each emergency light shall flash on/off 75 to 125 times per minute. Each light shall <br />have a minimum of 20 square inches of illuminated viewing area. The flash pattern <br />for the warning lights on this vehicle shall be as described in KKK-A-1822F, Section <br />3.8.2.1, Table 1. Compliance with this specification shall not be compromised in <br />order to maintain a high level of conspicuity for 360-degrees around the vehicle. <br />Oft, <br />5.9 PARK OVERRIDE WITH AUTOMATIC RESET CANCEL SWITCH <br />All forward facing clear lights shall be shut off when the vehicle is placed into park or <br />neutral. An override switch shall be provided in the front switch console. <br />Y_�,N <br />5.9.1 BRAKE OVERRIDE <br />Two [2] rear mid -height lights shall be wired to brakes. The brakes shall override the <br />flashers. <br />Y_N <br />6.0 CONSTRUCTION CHARACTERISTICS <br />The body shall be 170" long and 93.5" high. All body panels, structures, and <br />extrusions shall be fabricated of aluminum using alloys consistent with the load <br />requirements of the vehicle. Unitized body construction will be accomplished by MIG <br />welding all sheets, radius extrusions, corners, structural members together. All body <br />surface aluminum side panels and roof panels shall be intermittently Heli arc welded <br />to the body frame support members in such a manner as to provide maximum <br />strength and durability without causing heat warp. All exterior metal -to -metal body <br />seams or the area of attachment of one aluminum panel to another shall be Heli arc <br />welded. All such welds shall be ground smooth for proper paint adhesion and <br />appearance. The body structure shall be built and warranted by the vehicle <br />manufacturer. The vehicle must additionally meet or exceed AMD Standard 001, <br />Static Load Test for Ambulance Body Structure. <br />Y N <br />6.1 CERTIFIED WELDING PERSONNEL <br />To assure that the specified vehicle meets the letter, as well as the intent of the <br />Specification, the welding of body structure, chassis attachment points, doors, any <br />aluminum or stainless steel components or attachments shall be performed by or <br />directly supervised by personnel Certified by the American Standard Welding <br />Association (ASWA). Those individuals shall have proof of current certification and <br />shall make such proof available to the department upon reasonable demand. <br />Y N <br />6.2 CORNER EXTRUSIONS <br />To ensure weight support and structure durability in the event of an accident or <br />impact the utmost strength in corner posts must be used. A radius arched aluminum <br />extrusion is required. The extrusion shall include a full-length reinforcing member <br />that extends from the crest of the curvature to the focal point of the outer arch. The <br />continuous gusset must be extruded into the corner radius. Corner posts that are a <br />part of the exterior body skin are not recommended as they may pull away at the <br />point of impact. The extrusions must have a minimum strength of 29,000 psi. <br />Y4_N <br />
