INSTALLATION INSTRUCTIONS Model VCC2002-A Voice input/output Card The Model VCC2002-A Voice I/O card is installed into the FV2025/2050 Fire Voice Control Panel of the FS20 system. Together with the VCC200-A Voice CPU card and one or more VCI200-U Amplifier cards, it enables voice announcements to be made through the Fire/Voice system. FEATURES The principal features of the VCC2002-A include: The internal codec: o o Converts analog audio from microphones, Mass Notification Systems (MNS), Global Management Systems (Desigo CC) 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 Connections for two (2) configurable, simultaneous audio input channels and two (2) audio output channels, internal and 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 EMC compliant ROHS compliant and meets performance specifications within the industrial temperature range Can be used in the UL and ULC market Figure VCC2002-A Voice I/O Card PRE-INSTALLATION Before installing the VCC2002-A Voice I/O Card into the VCA2002-A 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 endof-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 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. A6V097774_en--_a

CAUTION: If supervised audio input lines are to be implemented, ensure that any connected audio equipment is compatible with the 8VDC supervision voltage. OPERATION Please refer to Figure. The primary functions of the VCC2002-A Voice I/O Card are to: Interface with the VTO2004-U2/U Option Module (Microphone) and the VTO200-U2/U Option Module (24 Switches), if applicable, and other external devices, such as CD players. Provide analog/digital conversion of announcements routed to the VCC200-A Voice CPU Card Provide digital/analog conversion of announcements routed from the VCC200-A to the external announcement sources.

Controls and Indicators The VCC2002-A VCC I/O Card contains: two audio level controls for Input and/or Input 2 eight diagnostic LEDs one Power LED All of these controls and indicators are located along the card edge and visible through the Card Cage front cover. NOTE: The audio level control does not affect audio levels that originate from external microphones. Adjust the audio input levels on Input and/or Input 2 by inserting a small screwdriver through the proper opening on the front panel and turning it clockwise to increase, or counter-clockwise to reduce the level. Table 2 defines the functions of the nine LEDs. Audio Activity Inputs/Outputs Contact closure inputs and outputs are available to/from the VCC-I/O card. They are used to indicate the presence of an external analog audio signal on the inputs to Channels or 2 and that the output audio from the system is active. Input. One set of contacts must be provided by each external audio source that is connected to either the Channel or 2 input to indicate when an analog audio output is applied to the 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. Output. A relay contact on the VCC-I/O card closes to indicate to external devices that the audio output is active. When the audio output is inactive, the relay contact is open. This is an isolated contact. The external connection must supply its own voltage to determine the state of the relay contact.

MOUNTING Remove electrical power prior to working on equipment. To mount the VCC-I/O in the card cage:. 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. VOLUME CONTROL POTENTIOMETERS CARD HANDLE Figure 5 VCC2002-A Voice I/O Card Showing Handle and Volume Controls. Please refer to Figure 5. Holding the VCC2002-A so the two volume control potentiometers are on top of the card, gently insert the card into the backplane connector marked X20 (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-A 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-A 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.
