Intercom and public address system for industrial environments with potential explosion hazards (ATEX classified zones) or harsh marine environments, allowing two-way spoken communication between each intercom and the ID-500 control station. The INTERCOM-500 system supports up to 40 intercom points in a radial configuration. It allows the installation of one or more ID-500 control stations and call forwarding to be answered by a telephone exchange or simply by a DECT cordless phone, using a telephone card expansion (IW-18).
