distributed amplified paging

Installation/Connection Cabling Category 3 or 5 twisted pair cable is recommended for all Valcom  distributed amplified paging installations.  Screw terminals are provided  for the basic  connections.  RJ45 jacks are provided for chaining multiple  V-9964 units together.  Removing the narrow right side panel of the  V-9964 provides access to  controls, connections and option switches.  To remove the panel, loosen the two screws holding  the panel in place and lift the panel. Mounting The V-9964  may be wall  mounted or  rack mounted in a  standard 19  inch equipment rack using the brackets included. Connections See Figure 1 for a connection diagram. Tip 1, Ring 1 INPUT 1 is the normal Primary or  Call Stacker system input, and connects to a Loop Start Trunk Port, 600 Ohm Page  Port or some  Valcom Page Controls.   Note: Do not connect to a C. O. Line. Control Input 1 Provides  contact closure activation when  using a Page Port. Tip 2, Ring 2 INPUT 2 is the Override page or Call Stacker line two input.  If desired, connect this to  a second  Loop Start Trunk Port or Page Port. Note: Do not connect  to  a C. O. Line. Provides  contact closure activation when  using a Page Port. Background Music Input Connection for external line level music source (Example: V-2952, FM Tuner). NOTE:  If   using multiple V-9964 units in a chained configuration, all speakers must connect to  the output of  the last  unit   in the chain. Line Out Output connections  to Valcom amplified speakers or 70 Volt amplifier Aux input. Loop Out Connects to Tip and Ring  input on a Valcom multi-zone page control unit. Expansion In RJ45 connection from the previous  V-9964 in a chained configuration.   Expansion Out RJ45 connection to the next V-9964 in a  chained configuration.  Closing a switch  connected to pin 7 and pin 3 of  either Expansion In or Expansion Out will hold  all queued recorded messages, on all linked V-9964s.  During  this time, additional messages may still be recorded into the            V-9964(s).  Once the  switch is opened,  all queued messages, including DTMF, will  play in their entirety. Abort To abort a message during play, connect an external relay  contact across the two abort terminals. NOTE: To abort a message during the record sequence, press any  DTMF button on  the dial pad of the access telephone. Relay  Closure Outputs (PLAY)  PLYSW and PLYMK Normally open relay contact that closes  while a message is being broadcast. (RECORD)  RECSW  and  RECMK Normally open relay contact that closes  while a message is being recorded
