Voice alert systems are used throughout the London Underground, so its perhaps fitting that one is now being used at the London Transport Museum in Covent Garden. A blend of wall and bracket mounted Vimpex Fire-Cryer speakers are being used to ensure clarity of information during emergency situations. 'Unambiguous' messages are designed to eliminate confusion for both staff and public. Vimpex says the popularity of its technology for public premises is driven by an understanding that provision of a guiding voice is more effective at evacuating a building, compared to sound alone. It claims the units need no special wiring and can be integrated with existing systems. They can be fully synchronised and have a low current consumption, allowing simple replacement of existing sounders and bells. The multi-message capability also ensures that 'system test' and 'all clear' messages can be easily transmitted, avoiding confusion with a fire/evacuation alarm.
