The system supports both Normally Opened Lock and Normally Closed Lock. The NO Lock (Normally
Opened when powered) is connected with 'NO' and 'COM' terminals, and the NC Lock (Normally Closed
when powered) is connected with 'NC' and 'COM' terminals. The power can be shared with the lock or can
be used separately for the lock, as shown in the example with NC Lock below.
