Hi neighbors! Currently, it is not an option to arm your system with an open Contact Sensor without having to bypass that Sensor. You can utilize the Exit Delay so you have a set amount of time to get out the front door before your system is fully armed. For more information on how to use Entry and Exit Delays, please review this Help Center article.
As Tom mentioned in a previous reply, we do have the Ring Alarm Quick Exit feature available now, which may be helpful in certain scenarios such as taking the trash out or letting a pet into the yard. Regarding the request in the original post, you can find the associated feature request made by the original poster below.
