What is a primary benefit of using optical detectors in fire detection?

The primary benefit of using optical detectors in fire detection systems is their sensitivity to flame light. Optical detectors operate by detecting the specific wavelengths of light emitted by flames, making them particularly effective at identifying fires that produce visible or infrared radiation. This sensitivity enables them to respond quickly to the presence of active flames, allowing for swift firefighting actions and minimizing potential damage.

In contrast, while sunlight can affect the performance of some optical systems, they are specifically designed to minimize these effects. Additionally, although there are detectors that respond accurately to heat or chemicals, these functions are typically associated with different types of detectors, such as thermal or chemical sensors. Optical detectors excel in situations where flame presence is critical to detect promptly.
