3.4 Call station
In total 8 call stations (LBB1956/00) can be connected
to the controller for making business calls. The rearside
of the controller provides two RJ45 connectors for the
connection of the call stations. To connect call stations,
refer to section 4.14.
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).
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.
3.4.1 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.
