Pre-Wire Drawing Set

Definition: This is a drawing that shows where all wires (new or existing) are to be located in relation to the floor plan. Take the client's floor plan which is typically available in either PDF or DWG format and place icons along with the associated wire complement onto the plan. The following information should be conveyed: wire type, # of wires, origination point of wire and unique wire ID number. [Common Software: D-Tools, AutoCAD, Visio]

Why you should use it: The Prewire Plan serves as a road map for both the installation team as well as the client in case they need the project serviced in the future. The Plan should show all wire including wire that will be used immediately and wiring for future applications. If software such as D-Tools is utilized, you will also be able to pull reports which will aid communication such as: project management sign off sheets, installation reports, printable wire labels and unique wire ID's may be cross referenced to the project schematics. Specifying the correct wire ensures a smoother running installation.

Pre-Wire Drawing Set – Sub-System Only

Definition: This is a drawing that shows where all wires (new or existing) are to be located in relation to the floor plan.

Technical Power Plan

Definition: This is a project floor plan-based drawing showing line voltage requirements, power consumption data, and heat output data for a low voltage AV system. In addition the drawing should describe mounting height requirements for line voltage outlets that will be serving the low voltage system, such as TV locations. [Common software: D-ToolsAutoCAD, Visio, Excel]

Why you should use it: It is quite common that the AV system has changed the line voltage requirements for the structure. For example, TVs might require power outlets at floor, headend gear locations will require power, locations with sensitive electronics might have their power feed looped back to centralized surge and conditioning gear. This drawing will reduce confusion and increase communication between all trades resulting in a smoother running.

Lighting Load Identification Drawing(s) – Lighting Control System

Definition: A lighting control system drawing illustrates the load control method, load numbers and keypad locations. Every load in the project needs to be properly accounted for in terms of whether it is on the system or off the system. There are two primary control methods for controlling lights in a lighting control system: centralized or localized. Centralized loads have all of the wiring heading back to a dimming panel location and localized loads are controlled by replacing the "dumb" switch with a "smart" dimmer or switch. It is also important to illustrate which loads are not on the system so as to provide the client with a complete view of their system.

Why you should use it: This drawing makes it easy to convey to a client what you have designed for their project based on the design criteria provided during the discovery phase. Rather than sifting through a detailed proposal with part numbers that they may not understand, a client can easily understand the lighting control system by reviewing this drawing. The final version of this plan then gets handed to the project electrician along with additional system documentation so that he can perform his work with precision.

Rack Elevation – Full Color

Definition: Rack elevations show the location of equipment that is or will be located in a given rack. Racks are measured in rack units (RU) where one rack unit equals 1.75", usually starting at the bottom of the rack. If a piece of gear measures 2 Rack Units, it will measure 3.5 inches in height. [Common Software: D-Tools, AutoCAD, Visio, Net Zoom, Rack Tools]

Why you should use it: It is common to show both the front view and side view of the rack to ensure the selected gear will fit in terms of width and depth. Drawings should be labelled and dimensioned therefore providing an easy and effective road map for the technician who will be responsible for assembling the racks. Creating this drawing early eliminates many of the mistakes made during design and installation.

Schematics

Definition: Detailed input/output diagrams illustrating connections to be made between hardware. Drawings are commonly broken up by discipline such as Audio, Video, Control and Other. Another common method is to define Head-End interconnections on one page and then show multiple room connections on additional pages. [Common Software: D-Tools, AutoCAD, Visio]

Why you should use it? A Schematic is the most important piece of engineering documentation for any project. Whether you have a simple listening room or a large automation system, the schematic defines several very important system criteria: Resources: Every input and output for all hardware is shown Use: Gear is connected based upon intended use and scope requirements Wire Allocation: Every wire from the prewire plan is shown using the system schematics will drive your firm to a higher level of accuracy and efficiency. Sales – The salesperson sells an engineered proposal, not a parts list, Accounting – The correct gear is ordered the first time, Installation – The team follows the map as it is has been designed, Programming – Your programmer has their exact port assignments.

Installation Details

Definition: Accurate and dimensioned drawings created in Computer-Aided Design software. Typical applications include: User interface locations, TV bracket mounting requirements, motorized lift applications, projector/screen sightlines and speaker locations details. [Common Software: AutoCAD, AutoCAD LT, Visio]

Why you should use it? It is best to use these drawings when the details matter and getting it correct the first time is the only option. A project is accomplished in less time with greater accuracy when the details have been laid out in a drafting software package.
