Fixed detection systems

Detection systems are designed to detect and alert the occurrence of a fire through optical and acoustic alarms. They also send a signal to control panels (located in the control fire station) to pinpoint the fire's location. Fire alarms can be either manual or automatic.

Manual detectors are devices operated manually to activate the fire alarm, while automatic systems analyze the environmental conditions to assess the presence of a fire. They are divided into two categories: those that sample the air and analyze it with smoke analyzers located outside the protected area, and those that utilize sensitive elements, typically temperature or smoke sensors, placed within the area to be monitored.

There is a wide variety of detectors available for different environments, each indicating the presence of a fire based on various operating principles, specifically suited to different types of fires. They can detect the presence of smoke, heat, combustion products, flames, or any combination of these factors.
