# LCT - Explicit Threshold Rule

The Explicit Threshold Rule is an advanced configuration for the LCT device, similar to the standard Threshold Rule, but with the added capability to define both a minimum and a maximum threshold level. This rule triggers alarms when the measured parameter falls below the minimum or exceeds the maximum threshold, ensuring a more precise monitoring approach.

## Steps to Set Up the Explicit Threshold Rule for LCT:

1. **Select the Rule:**\
   Navigate to the **Rules** section of the LCT device dashboard and select the **Explicit Threshold Rule**.
2. **Toggle the Switch:**\
   Enable the rule by toggling the switch to the **ON** position.
3. **Enter a Name:**\
   Provide a meaningful name to identify the rule.
4. **Define Alarm Level:**\
   Select the alarm level—**Critical, Major, Minor, or Warning**—to categorize the severity of the alarm.
5. **Set the Parameters:**\
   Select the parameter to monitor from the available list (e.g., **temperature, battery level**).
6. **Define the Operator:**\
   Choose the operator (**Greater, Less, or Equal**) to specify the triggering condition for the rule.
7. **Set Threshold Levels:**
   * **Minimum Threshold:** Define the minimum value that will trigger the alarm if the parameter falls below it.
   * **Maximum Threshold:** Define the maximum value that will trigger the alarm if the parameter exceeds it.
8. **Define Notifications:**
   * Select **None** if no notifications are required (alarm will only trigger on the platform).
   * Select **Email** to send notifications and specify up to **five email recipients**.
9. **Save the Rule:**\
   Click **Save** to finalize and activate the 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-explicit-threshold-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.
