Fail-Safe and Fail-Secure
Locks are categorized based on their response to power loss. Choose the type that best suits your needs:
- Fail-Safe Lock: Automatically unlock during a power loss, ensuring safe egress. Ideal for emergency exits and building entry/exit doors.
- Fail-Secure Lock: Remain locked during a power loss, maintaining security for restricted areas such as data storage rooms.
