DANGER!Sirens produce extremely loud emergency warning tones! Exposure to these tones without proper and adequate hearing protection,
could cause ear damage and/or hearing loss! The Occupational Safety & Health Administration (www.osha.gov) provides information necessary to
determine safe exposure times in Occupational Noise Exposure Section 1910.95. Until you have determined the safe exposure times for your
specific application, operators and anyone else in the immediate vicinity should be required to wear an approved hearing protection device.
FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!
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 he can operate
the system without taking his 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.
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.

Locate the PA adjustment potentiometer on the right side of the
CenCom module. Using a small, flat-blade screwdriver, set the
potentiometer to its middle position. With the CenCom™ system on,
activate the PTT (Push To Talk) feature on the optional microphone.
Adjust the potentiometer until a satisfactory PA volume level is achieved
using a normal speaking voice.
Radio Repeat Volume Adjustment
To Adjust the Radio Repeat Levels: Before placing this unit into service,
the Radio Repeat output volume must be adjusted to satisfactory
operating levels. To adjust this level, a small, flat-blade screwdriver is
needed. Locate the Radio Repeat adjustment potentiometer on the
right side of the CenCom module. Set the volume of the vehicle’s twoway radio to its normal operating level. Press the RAD button on the
control head to activate Radio Repeat. As incoming transmissions are
received, adjust the Radio Repeat potentiometer to set the desired
level. Turn the potentiometer clockwise to increase the level and
counter-clockwise to decrease the level.
Input Expansion Module (optional)
The optional input expansion module enables up to eight (8) non-CenCom
vehicle components and/or equipment to be integrated into the CemCom/
Cantrol network.
As shown in the tables below, connect the input wire of the desired device
to the appropriate wire. For example, if the device in question requires a
Positive input signal, that input wire would be connected to the BROWN
expansion module pigtail wire. In this example, that device would be
recognized as “INPUT 1” by the Cantrol system. However, if that device
requires a Negative input signal, that input wire would be connected to the
WHT/BRN expansion module pigtail wire. Note that this device would be
recognized as “INPUT 1” by the Cantrol system.
Amp/relay Module Fusing Information
CenCom Module Fuses
For ease of access, all of the amp/relay module fuses are accessible from
outside the case.
Input Expansion Table
Control Heads....
A wide variety of control heads are available for use with this system.
The specific function of any button, slide switch or rotary knob can be
customized via the CenCom configuration software program. The
following pages will present all of the available control heads and their
default operating configuration.
Isolated Relay (Outlet 8)
The position of the Output 8 fuse determines the function of the Brown,
Red and Orange wires. When the fuse is in Position 1, these wires act as
a Isolated 10 Amp Relay. When the fuse is in Position 2, the Brown and
Red wires act as Outlet #8. Refer to the schematic shown for the
electronic properties of this circuit.

LED Indicators
LED Indicators provide valuable information regarding the operational state of your CenCom system. There are 3 different sets of
LED’s for 3 different CenCom functions.
Traffic Advisor Indicators - These LEDs represent Traffic Advisor Output 1 (TA1) thru Traffic Advisor Output 8 (TA8). When a given
output is active or flashing, the state of its corresponding indicator will be one of the following, based on the condition of that particular
output:
On (steady) - Indicates the output is active and not flashing (normal).
On (flashing) - Indicates the output is active and flashing (normal).
Off - Indicates the output is shorted. Turn the CenCom system off, locate and remove the short. Restore power to the system
and activate the output to confirm its proper operation.
Output Indicators - These represent Outputs 1 thru 7. Each indicator is located directly adjacent to the fuse for that output.When a
given output is active, the state of its corresponding indicator will be one of the following, based on the condition of that particular
output:
On - Indicates the output is active (normal).
Off - Indicates the output is shorted. Turn the CenCom system off, locate and remove the short. Replace the fuse for that output
(with correct amperage rating) and restore power to the system. Activate the output to confirm its proper operation.
WC Diagnostic Indicators - These indicators provide the following diagnostic information about the CenCom system:
ERR (Error) LED
