The main device used to detect a fire in a fire extinguishing system is a fire detector. These detectors are able to monitor specific indicators or signs of fire in the environment, and once an anomaly such as a fire source or smoke is detected, the system triggers the appropriate alarm and extinguishing procedures.
Here are some common types of fire detectors:
1. Smoke detectors:Detects smoke particles in the air and is one of the most common fire detectors. When the smoke concentration exceeds the set threshold, the system sounds an alarm and activates the corresponding fire extinguishing device.
2. Heat detector:The ambient temperature is measured, and when the temperature rises to a level that could cause a fire, the heat detector triggers a fire alarm.
3. Optical fiber fire detector:Optical signal detection of ignition sources using fiber optic technology. When there is a flame that produces light radiation, a fiber optic fire detector is able to respond quickly.
4. Gas detector:Detect the concentration of specific gases, such as carbon monoxide (CO), methane, etc. Abnormal concentrations of certain gases may indicate that a fire is ongoing.
5. Spark and flame detectors:Specially designed to detect the presence of sparks or open flames, suitable for places with flammable gases or liquids.
These detectors are usually connected to a fire alarm control panel and as soon as a sign of fire is detected, a fire alarm signal is triggered and the corresponding extinguishing system is activated. Such an automated response allows for rapid action in the early stages of a fire, improving fire suppression effectiveness and reducing damage. Fire
