C series intelligent addressable heat detectors are available with fixed temperature alarm thresholds (5251CPI) and rate of rise alarm (5251RCPI).
The detectors measure the temperature in their surroundings and continually report this temperature measurement to the fire panel. The panel will initiate an alarm if the temperature measurement goes above the threshold defined in the panel configuration.
Rate-of-rise (ROR) heat detectors also send an alarm signal to the panel if the temperature increases rapidly. The rate of rise alarm is pre-configured in the detector.
A suitably configured fire panel will display the location of any detector which has triggered an alarm, fault, or maintenance signal.
