So the much anticipated (at least by me) Ring Retrofit Alarm kit has turned out to be a huge disappointment. It is up on Amazon for pre-order and will ship on Dec. 11th. I was eager to see how this integrated into an existing alarm, so I downloaded the .pdf manual for it.
Gleaned from the manual is the fact it really does not integrate with an existing alarm system. At least that is what I believe after reading the install manual, attached to this post. The retrofit kit only allows 8 zones, that use 2-wire (not 4) sensors that essentially are door/window sensors and little else. You need to physically remove the wires for the sensors you want to integrate from the old alarm system, and connect them to the retrofit kit. This is not what I was expecting. I ASSUMED that it would translate the codes like an Alula device would, and transmit that info to the Ring Alarm. Wow, big, wrong assumption.
At any rate, I won't be going with this device as it is actually cheaper and cleaner to go with the Alula device, which I will looking into much more. If anyone can discern more about how this can interface with an existing alarm, please post it here.
Honestly, for the types of wired sensors it will handle, you are better off just buying the Ring versions. In fact, the Ring alarm already comes with door sensors, so why bother.
