Fire Detection

Fire Detection aims to signal the onset of a fire as early as possible, before it enters a dangerous phase, in order to reduce intervention times and the deployment of fire-fighting resources. 

A fire detection system typically consists of sensors and detection devices distributed in various locations throughout the building. Detectors can be classified according to different types. 

There are several types of fire detection systems, each designed to meet specific needs in terms of safety and fire prevention. 

Among the most common are: 

• Smoke detectors 
• Heat detectors 
• Flame detectors 

Smoke detectors, sensitive to airborne combustion and/or pyrolysis product particles (aerosol), indicate an incipient fire. 

Heat detectors, on the other hand, are sensitive to a rapid rise in temperature, making them particularly effective in environments where smoke might not disperse quickly, such as kitchens or workshops. 

Flame detectors are sensitive to radiation emitted by flames, even at a certain distance, which makes them useful in vast industrial spaces. 

More advanced systems also exist, such as: 

• Multi-sensor detectors: smoke detectors incorporating a temperature sensor that solely assists in the fire alarm decision-making process; 
• "Combi" detectors: sensitive to both smoke and temperature rise or carbon monoxide; 
• Duct smoke detectors. 

We can also mention carbon monoxide detectors, which detect toxic gases produced by fires even before flames are visible. Each system has its specificities and must be chosen according to the characteristics of the area to be protected and the associated risks. An effective fire prevention strategy often involves a combination of these systems to ensure rapid detection and appropriate intervention.

A fire detector is sensitive to a disturbance in its environment. When one of its sensors detects an anomaly such as smoke, flames, or a rise in temperature, it then sends an alarm signal to the centralized system called the Fire Safety Control Panel in the case of a complete safety system. The Fire Safety Control Panel then receives the alarm signal and triggers the building's fire safety activation. Equipment necessary for extraction and the safe evacuation of individuals will then be activated. Simultaneously, devices for smoke evacuation or fire suppression will be engaged. 

Effective fire detection is crucial to ensure safe evacuation and facilitate the rapid intervention of emergency services in the event of a fire.
