External power for retrofit kit

My retrofit alarm kit arrived yesterday. I was surprised that the only power option is battery - am I missing something? Since this is going to installed right next to the existing alarm cabinet, there is obviously power available. Is there not an option to tie the retrofit into the existing power?

Yeah, I thought the same thing when I ordered the kit. I’ll bet it’ll be a future upgrade. POE would be a nice option.

Bumping this 2 year old thread because I just installed this and thought the same thing…
What the heck Ring - the wired panel already has AC power + Backup battery. Why not utilize that. Should be so simple. Now I have to deal with replacing the 2 batteries whenever they die.

How long do those batteries last and what type are they? CR???

Hi there, neighbors! As described in the technical specifications for the Alarm Retrofit Kit on Ring.com, the method of power is via 2 X 3V Lithium 123 Batteries ( Included). @JetRocket11, as you asked about the battery use life, these should last 5 years with 100 events per day. “Events” defined as either open/close events or the 70 minute supervisory message sent from the device to the Base Station to report that the device is online.

As the Retrofit Kit is considered to be an advanced DIY solution, the best information will be found within our Community post about the Retrofit Kit.

My batteries on the retrofit lasted 6 months, . I am pretty sure I have less than 1000 events per day to justify such a consumption. 1/ Is there a way to easily quantify the number of events? 2/ Any plans for an external power supply to the retrofit while keeping the battery as a backup?

thx

After I converted my wired alarm system to Ring, I’ve been powering my (2) Retrofit Kits from (2) 12vdc to 3vdc converters that I got on Amazon. Each converts my old alarm system’s 12vdc red/black wires to 3vdc wires that I’ve connected to the Retrofit battery terminals. I’ve removed the lithium 123 batteries. The converter supplies up to 3A which is more than the (2) batteries which supplied .5A each. Be sure to turn off the old alarm’s power while doing the wiring. Connect with the right polarity (+ to + and - to -). Route the wires through the bottom where the sensor wires enter. After powering up the old alarm, test the Retrofit communication (get green light) and close the lid.

Was it just one 3v supply per retrofit module? I ask because the batteries are 3v each — I guess they are wired in parallel?

I just tested … the batteries are in parallel. So if you decide to hardwire the power, you can tie into the connectors for just one battery (and pull both out of the unit).
