Horn Ring Feature
The Horn Ring feature allows the driver to enable and change the audible siren sound via the vehicle’s horn ring. Depend-
ing upon the position of Dip switches #6 & #7, the horn ring switch will emulate either the function of the “AIR” or “MANUAL”
button on the handheld controller or scroll through various siren tones. The Scrolling Feature is completely disabled when
Dip switch #6 is in the “on” position. When Dip switch #6 is in the “on” position, the horn ring will always emulate either the
“AIR” or “MANUAL” button as set by Dip switch #7.
The following outputs are achieved by tapping the horn ring:
Light Status Siren Status Output
OFF or Level 1 OFF Air Horn (or Manual) tone
Level 2 or Level 3 OFF Tapping scrolls through tones
OFF or Level 1 ON No change to tone.
Level 2 or Level 3 ON Tapping scrolls through tones
The following outputs are achieved by holding the horn ring:
Light Status Siren Status Output
ANY OFF Air Horn (or Manual) tone
OFF or Level 1 ON No change to tone.
Level 2 or Level 3 ON Air Horn (or Manual) tone
Footswitch/Pursuit Feature
A footswitch may be substituted for the Horn Ring feature.
Park Kill Feature
This feature deactivates the siren tones when the vehicle is either shifted into park or door is opened (depending on how the
end user wired this feature into the vehicle). The siren will remain deactivated until the vehicle is shifted into gear or the door
is closed and the siren is manually restarted. If Dip switch #4 is in the “on” position, Light Level 3 will also drop to Light Level
2 when the vehicle is shifted into park or door is opened. The lights will remain in Light Level 2 unless manually changed.

Operation
IMPORTANT WARNINGS TO USERS OF SIRENS: “Wail” and “Yelp” tones are in some cases (such
as the state of California) the only recognized siren tones for calling for the right of way. Ancillary
tones such as “Air Horn”, “Hi-Lo”, “Hyper Yelp”, and “Hyper Lo” in some cases do not provide as high
a sound pressure level. It is recommended that these tones be used in a secondary mode to alert
motorists to the presence of multiple emergency vehicles or to the momentary shift from the primary
tone as an indication of the imminent presence of any emergency vehicle.
