# LCT - Temperature Alarm Rule

The Temperature Alarm Rule for LCT devices monitors temperature readings and triggers an alert when they exceed or fall below predefined thresholds. This rule ensures timely notifications for temperature deviations, enabling prompt action to maintain operational efficiency and prevent damage.

## Steps to Set Up Temperature Alarm Rule for LCT:

1. **Access the Rule Page:**
   * Navigate to the device list, locate the desired LCT device, and open its dashboard.
   * Go to the **Rules** section, click on the **+** icon, and select the **Temperature Alarm Rule**.
2. **Activate the Rule:**
   * Toggle the switch at the top to enable the Temperature Alarm Rule.
3. **Set the Alarm Level:**
   * From the dropdown menu, select the alarm level:
     * Critical
     * Major
     * Minor
     * Warning
   * This helps prioritize and organize triggered alarms effectively.
4. **Define Temperature Thresholds:**
   * Use the slider to set the **minimum temperature**; the alarm will trigger if readings fall below this value.
   * Use the slider to set the **maximum temperature**; the alarm will trigger if readings exceed this value.
5. **Configure Notification:**
   * Choose **Email** to send alerts to up to five recipients, and insert their email addresses.
   * Select **None** to generate an alarm without sending notifications.
6. **Click Save:**
   * Save the configuration to apply the Temperature Alarm Rule.

## 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.g-iot.io/low-cost-tracker-full-device-guide-book/low-cost-tracker-greater-than-giots-functions/lct-rules/lct-temperature-alarm-rule.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.
