6.13.3 Triple antenna system (double aisle)
In case receivers are connected to the transceiver it is of great importance to connect the
FTP and analogue connection cables to the proper connectors on the TRX and RX
boards. Figure 22 shows the connections for a triple system (RX + TRX + RX).
Figure 22: Triple antenna system connections
In this system setup it is important that the FTP cable is connected to the proper bus to
allow for the receiver lights to light up in case of an alarm. The receiver FTP cable has to
be inserted into the transceiver board with reference to the side (A or B) of the transceiver
on which the particular receiver is installed.
Figure 22 shows receiver RX1 installed on the backside (side B) of transceiver TRX1.
The FTP cable for RX1 then needs to be plugged into the BUS B connector of TRX1.
RX2 is installed in front (side A) of TRX1 and the FTP cable for RX2 thus needs to be
plugged into the BUS A connector of TRX1.
Power supply connections are not shown in the image but are described in chapter 6.5.
