Description: Seimens FDOT421 in Open Box New Condition TESTED. Model FDOT421 utilizes an infrared light emitting diode (IRLED), and infrared light-sensing photodiode. Under normal conditions, light transmitted by the LED is directed away from the photodiode and scattered through the smoke chamber in a controlled pattern. The smoke chamber is designed to manage light dissipation and extraneous reflections from dust particles or other non-smoke, airborne contaminants in such a way as to maintain stable, consistent detector operation. When smoke enters the detector chamber, light emitted from the IRLED is scattered by the smoke particles, and is received by the photodiode. Model FDOT421 also utilizes a modern, accurate and shock-resistant thermistor to sense temperature changes. The signal processing with detection algorithms allows the detector to first gather smoke and thermal data, and then analyze this information in the detectors `neural network. By comparing data received with the common characteristics of fires or fire signatures, Model FDOT421 can compare these signals to those of deceptive phenomena that cause other detectors to trigger a false alarm.
