VP Keypad Access Device
27
rev. 7-2017 114A3868.E
If the unit is not able to read the card correctly through the slot,
or if there is an error on the card, the following message will be
displayed:
Sorry -
Try Card Again
When the card is read, the keypad will go through the security
checks described in “Security Checks” on page 27. If all security
checks pass, the keypad sends the card data to the controller and
waits for a response. The message on the display will change to
the following while waiting for a response.
* PLEASE WAIT *
When the keypad receives a response from the controller it will
display the response message. The messages received from the
controller vary depending on the type of response. The various
response messages are shown in the Access Response Messages
section.
Security Checks
The VP performs a series of security checks before allowing
entrance. These checks are used to prevent unauthorized access
attempts. When a customer uses an access code, the checks are
performed as soon as the code is entered. If the customer uses
a card, the checks are performed as soon as the card has been
swiped in the magnetic stripe reader.
Communications Check — the first item checked is
communications between the units on site and the controller.
When the keypad is not communicating with the controller and
the
Trip Relay NoComm is disabled, the unit will display the
following message and revert back to the date and time.
* PLEASE WAIT *
