(c) On the termination card, remove the plugs from its terminal sockets.
(d) Insert the correct wires into the terminal plugs.
(e) Tighten terminal plug screw.
(f) Repeat steps (c) to (e) as required.
(g) Insert plugs into the correct sockets on the termination card.
(h) Check the wires are attached to its terminals.
(i) Ensure no bare wires are exposed at the terminals. The wire insulation must touch the
terminal plugs at the pin connection opening.
(j) Check the terminations are correct by referring to the appropriate circuit diagrams in
Sections 6.13, 6.14 and 6.15.
6.13 Terminating the Power Wires to the Termination Card
a) Refer to Figure 9 or 10 for the location of the power terminals on the termination card.
b) Connect the power wires to the Power terminals as shown in Figure 11.
Figure 11 Wire Connection Details for Power
6.14 Connecting the VESDAnet Wires to the Termination Card (If required)
a) Refer to Figure 9 or 10 for the VESDAnet terminal location on the termination card.
b) Connect the VESDAnet wires as shown in Figure 12. 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.
Do not leave any VESDAnet
terminals unconnected.
NOTE:
The detector is shipped from the factory with the VESDAnet terminals linked as shown
in Figure 13. If the detector is not to be used in a VESDAnet loop and is to be used as a
stand-alone detector the VESDAnet
terminals must be wired as per Figure 13.
NOTE:
It is strongly recommended that the Closed Loop configuration shown in Figure 12 is
installed, to achieve a redundant fault tolerant loop. An Open Loop configuration is
possible by not linking the VESDAnet wires between detector 1 and detector 5. Detector
1 and detector 5 must be programmed to the Opened Loop Configuration.
