One of the most important parts of putting out a fire is finding it as soon as possible. When a fire is found quickly, people can get out of the building safely sooner, and fire suppression systems can act more quickly. There are different ways to find out if there is a fire. Heat detection, smoke detection, and flame detection are the three main ways to find a fire.
- Heat Detection
When there is a fire and the temperature in the area goes up, the heat detectors go off. When a certain temperature is reached in an area, the heat detectors go off. Heat detectors tend to have less false alarms than other types of detectors, but they can take longer to find a fire. Heat detectors work best in places where people don’t usually go and in places where smoke detectors don’t work well, like in steamy, humid, or dusty places.
Smoke detectors are activated when smoke is created by a fire. There are several types of smoke detectors that use different methods to detect smoke.
- Ionization:- It is detectors make an electric current between two electrodes by using radioactive material. When a fire makes smoke, the smoke interferes with the ionization, which sets off the alarm. This type of smoke detector can be set off by things like humidity, which can lead to false alarms. These types of smoke detectors work well to find fires that burn quickly.
- Photoelectric:- A light beam is used by these alarms to find smoke. When fire smoke particles pass through the beam, the detectors go off. This kind of detector works well and doesn’t give off many false alarms. Photoelectric detectors are good for small fires that are still burning.
- Combination:- Combination detectors use the technology from both ionization detectors and photoelectric detectors to find both fires that are burning quickly and fires that are smoldering.
- Smoke detectors that don’t work:- Aspirating smoke detection is a way to find a fire as soon as it starts. This kind of detector takes samples and tests the amount of particles in the air. It goes off when the amount of particles in the air goes above normal. This kind of smoke detector doesn’t give off false alarms and works well around sensitive equipment because it can find a fire before it does any damage.
When flames are present, flame detectors can tell if there is a fire. This type of fire detection uses UV and/or infrared sensors to find a flame and set off an alarm.
