When this feature is activated, the terminal waits for an acknowledge signal
(LED IN) from a Central Access Controller system, before granting the access.

1.If the user is recognized the MorphoAccess

®

 sends the user identifier to the

controller.

2.The MorphoAccess

®

 waits during an adjustable timeout, for the closure of a

switch between LED1 and GND, or between LED2 and GND.

3.The controller checks the user's access rights.

4.The controller sets LED1 to GND to grant the access or sets LED2 to GND
to deny the access  In case of time-out, the access is also denied..

5.The "wait for access request" mode restarts only when LED1 and LED2 are
reset to default state again.
