Chapter 3 Buzz E. Smoke Alarm
The Smoke Alarm has moving eyes, eyelids, arms, eyebrows, and a moving mouth. These
functions are operated by individual servo motors in the Smoke Alarm itself. The signal comes
from the main control board to operate these functions. The signal wire that comes from the
main control board goes to a servo board inside the Smoke Alarm. The servo board decodes
the pulse train signal into individual signals for each servo motor. The mouth servo is located in
the Smoke Alarm with a rod going up to the mouth itself. The mouth motor moves in sync to the
music or in sync to your talking if you are using the headset microphone.
When you put the Smoke Alarm on top of the base unit you have to screw in the round knobs to
his feet. Always make sure these are snug before operating. The two wires coming from Buzz
connect to two wires in the base unit. The wires are color coded to make it easy to match them
up. Be careful with these wires and connectors when removing or installing the Smoke Alarm.
Be especially careful with the arms when transporting Buzz.
