ABSTRACT:
Apparatus for identifying and directing attention to a location, such as an emergency exit, includes a series of sound generators arranged along a path leading from a remote site to the location. The sound generators are energized sequentially and individually, preferably with a tone which rises in frequency as the sound travels from the remote site to the location of interest. If the sound generators are used to direct attention to an emergency exit, the sound generators are activated upon the occurrence of an emergency condition, such as a fire, and the sequence of tones is cycled continuously until the emergency condition ceases.
