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.
