Ring Alarm Contact Sensor (2nd Gen)

We snagged a 8-piece gen 2 home security kit for $60 from a neighbor and we ended up needing more sensors for the windows. Glad this comes in a larger pack than 2! All sensors work as expected, easy install: just scan the qr code which is easily available on the packaging under each sensor & stick the device where you want.

Very difficult to open if you wish to use a screw in side to mount it on doors at time you have to use a screw to stop from opening if you mount wrong you can not use over will not work and no replacement sticky pads you have to send the sensors back some doors and windows this will not work you have to be very creative a door like this picture will not work well so i have to cut the trim a bit and not all windows well they work get the glass sensors much nicer

Compré este como reemplazo porque el que venía con mi sistema de seguridad ring me consumía las baterías en menos de tres semanas. Hasta ahora va bien y funciona como debe.

The ring alarm system is amazing. These sensors are easy to install and just as easy to learn. The tech support is great, i had a doa sensor and they replaced with no problem.

I currently have 3 of these contact sensors in use with my hubitat elevation z-wave network. They were easy to initialize.
I’ve had a few rare occasions when the system didn’t respond to a door opening. I cannot say whether those were due to the contact sensors, as i never checked the logs.

I like them and will buy more.

(i painted one flat black to match my front door.)

Works as it should no issues

Just pull the plastic tab off the battery and the adhesive covering off the back and place it where it needs to be and your food! My system picked up a new sensor automatically. Can be placed end to end or at an angle (like i had to in the picture)

Original review below. Since then, ring has contacted me and is sending me the 2 replacement contact alarms. Assuming these new ones aren’t defective, i really have no reason to give them any less than 5 stars. Good job with the customer service.

I bought the entire alarm system last year. The contact alarms that are made for you doors and windows go out quickly.

I currently have 4 of them in my house. 2 of them no longer work. The ones that don’t work are indoors and keep dying even after i add new batteries to them.

It sucks because i like everything else about ring, but now i might have to go with a company that won’t send me defective products.

The product is being used for property protection. I am replacing an older security system and the sensors were the last components. Every window and door, to include the garage overhead and pedestrian are now monitored. Activation notifications are prompt and the overall system has adequate technical support. The sensors are easily installed. The batteries are readily available at most stores and last a long time.

Excellent so far.

I bought this to have complete coverage in my house, one sensor constantly drains the batteries and i have to replace every month or so. No other sensor has this issue. Did all the troubleshooting steps and still wasn’t working. I chatted with support and they couldn’t do anything so had me call them and waited 15 minutes on hold. I pray for the protect plus plan which includes extended warranty… Can’t get the $20 sensor rma’d which is ridiculous for a security company. Ended up having to pay off of pocket and buy a new one.

Update- i received a message from ring customer support to resolve this issue and after working with melissa, she got my broken contact sensor rma’d and new one is on its way. Updating to 4 stars, would be 5 if i didn’t have to go through that much to get it fixed under warranty.

It always seems there’s one out of the package that doesn’t work.

Overall these are functional as ring sensors which is their main job. The main complaint i have centers around how easily these can be opened. The previous model required pressing a button to open the sensor and we’re quite hard to tamper on accident. These on the other hand practically slide apart if you as much as touch them. This caused me to have to remount some of the sensors since the sensor and magnet would touch when the door was closed hard, something that wasn’t a problem with the 1st gen sensors but something that causes these sensors to fly open and report tamper.

Good product

One bad sensor out of the box, it gave a tamper error that wouldn’t go away. Ring support sent a new sensor. Otherwise, sensors are relatively easy to install. Kits do not come with mounting screws. I used #6 x 1/2′ wood screws to mount the sensors to doors and windows. On one of my entry doors, i had to work around the molding with a wood chisel which was one of the tedious installs.

These are very easy to install and work well.

For the vast majority of windows and doors, this works very well. The only exception i found is some windows in the finished basement that have a tight frame (<1/8 inch of clearance) around the window and open inward. There is no way to attach the two parts where they will not be in the way of each other, preventing the window from opening. I had to install a motion sensor in those rooms instead.

The ring alarm contact sensor alerts me when a main door opens without fail. The installation of the sensors on windows was much easier than on the doors. One main issue is a piece of trim, a part of a sidelight, that prevents the door from lining up properly for an easy sensor install. If y’all are having a similar issue, you might want to try this simple solution. I found that the adhesive strips lost the adhesive quickly, due to my continuous removing & replacing the sensor components, trying to find a suitable spot. I tested each spot to see if there was enough contact area to sound the alarm when i opened the door. Needless to say, this process was was tedious, time consuming, and infuriating! After considering several other options, including cutting notches in the trim, ( i was that desperate), i thought about those 3m picture hanging strips and they just might provide the extra lift to bring the contact area up enough to sound the alert. Hey, what would it hurt? Success! It worked! I did have to cut some strips to fit the components, but that was not a problem. The best part of this solution is that i didn’t mangle the trim and the sensor can be easily removed and replaced for painting or if we ever move to another house. I hope the majority of y’all won’t ever need these directions. I am giving this product good ratings based on the install on windows and deducting 1 star for my door situation. Fyi, i’ve used the non-picture 3m strips to secure the alarm keypads. I’ll post pix/video later today/

Too expensive compared to other contacct sensors but they are the only ones you can use with the ring system. They got you!
