Aspirating Smoke Detection
An aspirating smoke detector is a type of smoke detector, based on a [[wp:nephelometer]] that is capable of detecting the presence of microscopic particles of combustion also known as (smoke) suspended in air by detecting the light scattered from the smoke particles in a sampling chamber.
In the context of [[wp:smoke detection]], the word aspirate means to draw in, which illustrates the basis for how these smoke detectors operate. In most cases aspirating smoke detectors require a fan unit to draw in a representative sample of air from the protected area.
