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.
Safety First
This document provides all the necessary information to allow your Whelen product to be properly and safely installed. Before beginning the installation and/or
operation of your new product, the installation technician and operator must read this manual completely. Important information is contained herein that could

Power Switch
This switch has two positions. Down - Off & Up - On. When this switch is
off, siren functions are disabled.
Rotary Switch
The Rotary Switch controls the siren functions of the Epsilon™ 2S7. There
are 7 positions to select from (See “Rotary Switch Operations”).
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.
MAN Button
The Manual button generates a variety of tones, depending on what
position the rotary knob is in (See “Rotary Switch Operations”).
HORN Button
Whenever the siren is ON, pressing the HORN button will generate a
simulated airhorn tone regardless of the ROTARY SWITCH position.
Diagnostic Indicator:
While this siren is under normal use the diagnostic indicator is used to
indicate fault conditions with your siren system. The following section lists
the type of fault and indicators response. If the indicator is on steady while
a tone is in use, this implies that there is no fault with the speaker output.
Fault Condition Diagnostic Indicators Response
Speaker Short Circuit: The speaker LED will be in a single flash mode
(LED is on and off an equal amount of time) and siren tones won’t operate.
Speaker Undercurrent: Speaker LED will be off. All tones will continue to
operate.
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.
Power distribution switches:
The power distribution switches include the slide switch and the four
rocker switches. The slide switch having one off position and three active
positions combined with the four rocker switches makes a total of seven
switch positions. For each of the four rocker switches there are a set of
corresponding WHITE and BLUE or VIOLET and BROWN wires in the
back of the unit (See wiring diagram).
To obtain proper operation of the LED indicator with the switches, connect
the BROWN or BLUE wire to power through a user supplied fuse and
connect the load to the WHITE or VIOLET wire (See wiring diagram).
The slide switch controls three relays. The normally open contact of the
relays are extended through the back panel with the GREEN, YELLOW
and ORANGE wires. The 10 AWG RED wire is connected to the input side
of all the relays
The slide switch can be programmed so that any of the three active
positions can activate any combination of the relay outputs (See Slide
Switch Programming). The factory default operation is as follows:
Rotary Switch Operations:
This section will outline the operation of the siren in the factory default
configuration. Refer to “Programming the Epsilon™ 2S7 Siren” for
information on how to customize the operation of this siren.
RAD - Radio Repeat: With the rotary switch in the RAD position, any
signal that is received by the 2-way radio will be simultaneously broadcast
over the vehicles loudspeaker (The unit must be connected to the 2-way
radio as outlined in this manual).
With the Rotary Switch in this Position:
Pressing the MAN button or activating either the HORN RING or AUX
OVERRIDE input will produce the AIRHORN tone. The AIRHORN tone
will stop when the input is released.
MAN 1 - Manual Siren #1: With the rotary switch in this position the
siren is on standby. No tones will be activated until an action is taken by
the operator.
With the Rotary Switch in this Position:
Pressing the MAN button or activating either the AUX ENABLE or HORN
RING input will produce a WAIL tone. The WAIL tone will ramp up to peak
frequency, then ramp back down and stop when the input is released.
MAN 2 - Manual Siren #2: With the rotary switch in this position the
siren is in standby. No tones will be activated until an action is taken by the
operator.
With the Rotary Switch in this Position:
Pressing the MAN switch or activating either the HORN RING or AUX
OVERRIDE input will produce a WAIL tone. This tone will ramp up to peak
frequency and stop when the input is released.
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 a single tap 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 a WAIL tone (a steady rise
and fall tone). A second tap produces a YELP tone (a fast rise and fall
tone). A third tap produces a piercer tone (an extremely fast rise and fall
tone). The next tap returns the siren to a wail tone and the cycle repeats
itself. Two quick successive taps will stop the siren.
With the Rotary Switch in this Position:
Pressing the MAN button or activating either the HORN RING or AUX
OVERRIDE input will produce the HF cycle.
T1 - Tone #1: When the rotary knob is in the T1 position, a steady, rise
and fall tone (WAIL) is produced.
With the Rotary Switch in this Position:
Pressing the MAN button or activating either the HORN RING or AUX
OVERRIDE will change the siren tone to a YELP pattern (fast rise and fall
tone). Activating the input a second time returns the tone back to WAIL.
T2 - Tone #2: When the rotary knob is in the T2 position, a fast, rise and
fall tone (YELP) is produced.
With the Rotary Switch in this Position:
Pressing the MAN button or activating either the HORN RING or AUX
OVERRIDE input will produce the PIERCER tone. Pressing the MAN
button a second time returns it back to YELP.
T3 - Tone #3: When the rotary knob is in the T3 position, an extremely
fast, rise and fall tone is produced.
With the Rotary Switch in this Position:
Pressing the MAN button or activating the HORN RING or AUX OVER-
RIDE input will result in the AIRHORN tone until the input is released.
