HC Accessibility Relay
OCB-8 relays can be configured as HC accessibility outputs for connections with electromechanical door
operators. When the OCB-8 relay has an HC accessibility assignment, the relay observes the following door
settings in the Client software as outlined:
 Aurora - the Extended Entry Timer setting for the door unlock time and the Extended Entry Door Held
Open setting for the door contact monitoring time
 System VII/Vantage - the Accessibility Door Timer setting for the door unlock time and the Accessibility
Door Held Open setting for the door contact monitoring time
Individuals with Extended Entry enabled (Aurora) or Accessibility Feature On (System VII/Vantage) in their
records trip the HC accessibility output relay when they present credentials for door access. The HC
accessibility relay option requires an additional OCB-8 purchased separately for CA4500B and CA8500B control
boards.
Ensure that the HC accessibility output relay matches the door output as indicated below.
