System Operation
The Push-to-Talk microphone is used for live pages.
The microphone has priority over message playback
paging. Pressing the Push-to-Talk switch on the
microphone will activate the audio output and
override (and CANCEL) any message playback in
process.
A group of eight (8) front panel buttons with
associated LED’s are used to activate stored
messages. When a message is activated, the LED
will indicate the status. If the message is playing,
the LED will illuminate. Messages are not
chainable. A message must be finished before an
additional message may be activated. If a message
button is pressed while a message is playing the
original message will cancel.
A “MESSAGE CANCEL” button is available to
cancel any message playing.
Using the program tool, all messages can be
programmed for the following play scenarios:
1 play per button activation
2 plays per button activation
3 plays per button activation
Continuous plays per activation (cancelled via
“MESSAGE CANCEL” button)
Programming Voice Messages
A serial port (RS-232) is provided to upload and
download voice messages. The program tool
provides all editing and message processing (AGC,
response shaping, wave file conversions, etc.).
The final format is standard 8 bit uLaw at 8kHz
compressed format.
Although it is possible to upload and download
during system operation, it is recommended to
perform this function when the system is not in use.
This insures that messages will not be corrupted
during a download of upload. After message write
remove battery and DC power momentarily.
Total voice message storage is 8 minutes and there
are no other restrictions on lengths of individual
messages. It is possible to record tones, signals,
etc. that will operate in the voice band range. For
additional programming information refer to the
Message Control Panel Program Tool Help Menu.
System Fault Monitoring
The main audio channel has an inaudible tone
present whenever a page or message is not active.
This tone will verify the integrity of the audio channel
from the microphone to the audio output. In addition
the audio and power pairs of the speaker line are
monitored for shorts, opens and grounds. A V-9999
End of Line device is used to terminate the speaker
line.
Note: For Full System Supervision, Use Only
Valcom One-Way Supervised Speakers And
Horns With The Page Panel.
Proper operation of the voice memory flash device is
monitored by continuous reading a fixed segment of
the memory. This insures the flash memory integrity
as well as the circuitry that attaches it to the DSP
controller. It will detect defective components and
interconnection faults as well as actual memory
failure.
In the event of a system, wire or power failure, the
“System Fault LED” will illuminate and an audible
alarm will sound. The audible alarm may be
silenced by pressing the “Cancel Audible” button,
however the “System Fault” light will continue to
illuminate until the fault has been corrected. A 9 Volt
battery located on the back of the Page Panel
provided the necessary power to operate the fault
circuits in the event of a power failure. The 9 Volt
battery is monitored and a system fault will occur
when the battery voltage drops. A contact closure is
available to signal a remote monitoring panel when a
system fault occurs.
Installation
Figure 1, shows microphone, message activate and
fault indication control locations. Figure 2 shows
remote message activate terminal connections
output connections, programming and power
connections located on the back of the message
panel. Figure 3 shows a typical connecting
arrangement and other feature connections.
Referring to Figure 3, connect 24VDC as indicated.
9479803
Using an RJ-45 connector, connect speaker audio
(Tip and Ring) and speaker power to board
mounted connector as shown on connecting
diagram.
All connections should be made to the mixer and
double-checked prior to connecting DC power.
Refer to Figure 3 to connect the message active
contact and remote activation of the messages. A
remote mounted connecting block will be required
to access these connections. Figures 4, 5 and 6
show connections to various types of Valcom
equipment.
Programming the Message Panel
Refer to the programming guide included with the
message panel documentation.
System Troubleshooting
There are 4 LED’s located on the PC board for
system troubleshooting. They are:
• LED D9 Mic. Switch Fault (ON = a fault is
being detected)
• LED D10 DC Fault (low battery or internal
monitoring
System fault) (ON = a fault is being detected)
• LED D11 Audio loop back fault (ON =
Fault in Mic. audio or 30Hz amplifier loop
back)
• LED D12 Flash Memory Error (ON =
Flash checksum failed
TECHNICAL ASSISTANCE
When trouble is reported, verify the unit is
turned on and there are no broken
connections leading to the unit.
Assistance in troubleshooting is available from
the factory. When calling, you should have a
VOM and a test set and call from the job site.
