Asenware AW-CSD501 2-Wire Conventional Smoke Detector

AW-CSD501 is an optical smoke detector connected to conventional fire alarm panels via a two-wire zone loop. It operates on the principle of light scattering by smoke particles entering the measurement chamber; therefore, it provides early warning in slowly developing fires that produce smoke before flaming. It is positioned as a standard detection point in office floors, hotel rooms, corridors, and small to medium-sized facilities established on a zone basis. During ordering, it must not be confused with AW-CSD501-4W: the model with 4W code is a separate four-wire product with relay output, whereas this unit is the 2-wire version.
