A.
It defaults to no access.
B.
It defaults to being unlocked.
C.
It defaults to being locked.
D.
It defaults to sounding a remote alarm instead of a local alarm.
Explanation:
B: A fail-safe setting means that if a power disruption were to affect the automated locking system, the doors would default to being unlocked. A fail-secure configuration means a door would default to being locked if there were any problems with the power.
