5251CPI Detector

AA Heat Detector, C Series


The 5251CPI detector is available only in ivory. White and black versions are not yet available.

The C series analogue addressable heat detector (5251CPI) measures the temperature in its surroundings and continually reports 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.

A suitably configured fire panel will display the location of any detector which has triggered an alarm. The fire panel can also identify any active detector by lighting up two red LEDs on the detector housing.

The LEDs briefly light up (“blink”) when the detector is polled. The fire panel may be configured to disable LED blink.

The detector’s address on the analogue addressable loop circuit is easily configured using rotary address switches.
