Adding a new beacon

Hi, probably a silly question. I have setup one beacon to work with an ios app using the template and all is working fine I now want to setup a second beacon that will do exactly the same as the other beacon. eg just placed in a different room. However, when I logged into the admin area and I selected the same tags as the other beacon but the second beacon is not getting triggered? is there something else you need to do? or does it take a while to sync?
