Asenware AW-CSD411 2-Wire Conventional Smoke Detector

AW-CSD411 is an optical (photoelectric) smoke detector connected with two cables to the loop in conventional fire alarm systems. It operates on the principle of light scattering by smoke particles entering the detection chamber; this method provides earlier warning than heat detection in slowly developing fires that produce smoke and soot before flaming. It is located in partitioned office floors, hotel rooms, corridors, and small to medium-sized warehouses in installations not requiring addressed infrastructure. AW-CSD411-4W is a separate model in the same family requiring 4-wire supply; the product code suffix indicates the 2-wire version, so the panel loop type must be confirmed before ordering.
