3.4 Power
Connect the AC power adapter to the 12 VDC jack on the back of the 2743. This is shown as
Item 9 in the picture on Page 7. Plug the AC power adapter into a wall outlet. Please be sure this
outlet is not controlled by a switch.
3.5 Status Indicator
Verify that the status indicator (Item 8 Page 7) is blinking. For External Paging, the indicator
should blink twice rapidly every few seconds. This shows that power has been connected to the
unit.
3.6 Amplifier Connection
The 2743 connects to an external amplifier through the external wiring block and 8 wire modular
cord included with the unit. The external amplifier is then connected to the wiring block. The
steps for amplifier connection are as follows:
1. Locate the 8 wire cord and the external wiring block. The 8 wire cord is black and is
approximately 6 inches long.
2. Connect the cord to the jack on the back of the 2743 labeled “TO WIRING BLOCK.”
3. Connect the other end of the cord to the wiring block.
4. Install the amplifier and speaker by following the manufacturer’s directions.
Amplified speakers may also be used with the 2743. In this case no amplifier is
needed.
5. Connect the amplifier input to the wiring block. If the amplifier input level is less than
-25 dBm, connect the amplifier to the BLUE and BLACK wires. If the amplifier input
level is greater than -25 dBm, connect the amplifier to the WHITE and BROWN
wires. No cables are included for this connection. They must be supplied by the user.
