SILENT KNIGHT SD505-APS PHOTOELECTRIC SMOKE DETECTOR - USED

The SD505-APS is particularly suited to detecting dense smoke typical of fires involving materials such as soft furnishings, plastic, foam or other similar materials which tend to smolder and produce large visible particles. The detector features automatic compensation for contamination and a simple detector calibration test procedure that can be run from the panel or remotely (using the WindowsTM based downloading software).
