The Howler alarm is an item in the IC2 Nuclear Control Mod. When triggered by a redstone signal, it emits a sound that can be heard far away. It is commonly used in nuclear reactor setups to tell people when a reactor is overheating. There is an upgraded version of this item called the Industrial Alarm that has a longer range.
You can adjust the alarm range by scrolling the range indicator. It goes by powers of 2, for example: 2; 4; 8; 16; 32... up to 256 blocks.
