Sirens are an integral part of an effective audio/visual emergency warning system. However, sirens are only short range
secondary warning devices. The use of a siren does not insure that all drivers can or will observe or react to an emergency
warning signal, particularly at long distances or when either vehicle is traveling at a high rate of speed. Sirens should only be
used in a combination with effective warning lights and never relied upon as a sole warning signal. Never take the right of way
for granted. It is your responsibility to be sure you can proceed safely before entering an intersection driving against trafc, or
responding at a high rate of speed.
The effectiveness of this warning device is highly dependent upon correct mounting and wiring. Read and follow the manu-
facturer’s instructions before installing this device. The vehicle operator should check the equipment daily to insure that all
features of the device operate correctly.
To be effective, sirens must produce high sound levels that potentially can inict hearing damage. Installers should be warned
to wear hearing protection, clear bystanders from the area and not to operate the siren indoors during testing. Vehicle operators
and occupants should assess their exposure to siren noise and determine what steps, such as consultation with professionals
or use of hearing protection should be implemented to protect their hearing.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to understand and obey all laws
regarding emergency warning devices. The user should check all applicable city, state and federal laws and regulations. Code
3, Inc., assumes no liability for any loss resulting from the use of this warning device.
Proper installation is vital to the performance of the siren and the safe operation of the emergency vehicle. It is important to
recognize that the operator of the emergency vehicle is under psychological and physiological stress caused by the emergency
situation. The siren system should be installed in such a manner as to: A) Not reduce the acoustical performance of the system,
B) Limit as much as practical the noise level in the passenger compartment of the vehicle, C) Place the controls within convenient
reach of the operator so that he can operate the system without losing eye contact with the roadway.
Emergency warning devices often require high electrical voltages and/or currents. Properly protect and use caution around live
electrical connections. Grounding or shorting of electrical connections can cause high current arcing, which can cause personal
injury and/or severe vehicle damage, including re.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING
DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.
WARNING
Standard Features
The Siren consists of a remotely mounted siren amplier with integral lighting control. This is operated by a compact control panel designed to be
conveniently mounted near the operator. This model includes the following standard features:
- Primary Push-Buttons: WAIL, YELP, ALT TONE (Default Tone for ALT TONE is Hi-Lo 1 but can be congured to use other tones)
- Secondary Tones: Multiple User Congurable Tones
- MANUAL Push-Button: Default tone is the Manual Wail.
- AIR HORN Push-Button: Multiple User Congurable Tones.
- 8 Auxiliary Controls: Default to control Auxiliary A through Auxiliary H outputs. Can be congured to control multiple Auxiliary outputs from one
Auxiliary push-button.
- ArrowStik Control: Muliple User Congurable Flash Patterns (For use with conventional ArrowStik).
- Integrated Centrally Controlled ArrowStik
- Integrated Code 3 Serial Lightbar Control
Introduction
The Siren is a new remote control electronic siren that has been designed to meet the needs of all emergency vehicles. The Siren incorpo-
rates many of the popular features of the past and uses microprocessor based circuitry and MOSFET technology. All standard features are available
along with many new features that are not available on any other Code 3 siren: Fully Congurable 3-Level Switch, Selectable Tones, Adjustable
Backlighting and much more.
!
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.
WARNING

The following features are standard in the Siren (tones
and sequences may differ with user selectable congura-
tion):
Control Head Congurable (In Vehicle)
Adjustable Backlighting - Backlighting is independent of
siren status. The dimming of the lit push-buttons can be
adjusted as desired. Press and hold either the LEFT or
RIGHT push-buttons for one second. This puts the Control
Head into an adjustment mode for the backlighting. Re-
peatedly press or hold the RIGHT push-button to increase
the brightness or the LEFT push-button to decrease the
brightness. The brightness can be decreased down to
include an off condition. Press the DIM push-button to exit
from this adjustment mode.
Microphone Volume Adjustment - Press and hold the
PTT push-button on the microphone. Then press and hold
the Left or Right push-button for one second to enter the
volume adjustment mode. Then press the Left or Right
arrow push-buttons to decrease or increase the volume,
respectively. Once it’s adjusted to the desired volume,
press the DIM push-button or release the PTT push-
button to save the setting.
Radio Rebroadcast (RRB) - Broadcast two-way radio reception over siren speakers. These inputs are transformer coupled to prevent loading of the
radio. The audio from the 2-way radio is rebroadcast over the siren speakers. The siren tones do not operate when this is activated. All other control
functions operate normally. To connect in the signal to be broadcast, simply tie the two signal lines to the RRB1 and RRB2 inputs of the Amplier
(polarity is not an issue). The default setting of the Siren has this option turned off. See the Software User Manual for conguring one of the
Auxiliary push-buttons for activating this feature. Once congured to an Auxiliary push-button and that push button is activated, only then can the
volume be adjusted by holding down the RIGHT or LEFT push-button for one second. Then pressing the RIGHT or LEFT push-button increases or
decreases the volume. Pressing the DIM push-button will save the settings. There is also a time-out but will save the settings before exiting as well.
The RRB feature will automatically shutoff to protect from overheating of the Siren.
Computer Congurable
WAIL Push-Button - This push-button produces the Wail tone when pressed. By default, it also turns on the Level 3 lights but this is congurable
to Level 2, Level 1, or no lights. The override tone is also congurable for this feature. Pressing the push-button a second time turns this feature off.
Operation of this feature is affected by SirenLock, 3-Level Switch, and Park Kill features. See these sections for details.
YELP Push-Button - This push-button produces the Yelp tone when pressed. By default, it also turns on the Level 3 lights but this is congurable
to Level 2, Level 1, or no lights. The override tone is also congurable for this feature. Pressing the push-button a second time turns this feature off.
Operation of this feature is affected by SirenLock, 3-Level Switch, and Park Kill features. See these sections for details.
ALT TONE Push-Button - Both the primary and override tones are congurable for this push-button. This push-button produces the Hi-Lo 1 tone
when pressed. It also turns on the Level 3 lights but this is congurable to Level 2, Level 1, or no lights. The override tone is the Hyper-Lo 1 tone.
Pressing the push-button a second time turns this feature off. This push-button can be disabled in the conguration software. Operation of this fea-
ture is affected by SirenLock, 3-Level Switch, and Park Kill features. See these sections for details.
MANUAL Push-Button - In its default conguration, this push-button generates the Manual Wail tone. When pressed, the Manual Wail tone will
ramp up to its highest tone and hold. It will hold as long as the MANUAL push-button is held. When the MANUAL push-button is released, the tone
will ramp down and return to the previous function. The conguration software can change this to be in Hit-N-Go mode, Scroll mode, or Wail Stop
mode. This can also be congured to react differently based on Siren status. Operation of this feature is affected by SirenLock, 3-Level Switch, and
Park Kill features. See these sections for details.
AIR HORN Push-Button - In its default conguration, the AIR HORN push-button produces the Air Horn 1 tone as long as it is pressed. It will over-
ride all other siren tones. The conguration software can set this tone to Air Horn 1 or Air Horn 2. The AIR HORN push-button will work with Park Kill
and SirenLock but can be congured to be disabled. See the Siren Conguration Software User Manual for conguration details.

Auxiliary A-H Push-Buttons - As congured by the Siren Conguration Software, eight on/off Auxiliary push-buttons are readily accessible for
controlling the Auxiliary outputs of the Amplier. Each Auxiliary push-button can be custom labeled with the supplied label kit. Each push-button is
backlighted when activated to alert the operator. The default setting is for each Auxiliary push-button to control the corresponding Auxiliary output of
the Amplier. Auxiliary A through F supplies power to the load through the connector pins labeled A thru F. Auxiliary G and H supplies power with a
positive or ground voltage to the load through the connector pins labeled G and H.
3-Level Switch - The Control Head provides a 3-Level switch for changing the emergency warning mode. The 3-Level switch is located in the top left
corner of the control head. When the 3-Level switch is switched to the far left position, the unit is off. When the 3-Level switch is in the rst position
from the left, the level 1 conguration of the lights is turned on. When the 3-Level switch is in the second position from the left, the level 1 & 2 con-
guration of lights are turned on. When the 3-Level switch is in the third position from the left, the level 1, 2, & 3 conguration of the lights are turned
on. Level 1, 2, & 3 activate the LightAlert if supplied. These default settings can be altered using the Siren Conguration Software. The 3-Level
switch may be overridden by other push-buttons. If the push-buttons are programmed to a higher level than the position of the 3-Level switch, the
push-buttons will take precedence. If the push-buttons are programmed to a lower level than the position of the 3-Level switch, the 3-Level switch will
take precedence. The lighting can be set to various levels for the WAIL, YELP, ALT TONE, MANUAL, and AUX push-buttons. Visit these sections in
the conguration software to set these preferences.
3-Color Status LED - Three LEDs are visible on the front of the remote siren amplier. When the 3-Level switch is set to Level 1 the green LED
lights. When the siren is set to Level 2 both the green and yellow LEDs light. When the siren is set to Level 3 the green, yellow, and red LEDs light.
These LEDs indicate the level of the siren and controls. These Levels are congurable in the Siren Conguration Software User Manual.
Hands-Free - Hands-Free mode is directly linked to the Auxiliary push-buttons. By default, the Hands-Free mode is disabled. When an Auxiliary
push-button is congured for Hands-Free and that Auxiliary push-button has been turned on, the Hands-Free mode is active but waiting for an initial
press of the horn ring to activate the WAIL push-button. A second press of the horn ring will activate the YELP push-button. Pressing the horn ring a
third time will activate the ALT TONE push-button. A fourth press of the horn ring will return to the WAIL push-button. This type of scrolling will con-
tinue until the user deactivates the Hands-Free Scroll. Pressing the Auxiliary push-button turns off the sound and deactivates the Hands-Free Scroll.
Pressing and holding the horn ring will turn off the sound but leave Hands-Free Scroll in the active mode. The Remote input and Manual push-button
can also be congured for multiple functions during Hands-Free mode. Please refer to Z3 Siren Conguration Manual for details. See Table on page
6 for factory settings.
Horn Ring - The siren accepts either a positive or a ground signal into the Horn Ring input on the Amplier. The Horn Ring signal is disconnected
from the vehicle and connected to the Horn Ring input of the Amplier. The Horn Relay wire is then run from the Amplier to the horn of the vehicle.
This allows the Horn Ring to execute some of the user selectable functions of the Siren. The Horn Ring can be congured to multiple functions in
the Siren Active and Siren Inactive modes of operation. The Horn Ring is set to Scroll in the Hands-Free mode and cannot be changed. Please see
the Siren Conguration Software User’s Manual for details.
Horn Ring Transfer - The Horn Ring Transfer allows the Horn Ring to be disabled from the vehicle horn and the controls transferred to control other
siren tones. The Horn Ring Transfer can be set to occur at Level 1, Level 2, Level 3, or any combination of the three.
Remote - The siren accepts either a positive or a ground signal into the Remote Input wire on the Amplier. This Remote Input wire is usually con-
nected to a user supplied switch. The siren is factory set for a ground signal. The Remote input can be congured to multiple functions in the Siren
Active, Siren Inactive, and Hands-Free modes of operation. Please refer to the Siren Conguration Software User’s Manual for details. See Table
on page 6 for factory settings.
Hit-N-Go - Hit-N-Go only works when a siren tone is active. Once a siren tone is active, Hit-N-Go is activated simply by pressing the Horn Ring
(Vehicle Horn Control) or pressing the Remote input. It will go to the Override tone for 8 seconds and then return to the primary tone. The actual tone
for the Hit-N-Go depends on which push-button is active. If the WAIL push-button is active then the Hit-N-Go (Override) tone is the Yelp tone. If the
YELP push-button is active then the Hit-N-Go tone is the Hyper-Yelp 1 tone, and if the ALT TONE push-button is active then the Hit-N-Go tone is the
Hyper-Lo 1 tone. These Override tones are user congurable in the Conguration Software. The siren can also be congured so the MANUAL push-
button is Hit-N-Go activator.
Scroll - Scroll only works when a siren tone is active. Once a siren tone is active, Scroll is activated simply by pressing the Horn Ring (Vehicle Horn
Control) or pressing the Remote input. The Scroll Mode will cause the siren to cycle through the WAIL, YELP and ALT TONE push-buttons. For
example, if the WAIL push-button is active and the Horn Ring (congured to scroll) is pressed, the YELP push-button will become active. Another
press of the Horn Ring will activate the ALT TONE push-button. Another press of the Horn Ring will return to activate the original WAIL push-button.
The siren can also be congured so the MANUAL push-button activates the Scroll. NOTE: Pressing and holding the Horn Ring for more than a half
second will cause the Siren to generate the Air Horn tone.
Scroll On/Off - The Scroll On/Off mode works like the Scroll mode except the Siren will scroll the primary tones through an off state. The Siren
will scroll from Wail to Yelp to Alt Tone to off and then back to Wail. The Remote input can be congured to activate Scroll On/Off. NOTE: Pressing

5
and holding the Horn Ring for more than a half second will cause the Siren to generate the Air Horn tone.
Load Management - The Load Manager allows setup of three Dropout Voltage Groups by selecting which output to drop out when the vehicle power
levels fall below the specied voltage for that group. The default is for no groups to drop out for any reason. See the Siren Conguration Software
User Manual for conguration details.
LoadMGRTM - This output can control the power supplied to other loads in the vehicle. The power to these loads can be turned off when the driver
turns off the vehicle or the voltage of the battery for the vehicle has dropped below a predetermined voltage level. If the Sleep Mode timer is set to a
value other than instant, the LoadMGR will turn off after the Sleep Mode timer has expired (see the denition of Sleep Mode). This output is current
limited to 1 amp continuous. Connecting the LoadMGR output to an external relay will allow larger external loads to be controlled. The InterClear®
wire is used for the LoadMGRTM function. InterClear®and LoadMGRTM cannot function simultaneously.
Park Kill - By default, Park Kill puts the siren tones in standby and drops out the Level 3 lighting. Park Kill occurs when the vehicle is shifted into
park. Once Park Kill is activated, the siren tones are in standby. The siren tones will remain in standby until the vehicle is shifted into drive and an
action occurs such as pressing one of the Control Head push-buttons, changing the position of the 3-Level Switch, or keying the microphone. There
are multiple options that can be congured in the conguration software.
The Level 3A and siren tones are in standby during Park Kill, and the Auxiliary buttons are not affected by the Park Kill function by default. See the
Siren Conguration Software manual for details. The default for the polarity of the Park Kill input is ground (congurable to positive voltage). If the
Park Kill input is switched to ground by shifting into park, it will activate the Park Kill functions.
InterClear®- Connect to the device or circuit that is to be activated by the InterClear®feature. The InterClear®circuit supplies power to the Inter-
Clear®wire, and it is internally current limited at 1 Amp. Power is supplied to the InterClear®wire when Hit-N-Go is activated. Power is also supplied
to this wire when the Manual Wail or Wail Stop functions are activated.
EU Lock - This function is to meet the requirements of some European Union countries to verify that the Warning Lights for the emergency vehicle
are actually operational before allowing the siren to generate tones. This is normally congured to be disabled in the Siren Conguration Soft-
ware. It can be enabled during conguration of the siren. This feature requires user provided current sense module for the lights.
SirenLock - By default, the SirenLock feature is disabled. With SirenLock disabled, the Siren will be in a “Siren Active” mode of operation, and
this will disable the “Siren Inactive Function” for the Horn Ring input, Remote input, and Manual push-button. In the Siren Conguration Software,
the SirenLock can be changed to allow siren tones when in Level 1, Level 2, and/or in Level 3. Air Horn, Radio Rebroadcast, Manual, and Public
Address are unaffected by this feature.
LightAlert - By default, the LightAlert feature will produce an audible “beep” on a periodic basis if any lighting is activated including Auxiliary and Ar-
rowStik push-buttons. This is intended to alert the operator that lights are on. The Siren Conguration Software allows this feature to be disabled
for selected functions.
Sleep Mode - This is by default set to instantly turn off the Siren system when the vehicle ignition is turned off. This can also be set in the congu-
ration software to turn off after 10, 20, or 30 minutes.
Not Congurable
Alarm - This is an input that senses a +12VDC signal even when ignition is turned off. Connect the wire labeled ALARM to a circuit that can supply
a +12VDC signal when activated. When a +12VDC signal is seen on this input, a repetitive alarm will sound on the output speakers continuously
until the +12VDC signal is removed. For example, this can be used to alarm the police ofcer when a temperature sensor on a K-9 unit has reached
dangerous levels. The alarm will continue until the temperature sensor has returned to safe levels.
Automatic Short Circuit Protection - The siren will sense a short circuit on the speaker terminals and automatically go to standby until the fault is
removed. Once the fault is removed, the siren will return to normal operation.
Instant-On - There is no “ON/OFF” switch. Selecting any siren function, or keying the microphone will activate the selected siren function, assuming
the siren is properly installed and the vehicle’s ignition is switched on.
Microphone - Pressing the push-button on the microphone will automatically override the current mode of the siren tones and switches to public
address mode. Push-To-Talk (PTT) is highest priority and overrides all other siren tones. The microphone is easily plugged into the Control Head with
a modular phone plug. This allows the microphone to be unplugged for service or replacement.
“Stuck Mic” - When the PTT push-button is pressed, the siren will disable the PTT after 30 seconds of being held. The siren will return to its previ-
ous condition even though the push-button is still being held in the on position. This will avoid the situation where the PTT push-button is “stuck” in
the on position for extended periods. To continue using the PTT simply release the PTT push-button and press it again.

Unpacking &
Pre-installation
After unpacking your Siren, carefully inspect the
unit and associated parts for any damage that may
have been caused in transit. Report any damage to
the carrier immediately.
Verify all components have been delivered. The box
should contain the Siren Control Head, Ampli-
er, cable/harness bag, microphone, hardware bag,
legend set and user manuals bag.
Installation &
Mounting
The Siren Control Head is made to mount
directly in the console of most leading manufactur-
ers as seen in Fig. 3 shown below. It may also be
!
All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements
of sufcient strength to withstand the forces applied to the device. Ease of operation and convenience to the operator should
be the prime consideration when mounting the siren and controls. Adjust the mounting angle to allow maximum operator vis-
ibility. Do not mount the Control Head Module in a location that will obstruct the drivers view. Mount the microphone clip in a
convenient location to allow the operator easy access. Devices should be mounted only in locations that conform to their SAE
identication code as described in SAE Standard J1849. For example, electronics designed for interior mounting should not be
placed underhood, etc. Controls should be placed within convenient reach* of the driver or if intended for two person operation
the driver and/or passenger. In some vehicles, multiple control switches and/or using methods such as “horn ring transfer” which
utilizes the vehicle horn switch to toggle between siren tones may be necessary for convenient operation from two positions.
*Convenient reach is dened as the ability of the operator of the siren system to manipulate the controls from their normal driv-
ing/riding position without excessive movement away from the seat back or loss of eye contact with the roadway.
WARNING
mounted above the dash, below the dash or on the transmission tunnel using
the mounting hardware supplied (see Fig. 2 above). Also reference page 15
and 16 for description of components and Code 3 part numbers. Ease of
operation and convenience to the operator should be the prime consideration
when mounting the siren and controls. When choosing a mounting location
the user must consider the deployment area for the air bag of the vehicle and
other factors which might impact the safety of the vehicle occupants.
NOTE: Setups and adjustments will be made in steps that may require ac-
cess to the rear area of the unit. Plan the installation and wiring accordingly.

Amplier Connections
All Amplier connections are made on one side of the Amplier as seen in gure 4. See wiring diagram on page 13. All Amplier connections are
quick disconnect requiring no tools.
!
Larger wires and tight connections will provide longer service life for components. For high current wires it is highly recom-
mended that terminal blocks or soldered connections be used with shrink tubing to protect the connections. Do not use
insulation displacement connectors (e.g. 3M® Scotchlock type connectors). Route wiring using grommets and sealant when
passing through compartment walls. Minimize the number of splices to reduce voltage drop. High ambient temperatures (e.g.
under-hood) will signicantly reduce the current carrying capacity of wires, fuses, and circuit breakers. Use “SXL” type wire
in engine compartment. All wiring should conform to the minimum wire size and other recommendations of the manufacturer
and be protected from moving parts and hot surfaces. Looms, grommets, cable ties, and similar installation hardware should
be used to anchor and protect all wiring.
Particular attention should be paid to the location and method of making electrical connections and splices to protect these
points from corrosion and loss of conductivity. Ground terminations should only be made to substantial chassis components,
preferably directly to the vehicle battery.
The user should install a fuse sized to approximately 125% of the maximum Amp capacity in the supply line and each switched
circuit to protect against short circuits. For example, a 30 Amp fuse should carry a maximum of 24 Amps. DO NOT USE 1/4”
DIAMETER GLASS FUSES AS THEY ARE NOT SUITABLE FOR CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit
breakers are very sensitive to high temperatures and will “false trip” when mounted in hot environments or operated close to
their capacity. Fuses or circuit breakers should be located as close to the power takeoff points as possible and properly sized
to protect the wiring and devices.

Amplier Power Distribution
The Level 1, 2, 3A and 3B outputs can supply a maximum of 15 Amps each or a combined total of 50 Amps. Each Level has a 20 Amp fuse installed
inside the Amplier. Fuses may be accessed through the panel on top of the Amplier.
The Auxiliary outputs A, B, C and D can supply a maximum of 5 amps each. Auxiliary outputs E, F, G and H can supply a maximum of 10 amps each.
The combined total for all Auxiliary outputs is 50 Amps. Auxiliary outputs A, B, C and D have 7.5 amp fuses and Auxiliary outputs E, F, G and H have
15 amp fuses. Fuses may be accessed through the panel on top of the Amplier.
Control Head Connections
The connection from the Control Head to the remote Amplier is made using a standard CAT-5 cable (P/N T56649) connected to the port labeled
SIREN AMP on the back of the Control Head. This cable is found in the Harness & Cable Bag P/N T56641. See gure 5 below.
In addition, the microphone P/N T11856 connects to the Control Head port labeled PA MIC. The microphone also uses a Microphone Hanger Bracket
(P/N T00631) that mounts to the dash of the vehicle.

Conventional ArrowStik Connections
CC ArrowStik Connection
The Siren can connect directly to any Code 3 Centrally Controlled (CC) Lightbar ArrowStik and some non-Code3 CC Lightbar ArrowStiks using
Code 3 harness P/N T56629 (see gure 8). This harness is found in the Harness & Cable Bag P/N T56641. Refer to the wiring diagram on page 13.
Conventional ArrowStik Connection
The Siren can also connect directly to a conventional ArrowStik or both at the same time using Code 3 harness P/N T56631 (see gures 6 & 7).
Refer to the wiring diagram on page 13. If a conventional ArrowStik is desired see the Siren Conguration Software Manual for details regarding
ash pattern selection.
The 9 wire harness can be connected to drive an 8, 6, or 5 head ArrowStik. The Siren is compatible with some non-Code 3 ArrowStik products.
The Siren conventional ArrowStik outputs provide a current sink (ground) signal when active. Each output is rated for an absolute maximum of 5
amps. See the wiring diagram on page 13 and the install manual for your ArrowStik product for wiring details.
8 HEAD HARNESS CONNECTIONS
When viewing the vehicle from the rear, the ArrowStik harness is connected in the following order from Driver side to Passenger side: Blue, Yellow,
Gray, Green, Violet, Tan, Orange, Brown. The Right Arrow travels from Blue to Brown. The Left Arrow travels from Brown to Blue.
6 HEAD HARNESS CONNECTIONS
When viewing the vehicle from the rear, the ArrowStik harness is connected in the following order from Driver side to Passenger side: Yellow, Gray,
Green, Violet, Tan, Orange. The Right Arrow travels from Yellow to Orange. The Left Arrow travels from Orange to Yellow.
If the Siren ArrowStik function is congured for ArrowStik End Flash, the Blue and Brown wires will attach to the two end light heads.
5 HEAD HARNESS CONNECTIONS
When viewing the vehicle from the rear, the ArrowStik harness is connected in the following order from Driver side to Passenger side: Yellow, Gray,
Violet, Tan, Orange. The Right Arrow travels from Yellow to Orange. The Left Arrow travels from Orange to Yellow.
If the Siren ArrowStik function is congured for ArrowStik End Flash, the Blue and Brown wires will attach to the two end light heads.
DIM Control
The Siren DIM function supplies +12VDC output when active. This output is compatible with the dimming input of older Code 3 ArrowStik prod-
ucts. It is not used with newer Code 3 ArrowStik products. This output can supply an absolute maximum of 1.5 amps.
Programming
The Siren will come from the factory set to control a CC ArrowStik. For details about ArrowStik pattern selection for Code 3 CC Lightbars, refer to
the Lightbar user manual. For an conventional ArrowStik, refer to the Siren Conguration Software Manual.
