Exit path guidance system for personnel evacuation - includes several guidance signs operated by received alarm signal

摘要

The exit guidance system is used to evacuate personnel from a danger zone, in reponse to toxic gases, explosive gases, or smoke etc. being detected. A number of detectors and respective evaluation circuits supply signals to the guidance system, which subsequently energises a series of illuminated guidance signals indicating the appropriate exit route. Pref. each guidance sign has two arrows pointing in opposite directions, either one of which can be illuminated, in dependence on the location of the danger.
