Place the Feather board in it's case on top of the freezer and run the door sensors and motion sensor through the grate.
Hold the door sensors in place and trace the inside corder with a permanent marker, repeat for the 2nd door.
Attach the 15ft power cable to the alarm. Leave the extra lengths coiled up on the top of the freezer and then plug it in to a USB wall charger (5v 2a). The alarm will beep when power is applied.
