Reconnect the backup battery and restore AC power to the panel. On power-up, the SEM will enter programming to read the current installer code programmed at the panel, then perform a zone scan to read the existing zone information and settings programmed at the panel. During this process, the SEM will also automatically program-specific panel settings needed for the SEM to perform properly. The settings programmed are identified in Installation settings.
The zone scan will automatically begin after the panel is powered up. On the keypad you will see a series of disarms and programming setting changes before seeing MODEM COMM on the screen. If you have a non-alpha keypad, the keypad will show CC instead of MODEM COMM.
