Lighting Applications - Adaptive Emergency Escape Lighting Systems
Abstract
This document specifies the lighting and operating requirements for the application of adaptive emergency escape lighting systems that can interact with management and control systems or be provided with functionality to modify the operation of emergency escape lighting according to situational requirements, in terms of luminous flux output, escape directions and the characteristics and meaning of emergency escape lighting. The situational requirements can require the involvement and interaction with components and systems other than emergency escape lighting systems. Requirements for these components or systems are not part of this document. The objective of escape route lighting is to assist the safe exit from a location for occupants by providing appropriate visual conditions and direction finding on escape routes by means of a combination of luminaires and signs designed to meet predetermined conditions. Adaptive Emergency Escape Lighting Systems (AEELS) can be used to revise the escape routing and increase the conspicuity of emergency signage depending upon the location of a particular hazard, by using directional exit signs that can be controlled to change routing information and to direct occupants away from an exit route that has become unusable. Adaptive Emergency Escape Lighting Systems can operate in two ways, where signage is changed at the start of the evacuation procedure only, or alternatively where the information displayed by the signs can be changed during the evacuation as circumstances dictate. In this second mode, during an evolving incident, escape routing can be revised using AEELS by using directional exit signs that can be controlled to change routing information directing occupants away from an exit route that has become unusable.
