Bosch FAS-420-TT1-SL Silent Analog Addressable Aspirating Smoke Detector, Single-Tube Level Display
Product Code: FAS-420-TT1-SL
Manufactured as a silent version, this analog addressable aspiration detector is connected to a single-tube system and monitors smoke density through its gradual display. Fan noise remains at 38 dB(A) level and can be reduced to 34 dB(A) when additional sound absorption is added. It is preferred in living and working spaces with low noise tolerance. Silent operation allows the device to be installed within the monitored space itself, eliminating the need for a separate technical room.
