As your interlocks are installed, keep track of which ones are wired
Normally Open and which are Normally Closed .
This information will be required for completion of the system configuration procedures described in Chapter 3.
Wire Network Connections
To wire two or more ORS SITEPRO™ panels together into a network, use a high quality shielded twisted pair cable and
wire as shown in figure 12 (below). Wire the conductors from terminals 10 & 11 of TB4 on one panel to the same
terminals on the next. On all but the last panel in the network, connect the shield to the terminal 12 on TB4. Do not splice
shield segments together.
Figure 12
Wire each interlock device to the ORS SITEPRO™ panel as follows:
1. Run the intrinsically safe interlock wires through the access port on the side of the
ORS SITEPRO™ enclosure. Run non-intrinsically safe interlock wires through the
port at the bottom of the enclosure. Use 20-25 AWG wire in all cases.
2. For intrinsically safe interlocks , attach one wire to terminal 1, 2, 3 or 4 of TB2 and
the other to one of the +5VDC intrinsically safe terminals on TB1. For non-intrinsically
safe
interlocks , attach one wire to terminal 1, 2, 3 or 4 of TB3 and the other to one of
the COMMON terminals on TB3.
Refer to figure 11 (below) for an example of interlock wiring.
In this example, Normally Closed pressure switch is wired to intrinsically safe terminal
strips TB1 and TB2. Because the switch is wired to terminal 4 on TB2, an alarm will be
generated on Channel 4 when the switch opens. The second wire from the switch could
be attached to any of the +5VDC
intrinsically safe terminals on TB1.
