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. Federal Signal 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.
BlackBerry AtHocmanagement system is integrated with a Federal Signal Giant Voice System, operators can disseminate emergency alerts to the siren system from the
BlackBerry AtHocmanagement console. Alert messages can be delivered using Key functions programmed in the Federal Signal hardware or software, text-to-speech or pre-recorded audio files to dynamically selected targets. Targeting choices are All Poles simultaneously, individual Zones of poles, and Poles.
