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.

Listed below are some other important safety instructions and precautions you should

follow.

Before Installation or Service

Qualiﬁcations

• To properly install or service this equipment, you must have a good understanding

of automotive mechanical and electrical procedures and systems, along with

proﬁciency in the installation and service of safety warning equipment. Always

refer to the vehicle’s service manuals when performing equipment installations on

a vehicle.

Light Hazards

• To be an eective 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.

• Do not install the light system in an area that would block, impair, or blind the

driver’s vision. Ensure that the light system is mounted in a position that is outside

the driver’s ﬁeld of vision so the driver can safely operate the vehicle.

• Federal Signal power supplies and light heads are designed to work together as

a system. Combining light heads and a power supply from dierent manufacturers

may reduce the warning eectiveness of the lighting system and may damage the

components. You should verify or test your combination to ensure that the system

works together and meets federal, state, and local standards or guidelines.

Electrical Hazards

• The lighting system components, especially light bulbs, strobe tubes, LEDs, and

the outer housing, get hot during operation. Disconnect power to the system and

allow the system to cool before handling any components.

• A light system is a high current system. In order for the system to function

properly, a separate negative (–) connection and positive (+) connection must

be made. All negative connections should be connected to the negative battery

Installation, Operation, and Service Manual

Safety Messages for Installers and Service Personnel

terminal, and a suitable fuse should be installed on the positive battery terminal

connection as close to the battery as possible. Ensure that all wires and fuses are

rated to handle the device and system amperage requirements.

• Never attempt to install aftermarket equipment that connects to the vehicle

wiring without reviewing a vehicle wiring diagram available from the vehicle

manufacturer. Ensure that your installation will not aect vehicle operation or

mandated safety functions or circuits. Check the vehicle for proper operation after

installation.

• Do not mount a radio antenna within 18 inches (45.7 cm) of the lighting system.

Placing the antenna too close to the lighting system could cause the lighting

system to malfunction or be damaged by strong radio ﬁelds. Mounting the

antenna too close to the lighting system may also cause the radio noise emitted

from the lighting system to interfere with the reception of the radio transmitter and

reduce radio reception.

• Do not attempt to wash any unsealed electrical device while it is connected to its

power source.

• 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

veriﬁed that no shorts exist. If the wiring is shorted to the vehicle body or frame,

high current conductors can cause hazardous sparks, resulting in electrical ﬁres or

ﬂying molten metal.

• DO NOT install equipment or route wiring (or the plug-in 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.

• Before mounting any components, check the manual to be sure that the

component you are installing is suitable for use in that area of the vehicle. Many

components are not suitable for use in the engine compartment or other extreme

environmental exposure areas.

• When drilling into a vehicle structure, ensure that both sides of the surface are

clear of anything that could be damaged. Remove all burrs from drilled holes. To

prevent electrical shorts, grommet all drilled holes through which wiring passes.

Ensure that the mounting screws do not cause electrical or mechanical damage to

the vehicle.

• Refer to the manual packed with the lighting system for proper electrical

connections, additional precautions,and information.

8CN SignalMaster™

Federal Signal www.fedsig.com

An Overview of the CN SignalMaster

The CN SignalMaster™is a single-level LED light bar with ROC™(Reliable On-Board

Circuitry) and Solaris®LED technologies. ROC eliminates approximately 85 percent of

potential failure points by incorporating a printed circuit board (PCB) in one assembly

to substantially reduce the number of electrical connections. Solaris S2 LED modules

use oset, complex reﬂector surfaces for accurate beam shaping and the highest

optical eciency. The CN SignalMaster is available in eight-head and four-head

models for both front and rear. It is also available in a rear only, split eight-head model,

with a 12-foot cable joining two four-head units (CNSM2X4R).

LED Lights, Colors, and Flash Patterns

The light bar’s internal microprocessor supplies three priority operational modes

and a library of 27 ﬂash patterns. To increase the safety of ocers, pedestrians, and

motorists, the light bar has standard dimming and intersection warning. Multi-color

heads are available with up to three dierent colored LEDs, eliminating the loss of

primary warning colors in takedown and directional warning positions. Individual

CN SignalMaster lightheads can ﬂash between red, blue, amber, or white. The light

bar operates at a nominal input of 13.6 Vdc (11 Vdc minimum) and an operating

temperature range of –30°C to +65°C.

The functions of the SignalMaster are controlled through the CAT5 serial

communication cable. The cable connects to either a compatible Federal Signal

Serial control head or a Federal Signal Serial Interface Module (P/N 8583446). An

internal PCB assembly within the light bar decodes the control data and performs the

requested function. With the Serial Interface Module, the light bar can be activated by

Federal Signal light bar controllers, SignalMaster controllers, and/or individual low-

current switches.

The housing is an anodized aluminum extrusion. The light bar has 15-foot power and

ground cables and a 25-foot serial cable. Universal mounting hardware is supplied;

vehicle-speciﬁc mounting hardware is also available separately.

Installation, Operation, and Service Manual

Federal Signal www.fedsig.com

INSTALLATION PRECAUTIONS: The warning system and/or two-way radio

system may operate improperly if a two-way radio antenna is installed on or

within 18 inches of the light bar. Before permanently installing the light bar or

a two-way radio antenna, test the warning system and two-way radio system.

Some installations may require the relocation of the two-way radio antenna

to the trunk or fender. DO NOT drill holes in the light bar or install auxiliary

devices on the light bar, or the warning system may fail.

Before proceeding, ensure that the light bar has been installed inside the vehicle in

accordance with the instructions included with the mounting kit.

NOTE: The DIP switch on the light bar’s control PCB provides three selectable

options. To change DIP switch selections, refer to “Setting Conﬁguration Options” on

page 13.

The CN SignalMaster™is completely wired at the factory and does not require any

additional internal wiring. Two 16AWG power conductors (red and black) and the

CAT5 communication cable exit the light bar. The conductors necessary to control the

light bar are contained in the CAT5 cable, which connects to a compatible Federal

Signal control head or to the Serial Interface Module.
