8. Quantity of fixtures for the controlled lighting zone. This is useful, along
with item #6, in calculating the total power rating (watts) for that particular
controlled circuit (item #9).
9. Total Wattage, or Power Rating, of the controlled lighting zone. This is
required in order to determine the total number of Crestron Lighting
Module channels required for that particular zone, especially if the load of
the total number of fixtures exceeds the rating of a single module channel.
NOTE: National and local electrical codes and the functionality of each user-
interface must be taken into consideration. Always install electrical devices
according to the national Electrical Code (NEC), local codes, and with safety in
mind.
Equipment List Specification
The equipment list is based on the requirements collected for the lighting system in
the load schedule. This is a sequential step-by-step process. The information
gathered in previous steps is required to complete following steps. Once all the steps
are completed, a complete bill-of-material for the system is created. The seven steps
are as follows:
•
Module selection – based on the number and type of loads
•
Enclosure selection – based on the number of modules and
locations
•
User interface selection – based on the user control requirements
•
Wiring plan – based on the previous steps and the layout of the
environment
•
Control processor – based on the size of the system (large systems
should have a dedicated processor)
•
Network block selection – based on the layout and distribution of
the loads
•
Accessories selection – based on the required accessories (third
party telephone and alarm systems, etc.)
NOTE: Crestron D3 Pro software is the ideal tool for specifying an equipment list.
A fully documented help file supports the easy-to-use screens and views. It offers the
designer a starting place for determining modules and enclosures. The Crestron D3
Pro software can also generate a load schedule report. Refer to the latest version of
the Crestron D3 Pro Reference Guide (Doc. 5998) available from the Crestron web
site (www.crestron.com) for detailed information about D3 Pro.
