QUARTERLY SCBA PracticePart 1 MSA FIREHAWK HP 4500psi SCBA Developed by Jon Bacon
PREPARATION Print SCBA Skill Sheet
OBJECTIVES Properly DON PPE Utilizing Skill Sheet
OBJECTIVES Explain and Demonstrate use of the following SCBA Components: HUD & LED Light Patterns Voice Amplifier BYPASS Valve ICMTxR All Buttons and Modes
HUD & LED LIGHT PATERNS 4 Green Lights 76-100% Full 3 Green Lights 51-75% Full 2 Yellow Lights 26-50% Full 1 Red Light 0-25% Full
HUD & LED LIGHT PATERNS 1 Yellow Flashing Light = HUD Low Battery 2 Yellow Flashing Lights = Transmitter Low Battery (ICMTxR) Yellow Alternating Single & Double Flashing Lights = Both HUD & Transmitter Low Battery
HUD & LED LIGHT PATERNS 1 Orange LED = PASS Pre-Alarm Alternating Red/Orange LED = Evacuation Signal will be in conjunction with the running man on your ICMTxR readout screen
Clear Command Voice Amplifier One On/Off Button RedLight Indicates On Intrinsically Safe Hold Radio Lapel MIC 1” Away
BYPASS VALVE Check the MMR bypass valve operation • Grasp the red knob and turn it counter-clockwise • Listen and feel for airflow • One complete turn is fully open • Return bypass to the closed position by turning the red knob clockwise until closed
ICMTxR Buttons and Modes Mode Button Reset Button Manual Pass Alarm Thermal Sensor
ICMTxRGreenMode Button Pressing the Green Mode button once will momentarily refresh the display and backlight the ICMTxR While the display is still lit, pressing the mode button (green) again will toggle the display between current cylinder pressure and calculated remaining pressure time
ICMTxRGreenMode Button The remaining pressure time displayed is based on your average breathing rate over the last three minutes. Breathe faster: less time on display Breathe slower: more time on display
Continuous Operations Mode ON The Continuous Pressure Mode can only be activated when the system is pressurized In Continuous Operations Mode, the life of the batteries in the Receiver will be shortened The Continuous Operations Mode will deactivate if a low battery is present
Continuous Operations Mode ON To activate the Continuous Pressure Mode: • Push the top mode button (green) on the ICMTxR Unit and hold button in for 3 seconds. • Once LED’s lights come on, release button. Receiver will show air cylinder pressure level. • LED lights will stay on to show air cylinder pressure level drop.
Continuous Operations Mode OFF To deactivate the Continuous Pressure Mode: • Push the mode button (green) on the ICMTxR Unit and hold the button in for 3 seconds. • LEDs will revert to Automatic Mode showing only air cylinder pressure status at each 25% increment of full cylinder pressure. • The Heads-Up Display System will automatically turn itself OFF, approximately 60 seconds after the apparatus is depressurized. (A single red LED light will flash during this time).
Reset Button Upon returning to fresh air, close the cylinder valve completely and release all pressure from the system using the bypass valve. When the pressure falls below 200 psig, turn the device off by pressing the (Yellow) reset button 2 times in rapid succession. The ICMTxR Unit will beep 1 time when the button is pressed once. Pressing the (Yellow) button a second time will then sound three beeps (“bee-bop-bop”) to indicate that the unit is turned off. The lights will also stop flashing.

Thermal Alarm This chart shows the ICMTxR Unit thermal alarm activation curve. The thermal alarm sounds if the exposure exceeds the curve. The alarm will self-cancel depending on the severity of conditions. This may occur even though the temperature is above the thermal curve.
