Xfinity Home Error message 11724

I received a message on the display pad that the battery was low in one of the door sensors. When I replaced the battery, it caused an error with that sensor's communications with the security system.

Now, my Xfinity Home alarm keeps making the open/close door sound every 15 minutes or so and whenever I try to arm my system with that zone acitve, I get error message 11724.

Any help or feedback would hbe greatly appreciated.
