Intrinsically Safe (IS) wireless products are designed specifically for use in hazardous environments, such as oil refineries, chemical plants, flour mills etc where inflammable gases or explosive dust may be present. IS products require designs that preclude the possibility of sparks being generated by high electric fields, intermittent electrical connections (eg when changing a battery or when dropped) etc. Traditionally, only PMR or pager products have generally been designed to IS standards and thus have had something of a monopoly for on-site wireless communications in such environments. The advent of IS DECT products means that staff in such environments can now enjoy cordless communication via the normal site telephone system to external contacts as well as on-site employees.
Alcatel 200 Ex Reflexes is a specially conceived Ex-approved DECT handset for safe operation in hazardous environments.
