F I R S T -STAGE REGULATOR

The first-stage regulator is housed and protected within the backpack assembly. It connects to the air cylinder valve using a high pressure hose and a large, easy-to-grip stainless steel hand wheel. The stainless steel ghand wheel provides a positive connection reducing the risk of cross threading or thread damage. The first stage regulator lowers air cylinder pressure to approximately 115 psi, which is supplied to the second stage regulator via the intermediate pressure hose A relief valvevia the intermediate pressure hose. A relief valve activates to protect the system should the regulator pressure exceed 200 to 225 psi.

A hi h ti f th HUD t dA high-pressure connection for the HUD transducer, UAC, and the remote Pressure Gauge/PASS Alarm on the right shoulder are all housed and protected within the backpack assembly.

LOW AIR ALARM

The integrated low air warning alarm emits an audible-warbling whistle when the air cylinder pressure reaches 1035 to 1215 psi. (23 to 27 percent of the rated capacity

f th i li d ) Th l i i hi tl ill tof the air cylinder) The low air-warning whistle will operate until air cylinder pressure drops below 200 psi. The whistle is located in the upper left corner of the backpack and is protected by the thermal and impact resistant enclosure.

AIR PRESSURE GAUGE/PASS ALARM

A high pressure air hose is routed over the right shoulder strap and attach to the Air Pressure Gauge/PASS Alarm assembly. The gauge is luminescent for low light viewing and indicates the quantity of air remaining in the air cylinder once the air

li d l i d Ai i ill t t d f f llcylinder valve is opened. Air pressure is illustrated from full “F” to empty “E” using quarter increments “¼ ½ ¾” similar to a fuel gauge on a vehicle.

Opening the air cylinder valve arms the PASS device as airOpening the air cylinder valve arms the PASS device as air pressurizes the system. An ascending tone and alternating green flashing LED lights indicate activation. The PASS device can be manually triggered to full alert by depressing and holding the red alarm button for 1 to 2 seconds.

Once the PASS reaches full alert, it can only be reset to normal operation by two slow and deliberate clicks of the yellow reset button the side of the housing Reset is indicated by abutton the side of the housing. Reset is indicated by a descending tone. Two additional slow and deliberate clicks of the yellow reset button will shut-off the PASS device if the air has been bleed from the system.

AIR PRESSURE GAUGE/PASS ALARM

Lack of movement will start the staged alarm in approximately 20 seconds. The LED lights will alternate flashing green and red. The alarm will increase in volume approximately every 5 seconds until full alert at 30 to 35 seconds. In full alert, the LED lights flash red and the alarm tones alternate between theLED lights flash red and the alarm tones alternate between the front and rear mounted piezo speakers.

The PASS device is powered by the 4 C-cell batteries in the backpack. An amber LED in the PASS device acts as thebackpack. An amber LED in the PASS device acts as the battery status indicator for the front of the SCBA.

SECOND STAGE REGULATOR

The second stage regulator attaches to the facepiece using the Air Klic system. This mechanism automatically locks y ywhen the regulator is pushed into the Air Klic on the facepiece. The second stage regulator is activated by the First Breath On mechanism or by the manual override button on the front of the regulator. To disengage the regulator from the facepiece two steps need to be followed Firstfrom the facepiece two steps need to be followed. First, press the black rectangular shut-off button at the twelve o’clock position on the regulator to stop the air supply. Second, depress both opposing gray release buttons at the twelve and six o’clock positions and pull the regulator from the facepiece.

SECOND STAGE REGULATOR

The second stage regulator is capable of supplying the user in excess 350 liters per minute of breathing air. The large red p g gknob on the regulator controls the adjustable bypass valve. Turning the bypass valve knob counterclockwise provides a constant flow of breathing air. The bypass valve is intended for emergency use only to supply breathing air should regulator failure occur The bypass valve is capable forregulator failure occur. The bypass valve is capable for supplying a maximum of 130 liters per minute of breathing air. When not in use the regulator should be stored in the regulator belt clip located on the left waist strap. The second stage regulator supplies breathing air via an intermediate pressure hose with a quick connect fitting.

HEADS-UP DISPLAY (HUD)

The HUD is mounted as part of the second stage regulator. When the second stage regulator is attached to the facepiece, the HUD display is visible through opening in the facepiece nozzle cover. When the air cylinder valve is opened, the HUD will activate automatically, and indicate the pressure available in the air cylinder. The display consists of four green LED’s indicating from right to left, Full, ¾, ½, andfour green LED s indicating from right to left, Full, ¾, ½, and ¼. A cylinder at 4500 psi will illuminate all 4 green LED’s. As the pressure in the air cylinder decreases, the LED’s turn off one at a time for each ¼ (25%) drop in air cylinder pressure.

When the pressure drops below 50% of air cylinder capacity, the LED representing ½ cylinder capacity starts to blink. The blinking will continue for approximately 20 seconds before returning to constant illumination.

HEADS-UP DISPLAY (HUD)

When the pressure drops below 25% of air cylinder capacity, the LED representing ¼ cylinder capacity changes color to red and starts to blink. A corresponding red LED on the front of the HUD will blink warning others of the users low air supply. When the pressure drops to 10% of air cylinder capacity, the LED representing ¼ cylinder capacity blinks noticeably faster. The LED on the front will also increase isnoticeably faster. The LED on the front will also increase is blinking rate. The increased rate of blinking will continue until air cylinder pressure drops below 200 psi at which time the HUD will shut-off.

A photodiode on the top of the HUD adjusts the green LED intensity so they are not a distraction to the user.

FACEPIECE

The Warrior SCBA 20/20 facepiece is made of butyl rubber which enables it to pass the CBRN certification test. It has a wide lip sealing surface and four point adjustable head net harness. The

l b t l i t t d ith b ipoly-carbonate lens is treated with an abrasion resistant coating on the outside, and an anti–fog solution on the inside.

Breathing air from the second stage regulator entersBreathing air from the second stage regulator enters the facepiece and is directed onto the poly-carbonate lens. The cool air allows the lens to withstand the heat and flame impingement tests required for NFPA compliance. The integrated nose

ll f h i t t th d thcup allows fresh air to enter the nose and mouth while capturing exhaled air and routing it through the exhalation valve, minimizing CO2 retention in the facepiece and reducing lens fogging. The nose cup also houses the speaking diaphragm and p g p gmicrophone for the Voice Projection Unit.

The air klic port is threaded into the housing by a ratchet mechanism to prevent leakage and provide a secure mount for the second stage regulator.

The 20/20 facepiece should not be stored in direct sunlight. Sunlight has a degrading effect on butyl rubber and nomex materials.

VOICE PROJECTION UNIT (VPU)

The Voice Projection Unit is designed to facilitate verbal communication while wearing a facepiece. The unit provides the wearer a choice of brief or constant voice amplification by pushing the power button on top of the VPU. One depression of the power button activates the VPU for two seconds Twoof the power button activates the VPU for two seconds. Two consecutive pushes of the power button activates the VPU for continuous use.

A red LED light is visible to the user on the right side of the facepiece to indicate the unit is on An amber LED light willfacepiece to indicate the unit is on. An amber LED light will blink to warn the user of a low battery. The VPU is powered by three AAA batteries and

The VPU is powered by three AAA batteries and can be changed in the field by opening the battery compartment door at the front of the housing.

Two more consecutive pushes of the power button will turn th VPU ff Th VPU tt h t th i ht id f ththe VPU off. The VPU attaches to the right side of the facepiece using an alignment tab and a threaded knurled knob. Electrical contacts connect the VPU to the microphone located within the facepiece. The amplifier’s low attachment location minimizes obstruction of the wearer’s vision, and its ,ergonomic controls allow operation with a gloved hand.

INFORMATION LIGHTING

A LED informational lighting component has been added to the Warrior SCBA to allow the user and surrounding crew members to assess each unit’s status All lighting on the backpack assemblyassess each unit’s status. All lighting on the backpack assembly are located on the right and left side of the air cylinder. Lighting on the front of the SCBA is located on the second-stage regulator and PASS device.

Amber LED’s on the upper right rear of the backpack and the front PASS device blink once every 10 seconds to indicate a usable battery condition. Blinking every two seconds indicates a low battery condition If a low battery condition occurs during use anbattery condition. If a low battery condition occurs during use, an amber LED on the HUD will blink every second. The SCBA may continue to be used and the batteries shall be replaced before the next usage.

INFORMATION LIGHTING

A red LED above the battery status light will blink went the user’s remaining air supply has reached ¼. This will occur approximately at the same time the audible low air alarm isapproximately at the same time the audible low air alarm is activating. A corresponding red LED on the front of the HUD will blink warning others of the users low air supply.

T LED’ h id f th i li d tTwo LED’s, one on each side of the air cylinder act as a visual reference to the PASS device operation. During normal operation, alternating green LED’s will blink once every second. The LED lights will alternate blinking green and red as the PASS device begins its staged operation. At g g pfull alert, the red LED’s will blink once every second.

UNIVERSAL AIR CONNECTION (UAC)

The Warrior SCBA comes equipped with the Rapid Intervention Crew / Universal Air Connection (RIC UAC). Located on the lower left side of the backpack, the UACLocated on the lower left side of the backpack, the UAC has a dust cover that must be used at all times. Connection to the UAC via the mating fill coupling allows a one direction flow of air into the user’s air cylinder. A directional flow control piston is located in the quick di t li t t id t l i l A li fdisconnect coupling to prevent accidental air loss. A relief valve is designed to vent air to atmosphere if the fill pressure exceeds the air cylinder service pressure.

The UAC is intended for refilling of an air cylinder under an emergency situation. It must never be used as a Buddy Breathing device, for SCBA to SCBA filling, or as a continuous air supply.

EMERGENCY BREATHING SAFETY SYSTEM (EBSS)SAFETY SYSTEM (EBSS)

The Emergency Breathing Safety System is designed to allow connection to a supplied air line or another EBSS. It is intended to supply EMERGENCY AIR to a fire fighter who has become lost, trapped, or disoriented in an IDLH environment. The EBSS is located in a storage pouch on the wearers left hip and consists of apouch on the wearers left hip and consists of a 39 inch intermediate pressure hose and a “Y” block with a male and female quick connect.

Wh t SCBA’ t d i th E B thi S f t S t th i t f f iWhen two SCBA’s are connected using the Emergency Breathing Safety System there is no transfer of air. The SCBA with the higher intermediate pressure will automatically supply both SCBA’s until that air is exhausted. At that point air in the SCBA that had the lower intermediate pressure will supply air both SCBA’s. The users will have no way of knowing which air cylinder will be supplying the air initially unless they are monitoring theIr air cylinder pressure gauges. g y p g g

The acceptable range for setting intermediate pressure is 80 to 150 psi. This is set by the manufacturer and can only be adjusted by repair personnel. This pressure range is more than capable of maintaining positive pressure to the facepieces of both fire fighters.
