Halo® Series offers more Intrinsically Safe Radio accessories than any other Radio Communication System in the market.  It allows Users to connect Headsets and Radios using a UM (VOX/PTT) or SRI (PTT only) interface or just connect the headsets with a host radio.  Hazmat, high noise, wet and dirty environments, can finally be handled with confidence using the HALO® Intrinsically Safe series.  The belt or carabiner mount Interfaces are energy efficient and can last several days without recharging.  With a choice of application-specific Headsets and the clearest audio in the business, HALO® Series makes it easy to add versatility to your existing Radio Communication System without compromising intrinsic safety.

HALO® UM Interface can be fitted to most popular brands of hand-held Radios, via an adapter cable.  It is available in two variants i.e., with a recessed (UM7) or raised (UM8) PTT button, providing Users more flexibility to use it in various environments.  Using the Halo® UM 7/8 Interface, the User can communicate either by PTT mode or VOX mode.  The jam-proof PTT button makes HALO® UM a perfect choice for use with bulky gloves and tight spaces.  For PTT mode, one can press the large easy to find 1.5” (4cm) button.  For VOX mode, switch the unit to the “ON” position and then one can communicate hands-free.  A switch guard prevents accidental VOX shut-off during operation and the VOX mode LED indicator provides low battery indication.  Radio traffic is monitored at all times, regardless of the mode, so you never miss an emergency announcement.

What is Intrinsically Safe?

Intrinsically Safe means that the system is incapable of causing an explosion or be a source of ignition in the presence of potentially explosive or combustible materials and gases.  In other words, the equipment and wiring are incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most easily ignited concentration.  OSHA and MSHA have many reports of fires caused by non-intrinsically safe systems.  Preventing fire and explosions is a top priority for all industries around the world.
