Which smoke detectors react more quickly to fast-burning fires?

Ionization detectors are specifically designed to react quickly to fast-burning fires, which typically produce smaller, invisible particles as they ignite rapidly. These detectors utilize a small amount of radioactive material that ionizes the air within a sensing chamber. When smoke from a fast-burning fire enters the chamber, it disrupts the ionization process, causing a drop in current and triggering the alarm. This mechanism allows ionization detectors to be highly sensitive to the smoke particulates generated by these types of fires.

In contrast, photoelectric detectors are generally more responsive to smoldering fires that produce larger smoke particles. Multi-sensor detectors combine different technologies to detect a variety of fire types, but their effectiveness depends on the integration of both ionization and photoelectric sensing capabilities. The term "other detectors" is too vague and does not specify any particular type of smoke detection technology, making it less relevant in this context. Thus, ionization detectors are the most suitable choice for quickly identifying fast-burning fires.
