Specifications

Proposal Number PSDF #P09-0004
furnished for the cab.
EMI/RFI PROTECTION
The apparatus shall incorporate the latest designs in the electrical system with state of the art components to
insure that radiated and conducted electromagnetic interference (EMI) and radio frequency interference
(RFI) emissions are suppressed at the source.
The apparatus proposed shall have the ability to operate in the environment typically found in fire ground
operations with no adverse effects from EMI/RFI.
EMI/RFI susceptibility is controlled by utilizing components that are fully protected and wiring that utilizes
shielding and loop back grounds where required. The apparatus shall be bonded through wire braided
ground straps. Relays and solenoids that are suspect to generating spurious electromagnetic radiation are
diode protected to prevent transient voltage spikes.
In order to fully prevent the radio frequency interference the purchaser shall be requested to provide a listing
of the type, power output, and frequencies of all radio and bio medical equipment that is proposed to be used
on the apparatus.
BATTERY BOX TRAY
The battery box trays shall be painted steel. The battery hold down brackets hardware shall be black powder
coated to resist corrosion.
BATTERY BOX COVER
To reduce road spray a sand paper abraded finish aluminum cover shall be installed on each battery box.
BATTERY BANK
A single battery system shall be provided, utilizing six (6) high cycle type Group 31 batteries.
This system shall be capable of engine start after sustaining a continuous 150 amp load for 10 minutes with
the engine off (NFPA-1901).
A battery disconnect switch (Rated at not less than 450 amps continuous) shall be used to activate the system
and provide power to the power panel. A green pilot light shall illuminate to indicate that the battery bank is
activated.
All battery wiring shall be "GXL" battery cable capable of handling 125% of the actual load. It shall be run
through a heat resistant flexible nylon "HTZL" loom rated at a minimum of 300 degrees Fahrenheit. All
cable connections shall be machine crimped and soldered.
STARTING CIRCUIT
One (1) engine start button is to be located on the lower right dash panel. It shall be wired to heavy duty
solenoid rated at not less than 1100 amps. The battery indicator light is to be located directly above the start
button to indicate that the battery bank is on.
