BM 3804

DESK-TOP PAGING MICROPHONE

BM 3804

BM 3804 is a desktop paging microphone exclusively dedicated for the RCF DXT 3000 system. It can be directly connected to the MX 3250 main unit through a fourpair J-type fire-rated cable.
Up to four BM 3804 paging microphones (interlocked one another) can be linked (daisy-chained) to the line. The first BM 3804 paging microphone (of the line) is directly powered by the MX 3250 main unit, while the second, the third and the fourth need 24 V dc adapters (500 mA, i.e. RCF AC AD 2405, optional).
