Call station
The Plena 6-zone 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 is intended for making
calls to selected zones (1 to 6 and all-call) in a PA system built
around the LBB 1990/00 Voice Alarm System. In addition to
table-top use, the unit’s special design allows it to be neatly
flush-mounted in desk tops. The Plena Voice Alarm Keypad
(LBB 1957/00) is an extension adding 7 additional keys.

Functions
On each call station it is possible to select 6 zones with the
possibility to connect up to 8 call station keypads
(LBB 1957/00) to increase the number of zones or zone groups
that can be selected. Each keypad adds 7 zone or zone-group
keys.
This call station features selectable gain, a selectable speech
filter, a limiter for improved intelligibility. Because the call station
provides a balanced line level output, it can be positioned up to
1000 m away from the controller, using CAT-5 extension cables.
Using shielded cable, the call station may also be used in a EMC
level 5 (heavy industry) environment.
Using dipswitches on the bottom of the call station, different
microphone gain levels can be selected as well as the call
station ID and the speech filter. Selected zones are indicated
with LEDs on the call station. Three additional LEDs give visible
feedback on the active state of the microphone and the system.
Green flashing means standby (chine is sounding), green
indicates microphone active, amber indicates that the system
has detected a fault (IEC 80649) and red indicates that the
system is in the emergency state.
