Wiring
Wire the DGP terminals as shown in Figure 4 . Earth wires from all pieces of equipment must be grounded at
one system earth. For more information on grounding details, refer to the Alliance control panel’s installation
instructions.
Figure 4. Wiring diagram
Table 1 shows the DGP wiring terminal details.
DGP to Alliance control panel wiring restrictions
You can locate the DGP up to 5,000 feet (1.5 km) from the Alliance control panel. The DGP must be connected
via a 2-pair twisted, shielded data cable from the system bus connection. We recommend you use Belden
8723.
Where the DGP power supply source is at a distance greater than 328 feet (100 m), you must use an external
supply. We recommend a supply output of 13.8 VDC 1 A fused.
