Pre - Alarm: alternating red flashing LED's; Full Alarm: dual flashing red LED's and a flashing <br />PASS icon; Low Battery: red flashing LED's; Normal System Operation: flashing green LED. <br />The console shall contain a photo sensing diode to dim and brighten the HUD as the environment <br />changes. The console shall contain push buttons for user interface. The push buttons shall be <br />designed to minimize accidental activation. A yellow color -coded push button shall permit <br />system reset. A red color -coded push button shall permit manual activation of the full alarm <br />mode. <br />CONFIRM EXCEPTION <br />7) Rapid Intervention Connection <br />The SCBA shall incorporate a RIC /UAC fitting to be compliant with the 2013 edition of the <br />NFPA 1981 Self- Contained Breathing Apparatus standard. The RIC/UAC shall be an integral <br />part of the high - pressure hose that attaches the cylinder valve to the first stage pressure reducer. <br />The RIC/UAC inlet connect ion shall be within 4" (4- inches) of the tip of the CGA threads of the <br />cylinder valve. The RIC /UAC shall consist of a connection for attaching a high - pressure air <br />source and a self - resetting relief valve allowing a higher pressure than that of the SCBA to be <br />attached to the SCBA. The RIC/UAC shall have a check valve to prevent the loss of air when <br />the high - pressure air source has been disconnected. <br />CONFIRM EXCEPTION <br />8) Cylinder <br />The cylinder threads shall be straight with an O -ring or quad -ring gasket type seal. The cylinder <br />valve shall be a "fail open" type, constructed of forged aluminum and designed such that no stem <br />packing or packing gland nuts are required. It shall contain an upper and lower seat such that the <br />pressure will seal the stem on the upperseat, thus preventing leakage past the stem. No <br />adjustment shall be necessary during the life of the valve. If the SCBA is equipped with a CGA <br />cylinder connection, the cylinder valve outlet shall be a modification of the Compressed Gas <br />Association (CGA) standard threaded connection number CGA 347 for 5500 systems. <br />Each cylinder valve shall consist of the following: 1) a hand activated valve mechanism with a <br />spring - loaded, positive action, ratchet type safety lock and lock -out release for selecting "lock <br />open service" or "non -lock open service "; 2) an upstream connected frangible disc safety relief <br />device; 3) a dual reading pressure gauge indicating cylinder pressure at all times; 4) an <br />elastomeric bumper; 5) an angled outlet. Each cylinder and valve assembly shall be equipped <br />with a hanger bracket for positive locking attachment of the assembly to the backframe. The <br />SCBA shall maintain all NIOSH and NFPA standards with any of the following types of <br />cylinders listed as provided by the SCBA manufacturer. <br />Carbon - Wrapped <br />The cylinder shall be manufactured in accordance with DOT specifications and meet the <br />Transport Canada requirements with working pressures of 5500 psig. The cylinder shall be <br />lightweight, composite type cylinder consisting of an aluminum alloy inner shell, with a total <br />overwrap of carbon fiber, fiberglass and an epoxy resin. The cylinder shall be available in 45- <br />minute duration based on the NIOSH breathing rate of 40 liters per minute (lpm). <br />5 <br />
