Long time lurker, first time poster. Thanks for having me. We just had a house built and and have sensors running everywhere but no alarm panel. From another post I believe I can use those bare wires with a 12 zone kit without too much trouble.
Can I use the keypad wiring with a 24v 48w transformer (https://www.amazon.com/dp/B0797LGCDP/)to power a tablet and also a video doorbell? The tablet would also have a 24v to 5v step-down behind it as well. The wires probably have about a 25ft run. Thanks for your help.
