Which type of smoke detector is listed as being able to sense visible or invisible smoke particles?

The choice of smoke detector that can sense both visible and invisible smoke particles is the smoke detector. Smoke detectors are specifically designed to detect smoke as an indicator of fire, employing different technologies for this purpose.

There are primarily two types of smoke detection technologies utilized in smoke detectors: ionization and photoelectric. Ionization smoke detectors are effective at detecting invisible smoke particles produced by flaming fires, which often have smaller, less visible particles. Photoelectric smoke detectors, on the other hand, are typically more responsive to visible smoke particles produced by smoldering fires, which tend to produce larger particles.

By encompassing both detection methods, smoke detectors provide a comprehensive solution for fire safety, allowing them to react to a wider range of fire types. This dual capability is essential for increasing the likelihood of early fire detection, thereby enhancing safety measures in residential and commercial settings.

While single-station smoke detectors can effectively serve in individual locations, and multi-station alarms allow for interconnected alarms in multiple locations, the description of sensing both visible and invisible smoke particles more broadly applies to smoke detectors in general. Heat detectors, on the other hand, operate on different principles and are designed to respond to changes in temperature rather than smoke particles, making them less versatile in this context
