Electric fire safety essay

In some cases, the positive latch required for a fire door will interfere with the desired function of the door.  For example, in a hospital corridor the doors are often equipped with automatic operators, so the preferred operation would be a push/pull function without positive latching.  The Life Safety Code requires fire doors to have a positive latch, but the requirement is addressed in more detail in  NFPA 80 – Standard for Fire Doors and Other Opening Protectives .  NFPA 80 allows fire doors to be equipped with hardware which does not latch each time the door closes, but positively latches upon fire alarm.  This accomplishes the requirements for the fire door to positively latch.
