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.

Features

• Intelligent addressable (IA) communication with fire panel
• Temperature threshold configurable in the fire panel
• Rotary address switches for setting the address on the intelligent addressable loop
• Fire panel identifies active detectors by lighting up two red LEDs on the detector housing
• LEDs briefly light up (“blink”) when the detector is polled
• LED blink may be disabled via the fire panel configuration
• Dual LEDs for visibility from all normal viewing angles
• Optional remote LED indicator available
• Magnet test function activates detector and bypasses inbuilt delays to facilitate testing
• Compatible with B501AUS, B501AP, and other System Sensor intelligent addressable bases
• Compatible bases provide an optional anti-tamper feature
• SAI Global StandardsMark listed to AS 7240.5:2018, certificate SMHK25312
• FPANZ Listings PI/267 (5251CPI-xx), PI/268 (5251RCPI-xx)
