i.Net®  Networked Sound Masking

The i.Net Engineered System Solution uniquely addresses the proper requirements for sound masking, paging, and audio for today’s facilities. Each system successfully masks intrusive speech, creates privacy and delivers intelligible paging and audio solutions to ensure intended audiences are well informed and comfortable in their environments. 

i.Net now offers a UL 2572 listed solution to interface with the Fire Alarm Control Panel (FACP), in order to shutdown or mute the sound masking, in the event of a fire emergency. Moreover, i.Net is capable of reinforcing the fire alarm annunciation for a more intelligible message. Muting or shutting down the sound masking is a requirement of NFPA 72 (2010 code and beyond) and the ADA. Only a UL listed product is allowed to interface with a FACP.

The system offers virtually limitless zoning capabilities, plug and play speaker options as well as a revolutionary intuitive Graphic User Interface (GUI) for central system controls. The i.Net System is also capable of local, remote and Infrared (IR) controls. Floor-to-floor, building-to-building, across the campus or around the world, i.Net provides innovative and flexible solutions to enhance the workplace environment. Whether you are an established industry leader or an innovative organization poised for growth, we believe it is our responsibility to help you create a comfortable, productive and safe work environment.
