Distributed Architecture
Product Families: Room Solutions
• Wired in traditional configuration
• Each load is controlled by a local Crestron device. In some cases, the local device has integrated
on-board keypad
• Keypad and touch screen control are optional, allowing that load to be controlled from any location
In a distributed system the high-voltage lighting, motor, fan, and switch circuits are wired in the traditional
configuration with local control. Controllable in-wall dimmers or switches replace the standard dimmers or
switches and can be retrofitted into a project after customary high-voltage wiring is completed. Crestron in-wall
dimmers communicate with a control processor through either a Cresnet (low-voltage control wire) or infiNET EX
®
(mesh RF) wireless connection. This design combines the familiarity of local control with the power and flexibility
of automation. In the event of a control system interruption, the user can still operate the lighting locally.
In the commercial space, in-wall solutions are appropriate for offices, small boardrooms, and hospitality. Typically
in-wall dimmers or switches support standard voltages (120/230 Vac) and load types (incandescent, magnetic
low-voltage). In the case where higher voltages and loads are required, an expansion module can be added.
Hybrid Architecture
Product Families: Mix centralized and distributed products.
• Combines both centralized and distributed architectures
• Offers complete building/enterprise control through flexible combinations of products
A hybrid system is a mix of both the centralized and distributed design. This allows local control where needed
alongside sophisticated central control for larger spaces. For example, a boardroom could have distributed local
control while the lobby is on centralized control. Hybrid designs typically achieve a good balance, delivering the
control necessary at a reasonable budget. In many commercial spaces, mechanical/electrical room space is
limited (this is where the Green Light enclosures must be installed). By using a reasonable mix of centralized and
distributed control, entire buildings can be connected to a control network which offers total control, monitoring
and management.
