Multi-channel aspirated smoke detector

摘要

An aspirated smoke detector includes a manifold coupled to a smoke sensing chamber of the smoke detector. The manifold couples ambient smoke from a plurality of locations to the smoke sensing chamber. A location of the origin of the smoke can be determined by associating a member of a plurality of a different type of smoke sensor with each of the locations. When smoke is detected in the sensing chamber, the members of the plurality can be interrogated to determine the location of the origin of the smoke in the sensing chamber.
