KKK-A-1822 E
THE VEHICLE'S GENERATING SYSTEM CAPACITY. All electrical system components
and wiring shall be readily accessible through access panels for checking and maintenance. All
switches, indicators, and controls shall be located and installed in a manner that facilitates easy
removal and servicing. All exterior housings of lamps, switches, electronic devices, connectors,
and fixtures shall be corrosion resistant and weatherproofed.
Electrical fixtures attached to the sides of the ambulance below the 191 cm (75 in.) level shall be
near flush mounted and not protrude more than 51 mm (2 in.), except for such items as spotlights
and ventilators. All electrical devices and equipment installed, including the electromagnetic
coils of high current solenoids, and relays etc, which produce RFI, shall include filters, suppressers,
or shielding to prevent electromagnetic radiation and the resultant interference to radios and
other electronic equipment (see 3.7.12). Vehicles equipped with electronic engine controls shall
be immune from interference caused by radio transmissions.
WARNING: ELECTRICAL LOADS SHALL BE MINIMIZED. ADDITIONAL
ELECTRICAL LOADS ABOVE THOSE REQUIRED BY THIS
SPECIFICATION SHOULD BE AVOIDED BECAUSE HEAVY LOADS
CAUSE ALTERNATOR AND BATTERY FAILURES. FAILURE OF
THESE COMPONENTS WILL LIKELY RESULT IN THE AMBULANCE
NOT BEING ABLE TO COMPLETE ITS MISSION.
The electrical system shall include patient compartment outlets for 12 volt power (see
3.7.7.3) for medical equipment. A driver compartment console-mounted "module
disconnect switch or device" (see 3.7.7.4) shall be provided which controls the equip-
ment as defined in Figure 5, page 87.
3.7.1.1 WARNING INDICATORS.
The electrical system shall incorporate a warning light panel located in the driver's
compartment. It shall provide indicator lights for showing: open patient compartment
entry door(s) (see 3.10.8); open equipment compartment door(s); and when batteries are
turned on by the battery disconnect switch (when furnished) (see 3.7.7). The "Door
Open" warning lights shall be red, flash, and approximately 13 mm (1/2 in.) in diameter,
or equal, in area. The battery indicator light shall be green with a lens approximately 13
mm (1/2 in.) in diameter, or equal, in area. Electronic displays that are visible in all ambient
light, that projects narrative information may be used in lieu of discrete, colored, indicator/
warning lights provided the projected message is at least as visible as the basic required
warning light and complies with FMVSS 101 for displays.. The use of "high intensity"
LEDs in lieu of the 13 mm warning light is acceptable. Warning indicators shall be identified
and marked per 3.7.11.
3.7.2
WIRING INSTALLATION.
The ambulance body and accessory electrical equipment shall be served by circuit(s) separate
and distinct from vehicle chassis circuits. All wiring provided by the ambulance manufacturer
shall be copper and conform to all the SAE J1292 requirements and shall have type SXL or
GXL high temperature cross linked polyethylene, or better, insulation conforming to SAE
J1127 and J1128. The use of multi conductor or ribbon cables are permitted provided they are
not exposed to under hood or under vehicle temperatures/conditions. The wiring shall be
