Public address and general alarm system ( PA/GA )

NOVA
PA/GA Equipment For Hazardous and Non-Hazardous Environments

The NOVA Public Address and General Alarm (PA/GA) system utilises microprocessor technology to provide superior performance and reliability for all types of facilities. The PA/GA system can be divided into one or more zones which can be accessed independently for announcement or alarm broadcasts.

Loudspeakers and/or beacon circuits support paging zones where one or more loudspeaker circuits can be grouped into a zone. Each loudspeaker or beacon circuit is connected to the central equipment for amplification and control / monitor functions. The system can interface to other systems such as telephone, radio, or other paging/intercom systems. Up to 64 individually prioritized audio interfaces are supported. Additional interfaces support external alarm/monitor systems; NOVA can activate external system alarms and, accept external system alarm/audio inputs initiating both alarms and beacon/strobes.

Touch screen desktop or rack access panels allow
voice announcements and alarm control operations. Announcements can be configured to broadcast in designated zones, or a zone selection feature enables users to direct announcements to selected zones. Access panels are connected to the central equipment and assigned an access priority for announcements, thereby ensuring that the panel with the highest authority level takes precedence over lower level panels. Alarms are likewise given a broadcast priority that gives the most critical alarm precedence.
