BS EN 54-23:2010 Fire detection and fire alarm systems. Fire alarm devices. Visual alarm devices
BS EN 54-23 is a European Standard which specifies the requirements, test methods and performance criteria for visual alarm devices in a fixed installation intended to signal a visual warning of a fire between the fire detection and fire alarm system and the occupants of a building.
It 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 EN 54-23 specifies the evaluation of conformity and the marking of the visual alarm devices.
BS EN 54-23 applies only to pulsing or flashing visual alarm devices, for example xenon beacons or rotating beacons. Devices giving continuous light output are excluded.
BS EN 54-23 is not intended to cover visual indicators, for example those on detectors or on the control and indicating equipment.
