The Plena call station is a stylish, high-quality call
station with a stable metal base design, a flexible
microphone stem and a unidirectional condenser
microphone. It can make calls to selected zones (one
to six and all-call) in a public address system built with
the Plena Voice Alarm System. In addition to tabletop
use, the special design allows it to be neatly flushmounted in desktops. The Plena Voice Alarm Keypad
(LBB 1957/00) is an extension adding seven additional
keys.
Functions
Each call station supports six zone selections. The
number of selectable zones or zone groups can be
increased by connecting call station keypads
(LBB 1957/00). Up to eight keypads can be added
with each keypad adding seven zone or zone-group
keys.
This call station features selectable gain, a selectable
speech filter, and a limiter for improved intelligibility.
The call station has a balanced line level output,
making it possible to position it up to 1000 meters
from the controller, using CAT-5 extension cables.
With shielded cable, the call station can also be used
in an EMC level 5 (heavy industry) environment.
DIP switches at the base of the call station select
different microphone gain levels, the call station ID,
and the speech filter. A service accessible rotary
control provides microphone level attenuation. LEDs
on the call station show which zones have been
selected. Three additional LEDs give visible feedback
on the active state of the microphone and the system.
Green flashing means standby (chime is sounding).
Green indicates microphone active. Amber indicates
that the system has detected a fault, and red indicates
that the system is in the emergency state.
