Abstract

An evacuation assistance apparatus for indicating a route within a building or other structure is disclosed. Multiple housings contain laser light line sources for producing a beam of laser light as a linear line. Adjusters are used to alter the laser light line so that the line starts substantially vertically below said housing. The adjusters also allow the line to be directed on to a portion of the wall to highlight an exit doorway. The apparatus is provided as a modular system including multiple sensors making it suitable for installation in many buildings and providing feedback information to prevent or determine the cause of a fire.
