The number of Controller Doors
For broader application, the number of manageable doors can be changed for some controller models. The less the door to be managed, the more the input/output can be used. For details, please refer to user manual. In case neither the doors manageable nor the number of input/output are sufficient, user may consider using other controller models. Additionally, for some models, extension board can be used to increase input/output.

Notice: If user change the number of controller doors, it will loss original controller all setup.
