means A fortified, lockable room built into a house where occupants can hide and call for help during a break-in or attack.

from From panic, which traces to the Greek god Pan, said to cause sudden, groundless terror in travelers and flocks who heard strange noises in lonely places — his name giving us 'panic' for that irrational, infectious fear. 'Panic room' itself is a modern compound, popularized in the early 2000s partly by the film of that name, describing a safe-room concept that security-conscious homeowners had already begun installing.
