Access Control Service
Overview
The Access Control Service connects SBN to a WinPak access-control system so that card and door activity can be managed from SBN. On a fixed timer it collects the access-control work waiting in SBN — adding, changing or removing a cardholder and their card, setting access levels, PIN and expiry — and applies each change to WinPak. It also carries out door and point commands issued from SBN, such as locking, unlocking, momentarily releasing a door, or asking a device for its current status.
Traffic runs in both directions: as WinPak reports events and status changes, the service records them back into SBN so they are visible alongside everything else on the account. A separate communications check watches for a gap in that incoming traffic; if nothing is heard from WinPak within the configured window, the service can raise a communication failure message so the loss of contact is noticed. The service runs on a Windows machine with the WinPak components installed, and needs both a working SBN data-server connection and valid WinPak credentials — if either sign-in fails at start-up the service logs the reason and stops.

Only properties specific to this service are listed here. Common service properties (SBN Server connection, Logging, SMTP) are found <a href="/help/SBN-Services/Common-Properties">here</a>.
Timer (In seconds)
How often the service checks SBN for access-control work waiting to be sent to WinPak.
Comms — Timer (In seconds)
How long the service will go without hearing from WinPak before it treats the connection as failed. Incoming activity resets this window.
Send Comm. Fail Message
When checked, the service reports a communication failure once the window above has elapsed with no contact from WinPak. Leave it unchecked if you do not want these alerts.
Comm. Fail Message
The text reported when a communication failure is raised. Use wording that makes it clear to an operator which access-control system has lost contact.
Comm. Fail CID
The account the communication failure is reported against, so the alert appears on the correct installation.
