7. After the pre-alarm condition occurs, check the pre-alarm reset. Within
twelve (12) seconds of the pre-alarm, move the SCBA to activate
the motion sensor. The distress alarm resets to the automatic mode.
The red ashing light is replaced by a green ashing light and the
ascending/descending tone stops.
8. Continue with regular operational inspection of SCBA as directed
by SCBA instructions or your approved respiratory protection plan
procedure. During the inspection, the SCBA must be moved or turned
every thirty (30) seconds or less to prevent the sounding of the full
alarm.
After completion of all SCBA checks and before turning off the
cylinder valve:
1. Check the manual reset of the pre-alarm. Leave the SCBA motionless
until pre-alarm condition occurs. Within twelve (12) seconds, press
and hold the reset button. Three (3) chirps sound. Release the reset
button. The distress alarm resets to the automatic mode and the
ashing red light is replaced by a ashing green light.
2. To check the full alarm, leave the SCBA motionless until the pre-alarm
condition occurs. Do not reset. The full 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 loud alarm stops. The unit sounds three chirps
and the green light ashes. The unit resets to the automatic mode.
4. Finish all SCBA checks involving air ow and turn off the cylinder valve.
Use the purge valve to release all residual air pressure in the system.
With the cylinder valve closed (off):
1. Check the continuing operation of the distress alarm. The distress
alarm remains active with the green light ashing. Do not move the
SCBA; pre-alarm starts within twenty (20) seconds. Move the SCBA
slightly; pre-alarm resets, and the green light starts ashing again.
2. To turn the distress alarm off, press the reset button twice (press,
release and press again). If there is air pressure left in the system,
the green ashing light continues to ash while a fteen-second beep
sequence sounds from the Sensor Module as the residual air bleeds
from the system. As soon as the air has completely bled from system,
the unit sounds a quick two-tone chirp and the distress alarm will be
inactive. If there is no air pressure in the system when the RESET
button is pressed twice, there will be no beep sequence, only the quick
two-tone chirp. The distress alarm is now in the "OFF" condition. If
there is any air pressure left in the system, the distress alarm will return
to the active mode.
NOTE
IF THE LOW BATTERY INDICATION (ONE STEADY CHIRP EVERY
TWO (2) SECONDS WITH NO FLASHING LIGHTS) OCCURS AT ANY
TIME DURING REGULAR OPERATIONAL INSPECTION, DO NOT USE
THE SCBA. CHANGE THE BATTERIES IN THE SENSOR MODULE
IMMEDIATELY AND REPEAT THE REGULAR OPERATIONAL TEST
OR TAKE THE SCBA OUT OF SERVICE UNTIL THE BATTERIES
ARE CHANGED AND THE REGULAR OPERATIONAL TEST IS
SUCCESSFULLY PERFORMED.
WARNING
IF THE LOW BATTERY INDICATION (ONE
STEADY CHIRP EVERY TWO (2) SECONDS
WITH NO FLASHING LIGHTS) OCCURS AT
ANY TIME DURING REGULAR OPERATIONAL
INSPECTION, DO NOT USE THE SCBA. CHANGE
THE BATTERIES IN THE SENSOR MODULE
IMMEDIATELY AND REPEAT THE REGULAR
OPERATIONAL TEST OR TAKE THE SCBA
OUT OF SERVICE UNTIL THE BATTERIES ARE
CHANGED AND THE REGULAR OPERATIONAL
TEST IS SUCCESSFULLY PERFORMED.
FAILURE TO REPLACE THE BATTERIES AND/
OR CONTINUING WITH MULTIPLE USES OF THE
SCBA AFTER THE LOW BATTERY CONDITION
HAS BEEN INDICATED BY THE DISTRESS
ALARM MAY RESULT IN FAILURE OF THE
DISTRESS ALARM DURING USE AND POSSIBLE
INJURY OR DEATH OF THE USER.
