Rate of Rise Sensor

The Rate of Rise sensor can be placed up to 2000 feet away from the tattletale unit depending on structures and objects in-between the sensor and the tattletale. It uses two forms of detection. The first monitors how quickly the temperature rises; a 15°F change in ambient temperature, in a period of 60 seconds or less, triggers an alarm event. The second method of detection is when the ambient temperature reaches a level of 194°F. This will also trigger an alarm event. The 3V lithium battery included will typically last for 2-3 years.
