Edwards CF200-EWT Explosion Proof Heat Detector

The Edwards CF200-EWT is a fixed temperature only detector. The fixed temperature portion releases when the ceiling temperature reaches 200°F (93°C). Spacing is 25 ft. (7.6m). The CF-200EWT identified by a black dot and a white dot on the heat collector fin.

A cast aluminum housing encloses a standard Thermoflex® heat detector making it suitable for use in hazardous locations including those requiring detectors that are explosion proof, water and also dust tight.

The Thermoflex® product group includes standard detectors as well as detectors for hazardous locations and moisture-proof applications. Each detector is available in single or multiple circuits with open and/or closed contact configurations. The prefix CR in the model number denotes rate-or-rise and fixed temperature operation. The prefix CF denotes fixed temperatures only. The standard fixed temperature settings are 135°F and 200°F. Units set at 165°F and 285°F are also available.

Installed in areas where corrosive elements exist or washing of walls and also ceiling surfaces is commonplace. The fixed temperature portion and the rate-of-rise operation determined by the ambient temperature. Additionally, Thermoflex® A-type detectors shall be installed in areas where environmental conditions including dust, vapors, insects, etc., would cause an ionization or photoelectric type detector to initiate a false alarm.
