Bosch FAS-420-TP1 Analog Addressed Aspirating Smoke Detector, Single Tube LED Indicator

An aspirating smoke detector operating in the analog addressed LSN line; continuously monitors by drawing air samples from single tube line. Red, yellow, and green LEDs separately distinguish operating, fault, and alarm status. Detection module with %0.5/m, %0.1/m, or %0.015/m sensitivity is selected separately according to design. Because suction holes are individually monitored, a blocked point registers as a fault to the panel and the system does not silently go blind.
