Specifications

44 of 104
12-volt 60-amp ignition switched power
12-volt 60-amp direct battery power
There shall also be a 12-volt 100-amp ground stud located in or adjacent to the power distribution
center.
ENHANCED SOFTWARE Bidder Complies: Yes ( ) No ( )
The solid-state control system shall include the following software enhancements:
All perimeter lights and scene lights (where applicable) shall be deactivated when the parking brake is
released.
Cab and crew cab dome lights shall remain on for ten (10) seconds for improved visibility after the
doors close. The dome lights shall dim after ten (10) seconds or immediately if the vehicle is put into
gear.
Cab and crew cab perimeter lights shall remain on for ten (10) seconds for improved visibility after the
doors close. The dome lights shall dim after ten (10) seconds or immediately if the vehicle is put into
gear.
EMI/RFI PROTECTION Bidder Complies: Yes ( ) No ( )
To prevent erroneous signals from crosstalk contamination and interference, the electrical system shall
meet, at a minimum, SAE J551/2, thus reducing undesired electromagnetic and radio frequency
emissions. An advanced electrical system shall be used to ensure radiated and conducted
electromagnetic interference (EMI) or radio frequency interference (RFI) emissions are suppressed at
their source.
The apparatus shall have the ability to operate in the electromagnetic environment typically found in
fire ground operations to ensure clean operations. The electrical system shall meet, without
exceptions, electromagnetic susceptibility conforming to SAE J1113/25 Region 1, Class C EMR for
10KHz-1GHz to 100 Volts/Meter. The vehicle OEM, upon request, shall provide EMC testing reports
from testing conducted on an entire apparatus and shall certify that the vehicle meets SAE J551/2 and
SAE J1113/25 Region 1, Class C EMR for 10KHz-1GHz to 100 Volts/Meter requirements. Component
and partial (incomplete) vehicle testing is not adequate as overall vehicle design can impact test results
and thus is not acceptable by itself.
EMI/RFI susceptibility shall be controlled by applying appropriate circuit designs and shielding. The
electrical system shall be designed for full compatibility with low-level control signals and high-powered
two-way radio communication systems. Harness and cable routing shall be given careful attention to
minimize the potential for conducting and radiated EMI/RFI susceptibility.
ELECTRICAL HARNESSING INSTALLATION Bidder Complies: Yes ( ) No ( )
To ensure rugged dependability, all 12-volt wiring harnesses installed by the apparatus manufacturer
shall conform to the following specifications:
SAE J1128 - Low tension primary cable
SAE J1292 - Automobile, truck, truck-tractor, trailer and motor coach wiring
SAE J163 - Low tension wiring and cable terminals and splice clips
SAE J2202 - Heavy duty wiring systems for on-highway trucks
NFPA 1901 - Standard for automotive fire apparatus
FMVSS 302 - Flammability of interior materials for passenger cars, multipurpose passenger vehicles,
trucks and buses
SAE J1939 - Serial communications protocol
