Certified Fire Protection Specialist (CFPS) — Question 8

When applying rate-of-rise heat detectors, use care to avoid locating them in areas where temperatures might normally be expected to rise as much as ____________ in 1 minute (or less) in order to avoid unwanted alarms.

Answer options

• A. 10 to 15°F (5.6 - 8.4°C)
• B. 12 to 15°F (6.7 - 8.4°C)
• C. 12 to 20°F (6.7 - 11.2°C)
• D. 15 to 20°F (8.4 - 11.2°C)

Correct answer: B

Explanation

The correct answer is B (12 to 15°F) because it represents the temperature range that could cause unwanted alarms if the detectors are placed in areas where such rises are common. Options A, C, and D either fall outside this range or exceed it, leading to potential false positives in alarm activation.
