Details
The Plena message manager is a high performance, highly versatile stand-alone digital message player. Applications range from spot announcements in supermarkets and theme parks to warning and evacuation messages in emergency situations.
With the LBB1965/00 up to 12 messages can be stored in the internal 64Mbit EEPROM, without the need for data retention battery backup. Each message can have any length within the total available capacity. Messages and configurations are uploaded from a PC via RS-232 into the memory, after which the unit operates without PC connection. The standard WAV-format is used for the messages, and sample rates of 8 kHz up to 24 kHz with 16-bit word length (linear PCM) are supported. This gives up to 500 s of recording time with CD-quality signal-to-noise ratio. The use of linear PCM instead of some sort of compressed audio format (like MP3, ADPCM and u-law/Alaw) ensures high-quality playback of all types of audio signals, including sound effects and special tones, such as attention chimes.
The unit has 12 contact closure trigger inputs for announcements. Each can be configured for a sequence of up to 4 messages out of the available ones. In this way some messages may be used in different combinations with other messages, optimizing flexibility and used storage space. The LBB 1965/00 can also play emergency/evacuation messages, as it fulfills the IEC 60849 standard.- Features
