System Expansion
The D5RH is capable of supporting up to four sources to up to four zones. The system may be
expanded in two ways:
• Local Sources
• Adding Zones
Local Sources
Each zone of a D5RH-based system can have its own “Local” source connected directly to the zone’s
D5KP Amplified Keypad using a D5IP Source Input Wall Plate. A source connected to a D5KP is
accessible from the zone in which it is connected. It is NOT AVAILABLE to the other zones of the
system. Both audio and IR control capabilities are available to Local Sources through the D5KP. A
zone may have a maximum of one Local Source.
