# Industrial Alarm

A siren for when the hull is pushed past what it can take. It stays quiet as long as you are within the limit.

## Recipe

![Industrial Alarm recipe](https://1371052705-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FV22FKtcNjWW37kUFLLdR%2Fuploads%2Fgit-blob-9d6c58e9607f65fa9f2798af73d34a9afbe4b052%2Findustrial_alarm.png?alt=media)

## How it works

Place it on the submarine. Once the submarine goes deeper than its weakest hull block allows, the alarm flashes red and sounds. Every 5 m further down it goes faster, until the hull gives way.

## Settings

Right-click it to open its screen:

* **Alarm sound:** the default siren, or your own sound (see below).
* **Sounding:** how long it sounds and lights up each time. Match it to the length of your sound.
* **Pause:** the silence between two alarms.
* **Volume.**
* **Faster in danger:** speeds the alarm up the deeper the hull is past its limit.

### Custom sounds

Drop `.ogg` files into `config/create_submarine/alarms`, the button on the screen opens that folder. They show up in the sound list. On a server, the files must be in the server's own folder.

## Photosensitivity

The alarm flashes up to five times per second. If you are photosensitive or epileptic:

* the client option `photosensitiveMode` turns off its coloured flashing light,
* the server option `alarmSteadyLight` keeps the lamp on steady instead of flashing, for every player.

The game asks about this the first time you launch it.

## Good to know

* The coloured moving light comes from the [Vortex Engine](/create-deep-seas-wiki/getting-started/graphics.md). Under an Iris shader pack, the alarm uses normal Minecraft light.
* It holds down to 350 m.

**Details to look for**

* By default it speeds up in stages every 5 m past the limit: one flash every 2 seconds, then 1.5 s, 1 s, 0.5 s, and 0.2 s from 20 m past the limit and during the implosion.
* With the Vortex Engine, its red light really lights up the room around it, and it moves.
