Wire Size and Termination - The wiring diagram on the previous page shows the
minimum wire size used for each connection, along with recommended lead color.
If the wire is longer than 10 ft. then use the next larger wire size. Use only high
quality crimp connectors. Make sure all connections are tight. Route wiring to
prevent wear, overheating and interference with air bag deployment. Use
grommets and sealant when passing through compartment walls. Minimize the
number of splices to reduce voltage drop. Ground connections should only be
made to substantial chassis components, preferably directly to the negative of the
vehicle battery. Install and check all wiring before connection to vehicle battery.
Wiring Connections:
BLACK LEAD: Connect to the negative of the battery, or to a good chassis
ground. Be sure to use minimum size #14 AWG wire.
RED LEAD: Connect to the positive side of the battery, or to a high current
power buss. A power relay may also be used. Be sure to use minimum size
#14 AWG wire.
YELLOW LEAD: Connect to +12VDC through a switched power supply
(possibly ignition). This will turn the siren on and off. Be sure to use
minimum size #18 AWG wire.
ORANGE LEAD: This lead supplies power for the backlighting of the siren.
Connect it to +12VDC from the dash lights, parking lights or other switched
source. Be sure to use minimum size #18 AWG wire.
BROWN LEADS: Connect one lead to each terminal or lead of the speaker. Be
sure to use minimum size #14 AWG wire.
Optional Connections:
BLUE LEADS: Used for radio repeat. Connect one blue lead to each terminal
of the radio speaker or output connector of the radio. Most radio outputs are
isolated, in which polarity would not be important. Radios with polarity
sensitive outputs should be connected w/ the blue wire from pin 6 to the
positive radio output, and the blue wire from pin 3 to the negative radio
output. Use #18 AWG wire.
GREEN LEAD: Used for remote Manual control. Connect to the horn ring
circuit or a remote switch. Circuit may be positive or negative with proper
jumper selection. See INSTALLER-SELECTABLE OPTION section (page
2) for jumper details.
NOTE: Cut lead short if not used & insulate w/ electrical tape.
GRAY LEAD: Used for Park Kill (Cut-off). Connect to dome light or added
door switch. Circuit may be positive or negative with proper jumper
selection. See INSTALLER-SELECTABLE OPTION section (page 2) for
jumper details.
NOTE: Be sure to cut lead short if not used and insulate with electrical tape.
Testing - Test all siren functions after installation to assure proper operation.
Test vehicle operation to assure no damage to vehicle.

OPERATION
GENERAL
This unit is designed for easy operation under the stress associated with high-speed
pursuit. Most siren functions are accessible with one simple motion without
repetitive activation of switches or automatic timed switching that can interfere with
desired operation.
SELECTOR SWITCH
Whenever +12VDC is applied to the yellow
wire, the ST160 will be "on". The rotary
selector switch controls the primary
operating function of the siren.
Thunder - Ultra-fast changing tone
used for maximum attention.
Yelp - A rapidly changing tone
used in congested areas.
Wail - A slower changing tone used on
highways.
HF (Hands Free) - Also known as Horn Ring Cycler, allows the user to cycle
through Wail, Yelp, Thunder and Manual by repeatedly pressing the
horn or other switch connected to the AUX input. Operating any
other switch resumes normal operation. Please note that this mode
disables the Manual push-button selection when a Wail, Yelp, or
Thunder tone is cycled to.
Manual - A silent mode that allows push-button Manual, push-button Horn,
and Public Address operation. The siren output winds down when
the Manual momentary rocker switch is released.
PA - A silent mode that allows push-button Manual, push-button Horn
and Public Address operation. The siren output terminates
immediately when the Manual momentary rocker switch is released.
Radio - Also known as Radio Repeat, this function amplifies a radio speaker
input for re-broadcast outside the vehicle.
functional, but no siren tones are available in this position.
