Fire detection and fire alarm systems. Fire alarm devices. Visual alarm devices (British Standard)

This European Standard 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 (see item C of Figure 1 of EN 54-1:1996). 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 European Standard specifies the evaluation of conformity and the marking of the visual alarm devices.

This European Standard applies to visual alarm devices that rely on software for their operation and to those that do not.

This European Standard applies only to pulsing or flashing visual alarm devices, for example xenon beacons or rotating beacons. Devices giving continuous light output are excluded from this European Standard.

This European Standard is not intended to cover visual indicators, for example those on detectors or on the control and indicating equipment.
