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 the sound of the siren or horn 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.
• Federal Signal siren amplier/relay modules 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
8PA300-CN Siren Amplier
Light Hazards
• To be an effective warning device, warning lights produce bright light that can be hazardous to your
eyesight when viewed at close range. Do not stare directly into the lighting product at a close range or
permanent damage to your eyesight may occur.
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/relay module 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
airbag 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 airbag.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be
recalibrated for proper airbag deployment.

CHAPTER 3
Connecting the PA300-CN System
Before permanently mounting the PA300-CN system, plan all wire routings and select the mounting
locations for the siren amplier/relay module and control pad. Also read and understand all instructions
included with related equipment before installing it.
Selecting Mounting Locations
When fastened to the back of the control pad, the mounting bracket covers the wiring connectors and a
supplemental control for the gain or volume of the radio rebroadcast feature. To facilitate the installation of
the PA300-CN system, select mounting locations for the control pad and the siren amplier/relay module
before permanently mounting them in the vehicle. After completing the wiring described in this chapter, refer
to the instructions for mounting the control pad and the siren amplier/relay module in Chapter 5 on page 33.
AIRBAG DEPLOYMENT—Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce the
effectiveness of the airbag or potentially dislodge the equipment, causing
serious injury or death.
SEAT REMOVAL PRECAUTION—If a vehicle seat is temporarily removed, verify
with the vehicle manufacturer if the seat needs to be recalibrated for proper
airbag deployment.
UNIT IS NOT WATERPROOF—The housing of the PA300-CN module is NOT
waterproof. The module must be mounted in a location that is sheltered from
falling rain, snow, standing water, etc.
For the control pad, 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

Preparing to Connect the PA300-CN System
The PA300-CN has the following types of Convergence Network connections via cables and locking
connectors included with the PA300-CN kit:
■ Three “plug and play” serial ports that communicate on the Federal Signal Convergence Network with
the control pad, compatible lightbars, and the Federal Signal Model 660100 Relay Module/Two-Channel
Flasher.
■ Speakers, radio rebroadcast, a park disable circuit, and a horn ring circuit (cable assembly P/N 1461907)
■Power wires for negative ground and positive 12 Vdc
■Connections on the back of the control pad for four active-low input circuits that activate when pulled to
ground.
For instructions on conguring the operation of the devices connected through the Convergence Network,
see the “Control Pad Conguration Software Manual", P/N 2562620.
To prepare the vehicle for the electrical installation of the PA300-CN:
1. Select jumper settings within siren amplier, which are accessible through an opening in the case, for
these options:
◆ GND or +12 V activation of the HORN RING transfer circuit (page 20)
◆ GND or +12 V activation of the PARK INPUT circuit (Page 23)
DRILLING PRECAUTIONS—When drilling holes, check the area into which you
are drilling to be sure that you do not damage vehicle components. 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.
2. After planning where to route the wires and cables for the PA300-CN 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 the holes. Apply silicone sealant where needed.
Connecting Serial Devices to the Convergence Network
There are three Convergence Network ports on the upper right corner of the PA300-CN siren amplier.
These ports connect Federal Signal serially-controlled devices through RS-485 communication cables.
Network devices include:
◆ The control pad. Use the 25-foot FS Convergence Network cable (P/N 1751357-02) to connect the
control pad to the siren amplier.
◆ Exterior-mounted, full-size lightbars, such as the Valor, Vision SLR, Arjent®S2, Legend®, and
Raydian® S2. Congurable options include ash patterns and functions, such as dimming,
takedowns, and alley lights.

Chapter 3: Connecting the PA300-CN System
17
PA300-CN Siren Amplier
◆ ILS System lightbars that include three models of single-level LED lightbars—Front ILS, Rear
Lower ILS, and Rear Upper ILS—that mount on the inside of a vehicle windshield. Congurable
options include ash patterns and functions, such as dimming, takedown lights, and alley lights.
Figure 3.3 shows the three network serial connections on the back of the siren amplier. Any one of the
connectors must be used for the control pad. For mounting instructions for the serial network devices,

The Model 660100 Relay Module/Two Channel Flasher is included with the Model 690200 PA300-CN
siren amplier. It controls up to four different devices of which two can be activated as a two-channel
asher. The Model 660100 uses less than 15 mA of power when connected to the vehicle battery with
the network disabled. When the network is enabled, an additional 25 mA is consumed from the network
power lines during standby. To draw no current, we recommend that the Model 660100 be powered
with an in-line switch capable of handling the total switch current of the active device.
Connect the serial cable included with the relay module to any one of the three serial connectors on the
front of the PA300-CN siren amplier (Figure 3.4). For more detailed instructions, refer to document
No. 2562431, “Model 6600100 RS485 Relay Module/Two-Channel Flasher."

Connections for One or Two Speakers (Cable Assembly P/N 1461907)
The PA300-CN is designed to operate to operate with one 11-ohm impedance speaker or two 11-ohm
impedance, low power (58 W) or high power (100 W), speakers connected in parallel and in phase.
WIRING PRECAUTION—Do not connect the brown zip cord wires to the
speaker. Failure to follow this precaution may damage the speaker system.
WIRING PRECAUTION—NEVER CONNECT the brown SPEAKER HIGH
POWER (100 W) wire and orange SPEAKER LOW POWER (58 W) wire
together to the speaker(s). Damage to the unit will occur if speaker wires
are improperly connected.
To connect one or two Federal Signal speakers:
1. Use 18 AWG wire to connect the two speaker leads marked “1” to the BLUE "Speaker Common"
lead from the cable assembly (P/N 1461907).
2. Use 18 AWG wire to connect the two speaker leads marked “2” to the BROWN "Speaker High
Power" or ORANGE "Speaker Low Power" lead from the cable assembly.
3. When nished, insulate the spliced leads with butt-spliced wire connectors. Fold and seal unused
leads.

Connections for Horn Ring Transfer (Cable Assembly P/N 1461907)
The default setting for the slide switch transfers the horn-ring activation of the siren amplier in
Slide Switch 2 and 3. In Slide Switch 2, a press of the horn button activates the Manual tone. In
Slide Switch 3, each press of the horn button cycles through siren functions. In addition, the default
conguration for Slide Switch 3 is Siren Dependent Enabled, which restricts siren activation to the
slide switch position the you select. For example, if you press a button that is assigned a siren tone,
the tone only activates when you place the slide switch in the position that is programmed to be Siren
Dependent Enabled.
To enable horn-ring control of siren tones, obtain a SPST relay of enough contact-current capacity to
activate the vehicle horn:
1. Cut the wire that connects the switch for the vehicle horn ring to the horn or horn relay (Figure
3.6).
2. Splice the WHITE/YELLOW wire from the cable assembly (P/N 1461907) to the horn ring side of
the wire that you cut in step 1. Extend wiring with an 18 AWG lead or thicker.
