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.
