6.1.1

VESDAnet Terminals (VN Model only)

The VESDA VLC-EX detector can be connected to VESDAnet through the VESDAnet terminals on the
Termination Card. The terminals enable VESDAnet communication cables to be brought into the detector and
then looped out to another device. Data communication between the detector and other devices on
VESDAnet are bidirectional. The polarity of the data wires must be maintained throughout the network. It is
recommended that RS-485 (BELDEN 9841 - 120 Ohm) twisted pair cables (or similar) be used.

Note:

The VESDA VLC-EX is shipped without the VESDAnet A and B channels looped. If the detector is
not to be networked with other devices, then loop the A and B channels, as shown in Figure 6-3.
