What type of smoke detector is a combination of two different types?

A combination detector merges the functionalities of two distinct types of smoke detection technologies, typically ionization and photoelectric detection methods. This design enhances its ability to respond to a wider variety of smoke particles that result from different types of fires. For instance, ionization detectors are highly sensitive to fast-flaming fires, while photoelectric detectors are better at detecting smoldering fires that produce larger smoke particles. By integrating these two systems, a combination detector offers more comprehensive coverage, making it capable of providing quicker alerts for various fire scenarios, ultimately improving safety in residential and commercial environments. This dual detection capability is particularly valuable in spaces where different fire risks may exist.
