58 I ICT TODAY organize, label and thoroughly document the system during installation. Any existing equipment that will be integrated with the new system (e.g., amplifiers, phone system ports, computer networks, wiring, speakers, microphones) should be independently assessed and those assessment results should be documented before any new equipment is connected. If multiple technicians are involved in the installation, adhering to a common game plan will result in consistency of techniques and quality. Taking the right steps up front can be the differ- ence between a profitable and unprofitable job. It is much easier to troubleshoot a system when: • Those involved understand the intended operation of the system. • Up to date "As-Built" documentation is available. • All cables are labeled and neatly routed. • Unique cable colors and consistent wire pair color codes have been used. • All infrastructure terminations are labeled. • All equipment is visibly labeled with identifying information (e.g., areas served, MAC address, IP addresses). • New and existing subsystems have been inde- pendently assessed and the results have been documented. • Backups of any programming have been archived and cataloged. • A detailed summary of system operation is available. • A system of cross-connect blocks and patch cables is employed, allowing technicians to make and change direct connections easily between two different termination blocks (one for field wiring and one for equipment) within a termination closet. Perhaps, one of the most challenging decisions in a system design is speaker placement. Where should the speakers be placed to provide the best intelligibility? Design considerations include the following: • Type of ceiling (e.g., dropped ceiling, sheetrock, open) • Ceiling height • Room length • Room width • Height of speakers • Required dB level • Ambient noise levels • Environment (e.g., furniture, flooring, wall treatments) • Total square footage that needs to be covered LEARN ICT SKILLS AT YOUR OWN PACE Enjoy flexible, budget-friendly online learning solutions to optimize success with BICSI CONNECT.
