Egress direction indication system
First Claim
1. An egress direction indication system comprising:
- an indicator unit including at least three electroluminescent lamps in a linear arrangement;
a first means when activated for sequentially illuminating at spaced intervals to indicate a specific direction said at least three electroluminescent lamps in order from a first end of the linear arrangement to a second end of the linear arrangement;
a second means responsive to the illumination of the electroluminescent lamp nearest said second end for extinguishing all said electroluminescent lamps in the linear arrangement simultaneously; and
a third means responsive to the extinguishment of all the electroluminescent lamps in the linear arrangement for activating said first means.

Abstract
An egress detection system includes an indicator unit having at least three electroluminescent lamps in a linear arrangement and circuitry for sequentially illuminating the electroluminescent lamps on a repeated basis in order from one end of the linear arrangement to the other end of the linear arrangement. The indicator unit includes a plastic extruded panel containing a circuit board on which the electroluminescent lamps are mounted, and a lens covering the electroluminescent lamps and bonded to the panel. The panel includes an electrical connector which allows the panel to be removed from the electronic circuitry and replaced. The electronic circuitry is also provided to sequentially illuminate a group of electroluminescent lamps in one direction in response to a first sensed condition of relative danger and in another direction in response to a second sensed condition of relative danger.

7. An egress direction indication system comprising:
-
a plurality of indicator units, each indicator unit including at least three electroluminescent lamps in a linear arrangement; a first means when activated for sequentially illuminating at spaced intervals to indicate a specific direction said at least three electroluminescent lamps in order from a first end of the linear arrangement to a second end of the linear arrangement;
a second means responsive to the illumination of the electroluminescent lamp nearest said second end for extinguishing all said electroluminescent lamps in the linear arrangement simultaneously;
a third means responsive to the extinguishment of all the electroluminescent lamps in the linear arrangement for activating said first means; andeach indicator unit being mounted on a wall and spaced from adjacent indicator units;
a first indicator unit being positioned near a point of egress and oriented so that the linear arrangement of its lamps are sequentially illuminated in the direction of the point of egress; and
at least one other indicator unit being oriented so that the linear arrangement of its lamps are sequentially illuminated in the direction of the first indicator unit. - View Dependent Claims (8, 9, 10)

11. An egress direction indication system comprising:
-
an indicator unit including at least three electroluminescent lamps in the linear arrangement; a first means when activated for sequentially illuminating at spaced intervals to indicate a specific direction at least three of said electroluminescent lamps in order from a first end of the linear arrangement to a second end of the linear arrangement in response to a first sensed condition of relative danger at the first end;
a second means when activated for sequentially illuminating at spaced intervals to indicate a specific direction at least three of said electroluminescent lamps in order from the second end to the first end in response to a second sensed condition of relative danger at the second end;
a third means responsive to the illumination of the at least three of said electroluminescent lamps in the linear arrangement for extinguishing all the electroluminescent lamps in the linear arrangement simultaneously; and
a fourth means responsive to the extinguishment of all the electroluminescent lamps in the linear arrangement for activating one of said first and said second means in accordance with a respective first and second sensed condition, thereby directing egress away from the area of relative danger. - View Dependent Claims (12)

23. An egress direction indication system, comprising:
-
a plurality of indicator units including a master indicator unit and at least one slave indicator unit, each slave unit being electrically connected to the master unit, each master unit and slave unit having its own battery power supply so that each unit is failsafe and the failure of one unit will not prevent the other units from operating, each indicator unit including at least three electroluminescent lamps in a linear arrangement; means for sequentially illuminating said at least three electroluminescent lamps on a repeated basis in order from one end of the linear arrangement to the other end of the linear arrangement;
each indicator unit being mounted on a wall and spaced from adjacent indicator units;
a first indicator unit positioned near a point of egress and oriented so that the linear arrangement of its lamps are sequentially illuminated in the direction of the point of egress, and at least one other indicator unit being oriented so that the linear arrangement of its lamps are sequentially illuminated in the direction of the first indicator unit; andmeans in said master indicator unit for actuating the illuminating means in the master indicator unit and said at least one slave indicator unit. - View Dependent Claims (24)
