Siemens VCI2001-U1 Voice Amplifier Card, Installation Instructions

INSTRUCTIONS VCI2001 U1 Voice Amplifier Card Model VCI2001 U1 Voice Amplifier card of the FS20 Voice system provides one speaker zone with speaker lines and one Class D audio amplifier capable of operating at either 25 VRMS or 70 VRMS Voice Amplifier cards can be configured in either a 1 1 or 1 Many redundancy configurations and can wired to drive one Class A speaker line one Class B speaker line or a dual interleaved Class B line The Voice Amplifier cards can also be wired to supervise and power HCPs in one Class A or Class B configuration For details refer to the HCP installation instructions P N 315 034860 principal features of the VCI2001 U1 include Class D audio power amplifier Two selectable output voltages 85 overall efficiency under full load 80 overall efficiency under full load High voltage supply topology Standby operation with self check when idling modes Provides supervision of field wiring EMC shielded Can be used in UL and ULC markets Self monitored for hardware failures with automatic fallback to degraded 1 Amplifier Card installing the VCI2001 U1 Amplifier Card into the VCA2002 A1 Card Cage set the jumpers on the according to Table 1 See Figure 2

receives control data and digital audio the VCC2001 A1 Voice CPU Card converts the digital audio back to analog and amplifies it broadcast over local loudspeakers The Voice Amplifier output section includes two identical for speaker lines each of which are capable of supporting one Class A one Class B one Dual Interleaved Class B speaker line The Voice Amplifier is protected from short circuit and The Voice Amplifier circuit supervises the speaker line for short open circuit and fault The field wiring supervision system uses DC current and an end of line resistor in with AC coupled speakers

the VCI2001 U1 so the transformer is on the top of the card insert the card into the backplane amplifier slots VAC101 VAC102 VAC103 or see Figure 6 Use the raised card guides on the inside of the top and bottom of the Cage to guide it into place inserting the VCI2001 U1 card into the backplane connector avoid using the and bottom of the Card Cage for leverage Instead push gently on the center of molded plastic card handle until the card snaps into place Be sure that the card perpendicular to the front of the Card Cage and is positioned between the two metal card guides in the top and bottom of the Card Cage The card needs be between all three sets of card guides as it is slid into place to correctly mate the backplane connector avoid damaging the VCI2001 A1 card or the backplane connector DO NOT THE CARD INTO POSITION Referring to the System Design documentation repeat Step 3 for each VCI2001 U1 Card to populate each of the VAC positions on the backplane Additional VCI2001 U1 positioning instructions are provided in the VCA2002 A1 Card Cage Installation Document ID A6V10370410 Replace the VCA2002 A1 Card Cage cover by re inserting it into the top of the cage and it downward until it reaches the bottom of the assembly Screw the latch back into the Card Cage cover the Voice Amplifier Card from the Card Cage First remove power from the card cage Unscrew the latch on the center bottom of the VCA2002 A1 Card Cage front cover and Grip the VCI2001 A1 Card by the molded plastic card handle and pull the card gently out of the cover up backplane connector Replace the
