Horn Ring Feature
The Horn Ring feature allows the driver to enable and change the audible siren sound via the vehicle’s horn ring. Depending 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:

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 manu-
ally 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.
WARNING!
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.
EU Lock Feature
By setting either Dip switch #8 or Dip switch #9 to the “on” position, the EU Lock Feature is enabled. This feature ensures that at least a certain
Light Level is on while any siren tones, except Air Horn, are on. If the siren is turned on without the minimum Light Level on, then that Light
Level will turn on. If later that Light Level is turned off, then the siren will also turn off if it is still on. The minimum Light Level is set by the fol-
lowing table:
For Example: If EU Lock Level 1 is enabled (by setting Dip switch #8 “ON”, and Dip switch #9 “OFF), then at least Light Level 1 will
always be on while the siren is on. If the siren is turned on and no lights are on, then Light Level 1 will also turn on. When Light Level
1 is turned off, then the siren will also turn off if it is still on.
