GENERAL

This Performance Specification (PS) specifies the installation and quality of sound masking systems.

Note: A typical sound masking system consists of a network of speakers and amplifiers connected to a noise generator to raise the ambient noise level of a space to minimize audible distraction and provide privacy by masking intrusive speech. The noise generator typically provides pink noise, centered on the frequency of human speech, making indirect speech unintelligible. Real property, including raceway, cable tray, junction boxes, etc. are addressed in their respective UFGS sections and not included in this specification.

2.1 DESCRIPTION & MATERIALS

2.1.1 General

A. Materials used must be suitable for the environment in which they are installed and UL listed.

B. Sound masking system speakers and amplifiers must be non-proprietary.

C. [Utilize the most current approved version of Windows operating systems at the time of initial testing or as specifically approved for workstations and servers. Entire network must be supervised, monitored, patched, maintained, and life-cycled. Coordinate with Government to establish a plan of action for approval and dissemination of required Information Assurance Vulnerability Alert (IAVA) patches as well as software and security updates. Locate server in computer room (room code CMP01).] D. Disable any unused communications ports and protocols such that they can be reactivated by the government at a later date. Where Bluetooth functions are available, disable the Bluetooth functionality on delivery. The Bluetooth functionality must be able to be turned on after installation and review with the Cybersecurity Representative.

E. Directional Effect: People in covered spaces under calibration conditions cannot determine source of Masking sound.

F. Provide surge protection for sound masking system components. Integral surge protection devices listed in UL 1449.

G. Provide cabling and other appurtenances in accordance with the manufacturer’s recommendations.

H. Coordinate with Medical Treatment Facility (MTF) IT department for currently installed servers, switches, PCs and other similar hardware components. Where no manufacturer’s requirements conflict, provide hardware components to be fully compatible with those currently installed in the MTF.

I. System and other appurtenances must not have an anticipated end of system support in the next [18] [___] months. Systems being phased out are not acceptable.

J. [Integrate with paging system to provide sound masking and paging over the same speakers.] K. Sound masking system must mute during fire alarm and mass notification system signaling. [Provide UL 2572 listed system to interface with the fire alarm and mass notification systems.]

2.1.2 Noise Generator

A. Octave bands from 100Hz to 8000Hz.

B. Spectrum adjustments must meet acoustical preferred curve.

C. Filters for one-third Octave Bands: Adjustable from 10 dB of boost to 10 dB of cut at each center frequency.

D. Output octave bands must be from 30 to 4000 Hz.

E. Auxiliary Inputs: Able to accept two, high-level, auxiliary signals such as music and telephone paging as well as general paging.

F. Mounting: Mount with common rack with paging and music system headend equipment.

G. Central volume control and EQ control for zones and units for paging and audio.

2.1.3 Wire

A. UTP cable complying with manufacturer’s requirements; listed and labeled for environmental air plenums where cable is indicated in plenum spaces and is not indicated to be a in a raceway.

B. Minimum 18 gauge, stranded, non-shielded, and UL listed.

2.1.4 Masking Speaker Assemblies

A. Power Rating: [10] [___] Watts Root Mean Squared (RMS) B. Frequency Response: Within +/- [1] [2] [3] [___]dB from 50-15,000 Hz C. Pressure Sensitivity: SPL - at 1 Watt/m - 90 dB D. Assemblies installed in air-handling spaces must comply with NFPA 70 requirements for rate of heat-release and rate of smoke-release characteristics. Tests for these requirements must be according to UL 2043.

2.1.5 Component Mounting Racks

A. Configuration: Comply with CEA-310-E. Factory fabricated units designed for interchangeable mounting and enclosure of Standard 19-inch relay rack modules.
