  1. Domain A – Provide AV Solutions Domain B – Operate AV Solutions Domain D – Troubleshoot AV Solutions CTS Prep Part Two

  2. Part Two • Domain A – • Sell AV Solutions • Conduct Vendor Selection Process • Provide AV Solutions • Domain B – Operate AV Solutions • Domain D – Troubleshoot AV Solutions

  3. Sell AV Solutions • Best Practice • Show courtesy to the client, other trades, and coworkers. Defer jobsite questions to the project manager. • Everyone who comes into contact with clients and other trades in the course of their work must consider themselves a salesperson for their company. • Simple courtesy can pay off in cooperation between trades, and certainly can make a difference in the attitude of the client towards the workmanship and quality of service for which they are paying. This can mean referrals and repeat business. Ch 25

  4. Sell AV Solutions • Effective Listening • The Decision Maker • Customer Service • A customer’s satisfaction means continued business and possible referrals. Listening to the clients' needs, working with the clients to satisfy those needs, and updating the clients on the status of their solution require highly developed customer service skills. Ch 25

  5. Sell AV Solutions Exercise Everyone in an organization who comes in contact with clients and other trades in the course of their work must consider themselves as a _____. • salesperson • installer • designer • accountant

  6. Part Two • Domain A – • Sell AV Solutions • Conduct Vendor Selection Process • Provide AV Solutions • Domain B – Operate AV Solutions • Domain D – Troubleshoot AV Solutions

  7. Courtesy of Crimson Tech    Conduct Vendor Selection Process • Best Practices • When the equipment is delivered, make sure the equipment is properly received and unpacked. • Confirm that it meets project specifications. • Test the equipment before it is delivered to the project site. • Collect all the accompanying documentation – warranties, instruction and owners manuals, etc. Ch 24

  8. Part Two • Domain A – • Sell AV Solutions • Conduct Vendor Selection Process • Provide AV Solutions • Domain B – Operate AV Solutions • Domain D – Troubleshoot AV Solutions

  9. Control Systems Controlled Functions User Interface Dashboard for Controls Commission system Punch-list Demonstrate and Test Equipment Create Documentation Training Domain A - Provide AV Solution • Install elements • Tools • Projector Orientation • Loudspeaker Systems • Cable Considerations • Mounting • Power Ch 19

  10. Install Elements • Create a tools checklist • Best Practice • Each setup will require different equipment. Note the equipment needed for each job, and keep it in the job file. When you are picking up the equipment and assembling it for installation, a quick glance at the checklist will let you know everything is ready to go. If the installation is temporary, use the checklist during the strike to account for all the equipment. Ch 19 – Pg 375

  11. Install Elements • Projector Orientation • Front-table • Front-ceiling • Rear-table • Rear-ceiling • Best Practice • Check the structure for vibrations by resting your hand on the beam or bar-joists. Sometimes the HVAC unit is mounted on the roof above, creating vibrations which will cause the image to appear unfocused. Ch 19 – Pg 399

  12. Install Elements • Loudspeakers • Point-Source and Distributed Systems • Point Source- deliver very loud sound coming from one location • Distributed Systems- loudspeakers strategically suspended overhead or installed into the ceiling

  13. Install Elements • Conduit – tubular, solid and circular  • PVC (plastic) Conduit • Electrical Nonmetallic Tubing (ENT) • Inner Duct • Rigid Nonmetallic Tubing  • Metal Conduit • Electrical Metallic Tubing (EMT or thin wall) • Flexible Metal Conduit (Flex) • Intermediate Metal Conduit (IMC) • Rigid Metal Conduit (Rigid) • Cable Installation • Raceways • Ducts – typically rectangular  • Cable tray • Trough – aka wireway Ch 19 – Pg 389

  14. Install Elements • Cable Installation • Permissible Areas • The certain maximum amount of space that cables should occupy inside the conduit. • 1 Cable = 53% of conduit area • If you are running only one cable in a conduit, that cable may occupy up to 53% of the conduit's inside area. • 2 Cables = 31% of conduit area • If you are going to run 2 cables inside a conduit, these 2 cables may occupy up to 31% of the conduit's inside area.  • 3+ Cables = 40% of conduit area • If you are going to run three or more cables inside a conduit, the cables may occupy up to 40% of the conduit's inside area.

  15. Install Elements • Cable Installation • Signal Separation • Refers to providing physical distance among cables carrying various signal levels • When grouping cables together in a bundle, all cables should be intended for only one signal type. Generally, group cables according to these guidelines: • Microphone • Line and communication • Control and data • Loudspeaker • AC technical power • Video • RF Best Practice Consider color coding cable to help maintain separation when you are bundling cables. Color-coding requires stocking more cable, but it can speed things up with a big bundle. You should always label cables as well. Ch 19 – Pg 386

  16. Install Elements • Mounting Safety Tips • Safety first! • It is important to define the specific parts that you will be using and to use the parts that are defined. Include the following information: • Review the size and weight of what you will be mounting, along with all the parts and their weights. • Verify the location of the mounting. • Look at the structure to which you will be mounting, and assess any potential problems. • Look at the structural designs of the room or building to ensure safety. • Review all manufacturer guidelines and drawings. • A structural engineer should review all mounting plans and advise on any difficult situations that you may encounter. When in doubt, always ask for help. If you modify another contractor’s work, you become responsible.

  17. Install Elements • Mounting Safety Tips • Load Weight! • Best Practice to multiply the published design weight by five. If a loudspeaker with mounting hardware weighs 100 lb (45kg), you should use mounting criteria that will handle 500 lb (225kg). Five is the safety factor. The term safety factor is sometimes referred to as design factor, load factor, or safety ratio. • Remember, the weakest point in the assembly is as strong as the entire assembly can be. • Mounting Malfunction – Shear – Tensile – Pull-out Ch 19 – Pg 395

  18. Install Elements • Mounting • Mounting is the practice of suspending or attaching components to the structure of a building. • Fasteners • Best Practice • It is best to get your fasteners from a reputable organization. • A local hardware store may not have grade 5 or 8 hardware in stock • Floor Mounting • Overhead Mounting • Wall Mounting Ch 19 – Pg 395

  19. Install Elements • Where does Power Come From? • Power generation station • High voltage transmission lines • Electric substations • Local transformer

  20. Install Elements • Power on site • Service Drop • Service entrance • Electrical Service-Equipment Entrance Panel • Main Distribution Panel • Feeders • Subpanels • Individual branch circuits • Wall outlets • Directly wired equipment Ch 9 – Pg 166

Ch 21 – Pg 443 - 446

  30.
