The CR-135EWT is a combination rate-of-rise and fixed temperature detector in a case aluminum housing suitable for use in the hazardous locations described above. A set of normally open contacts will close when the ceiling temperature increases at a minimum rate of 15°F (8.4°C) per minute. Closing the contact initiates the direct alarm sequence. Independent of the rate-of-rise operation, the fixed temperature portion consists of a spring-loaded plunger retained by a fusible alloy that releases when the ceiling temperature reaches 135°F (57°C). When released, the plunger strikes the set of contacts and holds them closed. Spacing between detectors on an uninterrupted ceiling is 50 ft. (15.2m) for the rate-of-rise and 30 ft. (9.1m) for the fixed temperature portion. Distance from any wall or partition is 25 ft. (7.5m) and 15 ft. (4.5m) respectively.
