Red Light

What does a flashing red light on the side of a listed building?
Leaving work, I noticed a flashing red light on the part of the building, near the door. The fire alarm / alarm Security does not even have disarmed to see if the light stops flashing, but it did not. The light seems to have been established in the building instead of being connected after construction. It seems that some of its cash standard, but you do not know what that means.
This may mean something, so it's probably best to consult your safety equipment. One thing that comes to mind which could indicate a door is opened. In the basement of my building there are many buying traffic, including golf carts that are used to move around. An office with a door in the hallway with a light on top, so when the door opens, flashes of light, and each person entering the desire to know that someone leaves the door for them to be careful not to get ahead. The light near the door of the building may serve a similar purpose.
