Step 9Wiring the components: part 3 (Armed circuit)
After you have the negative sides of both LEDs connected, we need to attach the positive side of the red LED to the armed circuit.
This will be achieved through the use of a short jumper connecting the currently unused tab on the pushbutton switch to the positive lead of the LED. The negative side of the LED is already connected to the speaker terminal via the resistors to the wire leading to the terminal blocks.
Cut 12 short lengths of wire, stripping each end about 1/4". Slide one end all of the way through the hole in the pushbutton switch tab, and lean the other against the positive lead of the red LED. Solder the jumper to the pusbutton switch tab and the positive lead of the LED, then snip off the extra wire on the LED side only. Leave the extra sticking out through the switch tab, since we will be connecting the main armed circuit to it. Do this for each of the 12 channels.
Now it's time to connect all of the individual channels to each other and to the armed circuit. Cut 8 more wire jumpers, once again stripping 1/4" off of each end. Use red wire if you want to keep things visually organized. The red jumpers will be connected between the extra wire on the black jumpers so that the left sides of the pushbutton switches are all connected to each other.
Connect all of the channels to each other in each column, then bridge each half of the columns together. The middle two will have a second jumper on the top channels (4 and 7) in each column that will run directly to the toggle switch. See the last picture below to clarify this.
Now the armed circuit is complete.
