scope:

This European Standard specifies the requirements, test methods and performance criteria for visual alarms in a fixed installation intended to signal a visual warning of fire between a 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.
This standard specifies visual alarms for two types of application environment, type A for indoor and type B for outdoor use.
This standard is not intended to cover visual indicators, for example, on detectors or on the control and indicating equipment.
This standard applies only to pulsing or flashing visual alarms, for example xenon beacons or rotating beacons. Devices giving continuous light output are excluded.
