(8.3°C/min); <br /> fixed 135°F (57°C) • Automatic environment compensation <br /> • Restriction of Hazardous Substances • ®UL Listed and©ULC Listed; <br /> (RoHS) compliant FM (#3230,3210), CSFM (7272-0067:0258) Approved <br /> Product Overview <br /> The Model FDOT421 photoelectric detector Additionally, Model FDOT421 is plug-in,addressable <br /> incorporates both optical and thermal sensors, and two-wire and multi-criteria detector(with both <br /> uses signals in a neural network to create an photoelectric and thermal inputs)that is compatible <br /> intelligent multi-criteria detector. The with FireFinder®XLS systems. <br /> encompassing result is a detector that provides Model FDOT421 is compatible with the Siemens Fire <br /> enhanced detection to an array of products of Safety field-device programmer I test unit: Model <br /> combustion. DPU, which is a compact, portable and menu-driven <br /> Model FDOT421 utilizes advanced, multi-criteria accessory for electronically programming and testing <br /> detection technology. The multi-criteria detector detectors, easily and reliably. <br /> also has state-of-the-art microprocessor circuitry Model DPU eliminates the need for cumbersome, <br /> (with error check), as well as detector self- unreliable mechanical programming methods, such <br /> diagnostics and supervision programs that is used as dials or switches, and reduces installation and <br /> on Desigo Fire Safety 50-point(Model FC2005), service costs by electronically programming and <br /> 252-point (Model FC2025 I FV2025)and 504-point testing the detector prior to installation. <br /> (Model FC2050 I FV2050) addressable fire alarm <br /> control panels(FACPs). <br /> Multi-Criteria Fire Detector 6150 <br /> SIEMENS Industry, Inc. <br /> Building Technologies Division f n l(t <br />
