Function: Enables the detection LED of the optical barrier This command can be used to
allow for biometric identification simply by placing a finger on the sensor.
The optical barrier is self-managed by default; therefore this instruction is useful to:
• Activate biometric identification after reading a proximity card.
• Force the fast recovery of the optical barrier after a biometric identification (the
normal recovery time is set using the CFG-UI_OPT_T_GUARD Byte of the
configuration, see
Subsection 8.1.3. or is indefinitely suspended using the
Disable optical barrier instruction).
9.6.24. Disable optical barrier
Function: Disables the detection LED of the optical barrier There are several reasons for
using this instruction:
• When the scanning of a finger print has started to prevent new warnings.
• In the case of 1:1 identification, the user is expected to start identification using the
proximity reader.
• In the case of presence control, the user is expected to press F1 or F2 prior to
biometric identification.
