Getting started

The BlackBerry® AtHoc® management system uses the IIM add-on module interface with Giant Voice (GV) outdoor warning devices to enable wide-area Mass Notification System (MNS) broadcasts. Giant Voice features can broadcast critical information using voice messages, wave files, musical tones, or text-to-speech (TTS) conversion. Whelen GV supports outdoor Public Address (PA) systems that have large amplified speakers. Typically, speakers are set on poles in an array that covers a specified area with enough acoustic sound to override the ambient noise with emergency notification.
After the
BlackBerry AtHoc
management system is integrated with a Whelen Giant Voice System, operators can disseminate emergency alerts to the siren system from the
BlackBerry AtHoc
management system. Alert messages can be delivered using text-to-speech or pre-recorded audio files to up to three pre-defined target zones by using the external call key inputs. A fourth external call key input is reserved for sending a "Cancel" command to all poles.
