AFAIK the ring siren was discontinued in the states because it resembled another security company’s logo, or whatever. I’m in the UK, but I’d suggest the redesign show some synergy across products. I particularly like how the base station LED looks, and think it would look pretty cool as an exterior siren/indicator, instead of that terrible blue.
Picture is attached for reference.
An outdoor (weatherproof) loud siren is needed as a Ring Security addition. It needs to be fully intergrated with ability to change siren audio, contol its function, etc.
I was going to but the interial siren but based on the reviews and lack of rich intergration and audible levels, I skipped.
Maybe use the Chimes an an alert device?
Maybe use connected Alexa devices as indoor Siren’s and alarm count down audio devices.
Unfortunately, the Ring Alarm system can only currently activate the sirens on the Alarm Base Station, and Keypads, and the indoor non-weather-resistant Dome Siren. 
But you aren’t alone in wanting an external siren! Many others want an outdoor weather-resistant siren, or some ability to connect an exterior siren, or some way to have a siren sound outdoors . The more “Thumbs Up” Kudo votes they see there will better get their attention, increasing the chances of getting siren sounds outdoors.

Hello @Brumey ,
Although this is not a “Stand-alone” outdoor siren, Ring has listened to all the Kudo votes on the numerous “Feature Request” board and the camera sirens can also now be linked to the Alarm Base Station siren! So now when the Alarm Base Station siren goes off, the Ring cameras (that have siren feature) can also automatically sound off with their siren!
So, I immediately went to my Ring App to link mine also! But, I was briefly disappointed when I tried to do it because I did not initially see any change in the App. It initially appeared to still only make the cameras record when the alarm sounded . . . until I looked more closely. So, yes, the camera sirens CAN be linked now by:
After selecting “Alarm Sounding”, this is where I was briefly disappointed because I thought it was still just to select the cameras to only record. Then I noticed the “Explanation-Point” Icon, just right of the “Camera” Icon. Now I understood that by selecting this “Explanation-Point” Icon, it links the camera’s siren to the alarm too! So after selecting “Alarm Sounding” then:
Wonderful! Thank you Ring! 
Yep, being a UK user and fully invested in the Ring ecosystem, this is a massive game changer for me.
Incredibly happy that I can now have multiple internal and external sirens in the event of a break-in.
We are considering the Ring alarm system to compliment our numerous Ring cams over our large property, but only if detected motion will trigger one or more of the floodlight sirens. After reading your detailed remarks, I called Ring ‘product specialist (Tiffany)’ who said she was not aware of this new added feature. Aghhh, I hope you are correct and she just didn’t get the memo. Is there any more info to link to this new feature? Thanks.
See screenshot from app. I have 11 internal/external linked devices set up to sound sirens when the alarm system sounds!
Hello
I cant seem to find the alarm modes in the siren setting so i make it work only when away and not home armed mode
what happened to the outdoor siren in the US?
The one thing holding me back from buying a Ring alarm for my primary home is the ugly (imho) stop sign shaped blue branded siren. Perhaps some people like it, and I understand that it’s also free advertising for Ring, but as a consumer, appearances and security by obscurity have higher priorities. A generic looking outdoor siren with a red light would be ideal. Burglars won’t be immediately aware of the weaknesses and strengths of the alarm system in that case and probably err on the side of caution (e.g. won’t try using a mobile network and WiFi jammer).
I’ve searched for other brand “works with Ring” outdoor sirens but haven’t been able to find one yet.
when will ring bring back an outdoor siren? they offer it outside the usa? sounds like ADT sued them so they stopped offering in the USA. thats pretty weak. Ring: please come up with an outdoor siren that does not look like ADT’s logo and release it already!
Hi neighbors. The Outdoor Siren for the Ring Alarm is discontinued and not available for purchase in the United States and Canada. It is still available in the UK at this time. We currently do not have any information on when a new Outdoor Siren will be available. Thank you for your continued feedback on this.
Hi. I found a way to add a loud outdoor siren to the Ring Alarm and thought I would share it. First you’ll need the Ring Outdoor Smart Plug (and bridge). Once you install it, go to the base station and add this as a linked device. Then set it to “turn on lights” when the alarm is sounding.
You’ll then have a power source that will turn on when the alarm sounds and then off when the alarm stops sounding (I’ve noticed a delay of about 10 seconds after the alarm is disarmed before it actually turns off). I plugged a 12V DC Constant Voltage Transformer Driver to this in order to power a 12V DC siren as well as a LED strobe lights. However you can use it as you like.

Please provide link to siren you purchased. Thanks!
As I understand it, this product was discontinued in NA some time ago due to a patent issue with the design of the face plate. It would seem to me that a simple redesign of the face plate could be accomplished in a short period of time and at minimal cost to make this product available in NA.
I too was disappointed upon learning that Ring didn’t have an outdoor siren in the US due to a copyright dispute with another vendor. I think it had something to do with the shape of the device. I don’t see why Ring can’t just produce a round external siren…since a “Ring” is round anyway.
I replaced my old wired perimeter system with a new Ring system.
So…putting my electronic skills to use, I assembled a work around outdoor siren and strobe using a Ring dome siren as a trigger device integrated with an external timing module and a 12 vdc power supply. I also added a manual override switch to bypass the Ring dome siren in the event of a low battery condition in the Ring dome siren or a software issue.
If Ring finally produces an outdoor siren in the US, I will still be able to use the dome siren separately.
Indeed, just a different shape should suffice?!
Hoping this does still come out again! Thank you!
Bumping this topic. Any plans to get an outdoor siren update that will work in the US? Or does Ring just not care?
I’ve tried to get Ring to answer this question as well but unfortunately get a canned response from Ring reps about the siren being discontinued. How is it possible that a company that specializes in alarm systems, doesn’t have a product that is central to the effectiveness of alarm systems; a loud outdoor siren? It seems like pretty low-hanging fruit to develop such a product so I’m wondering why Ring has chosen not to do so.
