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 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 (PAGA) 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.
