The Potter CR-200-EWT 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). Furthermore, spacing on an uninterrupted ceiling is 50 ft (15m). Also, 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.
In addition, the EWT series meets the requirements of Division 1 “A location where an explosive mixture of gas, vapor, dust, fibers or flyings, and air may exist under normal operating conditions. Besides, the Potter CR-200-EWT cast aluminum enclosure is acceptable for locations requiring Weatherproof, Water-tight, and Dust-tight applications. Class II devices require Dust tight enclosures. The EWT enclosure meets NEMA 4 as well as CSA IV requirements.
