- UL listed to standard 268 - NFPA Style 4, 6, and 7 applicable for signal line circuit - Drift compensation functionality - Low profile appearance - High air velocity rating - High operating-temperature rating - Improved fine mesh insect screen - Low current design - Wide range input voltage - Status LED DESCRIPTION The FDK38U is an analog photoelectric smoke detector operating on the scattered light principle. The detector responds to a broad spectrum of both flaming and smoldering fire conditions. The detector converts detected smoke density to an analog signal of corresponding level, and sends it to FACR The detector has drift compensation functionality by which the detector is able to self-adjust its sensitivity in a pre-determined range when the sensitivity is drifted by some reason. The analog detector equips with a red LED that flashes under normal monitoring condition and turns on under alarm condition.
