Ionization smoke detectors are examples of which type of detection in this context?

• A. Line-type detection
• B. Non-line-type detection
• C. Hybrid detection
• D. Not used for detection

Answer: (B)

Ionization smoke detectors are point-type sensors—they monitor the air in the immediate vicinity of the device, not along a path or beam across a space. In this context, line-type detection refers to beam or linear detectors that look across a space (a line) and detect smoke along that path. Because ionization detectors respond to smoke density at a specific location rather than along a line, they fit non-line-type detection. Hybrid would imply a combination of line and point methods, which isn’t how an ionization detector operates. Not used for detection isn’t applicable. So the best description is non-line-type detection.
