Detectors located in specific locations are known as what?

The term that best describes detectors located in specific locations is "spot detectors." Spot detectors are designed to monitor environmental conditions, such as temperature or smoke, at discrete points within a space. This means they are intended to trigger an alert or alarm when specific parameters are met in that exact location.

Spot detectors are often used in scenarios where it's critical to identify the source of a fire or hazardous situation quickly. Because of their focused detection capabilities, they can effectively respond to localized incidents in a timely manner.

In contrast, area detectors evaluate larger sections of a space, potentially leading to less precise detection. Point detectors generally refer to any device that samples conditions at specific points but typically encompass a broader range of detection than just fire detection. Surface detectors are less common in fire safety contexts and might refer to fire detection systems that assess conditions over wider surfaces rather than at specific points.
