As part of the Apollo Series 65 Detector Range the 55000-127 Rate of Rise BR Conventional Heat Detector offers a fire detection solution to many applications. The detector can be used with most modern conventional fire alarm panels.
The Apollo Series 65 BR Rate of Rise Heat Detector operates by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient temperature, the other is sealed. In normal conditions, the two thermistors register similar temperatures, but, on the development of a fire, the temperature recorded by the exposed thermistor will increase rapidly, resulting in an imbalance of the thermistors and causing the detector to change to the alarm state.
The Apollo Series 65 BR Rate of Rise detectors are designed to detect a fire as the temperature increases, but they also have a fixed upper limit at which the detector will go into alarm if the rate of temperature increase has been too slow to trigger the detector earlier.
The Apollo Series 65 Detector range incorporates well-proven sensing technologies, together with advances in materials and electronics technology, including an IC based on that used in Apollo XP95 analogue addressable detectors.
Having a wide operating voltage of 9-33V, the Apollo Series 65 detectors can be integrated into security systems, when used with a relay base.
