Our Mission

SED Inc. is committed to design, develop, and manufacture innovative solutions that are intuitive, reliable & rugged for use in highly demanding applications.

Our Story

In 1971, SED began with manufacturing specialized Throat Microphones and customized Headsets for the Canadian nuclear industry. 

In 1980, SED developed a Combined Air/Communication™ Hose for the nuclear industry, which reduced the hassle of running a separate wire for communication and hose for air supply to the plastic suits.  Over time, we have developed several “Air Distribution & Communication” accessories to accompany the Combined Air/Communication™ and Air Only Hoses.

In 1991, SED created a unique Intrinsically Safe system called the “Rescom® Classic™” which later became the “Rescom® Modular™” in 1998. This communication system is an intrinsically safe, full-duplex, hardline communication system, designed for use in confined space entry & high-angle rescue scenarios.  To this day, this system continues to be the industry standard and meets all intrinsic safety requirements of MSHA, CSA and UL and other standards of NFPA and OSHA.  We are the only manufacturer of a Combined Safety/Communication™ Rope which has integrated communications wiring in a safety lifeline to simplify line management while providing clear, continuous and effective communications in underground & communication-dead areas.  With NFPA certification, this 10,000 lb. tensile strength rope can be used as a primary or secondary lifeline.

By 1993, SED had grown to design and manufacture small-scale communication hubs (Vcom™) for Coast Guards and by 1995, large-scale industrial intercom systems (ProCommander™ III and ProCommander™ IV) for the nuclear industry by 1995.  These products continue to be trusted worldwide by leading nuclear organizations and are known for their robust design & exceptional build quality.

In 2002, SED expanded its intrinsically safe product portfolio by introducing the HALO® series of intrinsically safe headsets and radio accessories.  The VOX/PTT interfaces and a wide range of accompanying headsets, make it possible to expand the versatility of your radio, without compromising intrinsic safety. These products are ideal for incendive & explosion-prone areas and are approved by CSA & UL.

After a long & successful relationship with the nuclear industry, SED recently developed Human Performance Trainers (HuPerT™).  These training devices and programs are designed to help prevent, anticipate and minimize human performance errors in any process control environment where safety and cost-effectiveness are of key importance.  These Human Performance Trainers can augment existing training programs or we can offer full training courses through our sister company ROPA Technologies Inc.

In 2022, our legendary rescue communication system, Rescom® Modular™, was advanced to the Rescom Elite® to meet ATEX, IECEX, CSA, UL and CE requirements.
