I guess a better question: how could you have even set them up without the control center first? Remember that if the SMG scanners are geographically Not on the same site, it is highly recommended to have separate control centers! Why, if the wan links are too slow, the control center monitoring / controlling a far away scanner will see unpredictable results. Minimum 1 gigabit connection from scanner to control center. That way you a have a reliable and fast response.
