The Siemens FDT421 Heat Detector provides an advanced method of detection, address programming and supervision combined with sophisticated FACP communication. As well as provides the customer with maximum flexibility to program the temperature settings to suit multiple application needs and changing environmental conditions.
The Siemens FDT421 Heat Detector provides an advanced method of detection, address programming supervision combined with sophisticated FACP communication. Also, model FDT421 uses a state-of-the-art thermistor, microprocessor, and advanced signal analysis, providing high reliability and accuracy.
Additionally, Model FDT421 is a cost-effective, two-wire addressable thermal detector that provides a distinctive, advanced feature: seven field-selectable temperature settings specially tailored for application-specific detection needs. The temperature-range settings for each Model FDT421 detector are between 135°F (57°C) 174°F (79°C) with fixed and rate-of-rise programmability. Accordingly, this variance provides the customer with maximum flexibility to program the temperature settings to suit multiple application needs and changing environmental conditions.
Model FDT421 can be configured to provide a low-temperature warning signal at 40°F (4.4°C). This feature along with a compatible FACP serves as prevention of water freezing in pipes for sprinkler systems. In addition, the model FDT421 also utilizes a modern, accurate, and shock-resistant thermistor to sense significant changes in temperature.
