1. Intr oduction
1.1 Sy s t em o v er v i e w
The PMX-CSK Call Station Kit contains a printed circuit board (PCB) that can be
used to make custom-made call stations (e.g. a fireman’s panel) and belongs to
the PROMATRIX 8000 product family.
PMX-CSK is the kit version of the DPC 8015 with some small kit spec
differentiations. Eg, the PMX-CSK provides a connection to the
go o s e neck
microphone as known from the call station DPC 8015 but also provides a
connection to connect to a Dynamic EMERGENCY microphone like the
BOSCH LBB 9081. It provides
15 programmable contact closures and 5
p r ep ro gramm e d contact closures for eventual menu access . Up to 3 alarm
keys or key-locked switches can be
connected . The PMX-CSK employs a
lighted LC-display (122 x 32
p i xel).
The call station includes the
following f e at ure s :
•
condenser or dynamic microphone with pre-amplifier and compressor / limiter circuitry
• freely programmable k ey- as signment
• additional alarm keys or key-locked switches can be connected
• connection of an external PTT-microphone or audio so ur ce
• l o u d s p e a k e r connection
• high resolution L C -disp l a y
• user menu allows additional parameter settings at the call station kit
• microphone and line sur ve i ll ance
• error indication via LED connections, loudspeaker and text messages at L C -d i s play
• all functions are pr ocesso r - con t r o ll ed
• processor surveillance via watchdog f u nc ti on
• configuration data is stored in non-volatile FLASH RA M
The call station kit is
processor-controlled and extensive monitoring
functio n s are provided. The watchdog function monitors the processor
system.
T h e line surveillance function recognizes any line-interruption
and/or
sh ort-circuits in t h e audio and CAN cabling. The microphone
surveillance and the PTT button surveillance checks
functionality and
recognizes any
interruption and/or s h ort- ci rc uit.
The IRISNe t software allows comfortably configuring t h e call sta t io ns kit. Its
graphic, dialogue-oriented user interface offers effortless assign of key
func tions, priorities, options, and many other call station kit f u nc ti on s.

se
t - ting up, fault messages including precise device / module
specification, e t c.
STATUS ME SSAGES
During error free operation of the PROMATRIX 8000 system the LC-
d
i s p l ay shows t h e name / description of t h e call station kit in line 1 and the
current da te and time in line 2.
ERROR
ME SSAGES
An error within the PROMATRIX 8000 system is indicated by the call
statio n kit in following wa y:
•
The FAULT LED output is toggling on/off and a warning signal i s activated via the lou d s p e a k e r.
• The description of the error is indicated via the L C -disp l a y .
•
By activating the ESC input, the acoustic warning output signal stops and the FAULT LED output
ch anges is set permanently on.
If another error occurs in the system, the
ESC input has to be activated again.
•
The FAULT LED is activated as long as the error in the PROMATRIX 8000 system ex ists.
The error
indication and the warning signal must be configured in the IRIS-
Ne
t sof t war e .

3.2 Operation mode
After power on the call station kit is in operation mode. For configuring t h e
ca
ll station kit the setup mode is used. Several key functions differ between
setup
mode and o p e r a t i on mode, see following t a b l e.
Operation mode (default configuration) Setup mode
Up_K
( ↑ Up key )
The UP input turns the system‘s power on or off.
Turning the power on can take several seconds. The
LED output toggles on and off while the system boots.
The UP
LED output is steadily when the system is
operational. To p r e ven t inadvertent erroneous
operating closing the up input
for at least 3 seconds
is
necessary when turning the power off. It is also
possible
to prohibit the o p eratio n of the up input during
the configuration procedure.
In setup mode this
input is used to select
the previous par a me t e r/
menu it e m .
ESC_K
( ESC key )
Closing the ESC input confirms an error in th e
PROMATRIX 8000 system and cancels an output a l arm
output signal.
This input is used to
cancel the editing of a
parameter or to move
upwards
in the menu
tr ee .
Down_K
(↓ Down key )
Closing the Down input stops a currently running a u d i o
signal (chime, alarm, text). Use the
IR IS-Ne t sof t w a r e
for configuring the input functionality in detail.
In setup mode this
input is used to select
the next param e t e r/ menu
item.
DE L_K
( DEL key )
The DEL input allows the selection of all pr og r a mm e d
areas at once for transmitting messages, chime or
alarm signals, vocal messages, or to assign p r o g ra ms.
On time pressing selects all areas. The corr espon d ing
selection
LEDs and the DEL LED outputs are set .
Subsequent closing cancels (clears) the sele ction .
Following modes are available in the IRIS- Ne t sof t w a r e
for this input :
•
Toggle between all and clear
•
Select A ll
•
Deselect A ll
De le t es the c u rr entl y
selected parame t e r .
Return_K
(↵ Enter Key)
The enter input activates a message for pre-selected
ar e a s or groups. The LED output toggles on and off when
one or several
ar e a s are busy or when an event with
higher priority
se tt ing interrupts the output message.
The optional toggle
mode of the key is configured
via
IRIS- Ne t .
Confirms the p a rame t e r
change or selects the
highlighted menu item.

Operation mode (default configuration) Setup mode
Sx_K
Selection inputs
The 15 switch inputs with corresponding (green /
yellow) LED outputs are used to pre-select areas or
groups
for the reproduction of messages, chime or
alarm signals, vocal messages, or to assign programs
(close this input once
= on, subsequently closing again
= off). The Sx_LED outputs ind i c a t e the momentary
selection status. It is also possible to
assign special
functions or no function at all (no function a ssigne d ) to
those inputs. Assigning functions is performed d u ring
the configuration procedure via IR IS-Ne t ..
Enter the co rr es pondin g
number of the input .
SELECTIVE C AL L
The user can launch calls or
announcements into freely selectable areas
or gro u ps.
Activating a single or several
selection inputs defines areas or groups wh er e
a call is launched
into – corresponding green LEDs outputs will be set . By
activating
t h e key input of an already pre - se lec t ed line once again
deactivates that line and the corresponding green LED output goes off. If
the Sx_LED (yellow LED) output belonging to a Sx_K input (se
lec t ion)
contact is activated, the corresponding area or group is busy.
After making a
selection, activating the enter input ignites the call. Prior
hereto , the corresponding LED output allows checking wh e t he r all
lines and the call
station kit input ar e actually free. If single lines or the
terminal input are busy with lower prio ri ty transmissions, t h e enter (return)
LED will be toggle slowly. Whilst making an
a nno uncem e nt is possible, this
will interrupt
any other transmitted event. If single lines or t h e terminal
input
are busy with higher priority signals, the enter LED output will toggle
f
ast and t h e calling attempt is ignored .
The enter LED output is stable on during the transmission of an
announcement. The enter input has to be closed during the whole
announcement.
The enter
LED output starts toggling during an announcement when one or several
areas are busy and / or when an eve
n t wi th a higher priority interrupts
the announcement.
In those cases it is necessary to repeat the
announcement..
Until the user makes any changes, the defined selection
stays
mem o ri zed, even after deactivating the enter connection. Closing the DEL
button two times des elects the entire selection.
COLLECTIVE CALL
The
announcement is launched into all areas of the entire installation .
The
procedure is similar to making a se lec t ive call. First, all areas of the
i n stallation are selected by activating the DEL input. Activating the enter
input activates the collective call.
During
t h e transmission of a call, all area an d/ or group LED outputs as well as
the DEL LED output will
be activated . The enter input has to be activated until
the end of the
announcement. Busy LED output a ctivation is equivalent to the
selective call
.
