Pertronic 2251CPI Intelligent Addressable Smoke Detector
The 2251CPI Series C smoke detector is an improved version of the 2251BPI intelligent addressable photoelectric smoke detector.
The detector features a smoke sensing chamber designed to detect smoke and diminish stray internal reflections that can cause nuisance alarms. These features were developed to satisfy stringent nuisance alarm immunity tests defined in the US smoke detector standard, UL 268 edition 7.
The smoke level in the sensor chamber is continuously monitored and reported to the fire panel. For each individual 2251CPI detector, the alarm, fault, and maintenance thresholds are programmable in the fire panel configuration software.
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
- On-board drift compensation
- Stable communication with excellent noise immunity
- Smoke sensitivity 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 (note 1)
- 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 7240.7, certificate SMHK25312
- FPANZ Listing PI/369

Notes replacing 2251BPI with a 2251CPI
When the Pertronic 2251CPI is purchased to replace the previous 2251BPI version the fire detection and alarm system may show an "mismatch" fault when the detector is replaced. This means that the physical detector installed on the loop does not match the device profile programmed into the system's configuration. To permanently clear and rectify the fault, a suitably experienced and qualified system integrator must update the panel’s configuration using Pertronic FireUtils® software to match the new device type.
