1 PART 1- GENERAL

1.1 PROJECT SCOPE

A. This section covers the requirements for an Integrator to design, provide equipment for, and install instructional

classroom technology. This is intended to supply a complete instructional technology classroom that can be arranged

in multiple configurations. There will be a multimedia display as primary projection. Flexibility, integration of multiple

technologies and sources, and multiple user groupings are essential to this concept. As an example, all audio and

image sources should be capable of being shown on the screen and heard in the classroom. The work covered in this

document consists of furnishing all labor, material and services necessary to install a complete audiovisual system as

indicated on the project drawings and in these specifications.

B. Deliverables: Prior to ordering materials or commencing any construction activities, the Integrator shall provide the

Owner with a complete bill of materials, including all quantities of components, devices, equipment, and wiring

required to complete this work. Submit product data, including manufacturer’s data sheets for all proposed system

components. Submit three copies with all specific items that will be provided clearly indicated and any options

highlighted.

2 PART 2 - PRODUCTS

2.1 SYSTEMS DESCRIPTION

A. Provide a complete Audiovisual System for small to medium sized classrooms. The system switching and audio

amplification equipment shall be securely mounted and concealed in an enclosure above the ceiling mounted

projector. Audio and image source equipment can be connected to the system and displayed via four, active

(powered) interface panels located throughout the room. The audio and image signals from source devices shall be

transmitted from the active interface panels over standard UTP cabling architecture.

B. Classroom Definition: A classroom that has fixed instructional media video projection capabilities, Internet connectivity

at the operator's station, student networking (usually wireless), a document camera, VCR/DVD and/or other

multimedia input devices, standard laptop interface, multimedia control system that is connected to the network and

capabilities for additional add-on modular features.

Technology Enhanced Classrooms (TECs) use standardized control/interface systems and employ a standardized

operational protocol. The principles of this recommendation are to establish desirable goals with respect to classroom

design and installed technology. The TEC classroom standard includes control systems that have ADA, Section 508

compliant buttons that are discernible without activating the controls or buttons on the control panel, easily reached

control panel locations, closed captioning, hearing assistance capability, and user friendly operator protocols among

the features that are consistent with universal design principles.

All new construction general purpose classrooms will meet this minimum standard. The standard will be met in major

renovations wherever possible. The standard will be retrofitted in existing general purpose classrooms according to an

established upgrade plan.

2.2 GENERAL EQUIPMENT REQUIREMENTS

A. The room will be equipped with a standard easy to operate interface (a tactile button keypad layout). The audio

system may be monaural or stereo for program sound. The instructional media system will be controlled by a control

system with a control panel mounted near the operator's area. System parameters can be monitored, administered

and controlled over the data network. The instructional media equipment will be located within close proximity to the

operator's area or through a Graphical User Interface (GUI) on a computer to allow for ease of operation during

instruction.

Acceptable functionality requirements are listed below categorized by type of equipment. Quantities are listed for

movable, portable or loose equipment, and other selected entries. Where quantities are not listed, refer to the system

drawings.

B. The System components shall all be correctly listed and labeled by Underwriters Laboratories Incorporated (UL) for

their intended use.
