Can you put a key lock on a manual fire alarm pull in a mental hospital?

Generally, key locks are not recommended for manual fire alarm pulls because they can impede quick access in emergencies. Fire codes and regulations typically require that manual pull stations be easily accessible and operable by anyone, without the need for special keys. In a mental hospital, safety protocols must prioritize rapid response to fire alarms to protect all occupants. However, specific regulations may vary, so it's essential to consult local fire codes and standards.
