1. An intelligent directional emergency alarm system for a building having at least first and second areas to be protected, said alarm system comprising:

  • (a) a plurality of threat sensing nodes, at least one threat sensing node located in each of at least first and second areas of a building, each of said plurality of threat sensing nodes responsive to detection of a threat, for generating a warning signal representing said threat, said warning signal including an indication of which threat sensing node is generating said warning signal;

    (b) a plurality of directional lighting modules, each directional lighting module having a plurality of light sources in a linear arrangement, said linear arrangement having a first end and a second end, and configured for receiving a directional lighting module activation signal for causing said plurality of light sources to illuminate in a predetermined arrangement;

    (c) at least one microprocessor based control module, coupled to said plurality of threat sensing nodes, and configured for receiving said warning signal and for generating a control module report signal in response to said warning signals, wherein said control module report signal is based on said received warning signals from all threat sensing nodes in all areas of said building, and wherein in preparing said control module report signal, said microprocessor based control module is configured for accessing previously stored information including a physical location of each threat sensing node, physical location of each exit in a building and physical relationship of each threat sensing node vis-à

    -vis each building exit; and

    (d) a plurality of indicator units, each of said plurality of indicator units coupled to one or more directional lighting modules, each indicator unit responsive to said control module report signal, and configured for selectively activating each of said plurality of connected directional lighting modules based on reception of said warning signal and said control module report signal, so as to indicate a specific direction away from the threat through a sequential illumination of each of said plurality of light sources in order from said first end of the linear arrangement to said second end of the linear arrangement or from said second end of the linear arrangement to said first end of the linear arrangement to ensure evacuees are moving away from all threats in all areas of said building using one or more predetermined exits as determined by said microprocessor based control module.
