SEL ALERT digital multi-channel voice notification system


The SEL ALERT module is designed to provide automatic emergency voice notification of subscribers, assigned by database (list of employees who are to be informed) by telephone lines, loudspeakers (relaying system), radio communication (when radio stations are activated), computer and paging networks, and transfer of information of emergency situations, as well as in case of declaration of total mobilization or state of emergency.

After forming of distribution list and recording of voice messages the calling process is initiated by operator from PC or automatically. The system performs calls to specified number (several numbers) from the list and analyzes signals of telephone line. If recipient picks up the handset, message transmission begins. The feature of recording of recipient’s response is provided. The recording results are saved in PC with indication of date, time, duration of call and result of notification.
