Issue
The Otis Destination Dispatch integration with Access Expert is not enforcing badge requirements for access to restricted floors. Users can select any elevator key without presenting a badge.
Product Line
EcoStruxure Access Expert
Environment
- Access Expert Hosted V3
- Mercury EP/LP4502 controller
- Otis Destination Dispatch elevator Compass System
Cause
The issue stems from missing routing table entries in the Mercury EP/LP4502 controller. These entries are essential for enabling communication between the Otis system and the Access Expert controller, which is required to enforce badge-based access restrictions.
Resolution
To resolve the badge enforcement issue:
- Verify Routing Table Entries on the LP/EP4502 controller’s web interface.
- Ensure the following entries are present:
- 192.168.50.0 – Enables communication with the Otis Compass Server.
- 192.168.1.0 – Enables communication with the Otis Destination Entry Computer.
Important: If either entry is missing, the systems will not communicate properly, and badge enforcement will fail.
- Refer to the Hardware Setup section in the integration guide for detailed instructions: Access Expert Otis Elevator Integration Guide
Detailed instructions for installing the Otis Destination Dispatch Access Expert Integration can be found in the Access Expert Otis Elevator Integration with Destination Dispatch Knowledge Base article.
