The external alarm port is an isolated switch output with the maximum current rating of 1.0 A and maximum voltage of 50V AC or DC.&#x20;

The switch is closed when there is no alarm and opens when alarm condition is detected.

The switch is connected to pins 1 and 2 of the XLR socket.

Note that there is an error in the incubator manual where the picture points to pins 1 and 2 but text tells to use pins 1 and 3. The text is incorrect and shall be corrected by the producer.

Solder two FK002 cables to pins 1 and 2 of the XLR female plug.

## B3 settings

In B3, FK002 sensor is used to observe the alarm status. Solder the FK002 cables to pins 1 and 2 of the XLR plug.

The alarm shall be raised when an opened state is detected.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.boomerang3.com/external-sensors-in-incubators/ivftech-freygen/alarm-port.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
