2 LBB 1990/00 Plena Voice Alarm Controller

Each message can have any length within the total available capacity. Messages and configurations are uploaded from a PC via USB 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 17 minutes of recording time with CD-quality signal-to- noise ratio.

The unit has 12 contact trigger inputs for business and emergency (EMG) calls. Each can be configured for a message consisting of a sequence of up to 8 wave files. In this way some wave files may be used in different combinations with other messages, optimizing flexibility and used storage space. Multiple messages can be merged to form one integrated message. Together with this sequence, for each trigger input, a zone selection can be configured.
