# Alarm delivery

The Boomerang system may deliver information about an alarm event to a user by email, SMS or voice call or a combination of these methods. 

There is also a dedicated Android app that can be used to observe the system status.

Boomerang can also signal an alarm activating a strobe light or another type of alarming equipment. 

A module called B3 Web Panel (P/N WPAN-CTRLR) can display the summary of the measuring points' status on a monitor.

The way the alarms are delivered is defined by the system administrator using alarm groups.

## 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.boomerang3.com/boomerang-3-domain-administrator-manual/dashboard/alarms_and_warnings/alarm-delivery.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.
