Question 262Safety & Environmental - Assistant Engineer

The correct answer is B. Fixed temperature. The component shown in the illustration SF-0004 is a fixed temperature fire detector. This type of detector is designed to activate when the surrounding temperature reaches a predetermined fixed temperature, typically between 135°F and 174°F. Fixed temperature detectors are commonly used in fire detection systems where a rapid rise in temperature is expected in the event of a fire. The other options are incorrect because: A) Line-type pneumatic detectors use air pressure changes to detect fires, C) Rate-of-rise detectors activate based on the speed of temperature increase, and D) Combined fixed temperature and rate-of-rise detectors use both fixed temperature and rate-of-rise principles, but the component shown is specifically a fixed temperature detector.
