with smoke or heat sensing ensures early alarm activation — providing maximum protection for people and property in highly frequented parking areas.
Modern hospitals are highly complex buildings in which medical, technical, and logistical processes must interlock seamlessly. A reliable fire protection solution is therefore indispensable — both to protect people and to ensure safe, uninterrupted clinical operations.
Already in the planning phase, structural and technical fire protection measures are carefully coordinated to guarantee a holistic safety concept. Depending on the area, fire detection and extinguishing control panels are used, as well as sprinkler systems for comprehensive building protection, water mist or water spray systems for technical rooms and sensitive equipment areas, and foam or inert gas extinguishing systems for laboratories, power supply rooms, and server zones.
This concept is complemented by wall hydrants, smoke and heat exhaust ventilation systems (RWA), and portable fire extinguishers. In this way, ACCURO ensures comprehensive safety at every level — from the intensive care unit to the energy control centre.
The protection of archives and museums places exceptionally high demands on fire detection and extinguishing technology. These facilities store cultural and artistic assets of immense material and emotional value — often made of highly combustible materials such as paper, wood, or varnishes.
An effective fire protection concept is based on two key components: first, the earliest possible fire detection to identify emerging fire sources in time, and second, extinguishing technology that avoids consequential damage and does not compromise sensitive objects.
Recommended solutions include aspirating smoke detection systems (ASD) for the early detection of the finest smoke particles, water mist systems for efficient fire suppression with minimal water usage, and inert gas extinguishing systems (AccurateFlow), which are particularly effective in archives — residue-free, gentle on materials, and cost-efficient even for large room volumes.
ACCURO relies on environmentally friendly and sustainable extinguishing systems that protect art and cultural assets reliably without endangering their integrity.
In garages and underground car parks, there is an increased fire risk due to highly flammable fuels, hot vehicle components, and the continuous supply of oxygen. In the event of leaks or damaged fuel tanks, an explosive gas mixture can also form quickly.
To minimise this risk, various systems are used: fire detection systems with special heat detectors and CO sensors, sprinkler or water mist systems for fire suppression and cooling, smoke and heat exhaust ventilation systems (RWA) for rapid smoke removal, as well as frost-proof designs using dry pipe systems or antifreeze solutions.
ACCURO develops holistic protection concepts for both new and existing facilities — ensuring safe underground garages and parking structures, even under demanding winter conditions.
In aircraft hangars, there is an especially high fire risk due to flammable liquids, hydraulic oils, and fuels. To effectively control this hazard, sprinkler systems with foam concentrate injection or pure foam extinguishing systems using light foam are typically employed. These systems are designed in accordance with the guideline for fire class HH and ensure area-wide extinguishing coverage combined with rapid response times.
Helicopter landing pads also place high demands on fire protection. They are often located on hospital rooftops or high-rise buildings, making them difficult for emergency crews to access. In the event of an emergency, the extinguishing process must therefore operate fully automatically and with absolute reliability. A proven concept uses heavy foam as the extinguishing agent, combined with a ring main system that supplies foam nozzles around the landing area. A combination of jet nozzles and spray nozzles ensures complete surface coverage, while pop-up nozzles embedded in the landing platform automatically extend under pressure and distribute the foam evenly.
This technology enables fast, efficient, and comprehensive fire suppression while also protecting adjacent building sections from radiant heat. With these solutions, ACCURO provides state-of-the-art, standards-compliant, and ready-to-use systems for hangars, landing platforms, and aviation infrastructure.
