Decide when you want to activate a sound with the Automatic Trigger. It plays the sound automatically, but has three built-in options for sound activation. One repeats the sound, another will play the sound at random, and the third controls the frequency of when the sound activates automatically.
The Automatic Trigger also has lights that tell you which option is active and a stop button to turn off the sound.
