## Customer Reviews

### ⭐⭐⭐⭐⭐ Ideal for old alarm to RING alarm conversions. See photos:
*by K***. on June 17, 2020*

This j4home was just the adapter that was needed to allow for hookup of a new 2nd Gen RING alarm system in place of an old hardwired ADT system. The RING package comes with a standard outlet wired plug and as a result, clean wall mount installation is not possible. This adapter allows to power the RING alarm from the two (red and black) power wires that were used for my old setup. One side is the red and black wires which join to the red and black wires on the old alarm setup and the other side is the RING jack. It installs easily and functions perfectly. I attached pictures for reference. I now have a seamless, wire free wall mount on my RING alarm and had no issues with the adapter not fitting or being a different size with this Gen 2 module. Good luck.

### ⭐⭐⭐⭐⭐ Easy to install and works flawlessly
*by G***G on July 22, 2024*

Power supply to Ring keypad

### ⭐⭐⭐⭐⭐ Work perfect
*by J***L on May 31, 2024*

Use this for power to my Ring alarm system in 12v. Converse-sko 12v to 5v and work perfect.
