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.

Factory Default Operations:
The operations described in this section are the factory default
settings that the unit is shipped with. To change the settings, refer
to Programming the 295SDA2 for information on how to
customize the operation of the siren/lighting control center.
Siren Operations
RAD - Radio Rebroadcast:
When this button is pressed, any signal that is received by the
vehicle’s two-way radio will be simultaneously broadcast over the
vehicle’s loudspeaker (the unit must be connected to the two-way
radio as outlined in this manual). Pressing the RAD button again will
deactivate it.
With the Radio Rebroadcast (RAD) button activated:
• Activating the A/H button will produce a higher frequency AIRHORN
tone on speaker 1 and a Lower frequency AIRHORN tone on speaker 2
until released.
• Activating the SIR or H/F button will deactivate the RAD button and
produce their corresponding function.
• Activating the HORN RING input will produce the cars horn until the
HORN RING switch is released.
• Activating the SIREN DISABLE input has no effect.
SIR - Wail tone:
When this button is pressed, the siren will produce a synchronized Wail
tone on both speakers. Pressing the SIR button again will deactivate it.

Page 4
With the Siren (SIR) button activated:
• Activating the A/H button will produce a higher frequency AIRHORN
tone on speaker 1 and a Lower frequency AIRHORN tone on speaker 2
until released.
• Activating the RAD or H/F button will deactivate the SIR button and
produce their corresponding function.
• Activating the HORN RING input or MAN button will change the siren
tone to two out of sync WAIL tones. Activating the HORN RING input or
MAN button a second time returns it back to synchronized WAIL tones
on both speakers
• Activating the SIREN DISABLE input will deactivate the SIR button.
H/F – Hands Free:
When you press H/F the siren functions are placed in a stand-by mode.
Siren tones are activated by a single “tap” on the MAN button or the
vehicle’s steering wheel horn ring (if the vehicle’s horn has been wired to
the HORN RING input). The first tap produces two “Phased” Wail tones on
both speakers. A second tap produces two “Phased” Yelp tones on both
speakers. A third tap produces a Yelp tone on speaker 1 and a Piercer™
tone on speaker 2. The next tap returns the siren to the “Phased” Wail
tones and the cycle repeats itself. Two quick successive taps stop the
siren.
With the Hands Free (H/F) button activated:
• Activating the A/H button will produce a higher frequency AIRHORN
tone on speaker 1 and a Lower frequency AIRHORN tone on speaker 2
until released.
• Activating the RAD or SIR button will deactivate the STANDBY button
and produce their corresponding function.
• Activating the HORN RING input or MAN button will produce the hands
free cycle as described above.
• Activating the SIREN DISABLE input will deactivate the H/F button.
MAN – Manual Wail:
When no other siren buttons are activated, pressing the MAN button
generates two “Phased” Wail tones on both speakers that rises in pitch to
a pre-set level. This tone is generated for as long as the Manual button is
pressed. When the button is released the tone coasts down in frequency
to a pre-set level and stops.
A/H – Airhorn tone:
• Activating the A/H button will always produce a higher frequency
AIRHORN tone on speaker 1 and a Lower frequency AIRHORN tone
on speaker 2 until released.
MICROPHONE – Public address:
• Activating the Push To Talk switch on the microphone will put speaker 1
in public address operation and will momentarily shut down any other
siren function until the switch is released.
Lighting Control Operations:
Lighting Control Switches: The lighting control switches include switches
SL1-3, and SW5-8 for a total of 7 lighting control switch positions. For
each of the 7 switches there are corresponding relay controlled outputs on
the connectors of J1 and J2 (see wiring diagram). The following list
describes the Factory Default switch activated outputs.
Traffic Advisor Control
There are two programmable “Switch Types” associated with Traffic
Advisor control, “Traffic Advisor Pattern Control” and “Traffic Advisor
Flash Control”.
When a switch’s “Switch Type” has been programmed as “Traffic Advisor
Pattern Control”, this switch now takes control of designated Traffic
Advisor output J2 pin 4 (white yellow) and the associated relay output of
the programmed switch. These two wires connect to the traffic advisor.
The first press of this switch will produce a Left sweep on the Traffic
Advisor, and will turn off a “Traffic Advisor Flash Control” switch if one is
active.
A second press will produce a right arrow.
A third press will produce a split arrow.
The next press returns the unit to Left arrow and the cycle repeats itself.
Holding the switch down for 2 seconds will shut the arrow off.
NOTE: Only one switch can be programmed as a “Traffic Advisor
Pattern Control” switch, If more than one switch is programmed,
unpredictable results will occur.
When a switch’s “Switch Type” is programmed as “Traffic Advisor Flash
Control”:
Pressing this switch will produce a flash pattern on the Traffic Advisor
indicator, will turn off a “Traffic Advisor Pattern Control” switch if one is
active, and the relay output programmed for the “Traffic Advisor Flash
Control” switch will turn on.
Pressing this switch again will shut the arrow off.
NOTE: Only one switch can be designated as a “Traffic Advisor
Flash Control” switch, If more than one switch is programmed,
unpredictable results will occur.
Alley Cycle (ALY)
Switch SW5 on the control head is set up to operate the Alley cycle, and
controls outlets J1 pin 7 and pin 9 on the amplifier, and is intended to
control the Alley lights on a lightbar. The outputs are controlled as follows:
1st Press - Activates J1 pin 9, WHT/ORG (Left alley).
2nd Press - Deactivates J1 pin 9, WHT/ORG & Activates J1 pin 7, WHT/
BRN (Right alley).
