Which type of heat detectors are spaced throughout an occupancy with each detector covering a specific floor area?

• A. Spot Detectors
• B. Line Detectors
• C. Fixed Temperature
• D. Photoelectric

Answer: (A)

Spot detectors are arranged to provide distributed coverage throughout a space, with each unit monitoring a defined floor area. This setup creates multiple sensing points so every part of the occupancy is monitored, and a fire in one area triggers a unit nearby rather than waiting for a detector far away. The other options don’t match this pattern: line detectors monitor along a length, such as a hallway or beam line, rather than covering small defined floor areas; fixed temperature describes the triggering mechanism of a heat detector (the temperature at which it activates) rather than how detectors are spaced; and photoelectric refers to a type of smoke detector, not a heat detector, so it isn’t about heat-based area coverage.
