3.22 Wiring Criteria All wiring devices, outlets, etc., except circuit breakers, and switches shall be rated to carry at least 125% of the maximum ampere load for which the circuit is protected. There shall be a main power distribution board located within the ambulance. This panel shall incorporate an etched -trace "printed" circuit board with plug in style relays and circuit breakers. The board shall be a polyclad layered glass epoxy with a NEMA grade rating of FR -4. The board shall be rated to withstand the MIL - STD -810C Corrosion test and the MIL - STD -5511 OD Thermo Shock test. The panel shall incorporate LED lights indicating relay drive circuit operation. These LED's are labeled to indicate the circuit that is energized. This board shall be mounted to a .125" aluminum panel that shall be attached to the bulkhead in a manner to allow easy removal. All circuits in the panel shall be permanently labeled with circuit number and function. These labels shall match the wiring schematic included with the vehicle(s) at time of delivery. It is preferred that this panel be mounted on or near the bulkhead of the patient compartment in a closed, locking, well ventilated cabinet. All circuit breakers, relays, flashers and diodes shall be mounted on this panel and be easily accessible. NO EXCEPTIONS Does your bid comply? Yes No Adjacent to the main power distribution board there shall be the electronic control module. This module shall include four (4) etched trace "printed" circuits connected to the total electrical system by three (3) computer type cables. This module shall direct low voltage switch commands from the front and rear control panels to the relays on the main power distribution board. This module shall include a five - minute delay timer circuit for patient compartment dome lights to function as checkout lights. Opening the rear or curbside door with the battery switch off shall activate this circuit. After five minutes the circuit shall automatically turn off the dome lights. Cycling the left dome circuit switch will reactivate the circuit. This module shall be capable of an upgrade to include, if specified, an automatic sequencer circuit for emergency lighting and /or a load manager circuit to automatically "unload" non - critical lighting in the event of battery or charging system problems. There shall be spare jumper cards supplied with the vehicle for the logic board; one (1) each for the five - minute timer circuit and the sequencer /load manager circuits, if specified. NO EXCEPTIONS Does your bid comply? Yes No - A six -inch service loop of wire or harness shall be provided at all electrical components, terminals, and connection points. Circuit breakers shall be of the automatic reset type and designed specifically for each circuit. One spare 15- ampere circuit breaker shall be provided for future use. A Whelen Model AF6016A Dual Mode solid -state electronic flasher shall be heat sink mounted to the panel for control of the flashing warning light system. Low - voltage switches through the electronic control module shall control this flasher. All connections and terminals provided shall comply with SAE J163, or J561 or J928 as applicable. Does your bid comply? Yes---,.,/No The main wiring harness for the module body shall be installed down the center of the patient compartment ceiling. Each electrical circuit shall branch from the master harness as needed. There shall be no splices in this harness. Each circuit wire shall run from the distribution panel to the fixture without a break or connection. An access panel shall run the entire length of the center of the ceiling to simplify access to the "master" wiring harness. A padded upholstery type material to prevent head injuries shall cover the access panel. This panel shall be fastened to the ceiling with collared trim screws. Does your bid comply? Yes L./ No Attachl4nt number 1 F -5 Page 113
