REED SWITCH
A reed switch is used to monitor door state. When the
door is closed magnetic force pulls the reed to its
contact and closes the circuit which turns the light and
display off. When the door is open the reed pulls away
from the contact and opens the circuit. If the door is
left open for longer than 5 minutes, the switch will
trigger an error code and set an audible warning.
