# Acknowledgement-required and ongoing alarms

## Overview

### What are cleared alarms?

An alarm "goes" when the criteria for an alarm are no longer met and it is not an alarm that requires acknowledgment.

A cleared alarm no longer appears in the alarm overview. However, a cleared alarm always appears in the [↗ alarm history](/collection/english-v14/documentation/alarme-regeln-und-eskalationen/alarme.md#alarm-historie).

Alarms cannot be deleted from the alarm history.

### What are acknowledgment-required alarms?

Acknowledgment-required alarms appear in the [↗ alarm overview](/collection/english-v14/documentation/alarme-regeln-und-eskalationen/alarme.md#die-alarm-uebersicht), until they have been acknowledged by a user.

After an acknowledgment-required alarm has been acknowledged, the alarm is moved to the [↗ alarm history ](/collection/english-v14/documentation/alarme-regeln-und-eskalationen/alarme.md#alarm-historie)history.

Whether an alarm requires acknowledgment is configured in the [↗ rule](/collection/english-v14/documentation/alarme-regeln-und-eskalationen/regeln.md) configured by which the respective alarm is triggered. Acknowledgment-required alarms are highlighted by a marking **\[B]** highlighting.

{% hint style="info" %}
**Example 1**

A rule is created that triggers an alarm when the temperature drops below 20 degrees. The rule is set as *not acknowledgment-required* .

* The temperature drops below 20 degrees\
  ▷ An alarm is triggered\
  ▷ The alarm appears in the alarm overview
* The temperature rises back above 20 degrees\
  ▷ The alarm "goes"\
  ▷ The alarm no longer appears in the alarm overview ▷ The alarm appears in the alarm history

**Example 2**

A rule is created that triggers an alarm when the temperature drops below 20 degrees. The rule is set as *acknowledgment-required* .

* The temperature drops below 20 degrees\
  ▷ An alarm is triggered\
  ▷ The alarm appears in the alarm overview\
  ▷ The alarm is marked as acknowledgment-required **\[C]** tagged
* The temperature rises back above 20 degrees\
  ▷ The alarm "does not go"\
  ▷ The alarm remains visible in the alarm overview
* The alarm is acknowledged\
  ▷ The alarm no longer appears in the alarm overview\
  ▷ The alarm appears in the alarm history
  {% endhint %}

## 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://docs.buildings.ability.abb/collection/english-v14/documentation/alarme-regeln-und-eskalationen/alarme/quittierpflichtige-und-gehende-alarme.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.
