ESB-CRG07 Compact Speaker Mounting Kit
•
Install the speaker(s) as far forward on the vehicle as possible, in a location that provides maximum
signaling effectiveness while minimizing 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 opera-
tion of airbag sensors.
•
Installation of two speakers requires that you wire the speakers in phase.
•
Never attempt to install aftermarket equipment, which connects to the vehicle wiring, without re-
viewing a vehicle wiring diagram, which is 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.
•
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.
After Installation
•
After installation, test the siren system and light system to ensure that it is operating properly.
•
Test all vehicle functions, including horn operation, vehicle safety functions and vehicle light sys-
tems, 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 operat-
ing personnel.
•
File these instructions in a safe place and refer to them when maintaining and/or reinstalling the
product.
Failure to follow all safety precautions and instructions may result in property damage, serious
injury, or death to you or others.
Before You Begin
IMPORTANT:
The ES100 and MS100 comply with the requirements of SAE J1849 EVS3 and CCR Title 13
Class A when they are used with Federal Signal Corporation electronic sirens.
The ES100 and MS100 are compact speakers intended to be mounted with the supplied mounting system.
If the ES100 and MS100 are installed with another mounting system, the safety and effectiveness of the
installation must be carefully evaluated.
Unpacking the Kit
After unpacking the kit, inspect it for damage that may have occurred in transit. If it has been damaged,
do not install it. File a claim immediately with the carrier, stating the extent of damage. Carefully check all
envelopes, shipping labels, and tags before removing or destroying them. Ensure that the parts listed in
Table 1 on page 3 are included in the package.
