Which type of detection is most effective in areas with high ceilings?

Heat detection is particularly effective in areas with high ceilings because it measures temperature increases in the environment. In spaces with high ceilings, smoke can take longer to rise to the level of smoke detectors, making traditional smoke detection methods, like ionization or photoelectric systems, less efficient. Heat detectors are designed to respond to a rise in ambient temperature, which works well under these conditions, as they can trigger alarms based on heat generated by a fire before significant smoke is present.

In high-ceiling areas, multi-criteria detection might provide some level of effectiveness by combining different types of sensing technology, but it is not as specifically designed for tracking temperature changes as heat detection is. Ionization and photoelectric detectors rely on smoke particles, which may not reach the detector promptly, leading to delays in alarm activation. Hence, heat detection stands out as the most suitable choice for effectively safeguarding spaces with high ceilings.
