Bosch - Plena message manager
2006
 

The Plena Digital Message Manager stores up to 12 separate messages recorded using the standard Windows® WAV file format.

Via any of its 12 trigger inputs, it can replay announcements of up to 4 messages routed to user-determined zones (in combination with the Plena System Pre-Amplifier). Trigger inputs have sequential priority, and are remotely activated, although inputs 7 to 12 also feature front panel activation. Messages are downloaded from a PC into the unit's built-in flash memory via RS232.

Audio quality is set by adjusting the sampling rate from 24 kHz (near-CD quality) to 8 kHz (maximum message time of 500 seconds).

The message manager functions as a stand-alone unit as the PC is disconnected once messages have been downloaded. The Windows® software (supplied) takes care of downloading messages and configuring and routing of announcements. The unit features built-in system checks and other safety features for providing emergency and evacuation messages in IEC60849-compliant systems.

  • Up to 12 messages totaling up to 500 seconds
  • 12 trigger inputs with front-panel and remote control
  • Plays an announcement of up to 4 messages in sequence per trigger
  • Zone control for the Plena System Pre-Amplifier
  • Complies with IEC60849 for emergency sound systems
