BOSCH PAVIRO - PVA-CSK Call Station KIT

Architects’ and Engineers’ Specifications

The call station KIT shall be the PCB version of the desktop Call station. It shall bedesigned to enable the creation of a custom call station. The Call station KIT shall

include a PCB with Eurosyle connectors and a raphical display. It shall be possibleto connect a dynamic or electret microphone to the Call station KIT. !ddress andcanbus settings shall be done by "IP switches on the board. The user shall be able to

freely decide what to connect# illuminated $C%display and&or a loudspeaker'

$eds&Bulbs and or buttons.The operation status shall be permanently supervised by the system controller. The

call station KIT shall provide () free programmable user functions via the $E"&Bulbconnectors. The user shall be able to connect $E"s or *+, industrial bulbs to the

$E"&Bulb connectors. -sing Bulbs shall reuire an additional *+, power supply# itshall be possible to connect and additional power supply via eurostyle connectors on

the PCB.It shall be possible to add a ma/imum of two additional supervised emergency

buttons to the Call station KIT. 0ptionally1 it shall be possible to add a key switch to

lock or enable call station KIT functions with a key switch.

The call station KIT shall have the following features#

• 2ive menu&function keys 3pre%programmed4 5 five buttons shall provide each

( $E"&Bulb.

• () function and speed dial buttons 3customi6able41 each two $E"&Bulb

connections per button function shall be available.

• Button functions shall be programmable as#

o 7one select1 source select1 level control1 emergency on&off1 message

on&off1 failure acknowledge&reset.

o switching output trigger on&off or 8 to (8,1 select scheduled events1

• :upervised microphone1 with limiter and a speech filter for e/cellent speech

intelligibility.

• C!T) cable for data and audio connection to controller 3can bus1 up to (888

meter4.

• It shall be possible to daisy chain + call station KITs.

• It shall receive audio and operational control signals from the controller1 and

shall report its status to the system controller.
