Bosch FAS-420-TT2 Analog Addressable Aspirating Smoke Detector, Dual-Tube Smoke Level Display
Product Code: FAS-420-TT2
A dual-tube inlet aspiration detector addressed to the LSN loop evaluates air samples from two separate lines within the same body. Smoke density is read gradually, while alarm information is displayed discretely. Additionally, the two ordered sensing modules are selectable with response sensitivities of %0.5/m, %0.1/m, or %0.015/m. Operation of two lines under a single address reserves capacity on the loop and reduces cabling costs.
