Which type of detector is particularly effective in large areas when a light beam is interrupted?

Beam detectors are designed to cover large areas by transmitting a light beam between a sender and a receiver. When this beam is interrupted, typically by smoke, it prompts the detector to activate an alarm. This functionality makes beam detectors especially suitable for high-ceiling spaces, warehouses, and expansive open areas where traditional point detectors might be insufficient.

Due to their design, beam detectors can span significant distances, providing effective coverage and quicker detection across larger spaces compared to other types of detectors. While multi-sensor detectors can also be effective in various environments, they operate under different principles, typically combining multiple sensing technologies for detection rather than relying solely on beam interruption. Photoelectric and ionization detectors are generally used in smaller, localized areas and might not perform as well in the vast expanses that beam detectors are meant to accommodate.
