What is the recommended type of detector for environments with high levels of smoke?

In environments with high levels of smoke, a combination detector is highly recommended because it utilizes multiple sensing technologies to provide comprehensive smoke detection. Combination detectors typically integrate both photoelectric and ionization sensing technologies. This dual functionality allows them to be effective in detecting a wider range of fire types, including smoldering fires, which produce a lot of smoke and may not be detected as quickly by ionization detectors alone.

Photoelectric detectors excel at sensing larger smoke particles generated by slow-starting, smoldering fires, while ionization detectors are more responsive to smaller particles from fast, flaming fires. Since high smoke levels can interfere with certain types of detectors, using a combination detector enhances reliability and effectiveness, making it suitable for environments where smoke is prevalent. This feature ensures that potential hazards are detected promptly, increasing the safety of the environment.

In contrast, relying solely on other types of detectors, such as thermal or only photoelectric or ionization, may not provide the same level of comprehensive coverage necessary in high-smoke situations.
