labeled with circuit number and function. These labels shall match the “as built” wiring schematic included<br />
with the vehicle(s) at time of delivery. It is preferred that this panel be mounted on or near the bulkhead of<br />
the patient compartment. It must have a closed, locking, well ventilated cabinet. Electrical cabinets which are<br />
accessed through exterior ambulance doors are not acceptable due to the possibility of the introduction of<br />
dirt, moisture, or other undesirable and potentially damaging agents. All circuit breakers, relays, flashers and<br />
diodes shall be mounted on this panel and be easily accessible.<br />

Wiring Criteria (2)<br />
Adjacent to the main power distribution board there shall be the electronic control module. This module shall<br />
include four (4) etched trace "printed" circuits connected to the total electrical system by three (3) computer<br />
type cables. This module shall direct low voltage switch commands from the front and rear control panels to<br />
the relays on the main power distribution board. This module shall include a five-minute delay timer circuit<br />
for patient compartment dome lights to function as checkout lights. Opening the rear or curbside doors with<br />
the battery switch off shall activate this circuit. After five minutes the circuit shall automatically turn off the<br />
dome lights. Cycling the left dome circuit switch will reactivate the circuit. This module shall be capable of an<br />
upgrade to include, if specified, an automatic sequencer circuit for emergency lighting and/or a load manager<br />
circuit to automatically "unload" non-critical lighting in the event of battery or charging system problems.<br />
There shall be spare jumper cards supplied with the vehicle for the logic board; one (1) each for the fiveminute<br />
timer circuit and the sequencer/load manager circuits, if specified.<br />
A six-inch service loop of wire or harness shall be provided at all electrical components, terminals, and<br />
connection points. Circuit breakers shall be of the automatic reset type and designed specifically for each<br />
circuit. One spare 15-ampere circuit breaker shall be provided for future use. All connections and terminals<br />
provided shall comply with SAE J163, or J561 or J928 as applicable.<br />
The main wiring harness for the module body shall be installed down the center of the patient compartment<br />
ceiling. Each electrical circuit shall branch from the master harness as needed. There shall be no splices in this<br />
harness. Each circuit wire shall run from the distribution panel to the fixture without a break or connection.<br />
An access panel shall run the entire length of the center of the ceiling to simplify access to the "master" wiring<br />
harness. A padded upholstery type material to prevent head injuries shall cover the access panel. This panel<br />
shall be fastened to the ceiling with collared trim screws. Wiring runs accessed by removing interior cabinets<br />
or portions thereof are not acceptable to the Purchaser.<br />
