Question 202Safety & Environmental - QMED

The correct answer is A) Fixed temperature. The component shown in the illustration SF-0004 is a fixed temperature fire detector. Fixed temperature detectors are designed to activate when the surrounding temperature reaches a predetermined set point, typically between 135°F and 250°F. This type of detector is commonly used in fire detection systems where a rise in temperature is the primary indicator of a fire, such as in machinery spaces or other areas where a steady temperature is expected. The other options are incorrect because line-type pneumatic, combined fixed temperature and rate-of-rise, and rate-of-rise detectors operate on different principles and are not compatible with the component shown in the illustration.
