4B. Alternate Power (Optional); Location Of The Media Connector - Lightspeed TOPCAT Installation Manual

4b. ALTERNATE POWER (OPTIONAL)

When electrical AC power is not available above the ceiling for installation with
the TOPCAT, there is an alternative method for supplying power to the TOPCAT.
NOTE: there are two DC power connectors for connecting power to the
TOPCAT. Both connectors perform the same function. Use the internal DC power
connector located on the amplifier module when AC power is connected directly
to the TOPCAT. Use the connector access located on the outside of the TOPCAT
when using the optional DC extension cable.
1. Disconnect the AC power plug and the DC output cable from the factory
installed 24V 2.5 amp power supply, then remove the metal bracket securing
the power supply inside the TOPCAT.
NOTE: The 24V power supply brick must be placed in the room below the
suspended ceiling. Faceplates and electrical boxes should be provided by the
installer as required.
2. Find the 50' DC extension cable and plug the female connector into the side
port on the TOPCAT. Use the wire anchor supplied with the cable to secure
the cable to the side of the TOPCAT chassis. Use the cable tie provided to
secure the end of the power cable remaining in the TOPCAT to the U-bracket
originally housed the power supply. This cable should not touch the flat panel
speaker when the door is closed.
3. Route the DC extension cable across the ceiling and to the closest standard
AC power outlet. Cable routing should follow all local electrical codes and
installation procedures. (If the DC extension cable is to be run inside the wall,
install a mud ring or electrical box in the wall close to the AC power outlet. If
the DC extension cable is run on the surface of the wall using wire molding,
then mount a surface mount electrical box to house the connection of the DC
extension cable and the power supply.)
4. Plug the DC extension cable end of the 24V supply into the power extender
cable.
5. Plug the AC power cord into the power supply and into the standard AC
power outlet.
NOTE: the 50' DC extension cable is plenum rated, suitable for air handling
spaces.

5. LOCATION OF THE MEDIA CONNECTOR

Choose a location for the Media Connector (MC) that is convenient to the
classroom audio sources and power supply.
The MC can be placed on a counter or wall mounted. Determine the best
location for your room. Use the guidelines below when selecting the site.
NOTE: The MC does not require a direct line of sight to the TOPCAT. However it
functions best when no obstructions are between the two devices. Do not place
in an enclosed metal cabinet.
A. COUNTER OR DESKTOP
• 3-6 feet off of the floor to allow for
good transmission.
• Not enclosed in a metal cabinet or
otherwise obstructed.
