TOA System at Natural History Museum

TOA voice alarm equipment features prominently in a rolling development programme at London's Natural History Museum which is currently being carried out by Static Systems Group plc. Presently the installation utilises three TOA equipment racks, plugged with V series amplification and processing. Each fire alarm fully communicates with the voice alarm, which sends out a common PA message. Destinations can be selected and the system will link the fireman's mic and broadcast to any PA zone via a touch-screen and Static Systems' proprietary TDM (Time Division Multiplex). The AMX front-end touch screens were supplied by TOA, to provide a visual switching and a map of the museum for paging and message broadcast purpose (messages are pre-recorded and stored using TOA's EV digital message machines). While much of the system is connected to standard loudspeakers, TOA F-777s are found in the main entrance hall, F-505s on the stairs and F-10Bs in the alcoves and balcony, each controlled via TOA's DP-0204 digital signal processors. Eventually, TOA expects eight racks to be commissioned, connecting areas such as the Earth Galleries, Whale Hall and Darwin Centre through the control rack in the Central Hall of the Waterhouse Building.
