WARNING
FAILURE TO REPLACE THE BATTERIES AND/
OR CONTINUING WITH MULTIPLE USES OF
THE RESPIRATOR AFTER THE LOW BATTERY
CONDITION HAS BEEN INDICATED BY THE
PAK-ALERT DISTRESS ALARM MAY RESULT IN
FAILURE OF THE PAK-ALERT DISTRESS
ALARM DURING USE AND POSSIBLE INJURY
OR DEATH OF THE USER.
LOW BATTERY
In a low battery condition, the PAK-ALERT distress alarm will produce a single
audible chirp from the sensor module once every two (2) seconds and the
green light on the control module will not flash.
While in low battery condition, the PAK-ALERT distress alarm will continue to
operate for a period of time greater then the longest duration cylinder avail-
able for the respirator. However, the batteries must be replaced before the
respirator is used again. See THE BATTERY REPLACEMENT section of
these instructions.
If batteries are completely discharged or have not been installed, there will
be no light or sound and the unit will not operate.
BATTERY TEST
To test the batteries, verify that the PAK-ALERT distress alarm is in the off
condition (cylinder valve closed with no flashing green LED on the control con-
sole). Press and hold the reset button on the console.
A green light on the console will illuminate to indicate sufficient battery power
remaining. If a red light appears, the batteries must be replaced before the
respirator is used again.
TO TURN OFF THE PAK-ALERT DISTRESS ALARM
When use of the respirator with the PAK-ALERT distress alarm is no longer
required, close the cylinder valve on the respirator and vent the residual air
from the respirator system by opening the regulator purge valve. After all the
air flow stops, close the regulator purge valve and press the reset button twice
to turn off the PAK-ALERT distress alarm. The green flashing light will go out
and a fifteen (15) second beep sequence will sound from the sensor module.
When the unit sounds a quick two tone chirp, the PAK-ALERT distress alarm
will be inactive.
If the respirator cylinder valve is open and/or pressure remains in the respi-
rator, the PAK-ALERT distress alarm can not be turned off. Pressing the
reset button when the respirator is pressurized will only reset an alarm con-
dition and return the PAK-ALERT distress alarm to automatic mode.
If the respirator cylinder is turned off and depressurized without pressing the
reset button twice, the PAK-ALERT distress alarm will continue to monitor
motion in automatic mode. This means that the PAK-ALERT distress alarm
may be used to monitor motion after the respirator is turned off and depres-
surized. Resetting the full alarm after the respirator has been depressurized
will not turn off the PAK-ALERT distress alarm. Press the reset switch twice
with no alarm condition to turn off the PAK-ALERT distress alarm (the fifteen
(15) second beep sequence and two tone chirp will be heard).
