Edwards Signaling 281B-PL heat detector offers combination rate-of-rise and fixed temperature detection. A temperature increase at the sensor of 15°F (9°C) or more per minute activates the rate-of-rise feature. While, if the temperature of the center disk rises to the sensor’s rated temperature, the fixed temperature element activates.
