Zone scan
1. 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.
2. 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.
◦ Zone scan (~5 minutes):
Caution: Do not touch the panel or keypad.
◦ If you do not see the MODEM COMM message appear on the keypad during zone scan and instead notice
the keypad scrolling through each zone individually, the SEM is using an alternate zone scan method because
it is unable to access the downloader. For troubleshooting this behavior, see
3. When the zone scan is complete, the keypad will display the home screen. The equipment list is now available on
the Partner Portal equipment page and the MobileTech Remote Toolkit and all user codes are synced to the
Customer Website.
