A call station has 6 Zone Select buttons, one All Call
button and a PTT button. The Zone Select buttons can
be configured, for selecting zones or zone groups within
the system. The PTT (Push To Talk) button can be
assigned a pre- and/or a post-chime. Each call station
can be assigned a priority level between 1 - 6. If a Plena
Voice Alarm System serves more than 6 zones, it is
possible to connect one or more call station extension
keypads to a call station (see section 3.4.1).
Note
Refer to the Configuration Software Manual
(9922 141 10381) for details about configuring
a call station.
In accordance with IEC60849, the controller disables all
call stations during an emergency call (see section 6.7)
or an active emergency trigger (see section 4.7.1). A call
station is not supervised.

Extension keypad

Each router (see section 3.3) that is connected to a
controller, adds 6 extra zones. To be able to select all
these extra zones from a call station, it is possible to
connect at maximum 8 extension keypads (LBB1957/
00) to a call station. Each call station extension keypad
provides 7 extra Zone select buttons, for selecting zones
or zone groups within the system. A call station
automatically detects how many keypads are connected.
To connect extension keypads, see section 4.14.1.
