PROPERLY INSPECT THE COMPLETE SYSTEM
MAY RESULT IN FAILURE OF ONE COMPONENT,
WHICH COULD LEAD TO SERIOUS INJURY OR
DEATH.

1. While performing the visual inspection of the SCBA, visually inspect
all distress alarm enclosures, lenses, and wire conduits for cracks,
wear or other damage. If any damage is found, remove the SCBA from
service and tag it for repair by qualied personnel.
2. With the cylinder valve closed, press the manual alarm button, located
on the front of the distress alarm control console. The manual alarm
sounds a loud, almost continuous, 3-tone chirp accompanied by
ashing of the red signal light on the control console
3. Reset the manual alarm by pressing the reset button twice (fully
depress the reset button on the side of the control console, release,
and press again). The unit will sound three chirps and the green light
will ash.
4. Turn the distress alarm OFF by pressing the reset button twice again.
The unit will sound a two-tone chirp and the green light will go out.
5. Open the cylinder valve to pressurize the SCBA system. The
distress alarm sounds 3 quick chirps and the light on the control
console ashes green about once per second. The 3 chirps sound at
approximately the same time the VIBRALERT in the mask-mounted
regulator actuates briey. Make sure the air ow is stopped by pressing
the air saver/donning switch.
6. To check the pre-alarm, leave SCBA motionless for twenty (20)
seconds. The green ashing light is replaced by a red ashing light. An
ascending/descending tone sounds, increasing in volume. Leave the
SCBA motionless.
