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 dust tight. The suffix EWT denotes a unit that is suitable for areas described as: Class I: Groups C and D, Class II: Groups E, F, and G, Class III: Applications requiring Special Purpose Enclosure Types III, IV and V, Weatherproof, Water-tight, and 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 Model CR200EWT is a combination rate-of-rise and fixed temperature detector that operates in the same way as the CR135EWT, with the exception that the fixed temperature portion releases when the ceiling temperature reaches 200°F (93°C). Spacing on an uninterrupted ceiling is 70 ft. (21.3). The CR200MP is identified by a white dot on the heat collector fin.
