Bosch FAS-420-TT2-SL Silent Analog Addressable Aspirating Smoke Detector, Dual-Tube Level Display
Product Code: FAS-420-TT2-SL
It is a silent version analog addressable aspiration detector supplied from a single body by two tube lines. Thanks to discrete alarm information and smoke level display, the difference between pre-alarm and main alarm can be read; by installing two sensing modules, the monitoring area is expanded or dual-detector redundancy is established. Fan noise reduced to 38 dB(A) ensures compatibility with quiet spaces. Cross-validation of the two modules reduces false alarm risk.
