The fire alarm installation belongs to the family of so-called danger detection installations and is used to prevent fires. A fire alarm system includes several elements and components used to protect against fires and to contain them. It notably includes sensors (smoke and fire detectors) or even automated extinguishing agents (sprinklers and/or smoke extraction systems). A fire alarm installation revolves around what is called the fire panel.
The fire alarm system can be completed by integrating escape route lighting, key deposits and key safes for firefighters or roller shutter controls.
Activation of a fire alarm system
An alarm is triggered in the event of an acute emergency or fire. The responsible fire station is informed immediately by landline or mobile phone. At the same time, the fire alarm installation often notifies other responsible persons by SMS or voice call.
How does a fire alarm system work?
The fire alarm system relies on the various parameters of the fire detectors to determine whether there is a fire present and to decide what to do. Among others, the following parameters serve as benchmarks:
Dominant development of smoke
room temperature
outbreak of flames
Reaction of installed fire extinguishing systems
What is a fire panel?
The fire panel is the essential element of a fire alarm system. The fire alarm installation collects all incoming signals and information from the building's various fire detection and monitoring systems. The information collected is analyzed and evaluated by the fire alarm installation. The way forward is then determined based on the findings of this assessment.
The fire panel often includes the central control unit and a control panel for the fire brigade. If these elements are installed separately, the control panel and the other components are housed in a fire information center.
Examples of concrete actions of a fire station
Detection of a potential fire hazard and triggering of an internal alarm so that the possibility of a false alarm can first be ruled out before alerting the responsible fire station
Direct transmission and dispatch of a fire signal to the responsible fire station command post
Elevator command and control
Activation of an internal alarm within the building and communication of instructions concerning the evacuation of the site by emergency exits
Closure of fire barriers and opening of smoke extraction elements to prevent the spread of fire
Activation of extinguishing devices installed within the building complex
Opening of doors serving as emergency exits or access routes
fire station
What happens when a fire alarm installation is triggered
As soon as the fire alarm system has been triggered, the fire brigade intervention forces can gain access to the building. Firefighters can locate the fire alarm installation detector that has been triggered by means of a display panel or a fire alarm panel. A control panel for firefighters helps the intervention forces to control the fire alarm installation. If a fire alarm panel is used, the corresponding detector is identified there on a floor plan of the building by means of an LED.
A box contains the access plans intended for the intervention forces. Thanks to these elements of the fire alarm system, firefighters can immediately locate the danger zone and plan the fastest access route. Depending on the size of the building, firefighters may require a printer for access maps when setting up the fire alarm installation. In case of emergency, this printer will print the access plans on site.
Categories of fire alarm installations
When classifying fire alarm installations, the following protection indices are distinguished:
Category 1: Complete protection of the entire building complex
Category 2: Partial protection of one or more fire compartments
Category 3: Protection of escape and rescue routes from a building
Category 4: Protection of equipment, e.g. valuables
Advantages of fire alarm installations
A fire alarm installation has the advantage of allowing rapid detection of fires. Whether people are present or not, it is possibleto take the necessary measures quickly and efficiently. By intervening quickly, informed people can fight fires that have already started and prevent them from spreading if necessary. In particularly sensitive areas, such as schools, hospitals or hotels, a fire alarm installation makes it possible to protect people and immediately alert those present in the building. But a false alarm or the voluntary actuation of fire detectors must also be taken into account by fire alarm installations in order to avoid incorrect reporting.
Disadvantages of Fire Alarm Installations
However, fire alarm systems are also often the subject of criticism. In particular, older installations are criticized for no longer meeting current technical requirements. In addition, this type of installation can only be used by trained personnel with specialist knowledge. In case of danger, any mishandling can have terrible consequences. The opening of the doors to put people in safety is therefore not fully guaranteed. Similarly, improper handling or aging technology can compromise response forces' access to the source of the hazard.
