causes the effects described above to occur.

The " Scroll " mode is designed to allow the user to scroll through Wail, Yelp, HyperYelp and Airhorn tones by
utilizing the Remote input on the siren. This will usually be connected to the vehicle Horn Ring circuit. When the
three level lighting control switch is in postition 2 or 3, the Horn Ring transfer relay is energized. The user can
use the Horn Ring to sequence through Wail,Hyperyelp and Yelp by applying a quick, sharp tap on the horn.
Additional taps will scroll the siren to the next tone. Depressing the horn for longer periods will produce "
