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.

The Halo® SRI Interface is an in-line interface for use between a hand-held portable Radio and a Headset.  The Halo® SRI unit requires no power and provides the User with a remote PTT button near his/her chest, allowing the User to operate a portable Radio in difficult-to-reach conditions.  A large 4cm (1.5”), easy-to-locate, jam-proof PTT button makes HALO® SRI a perfect choice for use with bulky gloves and in tight spaces.  

What is Intrinsically Safe?

Intrinsically Safe means that the system is incapable of causing an explosion or being 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.
