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 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.
