ME 3801 is a wall mount emergency microphone exclusively dedicated for the RCF DXT 3000 system. It can be directly connected to the main unit through a fourpair J-type fire-rated cable. If more than one microphone is connected to the system (interlocked one another), in daisy-chained link, ME 3801 shall be the first one, configured as emergency microphone and directly powered by the main unit, while the second, the third and the fourth need 24 V DC adapters (500 mA, i.e. RCF AC AD 2405, optional).
