# Door status, history, and overrides

### **Viewing a door's status**

A door's 'Status' tab only displays when a reader is assigned to the door and the reader is online.

You can view a door's status to diagnose connection faults with the door. To view a door's status, open the door's properties and select the 'Status' tab. This tab displays the state of the door and all items assigned to the door. Status is updated in real-time.

### **Viewing a door's event history**

A door's 'Event History' tab only displays when a reader is assigned to the door and the reader is online.

You can view a door's event history to see a record of its historical events. For example, the event history will include a record of access denied events, access granted events, lock and unlock overrides, and other alarms such as 'forced' or 'open longer than expected'. You can filter the event history by 'All Events', 'Alarms', or 'Active Alarms', and by the time the event occurred.

### **Overriding a door**

After the configuration has been published and before the site is activated, you can unlock a door from within the SMB Installer Portal.

* **Opening the door**\
  The 'Open Door' override is intended to let someone through the door, and let the door lock again once they have passed through. Next to the door item, click **Open Door**. The door will unlock momentarily, then relock.
* **Unlocking the door**

  The ‘Unlock Door’ override is intended to unlock the door for a set period of time.

  1. Next to the door item, click **Unlock Door**.
  2. Set the **Duration in Minutes**. This duration is how long the door will remain unclocked for, before locking again. The default is 10 minutes.
  3. Click **OK**. The door will unlock for the set duration, then relock.

  To re-lock the door manually, select **Lock Door**. When the site is activated, the ‘Unlock Door’ override will be cancelled.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.security.gallagher.com/smb/site-configuration/configure-doors/door-status-history-and-overrides.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
