7. To check the pre-alarm, leave the SCBA motionless for twenty (20)
seconds. The green flashing light is replaced by a red flashing light. An
ascending/descending tone sounds, increasing in volume. Leave the
SCBA motionless.
8. 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 flashing light is replaced by a green flashing light and the
ascending/descending tone stops.
9. 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 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
flashing red light is replaced by a flashing 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 flashing of the red signal light on the control
console.
• The HHR sounds an alarm and displays the identification number
of the distress alarm, which appears on the label on the Sensor
Module or the Control Console. Use the SCROLL button on the
HHR to highlight the active ID number and press the ENTER
button on the HHR to select the displayed ID number. Point the
unit directly at and in close proximity to the SCBA. The signal
strength displayed will be at its highest value.
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 flashes. The unit resets to the automatic mode.
• The HHR resets to its non-alarm state.
4. Finish all SCBA checks involving air flow and close 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 flashing. Do not move the
SCBA; pre-alarm starts within twenty (20) seconds. Move the SCBA
slightly; pre-alarm resets, and the green light starts flashing 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 flashing light continues to flash while a fifteen-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.
