Section 2: Installation
Note: Any module can be connected anywhere along the Corbus. Separate wire runs for keypads, zone expanders etc. are
not necessary.
Note: No module can be more than 1,000'/305m (in wire length) from the panel. Do not use shielded wire for Corbus wiring.
Figure 2-3 Corbus Wiring
Module (A) is wired correctly as it is within 1,000'/305m of the panel, in wire distance. Module (B) is wired correctly as it is
within 1,000'/305m of the panel, in wire distance. Module (C) is NOT wired correctly as it is farther than 1,000'/305m from the
panel.
