2.
The unit emits a short beep and the right green LED flashes. This
shows that the unit is waiting a user to place a finger on the
sensor.
3.
The users place their finger on the fingerprint sensor. When the
unit finds a match, it emits three short beeps and the two green
LEDs to indicate success.
If the user does not place a finger within 10 seconds, the unit
returns to Standby mode and the user must restart the
identification procedure.
4.
The unit sends the data to the access controller, according to its
configured transmission format. The unit then re-enters Standby
mode.
6.4.2
Invalid Card or Fingerprint Read
An invalid card or fingerprint read can occur when:
There is an error in fingerprint presentation (for example, a user
places the finger incorrectly)
There is a mismatch between the fingerprint and the template
(for example, a user presents the wrong finger)
An invalid card read can occur when the card is not verified. When a
card or fingerprint read is invalid, the following sequence occurs:
1.
If the fingerprint is wrong or the card (in 1:1 mode) is invalid, the
two LEDs turn red and the buzzer emits a long, low beep. The
user can then re-attempt finger presentation.
2.
Based on the Lockout mode configuration (Section
6.5), several
invalid reads within 30 seconds puts the unit into Lockout mode.
If there are fewer than the preconfigured number of invalid card
or fingerprint reads within 30 seconds, the unit enters Standby
mode.
