Cause

The AN 248 Security Expert - Configuring Basic Elevator Control - Integration Guide does not describe how to handle credential types as the Authentication mode when configuring Elevator cars.

For card formats other than the default selection in the Door record, Credential Types are used with Door Types to define the credential to be used to authenticate at that door. When configuring Elevator control however, the Elevator car record does not have a Door Type field to set the relevant Credential Type to use.

Resolution

1. In the Elevator Car record set the Authentication mode field to "<not set>". This will process as normal if the user has a valid credential based on the Reader Expander Reader Port configuration.
2. The Reader Expander Port is set to "Custom Credential" and "Elevator" for access.
3. The Elevator car reader will go through the list of Credential Types programmed in the controller and match the Bit Stream of the card read to the first Credential Type that fits.
   1. If there were three Credential Types programmed as below;
      1. 32 Bit
      2. 37 Bit
      3. 26 Bit
   2. Badging a 26 bit card would use the first 26 bit format found in the list which would be Credential Type number three.
4. Typically this would work fine in most cases however some additional allowances will need to be made if there are multiple credentials with the same number of bits.
   1. If there were multiple 32 bit formats;
      1. ESMI 32 Bit
      2. Custom 32 Bit For Elevators
   2. The system will use the first matching format which would be the ESMI 32 bit, this would result in your elevator processing the wrong format and therefore potentially not granting access.
   3. To resolve this the Credential Types would need to be programmed so that the first credential is the one the elevator needs to use.
