8-zone call microphone station compatibile with the T-8000 matrix
The T-8000A is a call station paging microphone connected to the T-8000 matrix via universal CAT5 standard cable for zone calls and communication with remote control boards from different remote locations in the matrix. Each control matrix has 8 x RJ45 sockets for remote control from the call station. CAT5 cabling is used because of cost, ease of installation, but also because it integrates RJ 485 communication, audio transmission and 24 V power supply at the same time. Above 50 m from the matrix a 24 VDC power supply is required.
