How do fire doors work?
Fire doors are used to stop fires or smoke from spreading into different areas of a building. Some fire doors have furry strips round the edges, these are called intumescent strips. The fibres in the strips swell when they get hot and stop smoke going round the edges of the door. The doors themselves are made up of layers of fireproof material which means that it takes longer to burn through the door. Most common fire doors protect the rest of the building for around half an hour only because of the intsumescent strips and the fireproof material actually on the doors.

What happens to automatic doors when a fire alarm is activated?
Automatic door systems and the fire alarm systems are linked together. Automatic doors are held open by strong magnetic type devices, that are activated(turned on) during normal activity. When the alarm is activated, the devices are shut off and the doors close. These doors are programmed to close in an effort to keep smoke and flames from spreading too far(these doors are usually strongly fire resistant.) Once the alarm is shut off/reset, the devices will be activated again and will remain open once somebody opens the doors back up. Another type of "automatic door" is a fire door that slams shut (springs, counterbalances, gravity, etc) when the heat-sensitive link melts, or when a fire alarm is activated. These heavy doors are NOT intended to be opened during a fire for means of escape, so there must be other doors accessible for people to escape the area safely.
Why is it a good fire precaution to close doors at night?
Because closing doors can slow down the smoke and fire, giving occupants more time to react to a smoke alarm or other fire alarm. If doors are open, the hot smoke and gases can spread by convection and radiation faster than by conduction of heat through the door or wall.
