Description: The 245A series heat detector is activated at fixed temperature and resets when the temperature returns to normal.

Features:

  • Fixed Temperature

  • Resettable

  • Open circuit

  • Easy to install

Rate-of-rise heat detector


Category: Fire alarms
Sub-category: Fire detection
Code: CR135


Description: The CR-135 model is a combined rate-of-rise and fixed-temperature detector. A set of contacts that are normally open will close when the ceiling temperature increases at a (minimum) rate of 8.4° C (15° F) per minute. The closing of the contacts initiates the fire alarm sequence. The fixed temperature function, which operates independent of the rate-of-rise function, consists of a spring-loaded plunger that is held by a fusible alloy that releases when the ceiling temperature reaches 57° C, (135° F). When the plunger is released, it strikes the contacts and holds them closed. Rate-of-rise detectors must be placed at 70’ (22 m) intervals on flat ceilings, and fixed temperature detectors 40’ (12.5 m) intervals.

Features:

  • Contact rating: 3 A at 125 V AC, 1 A at 28 V DC, 0.3 A at 125 V DC, 0.1 A at 250 V DC

  • Dimensions: diameter = 5.25” (13.4 cm), height = 2.0” (4.85 cm), weight = 0.41 lb. (330 g).
