Interfloor Matrix for Connected State
Defines which floors don't require a credential (public floors) and which floors require a credential and access (secure floors). Applies to the state when the security system is connected to the elevator system and is functioning normally.
Interfloor Matrix for Disconnected State
Defines which floors are public and which floors are not accessible when the security system is disconnected from the elevator system.
PIN Entry
DDE kiosk keypad allows a PIN (Personal Identification Number) to be entered instead of a card credential for identification and access.
Global Keypad
A keypad which can dispatch any elevator to any user in any bank.
Turnstile Elevator Call
The credential used at a turnstile is also sent to the DDE system and requests to dispatch an elevator for this passenger to their default floor.
User Select Floor
After a credential is used the person is presented with the list of floors for which they have access and they can select one.
Default Floor
After a credential is used the person's default floor is used to dispatch an elevator.
Default Floor Override
After a credential is used the person can do nothing and go to their default floor or select any other accessible floor.
BluREMOTE
A person can use BluREMOTE on their smartphone to request an elevator to any of their accessible floors. The DDE system sends the elevator assignment back to BluREMOTE on the person's smartphone.
Person Reader Integration
The Person Reader is an all-in-one intelligent reader that can display real time destination dispatch car assignments on turnstiles and can be used as a built-in or external readers to DDE kiosk/display terminals on each floor.
Reader Connected to DDE System
The credential reader is connected to the DDE system and sends credential data to the security system for lookup and authorization. The security system sends the list of allowed floors back to the elevator system for display to the person on the DDE keypad. After the person selects a floor, the DDE system assigns, dispatches and displays the dispatched elevator on the DDE keypad. Floor selection and elevator assignment information is sent back to the security system for auditing and reporting.
Reader Connected to the Security System
The credential reader is connected to the security system and based upon the valid read of a credential sends the list of allowed floors to the DDE system for display to the person on the DDE keypad. After the person selects a floor, the DDE system assigns, dispatches and displays the dispatched elevator on the DDE keypad. Floor selection and elevator assignment information is sent back to the security system for auditing and reporting.
Failover Functionality
The DDE system has two controllers. One in working mode and another in standby mode. If one of the controllers fails the other one becomes the working controller. At that point the security system switches to the new working controller and continues normal operation.
Audit Reporting
The DDE system reports what floor the person selected and which elevator car was assigned to the security system for auditing and reporting purposes.
Traffic Segmentation
The DDE system can divide the elevator bank into several segments. Each person can be assigned a specific segment. This ensures that people from competing organizations don't ride in the same elevator cars.
Automatic Reconnection
After security system or elevator system is broke, shut down or disconnected there is an established process of full automatic restoration of normal functionality without human intervention.
Heartbeat
The DDE and security systems exchange small messages (heartbeats) to tell the other system that it is functioning normally. This is very important for system health monitoring.
Version Negotiation
Security system manufacturer and Elevator system manufacturer keep updating their software. Version negotiation support allows both systems to find the protocol version that both of them can support.
ADA
Security System sets an ADA flag in the message it sends to the elevator system after the handicapped cardholder swipes the card. The elevator system dispatches an appropriate car (suitable for a wheel chair), annunciates by voice the dispatched car name (number) and waits for this passenger longer than for a regular passenger.
VIP
Security System sets a VIP Flag in the message it sends to the elevator system. Elevator system dispatches a separate car for the VIP cardholder.
Vertigo
Similar to the ADA support. A special car is dispatched.
Split Group Operation
Security system sets a split group operation flag in the message it sends to the elevator system. Elevator system dispatches only specific cars to this cardholder.
Fire Warden
Similar to VIP support, but this request overrides any other dispatch requests that are already queued in the elevator system.
Configurable User Flags
Spare flags that can be set for certain functionality specific for a particular building.
Code Blue
Security system sends a message to the elevator system that puts the elevator system into a special mode (usually when there is a terrorist act, robbery or any other police activity).
Service Operations
Special flags that put the elevator system into any state needed for service. Very specific to the particular building needs.
Security Database
The DDE system maintains its own person/credential database. Credential lookup and authorization happens in the elevator system. Security system only adds and removes the cardholders from the elevator system database.
