The vault door fingerprint access control system provides three alarm functions to ensure on-site security for the vault.
1. System self-protection alarm: The anti-pry alarm is triggered when the fingerprint recognition device is forcibly pried open. A disconnection alarm is generated when a wiring break occurs between the fingerprint processing unit and the lock control unit, providing an alert indication.
2. Unauthorized door-opening alarm: This includes alarms triggered by door openings without fingerprint verification and by multiple failed fingerprint verification attempts. Door-opening timeout alarm: This is an alarm generated when the door remains open beyond the prescribed time limit.
3. Coercion Alarm: When multiple fingerprints are enrolled, one of them can be designated as the “alarm fingerprint.” If the alarm fingerprint is forcibly used to unlock the door, the system will automatically transmit a covert alarm signal at the moment of unlocking, thereby effectively safeguarding the life and safety of the person under duress.
