Abstract: A mass occupant notification (MON) system includes an alert source, a first communication network, a MON supervisory system, a second communication network, a satellite radio broadcast network (SRBN) system and a plurality of MON communication units. The alert source, such as a telephone, personal computer or emergency sensor system, generates an alert signal containing information regarding an emergency situation. The first communication network communicates the alert signal from the alert source to the MON supervisory system. The MON supervisory system receives the alert signal and generates an alert message which includes audio message data and destination data. The destination data indicates a destination of the audio message data. The audio message data may contain a voice announcement providing information or instructions regarding the emergency situation. The second communication network communicates the alert message from the MON supervisory system to the SRBN system.

Abstract: An emergency event reporting apparatus operates in conjunction with a satellite-based data relay system. The emergency event reporting apparatus includes an emergency alert transmission system and an emergency alert management system. The emergency alert transmission system transmits emergency alert messages upon detection of an emergency event. The emergency alert transmission system includes one or more emergency alert sensors, an alarm control panel and an alarm beacon unit. The emergency alert sensors detect characteristics associated with the emergency event and generate sensor signals based thereon. The alarm control panel receives the sensor signals and generates alarm signals based thereon. The alarm beacon unit receives the alarm signals and transmits an alert message based on the alarm signals. The alert message includes identification information and alert message information regarding the alarm signals.
