Experts in fire protection

Overview

Hotels typically have a high density of people. As people spend their time in the hotel rooms both at night and during the day, personal safety must be ensured around the clock. Especially in attractive inner city locations, hotels are often built on many floors. This gives rise to special requirements regarding fire protection, since for example the turntable ladders of fire brigades are generally no longer of sufficient height to rescue hotel guests and staff during an emergency.

The risks that may lead to a fire are manifold. Careless smoking in hotel rooms is one of the most common causes of fire. The constant running of light systems may lead to overheating and trigger a fire. In addition, technical defects in auxiliary facilities, e.g. HVACR rooms or emergency generators, may cause the outbreak of a fire.

Fires often have devastating effects, especially in hotels built to a great height. Fires can spread very rapidly and uncontrollably via flashover. On higher floors, the safety of persons is particularly at risk through long and possibly blocked escape and rescue routes.

Flames, smoke, gas emissions, heat – fire has many facets. Minimax has the right fire detectors for the various areas within a hotel. Their signals converge in the fire detection and extinguishing control panel, which issues an alarm to the people at risk and the fire brigade. In addition, the Minimax panel monitors the installed fire protection system for proper functioning and electrically triggers the extinguishing systems that are not equipped with their own triggering elements, e.g. sprinkler systems.

A sprinkler system ensures overall building protection in a hotel. Minimax offers a broad range of sprinkler types and special sprinklers that allow for ideal adaptation of the sprinkler system to the respective installation situation in the various protected areas.

Areas with special fire risks or deployment conditions require - either in addition to or instead of the sprinkler system - a tailored volume or local protection system. For this reason, deluge systems, Minifog water mist extinguishing systems, Oxeo inert gas extinguishing systems, halocarbon extinguishing systems and KS 2000 kitchen protection extinguishing systems are used in hotels.

Structural fire protection, as well as technical systems by Minimax Mobile Services, such as fire extinguishers, wall hydrants and smoke and heat extraction systems, complete fire protection in hotels.

  1. Hotel rooms
    1 Hotel rooms

    Protection zone

    Hotel rooms are retreat and relaxation rooms, mostly occupied at night by guests. During the day it is mainly staff that enter the rooms. There is often a very stringent demand for convenience and interior design in these rooms. For this reason, the rooms have already been fitted extensively with electrical devices, and this trend can be expected to continue in future.

    Risks

    • Defective electrical devices, e.g. kettles, radio, or TV
    • Incompletely extinguished cigarette butts
    • Highly flammable materials

    Fire Protection

    Minifog EconAqua water mist extinguishing systems are a water and space-saving alternative to sprinkler systems in hotel rooms. In hotel rooms, they can be designed as extended coverage wall sprinklers, which means that a standard room can be safely protected against fire with a single sprinkler. When using undercover sprinklers, the extinguishing system fits particularly unobtrusively into the ceiling. 

  2. Kitchens
    2 Kitchens

    Protection zone

    No gastronomy area can do without a kitchen. Food is generally prepared directly on site in kitchens of varying dimensions. This is where foods are prepared, cooked and often kept warm until served.

    Risks

    • Overheated frying and grilling plates
    • Unprofessional operation of appliances
    • Technical defects in electrical appliances
    • High fire load due to large quantities of grease used

    Fire Protection

    The KS 2000 kitchen protection extinguishing system offers ideal fire protection for cooking stations and deep fryers. This system triggers at an incipient outbreak of fire within seconds, and fights even grease fires using the special extinguishing agent Febramax-S. Sprinkler systems protect the building.

  3. Archives
    3 Archives

    Protection zone

    Archives house documents and information in the form of paper files or data carriers. Shelving bays or mobile storage racks make for transparent storage and as needed for quick access to specific information. The ceiling height is typically used to the limit.

    Risks

    • Technical defects in devices such as the motors of electric mobile storage racks
    • Overheating of ceiling lighting
    • Highly flammable materials

    Fire Protection

    Sprinkler systems installed for the overall protection of the building typically provide the necessary safety in archives. The use of Preaction sprinklers prevents an unintentional triggering of the extinguishing system caused by accidental damage to a sprinkler. Oxeo inert gas extinguishing systems completely exclude water damage to archived materials. They are also an optimal solution if the distance between the upper edge of the shelves and the ceiling is too narrow for sprinklers. Oxeo extinguishing systems are triggered by a fire detection system using HELIOS AMX5000 aspirating smoke detectors.

  4. Waste disposal
    4 Waste disposal

    Protection zone

    Large quantities of different types of packaging waste are often collected in separate recycling and waste collection areas. Cardboard and trash compactors reduce the storage volume. In addition, waste is also stored in containers in outside areas.

    Risks

    • Auto-ignition in case of insufficient ventilation
    • Large quantities of highly flammable organic material
    • Arson in outdoor areas
    • Carelessly discarded cigarette butts

    Fire Protection

    The sprinkler systems used for the protection of buildings effectively combat fires also in the case of burning organic waste and packaging materials. Outdoor areas can be included in the protection range, in which case a dry system or, alternatively, Minimax PipeGuard Antifreeze prevents freezing of the extinguishing water and protects against possible frost damage. If large quantities are stored, a deluge system with open nozzles should rather be selected. This system is triggered by a fire detection system with UniVario industrial smoke detectors.

  5. Shops and sales floors
    5 Shops and sales floors

    Protection zone

    Sales floors frequently present a particular architectural challenge. It is not uncommon to have sales floors with elaborately designed entrance areas made of different materials, as well as with an extensive lighting system and in open construction. In addition, atria and open galleries enhance a sense of exclusivity. Characteristic for all sales outlets is regular exposure to the public and, accordingly, a high demand for human safety.

    Risks

    • Large number of highly flammable goods
    • Short circuits on permanently running projectors
    • Defective lighting equipment
    • Arson

    Fire Protection

    Undercover sprinklers are especially suitable when a sprinkler system is used. They fit harmoniously and inconspicuously into a ceiling pattern. Thus there is no discrepancy between reliable fire protection and the demand for discerning aesthetics and furnishings for prestigious shops and sales floors. 

  6. Server rooms
    6 Server rooms

    Protection zone

    Server rooms are important, sensitive areas. In these rooms, data of high importance for business operations is stored, managed and exchanged over the network. The irretrievable loss of this data through a fire may have considerable economic consequences for productivity or even the future of a company.

    Risks

    • Overheating of technical equipment
    • Defects such as short circuits
    • Considerable damage even in the case of small fires

    Fire Protection

    For small and medium-sized server rooms, the MX 1230 extinguishing system is the ideal solution. It gives residue-free extinguishing using the innovative Novec™ 1230 extinguishing agents and requires very little space. Oxeo inert gas extinguishing systems are ideal for large server rooms. The MX 1230 extinguishing system and Oxeo inert gas extinguishing systems are triggered, and fires are detected, by a fire detection system using a HELIOS AMX5000 smoke aspirating system.

  7. Riser ducts
    7 Riser ducts

    Protection zone

    Larger buildings must be equipped with numerous power and data cables and pipelines. These run between the floors of the building in bundles through riser ducts. On each floor, supply lines branch off to the various stories. Riser ducts provide protection against damage and visually cover up the cabling at the same time.

    Risks

    • Short circuits in power cables
    • Drafts and vertical alignment of the duct are conducive to a rapid spread of the fire

    Fire Protection

    Riser ducts are reliably protected by the sprinkler systems through the sprinkler systems installed for the protection of the building. For shaft heights of more than 15 m, deluge systems are used. In this case, a fire detection system with punctiform smoke detectors ensures automatic triggering of the extinguishing system.

  8. Wellness areas
    8 Wellness areas

    Protection zone

    Wellness areas are becoming increasingly popular. They come in all sizes: from a small space with a sauna or a whirlpool, to large SPA areas with a fitness room, solarium, and a pool.

    Risks

    • Defective power-consuming electrical devices, such as sauna stoves, solariums, or fitness equipment
    • Highly flammable devices made of wood, plastic or foam

    Fire Protection

    Space and water-saving Minifog EconAqua water mist extinguishing systems in particular are ideal for protecting wellness areas against fire. These systems can be connected to an existing sprinkler system protecting the building. In areas with higher ceilings, sprinkler systems provide reliable fire protection. In doing so, the sprinklers are selected and installed in accordance with the environmental conditions. Hence for example a special version of the Preaction sprinklers is used in saunas. The triggering temperature of this "sauna sprinkler" is significantly higher compared to conventional sprinkler bulbs. As a protection against unintentional damage, the sprinkler heads can be equipped with a protective mesh. 

  9. Offices
    9 Offices

    Protection zone

    Offices, conference rooms and dining rooms are generally used by staff and guests. In addition, staff members may also retire to break rooms or smoking rooms and to kitchens during work. Corridors run through the entire building, serving as a main traffic route.

    Risks

    • Defective electrical devices such as projectors and computers
    • Overheating of the lighting
    • Short circuits at vending machines

    Fire Protection

    Minifog EconAqua water mist extinguishing systems offer space- and water-saving protection and can be connected to an existing sprinkler system. In areas with higher ceilings, sprinkler systems provide reliable fire protection. 

  10. Atria
    10 Atria

    Protection zone

    Atria are representative central areas of a building, which serve as entrance areas and can to some extent also be used as event locations due to their architecture and dimensions. Some atria extend across the entire height of the building and are lit from above by natural light through a glass dome. Due to the central location of the atria, most passages branch off from the atrium to almost all other areas and levels of a building.

    Risks

    • Overheating of the lighting
    • Defects in electrical devices such as promotional displays
    • Event-related or seasonal decorations, e.g. with candles

    Fire Protection

    The special construction and dimensions of atria make the installation of automatic extinguishing systems indispensable. In spaces with a ceiling height of more than 15 m, deluge systems ensure reliable firefighting. In this case, the extinguishing system is triggered by a fire detection system with linear smoke detectors. For lower ceiling heights, the sprinkler system used for building protection is a suitable alternative. 

  11. Utility rooms
    11 Utility rooms

    Protection zone

    HVACR rooms are an absolute key area for the proper operation of a building. In addition to switching and control systems for the elevator system, they house safety-relevant HVACR systems, such as overpressure control, that keep the escape routes smoke-free in the event of fire. The facilities are particularly sensitive and must function without interruption - only then can the operation be maintained without problems on all floors of the building.

    Risks

    • Overheated ventilators, compressors and cooling units
    • Short circuits on electronic components

    Fire Protection

    In case of particularly high availability requirements, e.g. for the switching and control system of the elevator system, residue-free extinguishing with Oxeo extinguishing systems or MX 1230 fire extinguishing systems makes sense. A fire detection system using the HELIOS AMX5000 smoke aspirating system triggers the extinguishing system.

    Alternatively HVACR rooms can be integrated into the overall building protection through sprinkler systems. If necessary, the use of Preaction sprinklers makes an unintentional triggering of extinguishing system virtually impossible. 

  12. Emergency power generators
    12 Emergency power generators

    Protection zone

    Emergency generators are often housed in separate premises. During a power failure, these generators secure the power supply, maintain business operation and prevent financial loss due to an operational interruption.

    Risks

    • Diesel fuel, which ignites on hot surfaces
    • Leaking lubrication oil

    Fire Protection

    For local protection of the emergency generator, Minifog ProCon water mist extinguishing systems are ideal. These can be connected to the sprinkler systems installed for building protection purposes and fight fires quickly and effectively through open water mist nozzles. Minifog ProCon water mist extinguishing systems are triggered by a fire detection system that uses UniVario flame or heat detectors to detect fires.

  13. Parking areas
    13 Parking areas

    Protection zone

    Extensive parking facilities are especially convenient for customers and employees. Due to space limitations, parking is often provided in highly frequented, multi-story car parks.

    Risks

    • Technical defects in parked vehicles
    • Careless smoking
    • Arson
    • Rapid spreading of fire and development of smoke

    Fire Protection

    Minfog EconAqua water mist extinguishing systems offer a water and space-saving fire extinguishing method for underground car parks. For higher ceilings, sprinkler systems are a reliable alternative.
