Horn Ring

(Controls, Radio VIPs)

This feature is used by the Siren option to monitor the state of the vehicle’s Horn Ring, typically through a relay controlled by the Horn Ring Transfer VIP Output (alternately, a momentary-contact pushbutton switch may be installed, in a location convenient to the driver).

	While broadcasting a Siren tone (activated with a radio-user initiated Siren button-press), the selected Siren tone is changed by pressing the vehicle’s Horn-Ring.
	During Manual Siren Tone operation (activated with a radio-user initiated Manual button-press), the selected Manual Tone sounds when the vehicle's Horn Ring is pressed, and ends when the Horn Ring is released.
