I currently looking for alternative options to power my wall mounted tablet. (I really DONT want a 120V outlet above my keypad even if its recessed/hidden).
Option 1: I currently have a working Vista 20P alarm system with 2 keypads (Amdenco 6139).The keypad is powered from the alarm system (vista 20P). I want to install my tablet direct above my keypad. I was wondering If I could wire a 12v to 5v adapter direct to the working keypad. Please note, Im keeping the keypad working. Im still trying to find what the MAX output amps on this is. I have the supplemental Power attached but IDK if that applies to the keypads or not. I was hoping since this was a popular panel someone might know.
Option 2: I do have a single pole light switch near by and was thinking of an inline 120V to 5v-usb and from the just need a small wire up to the tablet. Anyone have suggest on this way? (or links to these?) I found one. I would like to “hide” the converter(step down transformer) in the gangbox with the switch.
Thanks!!
You can see many examples of what other people have done for powering their control panel projects in the following thread:
If you want even more, or want to look at just one at a time, you can find individual project reports by looking on the quick browse lists in the community-created wiki, looking down near the bottom of that page for the “project reports“ section , and then choosing the “dashboard“ list.
