Warnings to Installers
Whelen’s emergency vehicle warning devices must be properly mounted and wired in order to be effective and safe. Read and follow all of Whelen’s written
instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for
when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without
taking their eyes off the roadway. Emergency warning devices can 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 vehicle
damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after
installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other
components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio
communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of
sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This
device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment
area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its
mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a
method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow
instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. 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.
Warnings to Users
Whelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and
personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other
drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely
before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning
devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible
warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility
to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of
any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle
occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and
operated in accordance with the standards established by the National Fire Protection Association.

Two BLUE wires - Radio Rebroadcast (optional):
The two remaining BLUE wires are used to connect your two-way radio’s
external speaker for radio rebroadcast (optional connection).
Note: If your remote speaker is amplified (speaker has a power amp circuit),
radio rebroadcast will not work and should not be used.
1. Locate the 2 wires that connect the external speaker to the 2-way
radio, cut one of them and splice one of the BLUE wires into this
circuit.
2. Cut the remaining speaker wire and splice the other BLUE wire into
this circuit.
VIOLET - Siren Interruption:
Grounding the VIOLET wire will deactivate the siren. The siren can be
programmed to reactivate the tones by 2 different methods (See section
6.3) This wire doesn’t affect HORN or MAN push button operations.
2.2 PINS 10, 11 & 12:
GREEN - Aux Enable:
This wire is activated in slide switch position 3, if switch1 of BANK-1 is
down.
ORANGE - Siren in Use:
Extend the ORANGE to the icon input of a video camera. This wire is
active positive whenever a siren tone is being produced (200ma max).
YELLOW - Backlighting:
Extend the YELLOW to the parking light positive voltage. This input is
used to drive the backlighting of the siren when the power is off.
Alternate Slide Switch Control:
In factory default setup, the slide switch’s common power terminal is
connected to the BROWN wire on P1. By changing a fuse (located by
removing the cover of the siren) from the F4_F2 position to the F1_F2
position, the slide switch’s common power terminal can be configured to
get it’s power from the RED wire of P1 which is used to power the six push
button switches.
3.0 Front Panel:
3.1 Power Switch
This switch has two positions; Up (On) and Down (Off). When this switch
is off, siren functions are disabled, however the power distribution switch-
ing can operate independently of the power switch.
WARNING! If the this unit is connected to the vehicle’s horn ring
circuit, the vehicle horn is disabled when the power switch is ON.
3.2 Rotary Switch
The Rotary Knob controls the siren functions of the 295SLSA5. There are
7 positions that may be selected (see Section 4.0.).
3.3 Volume Knob
The Volume Knob controls the volume of Public Address function. Volume
is increased by rotating the knob in a clockwise direction. Rotating the Vol-
ume Knob in a counter-clockwise direction decreases the volume pro-
duced by these features. The
volume knob has no effect on siren tones or radio repeat volume.
3.4 Radio Repeat Volume
Before using the 295SLSA5, the Radio Repeat output volume must be
adjusted to satisfactory operating levels. To adjust this level, a small, flat-
blade screwdriver is needed. Locate the Radio Repeat adjustment port
(potentiometer) to the right of the Rotary Knob on the face of the control
head. Set the volume level of the vehicle’s two-way radio to its normal
operating volume. Turn the Rotary Knob on the control head to RAD to
activate Radio Repeat. Insert the screwdriver in the Radio Repeat adjust-
ment port and turn in a clockwise direction to increase the sound level.
3.5 MAN Button
The Manual button generates a variety of tones, depending on what posi-
tion the rotary knob is in (see Section 4.0.).
3.6 SI TEST® & Diagnostic Indicators
SI TEST is a diagnostic feature of the 295SLSA5 and allows the operator
to confirm the proper operation of the siren speakers connected to the unit
without activating an audible siren tone. To initiate SI TEST cycle, set the
rotary knob to the RAD position. Now press and release the MAN button.
As the siren is tested, its diagnostic indicator will turn on steady for about
1.5 seconds if no problems are detected. If the indicator flashes, or does
not light at all, a problem with either the siren, speakers, or wiring has
been detected. Check the wire connections of the failed speaker and
repeat the SI TEST. If the speaker fails to test again, have the siren itself
inspected by a qualified technician. NOTE: Installed speakers are tested
by generating an ultra-high frequency tone through each speaker.
Although these tones are inaudible to humans, be sure no one is within 5
feet of the speakers when SI TEST is running.
Diagnostic Indicators:
While this siren is under normal use the diagnostic indicators are used to
indicate fault conditions with your siren system. The following table lists
the type of fault and the indicators response. If the indicator is on steady
while a tone is in use, this implies that there is no fault with the associated
speaker output.
Fault Condition Diagnostic Indicators Response
Under Voltage Speaker LED #2 will be in a DoubleFlash mode (2 quick
flashes followed by a longer pause) and siren tones
won’t operate.
Over Voltage Speaker LED #1 will be in a DoubleFlash mode (2 quick
flashes followed by a longer pause) and siren tones will
not operate.
Speaker #1 Speaker LED # 1 will be in a SingleFlash mode (the LED
Short Circuit will be on and off an equal amount of time) and siren
tones won’t operate.
Speaker #2 Speaker LED #2 will be in a SingleFlash mode (the LED
Short Circuit will be on and off an equal amount of time) and siren
tones won’t operate.
Speaker #1 Speaker LED #1 will be off (having a single speaker
Open Circuit system will always cause this condition for the speaker
output not in use) all tones will continue to operate.
Speaker #2 Speaker LED #2 will be off (having a single speaker
Open Circuit system will always cause this condition for the speaker
output not in use) and all tones will continue to operate.

3.7 Horn Button
Power up the siren and hold the HORN button on to generate an AIR-
HORN tone.
3.8 Programmable Power Switches:
The power distribution switches include the slide switch and the six
switches. The slide switch having one off position and three active posi-
tions combined with five push on push off and one momentary switch
makes a total of nine switch positions. For each of the nine switches there
are corresponding outputs on the P1 connector in the back of the unit.
Each of the nine switches will always activate it’s own corresponding out-
put, but the slide switch can be programmed to activate any of the other
outputs. (See Section 5.0).
3.9 Microphone:
Whenever the siren is on, activating the microphone (pressing the switch
on the side of the mic.) will shut down any other siren functions and enable
public address operation regardless of the rotary switch position or any
other switch or input.
4.0 Rotary Switch Operations:

5.0 Switch Operation:
5.1 Custom Dip Switch Configuration (BANK1):
Push-button 9 (momentary switch) can function in 4 different modes,
defined by the 4-position dip switch 1 (BANK1) (Fig. 2).
Mode 1 - (default) - In this configuration, the output is activated for as long
as push-button 9 is depressed.
Mode 2 - In this configuration, when push-button 9 is pressed, the output
is activated for a period of 8 seconds.
Mode 3 - In this configuration, when push-button 9 is pressed, the output
is activated. When pressed again, the output is deactivated.
Mode 4 - In this configuration, when push-button 9 is pressed, the output
is activated for a period of 400 ms. After 400 ms, the output is deactivated
for 400 ms. This cycle will continue until push-button 9 is pressed again.
Bank 1 Position 1
Enabling siren tones through slide switch position #3:
Slide switch position 3 can be configured to automatically activate siren
tones (See Section 4.0 - Rotary Switch Operations). If this is not desired,
make sure that Dip Switch Bank 1 position 1 is in the off position (the
factory default position). Please note that siren activation through slide
switch position 3 is only available when the power switch is in the ON
position.
5.2 Configuring the Slide Switch Functions:
In the default dip switch setting, the P1 outputs are:
Slide Switch Positions: Push-Buttons:
0 = ALL OFF 4 = WHT/YEL
1 = WHT/BRN 5 = WHT/GRN
2 = WHT/RED, WHT/BRN 6 = WHT/BLU
3 = WHT/BRN, WHT/RED, WHT/ORG 7 = WHT/VIO
8 = WHT/GRY
9 = WHT
Changing Default Slide Switch Control:
The slide switch has four positions: 0 (off), 1, 2 & 3. When in position 0
(furthest to the left) the slide switch will not activate any outputs. In
position 1, 2 or 3 the slide switch can activate any combination of outputs
1 through 8. Each active slide switch position uses a bank of dip switches
to determine which outputs are to be active while the slide switch is in that
position; position 1 uses BANK4, position 2 uses BANK3, and position 3
uses BANK2 (Fig. 2).
Each dip switch bank is comprised of 8
switches, each representing a
corresponding output (DIPSW-1 for
WHT/BRN, DIPSW-2 for WHT/RED,
etc.). If, for example, switches 1, 3, 4 & 6
on BANK4 are in the ON position, outputs
WHT/BRN, WHT/ORG, WHT/YEL, WHT/
BLU will be active when the slide switch
is moved to position 1.
Slide switch configuration can be
accomplished by deciding which outputs
are to be active in a given position and then moving the corresponding dip
switch on the appropriate dip switch bank to the ON position.
