7. After the pre-alarm condition occurs, check the pre-alarm reset. Within
twelve (12) seconds of the pre-alarm, move the respirator to activate the
motion sensor. The PAK-ALERT distress alarm shall reset to the automatic
mode. The red ashing light shall be replaced by a green ashing light
and the ascending/descending tone shall stop.
Continue with regular operational inspection of respirator as directed by
respirator instructions or your approved respiratory protection plan proce-
dure. During the inspection the respirator must be moved or turned every
thirty (30) seconds or less to prevent the sounding of the full alarm.
After completion of all respirator checks and before turning off the
cylinder valve:
1. Check the manual reset of the pre-alarm. Leave the respirator motionless
until pre-alarm condition occurs. Within twelve (12) seconds press and
hold the reset button. Three (3) chirps shall sound, then release button.
The distress alarm shall reset to the automatic mode and the ashing red
light will be replaced by a ashing green light.
2. To check the full alarm, leave the respirator motionless until the pre-alarm
condition occurs. Do not reset. The full alarm shall sound a loud almost
continuous 3 tone chirp accompanied by ashing of the red signal light
on the control console.
3. Reset the full alarm by pressing twice on the reset button located on
the side of the control console (fully depress reset button, release
and press again). The loud alarm shall stop. The unit will sound three
chirps and the green light will ash. The unit shall reset to the automatic
mode.
4. Finish all respirator 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 OFF:
1. Check the continuing operation of the distress alarm. The distress alarm
shall remain active with green light ashing. Do not move respirator,
pre-alarm shall occur with twenty (20) seconds. Move respirator slightly,
pre-alarm shall reset, green light shall start 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 will continue to ash while a fteen second beep sequence
is heard from the Sensor Module as the residual air bleeds from the
system. As soon as the air has completely bled from system, the unit will
sound a quick two tone chirp and the PAK-ALERT 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 PAK-ALERT 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 RESPIRATOR.
CHANGE THE BATTERIES IN THE SENSOR MODULE IMMEDIATELY AND
REPEAT THE REGULAR OPERATIONAL TEST OR TAKE THE RESPIRA-
TOR OUT OF SERVICE UNTIL THE BATTERIES ARE CHANGED AND THE
REGULAR OPERATIONAL TEST IS SUCCESSFULLY PERFORMED.
