There are a few ways to accomplish what you want. For me, I use LANnouncer which requires an Android device with at least 5.1 Lollipop OS along with a smart App called BigTalker. I personally feel that this is the nicest option and can creates the most pleasant sounding chimes when doors and windows open. I don’t think you can use your existing alarm to create short beeps. There is another type of alarm that will allow that listed below. Finally, if you search for “Door chimes”, you will see a lot of discussion on this topic.
There is also this but it uses a different kind of alarm (Aeon Siren). All of this requires some knowledge of adding custom Device Handlers (DH) and installing community provided smart apps. It may seem intimidating at first so take it one step at a time. It’s really not too hard once you have a basic understanding of how things work plus there are plenty in this forum who will be glad to help you out along the way.
