# Start-up alarm

**Start-up Alarm** To start all sequences that are associated with this hardware zone, you must press the release pushbutton for 3 seconds (default) and all gates of the zone must be closed. During this delay the start-up alarm is enabled when the button is pressed and can then be used to activate a siren. When the button is released the timer is reset and the ZONE RELEASE output is not activated.

   (*
   To start all sequences associated with this zone, the release pushbutton must be pressed, and all gates for the zone closed. 
   If a gate has been opened, the release pushbutton must be held in for five seconds before the ZONE RELEASE output is activated. 
   During this delay, if a gate had previously been opened and any associated sequences are ready to start, while the pushbutton is pressed the Start-up alarm is enabled, 
   this is then used to operate a siren. The Release pushbutton must be held in for the duration of the delay timer for the sequences associated with this zone to start. 
   If the pushbutton is released, the timer is reset and the ZONE RELEASE output will not be activated.

# Agent Instructions
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 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://infosys.selmotech.com/selmo-solution/selmo-solution-en/selmo-structure-and-standard/selmo-technical-standard-and-structure/description-selmo-plc-code/hardware-zone-control/less-than-hwzone_name-greater-than/less-than-hwzone_name-greater-than_control/start-up-alarm.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.
