Figure 2-12: VIP2 Keypad
When the VIP2 is used as a stand-alone device, a 4- to 8-digit key code is entered for each user
with the KEY command. The ACU reads this key code as if it were generated by a command
key being presented to a proximity reader. However, when the VIP2 is used in conjunction with
a proximity reader, a 4- to 5-digit personal identification number (PIN), generated by the ACU,
is used in place of the key code.
If a user becomes aware of an error when entering code numbers, pressing either the star (*)
push-button or the pound (#) push-button will abort the process and the code may be reentered.
The user may have from 0 to 5 retries before an ACCESS DENIED report is generated. The
number of retries is defined with the SYSTEM command as is the grace time for keypad entry.
If 1 through 5 is selected, the center LED will blink on and off, indicating that the PIN entry can
be retried.
