The takeover installation process is similar to the installation process described above, except the control panel of the legacy system is replaced; therefore, only the differences with the installation described above are provided here. The takeover approach of an embodiment uses the existing RS485 control interfaces that GE Security and iControl support with the iHub, touchscreen, and Concord panel. With these interfaces, the iHub is capable of automatically enrolling sensors in the panel. The exception is the leverage of an iControl RF card compatible with legacy systems to ‘takeover’ existing RF sensors. A description of the takeover installation process follows.
