Below is a schematic diagram of my canopy alarm. I realize that there are simpler circuits. I chose to use the CD4011 because I only had one wire going to the canopy switch and didn't want to run another one. Also, the CD4011 outputs 5 volts needed by the voice recorder. When activated, the voice recorder plays, "CANOPY OPEN". The pilot knows immediately what is wrong and does not have to figure out what an alarm light or buzzer means.
