Production Specification

SVI #774 Page 110 of 126 April 19, 2010

A voltmeter shall be mounted on the driver’s instrument panel to allow direct observation of the system voltage.

Electromagnetic Interference

Electromagnetic interference suppression shall be provided, as required, to satisfy the radiation limits specified in SAE

J551/1, Performance Levels and Methods of Measurement of Electromagnetic Compatibility of Vehicles, Boats (up to 15

m), and Machines (16.6 Hz to 18 GHz).

Wiring Diagram

A complete electrical wiring schematic of actual system shall be provided with finished apparatus. Similar or generic type

electrical schematics shall NOT BE ACCEPTABLE.

Low Voltage Electrical System Performance Test

A low voltage electrical system test certification shall be provided with delivered apparatus.

12 VOLT MULTIPLEX CONTROL CENTER

The apparatus shall have a multiplexed 12 volt electrical system that will provide complete diagnostic capability. The

system shall have the capability of delivering multiple signals via a CAN bus, utilizing specifications set forth by SAE

J1939. The system shall be node based to maximize stability so that failure of one node does not affect the operation of

the other nodes. The system shall use shielded twisted-pair wire for transmission of system function signals. The

shielded wire shall provide protection against EMI and RFI noise interruptions.

The multiplex system shall be responsible for providing power management functions as well as load shedding. The

warning light system shall be controlled by the multiplex system. The system shall be capable of displaying text and/or

graphic messages on a display module. The system shall be based on solid-state technology and shall include self-

contained diagnostic indicators.

BATTERY SYSTEM

The battery connectors shall be heavy duty type with cables terminating in heat shrink loom. Heavy duty battery cables

shall provide maximum power to the electrical system. Where required, the cables shall be shielded from exhaust tubing

and the muffler. Large rubber grommets shall be provided where cables enter the battery compartment.

Batteries shall be of the high-cycle type. With the engine off, the battery system shall be able to provide the minimum

continuous electrical load for 10 minutes without discharging more than 50 percent of the reserve capacity and then to

restart the engine. The battery system cold cranking amps (CCA) rating shall meet or exceed the minimum CCA

recommendations of the engine manufacturer. The batteries shall be mounted to prevent movement during fire apparatus

operation and shall be protected against accumulations of road spray, snow, and road debris. The batteries shall be

readily accessible for examination, testing, and maintenance.

A means shall be provided for jump-starting the engine if the batteries are not accessible without lifting the cab of a tilt-cab

apparatus.

Where an enclosed battery compartment is provided, it shall be ventilated to the exterior to prevent the buildup of heat

and explosive fumes. The batteries shall be protected against vibration and temperatures that exceed the battery

manufacturer’s recommendation.

A master load disconnect switch shall be provided between the starter solenoid(s) and the remainder of the electrical

loads on the apparatus. The starter solenoids shall be connected directly to the batteries.
