To download copies of this manual, go to www.fedsig.com or call the Federal Signal Service Department at 1-800-433-9132, 7 a.m. to 5 p.m., Monday through Friday (CT).

Safety Messages to Installers of Federal Signal Sound/Light Systems

People’s lives depend on your proper installation and servicing of Federal Signal products. It is important to read and follow all instructions shipped with this product. In addition, listed below are some other

important safety instructions and precautions you should follow:

Before Installation

Qualications

• To properly install an electronic siren, you must have a good understanding of automotive electrical procedures and systems, along with prociency in the installation and service of safety warning equipment. Always refer to the vehicle’s service manuals when performing equipment installations on

a vehicle.

Sound Hazards

• Your hearing and the hearing of others, in or close to your emergency vehicle, could be damaged

by loud sounds. This can occur from short exposures to very loud sounds, or from longer exposures

to moderately loud sounds. For hearing conservation guidance, refer to federal, state, or local

recommendations. OSHA Standard 1910.95 offers guidance on “Permissible Noise Exposure.”

• All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing loss. Always minimize your exposure to siren sound and wear hearing protection. Do not sound the siren

indoors or in enclosed areas where you and others will be exposed to the sound.

• Federal Signal siren ampliers and speakers are designed to work together as a system. Combining

a siren and speaker from different manufacturers may reduce the warning effectiveness of the siren system and may damage the components. You should verify or test your combination to make sure the system works together properly and meets federal, state and local standards or guidelines.

Chapter 1: Safety Messages for Installers and Operators

During Installation

• Do NOT get metal shavings inside the product. Metal shavings in the product can cause the system

to fail. If drilling must be done near the unit, place an ESD approved cover over the unit to prevent metal shavings from entering the unit. Inspect the unit after mounting to be sure there are no shavings present in or near the unit.

• Do NOT connect this system to the vehicle battery until ALL other electrical connections are made, mounting of all components is complete, and you have veried that no shorts exist. If wiring is shorted to vehicle frame, high current conductors can cause hazardous sparks resulting in electrical res or ying molten metal.

• Be sure the siren amplier and speaker(s) in your installation have compatible wattage ratings.

• In order for the electronic siren to function properly, the ground connection must be made to the

NEGATIVE battery terminal.

• Sound output will be severely reduced if any objects are in front of the speaker. If maximum sound

output is required for your application, you should ensure that the front of the speaker is clear of any

obstructions.

• Install the speaker(s) as far forward on the vehicle as possible, in a location which provides maximum signaling effectiveness and minimizes the sound reaching the vehicle’s occupants. Refer to the National Institute of Justice guide 500-00 for further information.

• Mounting the speakers behind the grille will reduce the sound output and warning effectiveness of the siren system. Before mounting speakers behind the grille, make sure the vehicle operators are trained and understand that this type of installation is less effective for warning others.

• Sound propagation and warning effectiveness will be severely reduced if the speaker is not facing forward. Carefully follow the installation instructions and always install the speaker with the projector facing forward.

• Do NOT install the speaker(s) or route the speaker wires where they may interfere with the operation

of air bag sensors.

• Installation of two speakers requires wiring speakers in phase.

• Never attempt to install aftermarket equipment, which connects to the vehicle wiring, without

reviewing a vehicle wiring diagram available from the vehicle manufacturer. Insure that your

installation will not affect vehicle operation and safety functions or circuits. Always check vehicle for

proper operation after installation.

• Do NOT install equipment or route wiring or cord in the deployment path of an air bag.

• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be recalibrated for proper air bag deployment.

• Locate the control head so the vehicle, controls, and microphone can be operated safely.

• When drilling into a vehicle structure, be sure that both sides of the surface are clear of anything that

could be damaged.

• Test all vehicle functions, including horn operation, vehicle safety functions and vehicle light systems,

to ensure proper operation. Ensure that installation has not affected vehicle operation or changed any vehicle safety function or circuit.

• After testing is complete, provide a copy of these instructions to the instructional staff and all

operating personnel.

• File these instructions in a safe place and refer to them when maintaining or reinstalling the product.

Failure to follow all safety precautions and instructions may result in property damage, serious injury, or death.

RETAIN AND REFER TO THESE MESSAGES

Safety Messages to Operators of Federal Signal Sound/Light Systems

People’s lives depend on your safe operation of Federal Signal products. It is important to read and follow all instructions shipped with the products. In addition, listed below are some other important safety

instructions and precautions you should follow:

• Do not attempt to activate or de-activate the controls of the emergency warning system while driving

in a hazardous situation.

• Although your warning system is operating properly, it may not be completely effective. People

may not see, hear, or heed your warning signal. You must recognize this fact and continue driving

cautiously.

• Also, situations may occur which obstruct your warning signal when natural and man-made objects

are between your vehicle and others, such as raising your hood or trunk lid. If these situations occur, be especially careful.

• All effective sirens and horns produce loud sounds that may cause, in certain situations, permanent

hearing loss. You and your passengers should consider taking appropriate safety precautions, such as wearing hearing protection.

• The effectiveness of an interior mounted warning light depends on the clarity, the tinting, and the

angle of the glass it is being placed behind. Tinting, dirt, defects, and steeply angled glass reduce the light output of the warning light. This may reduce the effectiveness of the light as a warning signal. If

your vehicle has dirty, tinted, or steeply angled glass, use extra caution when driving your vehicle or blocking the right of way with your vehicle.

• In order to be an effective warning device, this product produces bright light that can be hazardous to

your eyesight when viewed at a close range. Do not stare directly into this lighting product at a close range or permanent damage to your eyesight may occur.

e-Q2B Siren System

Page 10

Chapter 1: Safety Messages for Installers and Operators

• It is important that you fully understand how to safely operate this warning system before use.

• You should only operate your vehicle and its light/sound system in accordance with your

department’s Standard Operating Procedures.

• If a selected function does not perform properly or if any of the lamps remain illuminated when the

control is off, disconnect the power connector from the control unit and contact the nearest service center.

• At the start of your shift, you should ensure that the entire warning light system and the siren system

is securely attached and operating properly.

• Suction cup mounting is for temporary applications only. The unit should be removed from the

window and stored securely when not in use. Temperature changes and sunlight can cause suction cups to lose holding power. Periodically check the unit to be sure the suction cups have a rm grip on the mounting surface. An improperly secured light could fall off of the vehicle causing injury and

damage.

• The holding power of magnetic mounting systems is dependent upon surface nish, surface atness,

and thickness of the steel mounting surface. Therefore, to promote proper magnetic mounting:

✓

Mounting surface and magnets must be kept clean, dry, and free of foreign particles that

prevent good surface contact.

✓

Ensure that mounting surface is at.

✓

A magnet mounting system should not be used on vehicles with vinyl tops.

✓

To prevent sliding of light assembly on mounting surface, quick acceleration and hard stops

should be avoided.

Failure to follow these precautions may result in property damage, serious injury, or death.

CHAPTER 2

An Overview of the e-Q2B Siren System

The e-Q2B is a full-featured electronic siren. A state-of the art microprocessor and DSP technology to create a system with a small compact control head and a siren amplier that can be installed in the trunk, under the seat, or under the dash of any vehicle with a 12-volt, negative-ground electrical system. The siren circuits are protected by a replaceable 30 A fuse that protrudes from the siren housing.

e-Q2B Siren System

The e-Q2B is a modular system that includes either one 200-watt speaker or two 100-watt speakers, an amplier/DSP (digital signal processor), and a Convergence™ Network control head. These components

work together to generate the characteristic sound of the Federal Signal Q siren. Using DSP circuitry, the

e-Q2B amplier is able to reproduce the true Q sound, rather than relying on a simple digital recording. The DSP enables the product to function either manually or automatically for hands-free operation.

The Model e-Q2B-200 siren amplier requires two 100-watt neodymium drivers that enable the unit to reproduce the harmonics that are essential for the precise reproduction of the Q sound. T sound ef

and manual siren with brake tones, as well as an air horn sound.

fectively, the e-Q2B produces a full 200 watts of output. The e-Q2B produces wail, yelp, priority,

o deliver the Q

The Model e-Q2B-100 is a 100-watt siren amplier. It incorporates all the features of the standard 200watt siren, but is designed to drive a single 100-watt speaker, such as a Federal Signal Model BP100 or a Model ES100

Siren Speakers

Federal Signal offers speakers for the Model e-Q2B-200 and the Model e-Q2B-100 that meet SAE J1849 and CCR Title 13, Article 22, Class “A” for sound output: the BP200 Series, the BP100 Series, and the ES100.

The Model BP200-Q 200-watt siren speaker mounts ush within the bumper of your vehicle. It has the classic, chrome-plated Q grille. This speaker system enables you to clear trafc with the penetrating

sound of the Q and also allows you to maintain the traditional look of the Q siren when using the optional

Q grille. Also available is the BP200-EF compact 200-watt speaker with an “Electric F” grille, which also mounts ush within the bumper of your vehicle.

The Model BP100 100-watt siren speaker has a compact size that allows it to be mounted on top of or behind the bumper, or installed beyond the grille of popular emergency vehicles. Available in two nishes, the BP100 has a black matte nish and the BP100P is highly polished. The Dynamax ES100 is also an option for increased performance and reliability. The larger diaphragm of the ES100 enables the speaker to capture lower frequency ranges for a more robust sound.

Chapter 2: An Overview of the e-Q2B Siren System

Convergence Network Control Head

The Convergence Network control head digitally transmits and prioritizes end-user commands. The control head/amplier interface uses solid-state digital decoding, which minimizes interconnection complexity. The control head allows the user to operate several siren functions. The traditional Q Wail can be activated in automatic or manual modes. Additional features include a Q Yelp, Q Brake, digitally recorded Air Horn, PA/radio rebroadcast, and push-to-talk via an integral microphone. PA volume can be

adjusted by the user with a volume control potentiometer.

LED Indicators

Green LEDs on the side of the siren amplier indicate when power is supplied to the amplier, when output is available and when a load is connected. Red LEDs indicate a speaker short or thermal overload. All buttons on the control head glow amber when the system is on. Pressed buttons glow brighter to

indicate that the function they control is active.

UNIT REQUIRES AIR FLOW—The siren amplier is cooled by an internal fan. Do not install it in areas where the air ow is restricted. Do not mount the unit near a

heater duct or under the hood.

UNIT IS NOT WATERPROOF—The housing of the e-Q2B siren amplier is NOT

waterproof. The module must be mounted in a location that is sheltered from falling rain, snow, standing water, etc.

For the control head, select a mounting location that allows the vehicle, controls, and microphone to be

operated safely under all driving conditions. To identify safe mounting areas for equipment inside the vehicle, consult the vehicle manufacturer’s guidelines. To avoid driver distraction and unreliable switch

activation, the mounting location must not allow any movement of the control head. Do not select a

padded surface for the mounting location of the control head. For the siren amplier, suggested mounting

locations are under the front seat, in a vehicle compartment, or in the trunk under the rear deck near the rear-seat speakers.

Wiring the Siren Amplier

The siren amplier has the following types of Convergence Network connections via cables and locking connectors included with the e-Q2B kit:

■ Three “plug and play” serial ports that communicate on the Federal Signal Convergence network with

the control head, compatible lightbars, and the Federal Signal Model 660100 Relay Module/Two-

Channel Flasher.

■ Speakers

■ Radio rebroadcast

■ Park disable circuit

■ Horn ring circuit

■ Foot switch inputs for CYCLE, BRAKE, and AIR HORN

HIGH CURRENT ARCING—Do not connect this system to the vehicle battery until

ALL other electrical connections are made and you have veried that no shorts

exist. High current conductors can cause hazardous sparks or burning wire

resulting in electrical res.

DRILLING PRECAUTIONS—When drilling holes, check the area into which you are drilling to be sure that you do not damage vehicle components while drilling. All drilled holes should be de-burred and all sharp edges should be smoothed. All wiring routings going through drilled holes should be protected by a grommet or convolute/split loom tubing.

To prepare the vehicle for the electrical installation of the e-Q2B Siren System:

After planning where to route the wires and cables for the e-Q2B Siren System components—such

as Federal Signal warning lights, directional lights, and speakers—drill the holes for the wiring.

Smooth, de-burr, and insert a grommet in each hole. Use a silicone sealant where needed.

Route wires from the system components through the vehicle to their connection points.

The next sections describe how to connect and wire each system component to the siren amplier:

Connecting to the Serial Ports

There are three network ports on the upper right corner of the front of the siren amplier. The ports connect Federal Signal network devices through RS-485 communication cables. To connect the control head, use the 25-foot FS Conver

instructions included with the products after you connect all system devices.

gence Network cable (P/N 1751357-02).

To connect the serial devices:

Carefully route the cables from the network devices through the vehicle to the connectors on

the siren amplier.

Connecting Speakers to the e-Q2B

SOUND HAZARD—All effective sirens and horns produce loud sounds produce loud sounds (120 dB) that may cause permanent hearing loss. Always minimize your exposure to siren and horn sounds and wear hearing protection. Do not sound the siren or horn indoors or in enclosed areas where you and others will be exposed to the sound.

SPEAKER CONNECTIONS—For proper operation and performance, always connect the speakers in parallel and in phase.

The Model e-Q2B-200 operates one 200-watt speaker or two 100-watt speakers with an impedance of 11 ohms. The Model e-Q2B-100 operates one 100-watt speaker with an impedance of 11 ohms.

The e-Q2B-200 siren amplier is designed to operate optimally with a Federal Signal BP200-Q or BP200-EF 200-watt speaker system, which is not included as part of the electronic siren. This speaker system incorporates two 11-ohm, 100-watt neodymium drivers to produce a full 200 watts of output. If you are using a speaker system comprising two 11-ohm, 100 W speakers, connect the

speakers as shown in Figure 3.6 on page 22.

Federal Signal speakers are weatherproof and may be installed in any unobstructed convenient

location: on the fender, behind the grill, etc. Any special mounting instructions applicable to the type

of speaker you have chosen will be found in the speaker carton.

A 20-foot speaker cable is included with Federal Signal BP200 Series speakers. The cable has a waterproof connector on one end that connects to the speaker. The other end of the cable is supplied

un-terminated.

Connecting the BP200 Speaker to the e-Q2B-200

To connect the 200-watt speaker system to the Model e-Q2B-200 siren amplier:

1. Mount the e-Q2B Siren System components according to the instructions included with each product.

Connect the waterproof connector to the speaker and route the speaker cable through the

vehicle compartment to the amplier.

Connecting the e-Q2B to the Rumbler 2 Low Frequency Amplier

The e-Q2B has a Rumbler audio output that enables it to interface to a Federal Signal Rumbler 2 siren amplier. The Rumbler 2 intersection-clearing system uses the output of the e-Q2B siren amplier to synthesize a low frequency signal. It then amplies the signal to drive a Federal Signal low-frequency siren speaker. Low frequency tones have the distinct advantage of penetrating solid

materials, enabling vehicle operators and nearby pedestrians to feel the sound waves.

Figure 3.9 on page 25 shows the connections between the Rumbler 2 and the e-Q2B siren amplier.

For more details, see

Enabling the Horn-Ring Transfer of Siren Tones

The e-Q2B horn-ring transfer function uses the vehicle horn switch to toggle between siren tones. For more information on how this function operates, see “Horn Ring” on page 46 for the standard e-Q2B Siren System. For the e-Q2B-CAL Siren system, see “Horn Ring” on page 50.

NOTE: The 12-position tension-clamp connector accepts 18 AWG to 22 AWG wire. The

recommended length of insulation to strip from the wires for insertion into the connector is

0.275 in (0.7 mm).

To enable the horn-ring control of siren tones:

Locate the vehicle horn relay.

2. Route wire from the RING and HORN connectors on the front of the siren amplier to the

relay (Figure 3.10 on page 27). If possible, follow the factory wire harness to the relay.

The cable uses a three-position male connector The installer-supplied red (positive) and black (negative ground) power leads from the siren amplier to the vehicle battery should be as short and direct as possible. Required are an installer-supplied in-line fuse and wiring of an amperage capacity sufcient to handle the total vehicle electrical loads.

BATTERY EXPLOSION—To avoid a battery explosion, always disconnect the

negative battery cable rst and reconnect it last. Avoid causing a spark when

connecting near or to the battery. The gases produced by a battery can cause a battery explosion that could result in vehicle damage and serious injury.

HIGH CURRENT ARCING—Do not connect this system to the vehicle battery until

ALL other electrical connections are made and you have veried that no shorts

exist. High current conductors can cause hazardous sparks or burning wire

resulting in electrical res.

Preparing to Connect the Power Leads

Before connecting the amplier/relay module to the battery, ensure that your nal installation goes smoothly by taking these preparatory steps:

Visually check all connections and wiring to ensure that all connections are correct and secure.

2. Ensure that there are no loose strands or other bare wires that may cause a short circuit.

Also, all wires must be protected from any sharp edges that could eventually cut through the

insulation.

Verify that are other electrical connections are completed and that no shorts exit.

4. Use an ohmmeter to verify that a short circuit does not exist between the positive (+) and negative (–) battery cable leads. Also, there must be no short circuits between the positive

wires and the vehicle chassis.

Insulate spliced leads with twist-on wire connectors. Fold and seal unused leads. Use wire ties

and hold-downs for strain relief.

Connecting the Power Leads to the Vehicle Battery

The installer-supplied red (positive) and black (negative ground) power leads from the siren amplier to the vehicle battery should be as short and direct as possible.

Connect the 10 AWG red positive lead (+) to a positive power source capable of supplying

40 amperes. Install a user-supplied 30-ampere fuse (minimum) at the source. The e-Q2B is internally fused at 30 amperes (Figure 3.15 on page 33).

Connect the 10 AWG negative (–) black lead directly to the negative battery terminal.

Connect the 12 AWG white lead with the red stripe to a switched circuit that is hot, or active,

in the ON and START position of the vehicle ignition system. Install a user-supplied 2-ampere

fuse at the source.

CHAPTER 6

Final Preparations of the e-Q2B Siren System

The nal step in the installation of the e-Q2B Siren System is to ensure that the system is installed

correctly, that all vehicle functions operate properly, and that safety stickers and messages are available to vehicle operators. Before proceeding, note the following precautions.

SOUND HAZARD—All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing loss. Always minimize your exposure to sound of the siren and horn, and wear hearing protection. Do not sound the siren and horn indoors or in enclosed areas where you and others will be exposed to the sound.

LIGHT HAZARD—To be an effective warning device, an emergency warning system produces bright light that can be hazardous to your eyesight when viewed at a close range. Do not stare directly into this lighting product at a close range or permanent damage to your eyesight may occur.

Testing the Installation

Test the e-Q2B Siren System to verify that it is operating properly. Be sure to note the status of the LED indicators on the front of the siren amplier (Figure 6.1).

if the system does not function as expected. Test the vehicle only in a controlled environment. After

testing is complete, provide a copy of this manual to the instructional staff and all operating personnel.

Distributing the Safety Message Card

Give the operator of the e-Q2B System the card entitled “Safety Message to Operators of Federal Signal Light/Sound Systems” (part no. 256B691) (Figure 6.2). The operator must read and understand the safety

instructions and keep the card in the vehicle for reference.

Applying the Siren Safety Labels in the Vehicle

The e-Q2B Siren System kit includes a sheet of two labels with siren safety messages (part no. 1612339) (Figure 6.2). These labels must be installed in the vehicle in which the system is installed. Place these

labels in areas that are clearly visible to operators and passengers. Do not adhere the labels to locations that would impair the driver’s ability to operate the vehicle. Never install the labels in areas where air bags may deploy.
