XII. fUNCTIONAL TESTING TABLE
COMPONENT INSTRUCTIONS
FACEPIECE
1. Don and adjust the facepiece.
2. Block the AIR KLIC opening with the palm of your hand.
3. Inhale gently. The facepiece should collapse slightly and hold for a few seconds without
leaking.
4. Exhale with the AIR KLIC opening covered. The exhalation valve must not stick.
LEAK TEST
1. Push the shutoff button on the second stage regulator to stop the flow of air.
2. Open the cylinder valve to fully pressurize the regulators.
3. Close the cylinder valve.
4. Observe the gauge/alarm for 15 seconds. Significant needle movement indicates a
leak, and the SCBA should not be used.
AUDIBLE ALARM TEST
1. Open the cylinder valve to fully pressurize the SCBA.
2. Close the cylinder valve.
3. Press the shutoff button on the second stage regulator to stop the flow.
4. Slightly open and close the bypass valve to stop the gauge pointer at the 3/4 and 1/2
marks for 2 seconds.
5. Continue to open and close until the pointer moves slowly to the 1⁄3 full mark.
6. The audible alarm should begin when the gauge reaches approximately 1⁄3 full.
7. When the audible alarm begins, close the bypass valve.
8. The alarm should continue until the air is almost depleted.
9. Bleed all residual air.
10. Close the bypass valve.
HEADS-UP DISPLAY
1. Open the cylinder valve to fully pressurize the SCBA.
2. Close the cylinder valve.
3. Press the shutoff button on the second stage regulator to stop the flow.
4. Slightly open and close the bypass valve to stop the LED display at the 3⁄4 mark for 5
seconds.
5. Continue to open and close the bypass valve slowly until the HUD display reads 1⁄2
full.
6. Verify that the 50% warning is working correctly (the green LED representing 1⁄2
cylinder pressure should blink on and off for approximately 20 seconds, then stay
lighted continuously).
7. Continue to open and close the bypass valve slowly until the HUD display reads 1⁄3
full. The audible and visual alarm should begin when the display reaches approximately
1⁄3 full. Activation of the visual alarm (flashing red LED) portion of the display may or
may not coincide perfectly with the audible alarm (i.e., bell, whistle, etc.) on the SCBA.
8. When the audible alarm begins, close the bypass valve.
9. Both alarms should continue until the air is almost depleted.
10. Bleed all residual air.
11. Close the bypass valve.
SCBA FUNCTION TEST
1. Attach the CGA handwheel to a fully charged cylinder.
2. Close the second stage regulator bypass valve and depress the shutoff button.
3. Slowly open the cylinder valve.
4. Check that the cylinder valve gauge and chest-mounted gauge both read in the green
zone.
5. Attach the second stage regulator to the facepiece and inhale. The regulator should
deliver an acceptable flow of air without excessive effort, free flow, or fluttering.
6. Slowly open the bypass valve. A steady flow of air should enter the facepiece.
7. Depress the shutoff button. Air flow should stop.
8. Push the override button. A small burst of air should enter the facepiece and the
regulator should activate.
9. Close the cylinder valve and bleed all residual air.
