Question:

If it's not a smoke detector, what is it?

My dorm has smoke detectors in every room, hallway, etc. There's one in the laundry room too, but there's also something else on the celing and i'm not sure what it is. It's like disc shaped and in the middle it sticks out a little and it covered by a white cap. You can also see a blinking red light under the cap. Any idea what this is

Because church steeples are often the tallest structures in an area, and therefore the most likely to get struck by lightning. So, they ground the steeple with a lightning rod so that when it is struck, it won't catch fire.
