Emergency escape route signalling system - with spaced indicators along route illuminated in succession

摘要

The spaced indicators, which may be in the form of arrows, are positioned at spaced points along the route and are successively illuminated with a predetermined phase lag between the, so as to give the impression of a light moving along the direction of the route. The colour of the indicators and/or the intensity of light emitted and/or the rate at which the indicator is illuminated increases as the end of the escape route is approached. The indicators are preferably each associated with a supply sourced and can be actuated by remote control, in response to the release of an alarm circuit.
