Over deze norm
This part of ISO 7240 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 a fire detection and 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 part of ISO 7240 specifies visual alarm devices for two types of application environment, Type A, generally for indoor use, and B, generally for outdoor use and Type C for use in harsh environments such as mining. This part of ISO 7240 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 part of ISO 7240 . This part of ISO 7240 is not intended to cover visual indicators, for example, on detectors or on the control and indicating equipment.
