Installation
The 295HFSC9 is designed to be mounted directly onto the dash or other
surface through the use of a bail strap mounting bracket. The unit may
also be mounted into your vehicle’s console (if so equipped). Regardless
of the style selected, be sure to observe the air bag warning on the
cover of this manual.
Bail Strap Mount
1. Position the bail strap in the selected mounting location. Using an awl
or other suitable tool, scribe the surface where the mounting holes
are to be drilled.
Caution: As mounting this unit will require drilling, it is
absolutely necessary to make sure that no other
vehicle components could be damaged in the
process. Check both sides of the mounting
surface before starting. If damage is likely,
select a different mounting location.
• Harmonically-rich, composite
Airhorn tones.
• Title 13-compliant profiles.
• Independent, non-destructive short
circuit protection.
5. Place the unit into its mounted position. Align the theaded holes in
the case with the desired holes in the bail strap.
6. Thread the screws into the case and tighten firmly.
2. Drill the mounting holes in the areas scribed in step 1. The size of the
drill bit should be determined by the size of the mounting hardware
used and thickness of the mounting surface.
3. Secure the bail strap to the mounting location.
Note: There are 2 sets of holes on the bail strap for
positioning the unit at 2 different heights.
4. Locate the two, 1/4-20 x 5/8” screws, two 1/4” internal tooth
lockwashers & two 1/4” split-lockwashers (included). Place the
internal tooth lockwashers between the desired holes in the strap
and the housing. Place the split-lockwashers onto the screws as
shown.
Console Mount
Console manufacturers offer mounting kits that include all the necessary
hardware and brackets required to mount this unit into their console. The
console mount brackets are secured onto the unit the same way the bail
bracket does (except for the addition of two flat washers that must be
inserted between the 295HFSC9 and the bracket). Please refer to the
manual included with your console for specific information on securing the
295HFSC9/mounting bracket assembly onto the console.
NOTE: Due to the lack of air flow within a console, prolonged
operation of this siren will require the console to be modified to
improve ventilation.
Microphone
A 1/4” port is provided on the front right-hand side of the unit for
installation of the microphone.

Wiring
Connecting to Power:
1. Using appropriately sized wire, extend the RED and BLACK wires
from the Main Power Connector, through the firewall and into the
engine compartment (refer to the Wire Gage Calculation Chart
located on the last page of this manual to determine the proper wire
size for your application).
2. Follow the factory wiring harness towards your vehicle’s battery.
WARNING! All customer supplied wires that connect to the positive
terminal of the battery must be sized to supply at least 125% of the
maximum operating current and FUSED
load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
3. Install a user supplied 20A fuse block on the end of the RED wire.
Connect the fuse block to the battery using no more than 2 feet of
wire. Do not install the fuse into the fuse holder yet!
4. Connect the BLACK wire directly to the NEGATIVE battery terminal.
Connecting to your Speaker(s):
1. Route the ORG, WHT/ORG, YEL and WHT/YEL wires (harness
connector positions 5, 6, 7 & 8) along the factory wiring harness
towards your speakers.
2. Connect the ORG wire (pos 6) to the POSITIVE (+) terminal on
speaker #1. Connect the YEL wire (pos 8) to the POSITIVE (+)
terminal on speaker #2.

at the battery to carry that
Hands-Free Siren (optional):
Refer to the wiring diagram for all wiring information for this optional
connection.
Radio Rebroadcast (optional):
The two (2) BLU wires are used to connect your two-way radio’s external
speaker for radio rebroadcast. This is an optional connection and will not
effect the other operations.
Radio rebroadcast volume can be adjusted from the rear as shown below.
Note: Radio rebroadcast will NOT work with amplified remote
speakers! If your remote speaker is amplified (I.E.: contains a power
amp circuit in the speaker assembly), do not enable the radio rebroadcast feature.
Backlight (optional):
Connecting the WHT wire to an ignition-controlled circuit enables
backlighting when the unit’s power switch is off.
Installation will be complete after a 20A fuse has been installed in the Main
Power Connector fuse block. Now inspect the fuses on the bottom of the
unit and at the battery. If any of these fuses are blown, carefully inspect all
of the circuit wires and make sure they are wired correctly. Replace the
blown fuses with ones of an identical amp rating. If these fuses blow after
installation or activation, contact Whelen Engineering Technical Support.

Features
Stereo/Mono Sound Control - The 295HFSC9 power switch has three
positions; Center (Off), Down (On/Mono) & Up (On/Dual). When this
switch is Off, the unit will not function. When the switch is in either On
position, the siren is functional and may be activated at the operator’s
discretion. In the On/Mono position, speakers #1 & #2 will produce
identical siren tones. In the On/Dual position, speakers #1 & #2 can be
configured to simultaneously produce completely different siren tones
(refer to the siren configuration tables for detailed configuration settings).
NOTE: If the unit is connected to the vehicle’s horn ring circuit, the vehicle
horn is disabled when the power switch is in the ON position.
Park-Kill Siren Shutdown - This feature allows the operator to disable an
active siren whenever the transmission is placed in Park. To enable this
feature, the WHT/BRN wire is connected to the output signal of the
transmission’s park/neutral safety switch. To restore normal siren
operation, turn the rotary knob to HF, MAN, STBY or RAD. The siren is
now reset for normal operation. IMPORTANT! This feature may effect
the vehicle warranty. Whelen Engineering recommends that the
vehicle manufacturer be contacted to learn what effect, if any, this
product will have on warranty considerations.

“Siren In Use” Output Signal - This feature provides an output signal that
is active whenever a repetitive cycling siren tone is active (ex. Wail, Yelp,
Piercer). This output signal is not enabled with Airhorn or manual tone
activation.
Hands-Free Operation - This feature offers the ability to activate siren
tones using the vehicle’s steering wheel horn ring. When the rotary knob is
in the HF position, the siren functions are placed in a standby mode. Siren
tones are activated by a single “tap” on the MAN button or on the vehicle’s
steering wheel horn button (if the vehicle’s horn has been wired to the
siren).
Independant Short Circuit Control - This feature implements nondestructive, short circuit protection into the siren design. If one speaker
was to short, the other speaker will remain fully operational and
unaffected. When the short has been resolved, that speaker will
automatically return to normal operation.

Rotary Knob
The Rotary Knob controls the siren functions. There are 7 positions that may be
selected. Each position and its function is outlined under “Rotary Switch Operations.”
Volume Knob, Man Button and Airhorn Button
09-0464120-00
The Volume Knob controls the volume of Public Address function. Volume is
increased by rotating the knob in a clockwise direction. Rotating the volume knob in a
counter-clockwise direction decreases the volume produced by these features. The
volume knob has no effect on any siren tones produced.
The Manual button generates a variety of tones, depending on what position the
rotary knob is in. For further explanation of this button’s function, refer to “Rotary
Switch Operations.”
Holding the AIRHORN button on, generates an AIRHORN tone whenever the siren is
powered up.
Rotary Switch Operations:
RAD (Radio Repeat) - When the rotary knob is in the RAD position, any
signal that is received by the vehicle’s two-way radio will be
simultaneously broadcast over the vehicle’s loudspeaker (unit must be
connected to the two-way radio as outlined in this manual).
With the Rotary Switch in the RAD Position:
• Activating the HORN RING will activate the VEHICLE HORN until the
HORN RING is released (assuming the the horn ring transfer relay is
wired as shown in the wiring diagram).
• Pressing the AIRHORN button will result in an AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button results in the AIRHORN tone until the MAN
button is released.
STDBY (Manual Siren) - When the rotary switch is in this position the
siren is in a standby state where no tones have been activated, but is
waiting for another action to be taken by the operator. This position is often
the best choice when manual operation of the siren is desired.
With the Rotary Switch in the STDBY Position:
• Activating the HORN RING will produce a AIRHORN tone until the
HORN RING input is released.
• Pressing the AIRHORN button will result in the AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button will result in the Manual Wail tone ramping up
to peak frequency and ramping down when the MAN button is released.
MAN (Manual Siren) - When the rotary switch is in this position the siren
is in a standby state where no tones have been activated, but is waiting for
another action to be taken by the operator. This position is used when
manual operation of the siren is desired.
With the Rotary Switch in the MAN Position:
• Activating the HORN RING will result in a Manual Wail tone ramping up
to the peak frequency and stopping when the HORN RING input is
released.
• Pressing the AIRHORN button produces an AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button has the same effect as pressing the HORN
RING.
HF (Hands-Free Operation) - When the rotary knob is in the HF position,
the siren functions are placed in a stand-by mode. Siren tones are
activated by a single “tap” on the MAN button or on the vehicle’s steering
wheel horn ring (if the vehicle’s horn has been wired to the HORN RING
input). The first tap produces Tone 1. A second tap produces Tone 2. A
third tap produces Tone 3. The next tap returns the siren to Tone 1 and the
cycle repeats itself. Two quick successive taps will stop the siren (refer to
the tables on the following pages for hands-free tonal information).
With the Rotary Switch in the HF Position:
• Activating the HORN RING will result in the HF cycle as described
above.
• Pressing the AIRHORN button will result in the AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button will result in the HF cycle as described above.
WAIL (Wail Tone) - When the rotary knob is in the WAIL position, a
steady, rise and fall wail tone is produced.
With the Rotary Switch in the WAIL Position:
• Activating the HORN RING will change the siren tone to the override
tone. Activating the HORN RING a second time returns it back to a
WAIL .
• Pressing the AIRHORN button will result in an AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button will change the siren tone to the override tone.
Pressing the MAN button again returns it back to a WAIL.
YELP (Yelp Tone) - When the rotary knob is in the YELP position, a fast,
rise and fall tone is produced.
With the Rotary Switch in the YELP Position:
• Activating the HORN RING will change the siren tone to the override
tone. Activating the HORN RING a second time returns it back to a
YELP tone.
• Pressing the AIRHORN button will result in the AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button will change the siren tone to the override tone.
Pressing the MAN button a second time returns it back to a YELP tone.
T3 (Piercer
TM
Tone (see dip switch tables)) - When the rotary knob is in
the T3 position, an extremely fast, rise and fall tone is produced.
With the Rotary Switch in the T3 Position:
• Activating the HORN RING will produce the override tone until the
HORN RING is released.
• Pressing the AIRHORN button will result in an AIRHORN tone until the
AIRHORN button is released.
• Pressing the MAN button will produce the override tone until the MAN
button is released.
Refer to the siren tables on the following pages for override tone
details.
MICROPHONE - Whenever the unit is powered on, activating the
microphone (pressing the switch on the side of the mic.) will shut down
any other siren functions & enable public address operation regardless of
the rotary switch position or any other switch or input.

To use this chart...
1. Determine the amount of current being drawn through the wire. Locate this number in the vertical left-hand
column. If the current value is between adjacent values, use the higher number.
2. Follow this row until the length of the installed wire is shown. If the exact length is between adjacent values, use
the higher number. Follow this column upwards to find the recommended size (gage) for this wire.
In the example shown below, the size for a wire with an installed length of 36 feet, through which 22 amps of current
will be drawn, must be determined.
A row for 22 amps is not shown, so the row for 25 amps will be used. Follow this row to the right. A column for 36 feet
is not shown, so the column for 49.5 feet will be used. Following this column to the top will show that the size of this
wire must be at least 6 gage.
