Abstract: An emergency alarm and evacuation system for directing persons to an emergency exit. The system includes an alarm, a plurality of indicator units arranged in a line toward the emergency exit, and an operating unit coupled to the alarm and being operable in response to an output signal from the alarm to successively energize the indicator units in the direction of the exit. The indicator units each have a light and a buzzer so as to generate both an audible and visual indication at a common point whereby persons may be guided by the sounds, the visual indications, or both, depending upon the smoke or noise conditions.
