Description:
The LBB 1965/00 Plena Message Manager is a high-performance, standalone digital message player designed for diverse applications, including public announcements, emergency evacuations, and background messaging. It supports up to 500 seconds of recording time in uncompressed WAV format, ensuring superior audio quality.

Applications:
Ideal for use in public facilities such as shopping malls, theme parks, schools, office buildings, and any environment requiring automated, high-priority messaging.

Advanced Functions:

• Message Storage and Playback:

  • Stores up to 12 WAV files in its internal 64 Mbit EEPROM with over 10 years of data retention.
  • Messages are uploaded from a PC via RS-232 and do not require battery backup.
  • Playback is triggered by contact closures, with priority-based sequencing and zone configuration.

• Trigger Inputs:

  • 12 trigger inputs, with the top 6 reserved for high-priority messages.
  • Configurable for sequential playback of up to four messages per trigger.
  • Front-panel switches allow configuration of lower-priority inputs without a PC.

• Supervision and Fault Detection:

  • Continuous system checks for data integrity and hardware reliability.
  • Cable supervision for the six high-priority triggers prevents operational failures.
  • Fault conditions activate a fault output relay and illuminate a red LED.

• Emergency and Evacuation Compliance:

  • Meets IEC 60849 standards for emergency sound systems.
  • Integrated pilot tone supervision ensures output integrity for amplifiers and speakers.

• Seamless Integration:

  • Loop-through capability with balanced XLR and unbalanced cinch inputs/outputs.
  • RS-232 interface for communication with the LBB 1925/10 Plena System Pre-Amplifier, enabling zone-based playback.

• User-Friendly Monitoring:

  • Headphone jack for message content monitoring.
  • Front panel controls for simplified configuration of triggers.
