SIEMENS VCC2002-A1 Voice input/Output Card Instruction Manual

SIEMENS VCC2002-A1 Voice input/Output Card

The Model VCC2002-A1 Voice I/O card is installed into the FV2025/2050 Fire Voice Control Panel of the FS20 system. Together with the VCC2001-A1 Voice CPU card and one or more VCI2001-U1 Amplifier cards, it enables voice announcements to be made through the Fire/Voice system.

FEATURES
The principal features of the VCC2002-A1 include:

• The internal codec:
  • Converts analog audio from microphones, Mass Notification Systems (MNS), and other external sources into digital audio signals
  • Converts digital audio signals to analog for use in other parts of the system or with external equipment
• Attenuation and amplification of incoming audio
• Connections for optional remote microphones and voice switch modules
•  CAN repeater for externally connected modules (Channel 1 only)
•  Connections for two (2) configurable, simultaneous audio input channels and two (2) audio output channels, 1 internal and 1 external
• 24VDC power distribution, current limiting, and short circuit protection for modules connected to the Card Cage
• Operational status via LED displays
• Two volume controls (Future use)
• EMC compliant
• ROHS compliant and meets performance specifications within the industrial temperature range
• Can be used in the UL and ULC market

PRE-INSTALLATION

Before installing the VCC2002-A1 Voice I/O Card into the VCA2002-A1 Card Cage, set the jumpers on the card to either supervise or not supervise the input and output audio lines. Supervision refers to the automatic monitoring of signal lines for short or open circuit conditions. A supervised line will have an end-of-line (EOL) resistor at the end of the line to set a DC bias level. When the resistor is present, the DC voltage is at a certain value. This DC voltage level will change if the line is either open-circuited or shorted. This DC bias voltage is monitored by an analog-to-digital converter which enables the system to read all the voltage levels and determine if a short or open has occurred.
Figure 2 illustrates the locations of the jumpers on the Voice I/O Card and Table 1 lists the jumper settings that are used to activate supervision for the input and output channels. Both jumpers for each channel must be in the same position, either supervised or unsupervised, for the card to operate correctly.

Channel| Jumper ID| Jumper Position for Supervised Channel| Jumper Position for Unsupervised Channel
---|---|---|---
Audio Input 1| X401| 2-3| 1-2
 | X400| 1-2| 2-3
Audio Input 2| X403| 2-3| 1-2
 | X402| 1-2| 2-3
Audio Output| X601| 2-3| 1-2
 | X600| 1-2| 2-3

CAUTION: If supervised audio input lines are to be implemented, ensure that any connected  audio equipment is compatible with the 18VDC supervision voltage

OPERATION

Please refer to Figure 3.
The primary functions of the VCC2002-A1 Voice I/O Card are to:

• Interface with the VTO2004-U2/U3 Microphone Module and the VTO2001-U2/U3 Option Module (24 Switches).
• Provide analog to digital conversion of announcements routed to the VCC2001-A1 Voice CPU Card
• Provide digital to analog conversion of announcements routed from the VCC2001-A1 Voice CPU Card to external announcement devices.
• Distribute and supervise 24VDC power
• Provide DC supervision of external wiring
• Provide a CAN bus repeater functionality

Controls and Indicators

The VCC2002-A1 VCC I/O Card contains:

• Eight diagnostic LEDs
• One Power LED

All of these indicators are located along the card edge and visible through the Card Cage front cover.

Switch Inputs/Relay Output

Two general purpose contact closure inputs and one relay closure output are available to/from the VCC-I/O card. Either switch input can be used to indicate the presence of an external analog signal on the Channel 2 audio input (if used). The contact closure output is used to indicate that the output audio from the system is active.
Inputs (switch 1 and switch 2): A resistive (680Ω) contact closure must be provided by an external audio source. This closure may be connected to either switch input. This will indicate to the system that an analog audio signal is applied to the audio input channel. A closed contact indicates that the audio input to the channel is active while an open contact means that the audio input is inactive. A second set of contacts can be optionally used for other purposes as needed. Output: A relay contact output on the VCC-I/O card closes to indicate to an external device that the audio output is active. When the audio output is active, the relay contact is closed. When there is no audio output the relay contact is open. This is an isolated contact closure. The external connected device must supply its own voltage to monitor the state of the relay contact.

Remove electrical power prior to working on equipment.

To mount the VCC-I/O in the card cage:

1. Open the inner door of the FV2025/2050 Fire Voice Control Panel.

2. Unscrew the latch on the center-bottom of the Card Cage front cover and slide the cover up until it clears the Card Cage assembly.

3. Refer to Figure 5. Holding the VCC2002-A1 so the two volume control potentiometers are on top of the card, gently insert the card into the backplane connector marked X201 (furthest left position of the card cage). Use the raised channel guides on the inside top and bottom of the Card Cage to guide it into place.
   CAUTION: When inserting the VCC2002-A1 into the backplane connector, avoid using the top and bottom of the card cage for leverage. Instead, push gently on the center of the molded plastic card handle until the card snaps into place. Be sure that the card is perpendicular to the front of the Card Cage and is positioned between the two indented metal cards guides in the top and bottom of the Card Cage. The card needs to be between all three sets of card guides as it is slid into place to correctly mate with the backplane connector.
   WARNING: To avoid damaging the VCC2002-A1 card or the backplane connector, DO NOT FORCE THE CARD INTO POSITION.

4. Replace the Card Cage cover by re-inserting it into the top of the cage and sliding it downward until it reaches the bottom of the assembly.

5. Screw the latch back into the Card Cage cover.

Removing the Voice I/O Card from the Card Cage

1. First remove power from the Card Cage.
2. Unscrew the latch on the center-bottom of the VCA2002-A1 Card Cage front cover and slide the cover up.
3. Grip the VCC2001-A1 Card by the molded plastic card handle and pull the card gently out of the backplane connector.
4. Replace the Card Cage cover and reinsert the latch.

WIRING

All signals to/from option modules or other devices are connected to the VCC-I/O card via Card Cage Connectors X401, X402, X403, and X102 located on the VCA2002-A1 Card Cage.
