Certified Fire Protection Specialist (CFPS) — Question 32

Which of the following types of smoke detectors offer advantages in large open areas such as aircraft hangers?

Answer options

• A. Ionization smoke detectors
• B. Photoelectric smoke detectors
• C. Air sampling-type smoke detectors
• D. Video-based smoke detectors

Correct answer: C

Explanation

Air sampling-type smoke detectors are designed to detect smoke in large areas by continuously monitoring the air for particles. In contrast, ionization and photoelectric detectors are less effective in vast open spaces where smoke may be dispersed. Video-based smoke detectors also may not be as reliable in detecting smoke compared to air sampling systems.
