Auxiliary Input
During installation an auxiliary input may be connected to the horn ring or other switching device. It provides the same
operation as pressing the Horn button or optionally the Man/Phsr button.
Cutout
During installation a cutout input may be connected to a door switch. It turns off any siren tone when the door is
opened. The siren tone will continue to be cut off even when the door is closed. Changing any siren control switch or
input will restore normal function.
Horn Ring Cycler (Optional)
During installation, the auxiliary input may be connected to the horn ring or other switching device, and the HRC option
programmed. With the mode switch set to the Standby position, the horn ring can be pressed repeatedly to select the
Wail, Yelp, Phaser and Standby tones or modes in succession. Operating any other switch resumes normal
operation. Please note that this option disables Phaser selection in the Wail or Yelp selector switch positions.
LIGHT SYSTEM CONTROLS
This unit provides large, durable switches for light control function. A 4-position lever switch provides control of
primary lighting functions. It also provides automatic activation of the siren system.
Setting the siren control switch to the On position can turn on backlighting of the light control switches.
Lever Switch
The lever switch provides additive control of lighting functions. Position 1 turns on a
single lighting function, such as lights pointing to the rear. Position 2 turns on an
additional light function, such as lights pointing to the front. Position 3 turns on an
additional 3rd lighting function, such as strobes. Position 3 also turns on a siren
function (see below). The installer determines actual function.
Automatic Siren
Position 3 of the lever switch provides automatic siren control. With both siren control rocker switches set at center
position (Stby/Off) the unit will activate the Wail siren tone. With the siren control switches set at Yelp/Off position 3
will activate the Yelp siren tone. The Man/Phsr and Horn switches will operate as if the siren control switches were set
at the corresponding positions. PA override is also functional. Automatic siren operation will not work if the right siren
control switch is set in the Rad position or the installer has disabled the function.
Rocker Switches
Four rocker switches are provided for various other lighting functions, such as alley lights, deck lights, headlight
flashers, etc. The switches light when turned on for night use.
