The individual groups can be configured depending on project and customer-specific requirements.<\/p>\n<p>In complex industrial plants often many different group calls are defined which address individual areas or buildings (e.g. factory building, warehouse, etc.). For example, if faults occur in the course of a process, the employees in the corresponding areas can be informed by an announcement.<\/p>\n<h3><strong>Communication Procedure<\/strong><\/h3>\n<p>The operator at Station A presses the key configured with the desired group as target, keeps it pressed and speaks into the microphone (Push-to-Talk).

This means that an active group call overrides functions with a lower priority. A group call can only be interrupted by a voice connection or function with a higher priority.<\/p>\n<h3><strong>Pre-tones and Warning Beacons <\/strong><\/h3>\n<p>It is possible to play back a pre-announcement tone prior to a group call or the actual message. A positive effect is that listeners stop their conversations or noisy activities to focus on the announcement that follows.<\/p>\n<p>Furthermore, there is the option to activate flashing warning beacons which indicate the call visually.<\/p>\n<p>Download a more detailed version of this blog article as PDF <a href=\"https:\/\/www.industronic.com\/blog\/\/wp-content\/uploads\/2014\/10\/FDA-330-003-003_R01_EN_GroupCall_prel.indd_.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In my last two blog articles I described different ways of bidirectional communication.
