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 PASS DEVICE distress alarm will
be inactive. If there is no pressure in the system when the RESET but-
ton is pressed twice, there will be no beep sequence. The distress alarm
is now in the “OFF” condition. If there is air pressure in the system, the
PASS DEVICE 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.
