What factors should I consider when using an external power supply with a Gemini control panel?
We recommend that you consider an external power supply for your system if the power draw is close to the maximum allowed by the control panel.
When using an external power supply, be sure to provide a common ground wire that runs from the power supply DC negative terminal to the keypad bus ground / negative terminal. This electrically connects the panel and external power supplies to avoid data failures between bus devices, i.e., keypads, StarLink communicators, EZM expansion zone modules, etc.
