A fire detection system is one that is designed both to detect and to warn when fire signals are detected. Its main mission is to automatically locate the fire and implement the sequence of the alarm plan that has been incorporated into the detection center.
The effectiveness of such a system is determined by how early fire signs are detected. This is a point of vital importance, since, depending on the type of combustion that the flammable materials present in the place where the system is to be placed, a specific detection system will have to be chosen.
Another factor that determines the choice of a fire detection system is related to the type of building and the area to be protected, as well as the environmental conditions that are put at risk. At this point factors such as the influence of the outside wind, construction materials, ventilation, etc. On certain occasions it may be necessary to install supplementary structural protections for the fire detection system to be effective.
Having said this, it should be noted that when choosing the most appropriate type of fire detection system, the choice of the most efficient and appropriate system for the conditions of each place should be established as a priority, even if this means having to install a more expensive system.

Types of Detectors
The detectors are in charge of detecting the fire. The mission of these devices is to detect any of the manifestations that accompany the fire, such as smoke, gases, temperature or ultraviolet radiation. Therefore, depending on the type of fire that can occur in an installation, it is convenient to choose the type of detector or detectors to be installed properly.
The Types of Detectors Currently on the Market are:
- Smoke detectors. They can be ionic (they detect combustion gases, currently in disuse) and optimal (they use photoelectric cells that are activated when darkened by smoke or illuminated by reflection of light in smoke particles)
- Heat detectors. They detect the change in temperature in the environment.
- Radiation or flame detectors. They detect radiation from fire, so they only detect flaming fires.
Fire Detection Systems
Fire detection systems are made up of a detection center, detectors, push buttons, siren and, in some cases, an extinguishing system. In general, fire detection systems can be of two types: conventional and analog.
Conventional fire detection systems are designed to last with minimal maintenance. This, added to the fact that they are easy to handle and assemble, means that these systems are commonly used in small commercial premises, private garages and other small installations.
In these systems, the detection center only reports the area in which the alarm has been triggered, but not the exact location of the detector that gave the alert. This may be sufficient for small areas, but insufficient for large areas.
Analog fire detection systems are much more complete, since they individually recognize each element of the system, be it a detector, a button, etc., so that the alarm of the control panel reflects the exact point where the fire occurs. warning sign.
These analog fire detection systems are also capable of controlling elements of the building installation that are important for fire control or building evacuation, such as air conditioning systems or fire doors.
Analog fire detection systems can also incorporate, in addition to conventional fire extinguishing modules, other types of extinguishing, such as automatic gas extinguishing. Furthermore, these systems can be controlled by the same analogue exchange.
