Bring existing wired contact sensors into a modern wireless security ecosystem with the Ring Retrofit Alarm Kit. This wired-to-wireless bridge from Ring enables businesses and property managers to convert up to 8 existing wired zones into fully monitored wireless zones on a Ring Alarm Base Station, letting you centralize alarm, surveillance and monitoring in the Ring app. The compact indoor unit (4.53" x 4.53" x 1.0") runs on two lithium batteries (included) and supports both wired and wireless connectivity, minimizing costly sensor replacements while preserving site investment.

Once installed, doors and windows connected to the Retrofit Alarm Kit function like native Ring sensors — send mobile notifications, arm/disarm from the app, and view events alongside Ring Video Doorbells and cameras for unified situational awareness.
