6.10 Connecting the VESDAnet wires to the Termination Card (VN
model only)
a. Refer to Figure 6-6 for the network terminals location on the termination card.
b. Connect the VESDAnet wires as shown in Figure 6-9. This diagram is only an example for five detectors.
This wiring method is similar for two or more detectors.
c. Maintain the wiring polarity throughout the network and do not leave any VESDAnet terminals
unconnected.
Notes:
l While an Open Loop configuration is possible (refer to System Design Manual), it is strongly
recommended that the Closed Loop configuration be installed to achieve a fault tolerant loop
l When a VN model detector is not used in a VESDAnet loop and is to be used as a stand-alone detector
the VESDAnet terminals must be wired as per Figure 6-10.
