# Managing multiple sites
Gallagher’s Multi-Site feature gives customers the ability to manage and interact with the security systems of multiple physically-separate sites through the one SMB app.
This is ideal for businesses where user and alarm management are centralised or staff have a need to move between sites. It can be equally beneficial for those wanting to manage the security systems both at their business premises and at home.
Switching between sites is easy within the SMB app, and site managers will receive live notifications if an incident occurs at any of their sites.
A user’s email address is the common piece of information that allows them to be linked to multiple systems.
***
### Switching between sites
To switch between sites:
1. Within the SMB app, select the more options menu (three vertical dots) in the top right-hand corner.
2. Select **Switch Site**.
1. The sites that the user has the privilege to see are displayed.
3. Click on the site you want to switch to.
***
### Managing Users
From the **Team** page on any site, a Site Manager can add, disable, and delete access for users across all sites for which they are a Site Manager. They don’t need to switch between sites to manage users.
For more information, refer to [Managing Users](/smb/smb-app/team/managing-users.md).

### Managing alarm incidents and system alarms
When an alarm incident or system alarm occurs for a site that you are a Site Manager for, you receive a notification. By clicking on the notification, you are taken to the site that the notification was from.
The Site Manager can have selected any site within the SMB app and still receive notifications from all sites.

## 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/smb-app/site/managing-multiple-sites.md?ask=&goal=
```
`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.
