Which type of detector detects continuous along a particular path?

The line-type detector is designed to monitor for hazards or changes along a specific path, making it ideal for detecting smoke, heat, or other environmental changes across a linear area. This type of detector consists of a sensing cable or a series of sensing elements that can be placed in a row, allowing it to continuously detect conditions such as smoke or temperature fluctuations along that designated line.

In contrast, point detectors are effective for monitoring discrete locations rather than continuous paths, as they trigger alarms based on specific conditions observed at a single point. Beam detectors typically consist of a light source and a receiver, measuring interruptions in a beam over a distance, but they don't provide continuous monitoring in the same way that line-type detectors do. Area detectors scan and monitor larger spaces but are not focused on a linear path, thus lacking the targeted capabilities of a line-type detector.
