Plena Voice Alarm System | Installation and User Instructions | Glossary
Reset
Faults and EMG triggers should first be manually
acknowledged before they can be reset. The Fault/
EMG Reset button is located on the frontside of the
controller.
Router
A router (LBB1992/00) can be used to extend the
total number of zones. In total 6 routers can be
connected. Each router adds 6 extra speaker zones,
thus a Plena Voice Alarm System can manage 60
zones in total.
RS-232
Asynchronous interface protocol for point-to-point
communications, between the controller and an event
logger. Each cable end is provided with a 9-pin D sub
connector.
RS-485
Serial interface protocol over twisted pair cables for
multipoint master/slave communications within the
Plena Voice Alarm System. Each cable end is
provided with an RJ45 connector.
S
Supervision
In compliance with the international standard
IEC60849, various functions in the Plena Voice Alarm
System are supervised. Any failing function will
illuminate the corresponding LED on the frontside of
the controller/router. Supervision can be switched
OFF by setting the Supervision DIP switch on the
rearside of the controller to OFF.
System fault
A system fault is the Plena Voice Alarm System is
indicated by the corresponding LED on the frontside
of the controller/Router. All relevant system functions
are supervised.

T
Trigger input
The rearside of the controller provides 6 EMG and 6
business trigger inputs. All inputs can be used to
signal events to the controller. However, the EMG
inputs have a higher priority range than the business
inputs.
U
USB
Universal Serial Bus, used for communications
between the controller and a PC.
V
Controller
The voice alarm controller is the heart of a Plena Voice
Alarm System. The controller, a digital network
controller, manages all incoming spoken messages
from the call stations, all EMG messages, whether live
spoken or prerecorded, and directs them to the
correct speaker zones.
VOX
The controller has one mic/line input with VOX (voice-
activated) functionality. The input can be used to
connect an additional emergency microphone or to
interface with another emergency sound system (e.g.
a Praesideo system). A VOX microphone is always
ready-to-transmit enabling handsfree applications.
VU
A VU meter, or Volume Unit meter. The 4-LED colored
bar in the upper left corner on the front of the
controller indicates the sound level (in dB) of calls and
BGM.
W
WAV
Sound file format used to store prerecorded (alarm
and alert) messages in the controller. The properties
of used .wav-files should adhere to:
8 KHz < sampling frequency < 24 KHz; 16-bit; mono.
