    • A must have if you’re replacing an old wired alarm with a Ring alarm
Configuration: Ring Retrofit Alarm Kit
This diminutive gadget (it’s roughly the size of a stack of 4 CD jewel cases) is designed to allow you to integrate legacy sensors from an existing old alarm system into a Ring wireless alarm system. It attaches to the Ring base wirelessly, a very simple process; and then you can connect the sensor wires to its terminals, it supports up to 8 zones. For more zones, you can add more extenders. Door and window sensors do not require any special treatment, but motion and smoke detectors will require a 12V supply with battery backup. I found an inexpensive 12V UPS that is perfect for this, although the problem is when it fails it will trigger the alarm... The huge benefit of this device, though, is that it lets you use all the existing wired sensors: no running wires, no batteries, no problem (well, the batteries in the extender) Setup is super simple thanks to the well designed app. Go to the Devices section, select the extender, and you will see all the ones. Any zone with a sensor connected is configurable, the others are grayed out. To configure a zone, you select it and then open and close the door or window; you can then name and save the zone, and it becomes enabled. Couldn’t be simpler. Very well designed device, great software, if you’re contemplating Ring and your house has an existing wired alarm system don’t hesitate, make sure you buy this extender. It’s a little pricey but worth it. Buy Ring motion detectors and use your existing door and window sensors! Very highly recommended. ... show more

    • Either hire a professional or be prepared to learn about the wired alarm system in your house.
Configuration: Ring Retrofit Alarm Kit
I couldn’t resist the opportunity to dig into the rats nest of wires in the closet of my 75-year-old house. As I did this, it became clear to me that the alarm system I was replacing (ADT) wasn’t the original. There was a lot of wiring left over from an even earlier alarm system. The one I was replacing also had only eight wired channels and relied on wireless for the rest of the motion detectors and door and window sensors. However, some earlier wired alarm system clearly had many more than eight channels, and I found myself wishing that this retrofit kit could accommodate more than eight of them (you can buy more than one of these to get more channels, but that’s expensive). However, it was easy to set this retrofit kit up so that two or more wired door and window sensors are wired in serial on the same channel, so that any of them being open will be registered as an open signal. This allowed me to take advantage of all of my house’s existing wiring, with a disadvantage that if a channel is giving an “open” signal I’ll have to try two or three windows to figure out which one is at fault. Other than my frustration at this device not having says 16 or 32 channels, it’s fine, pretty straightforward to use, and offers the presumably greater reliability of wired sensors. Will it save you any money? Not really, the ring door and window sensors are inexpensive (especially when on sale), and this item never seems to go on sale, meaning that on balance you might be better off just going to a completely wireless system. The only reason I didn’t go that route is that I felt that a wired se sensors waere probably going to be more reliable and it reduced the number of visible (and to my eye slightly unsightly) sensors that I had to install. ... show more

The Ring Retrofit Alarm Kit is perfect for our needs and was much easier to install and configure than I expected. You do need to be comfortable with electrical wiring although the connections are all low voltage. We built our home 3 years ago and had a Honeywell system installed with every window and door monitored with hardwire contacts. I did not want to have to routinely replace batteries in battery operated contacts. You will need to remove the Zoned wires attached to your current wired alarm system one by one, test them with a continuity tester and connect them to the Retrofit Kit. I found that we had more than one (sometimes 5) windows and/or doors wired in series before they were connected to our Honeywell alarm circuit board. I had previously labeled all the zones which made it a bit easier but you still need to verify all windows and doors in a zone using the Ring app during installation, which I found very easy. I added 22 gage extension cables to each zone in the Honeywell box so the 15 plus zone cables stayed in the Honeywell alarm box and only 6 cable were routed out to the Retrofit Kit. After installation, which included 3 of the Ring 2nd gen keypads (to replace the Honeywell keypads), a Ring Motion sensor to replace the wired sensor and 1 Ring Contact sensor to replace the battery contact on our patio slider, I discovered there was a lot of flexibility to defining zones, which zones armed when in Stay mode and with armed in Away mode. Very please with the flexibility of the Ring Alarm and Retrofit Kit. Ring monitoring and very reasonable compared to local monitoring companies. Ring alarm can be configured with Alexa which will monitor your smoke detectors and glass breaking (using Alexa Guard). Arming and disarming can be done by key pad, the Ring phone app or Alexa. ... show more
