Fire Exit Signs, commonly known as exit signs, aid in the emergency egress of building occupants during a fire by providing a lighted version of the word EXIT. Federal, state and local building codes require fire exit signs in all public and commercial facilities. These building codes stipulate the installation locations and placement for fire exit signs throughout the building and the type of fire exit sign that must be installed.

While all fire exit signs are required to be illuminated, not all models require electricity. UL 924 listed fire exit signs are available in AC powered, non-electric self luminous Tritium or photoluminescent models all of which are compliant for use in the United States and Canada.
