The Spectra^® Sound Masking System must provide the following:

• All masking/paging units must be UL Listed for air handling space.
• Each self-contained masking (sound generating unit) must have individual volume and spectrum shaping controls and a paging/music volume control which are active and readily accessible for user adjustment to suit zones of 225 square feet or more.
• Each sound generating unit contains an independent sound generator to eliminate phasing effects.
• In open areas and larger enclosed spaces, the overall sound level produced should have spatial uniformity of no more than +/ - ½ dBA between any two sound generating units.
• The sound generating units must have a step attenuator, a rotating volume control for precise sound level adjustment, a rotating spectrum shaping control, and a rotating volume control for paging/music.
• The units shall be able to produce up to 86 dBA to meet the requirements for all ceiling treatments.
• The sound generating units must have adjustable sound spectrum shaping controls in order to meet the varying spectral requirements of drywall ceilings, various types of ceiling tile, air return grills and openings around lighting fixtures, etc.
• The sound generating units must be random sequence sound generators and not produce a noticeable repetitive pattern or sequence.
• Sound masking must have E-sound® technology.
• The spectrum shaping ability shall be variable within the accepted background sound masking range.
• Units installed over drywall ceilings should be wired for spectrum control adjustment and remote sound level.
• Speaker housings/ enclosures must be damped to avoid undesirable resonance, etc.
• The system must have the capability to provide paging simultaneously, on an all-call or individually zoned basis.
• The paging volume control must be totally independent of the masking volume and smoothly override the masking. Paging power usage should be .0125 watts per 450 square feet.
• Paging system must have IndePage™ technology.
• All components and assemblies are to be production models of proven performance with continuity of the manufacturer throughout the system for individual component items.
• System shall be designed so that individual speaker or component failure will have no impact on the balance of the system.
• Design of system must be powered by low voltage of 16/18 volts. Power usage should not exceed 100 watts per 18,000 square feet for masking and 200 watts for masking and paging.
• System shall be warranted to be free from defects in materials, workmanship, and performance for a minimum of 10 years from date of installation.
• System must have a Privacy Reporting Feature and use SPEC™ software.
• System must confirm following ANSI standards: ANSI S1.4, ANSI S1.6, and ANSI S1.11.
• Sound masking system must meet ASTM E-1130 standards for speech privacy and sound uniformity.
• System must use at least 50% recycled content.
• System must be manufactured in the USA.
