Description
The VAP30 is a heavy-duty indoor microphone unit designed to allow public address/paging system. The VAP30 can be supplied certified to provide safe operation in potentially explosive atmospheres and is ATEX & IECEx approved accordingly. The VAP30 comprises of a robust steel enclosure, which is equipped with an industrial operator membrane keypad and hyper-cardioid noise cancelling microphone fitted to a flexible gooseneck stem. The operator keypad array is specially designed to provide tactile feed back to the user and ergonomic layout. Large sized of keys according to operational importance simplifies paging and alarm (PA/GA) system operation.
Duplicated status LED’s are fitted to indicate the availability of control command by the central equipment. For ultimate integrity the unit is available with two independent microphone transducers, which can be arranged to each drive dedicated amplification and loudspeaker arrays. For dual circuit execution, two VAP100 series processor/pre-amplifier modules are fitted to obviate common mode failure possibility, which are serviceable on a plug in/out basis. In highly critical life safety applications Emergency Direct Connection (EDC) is fitted as standard on VAP100d processors. This allows the host amplification to be controlled independently of the data processing sub-system/data transportation protocol. The VAP30 can be equipped with up to two conventional push button actuators which are independently wired to the central equipment, these allow selection of project specific special requirements. The VAP30 is equipped with a high performance VAP100 line driver that enables the unit to be located remotely from the host loudspeaker amplification. Automatic monitoring is included to supervise microphone voice coil, pre-amplification and critical paths to the central equipment. The VAP30 requires no local mains supply, the unit is energised by phantom power sourced from the host central equipment panel. Connectivity to the unit depends on which VAP100 transceiver type is fitted.
