An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.
The prealarm LED is lit when one device has tripped. The prealarm LED may also be used if an addressable smoke detector registers low levels of smoke in the detection chamber, but not enough to trigger a full alarm.
