Howler Alarm

The Howler Alarm is a block from IC2 Nuclear Control. It is used to emit a loud siren noise when powered with a redstone signal. It is primarily used to warn users of overheating Nuclear Reactors. The Howler, unlike its counterpart, the Industrial Alarm, features the ability to select from 2 default sirens, along with other custom sounds that the user can add.

Recipe
As of version 2.2.0a, the recipe was modified slightly, as inspired by the GregTech recipe.

With GregTech recipes enabled, the recipe is modified to become more expensive.

Adding custom alarm sounds
To add new sound the player needs to unzip the mod file, copy the sound file (in alarm- .ogg format) to assets\nuclearcontrol\sounds\ folder and update the file sounds.json with a new line: "alarm- ": {"category": "master","sounds": [{"name": "alarm-***","stream": false}]},

Also the player will need to add this file to mod config file (config\IC2NuclearControl.cfg): S:allowedAlarms=default,sci-fi,***

The folder can then be zipped back into a jar file again or used as is.
