What is BS EN 54-23 – Fire visual alarm devices  about?

BS EN 54 is a European Standard on fire detection and fire alarm systems. It aims to establish operationally efficient safety equipment and systems that play a positive role during a fire emergency. BS EN 54-23 is the 23 rd part of the multi-series that specifies the requirements, test methods, and performance criteria for visual alarm devices in a fixed installation intended to signal a visual warning of fire between the fire detection and fire alarm system and the occupants. BS EN 54-23 is intended to cover only those devices which derive their operating power by means of a physical electrical connection to an external source such as a fire alarm system. BS -23 applies only to pulsing or flashing visual alarm devices, for example, xenon beacons or rotating beacons. BS -23 is not intended to cover visual indicators, for example, those on detectors or on the control and indicating equipment.
