What is a line detector used for in a fire alarm system?

A line detector is specifically designed to sense heat over large open areas, making it well-suited for environments where traditional point detectors might not be as effective. These devices typically use a cable or a series of sensors that are distributed along a line, enabling them to monitor temperature changes effectively over expansive spaces. This capability is particularly valuable in warehouses, large industrial settings, or other sizable areas where heat buildup could indicate a fire risk.

In addition to the physical characteristics of line detectors, their ability to cover wide areas allows them to respond more quickly and accurately to heat sources compared to devices designed for confined spaces or specific points. This broad detection capability can help facilitate faster emergency responses and enhance overall fire safety.
