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.
