PRE-ALARM
If the respirator remains motionless for more than twenty (20) seconds, the
PAK-ALERT distress alarm will automatically sound a pre-alarm
When the pre-alarm occurs, the green flashing light on the control console is
replaced by a bright red light which flashes approximately once a second
and is accompanied by an ascending/descending audible tone which in-
creases in volume during the pre-alarm cycle.
If the respirator user is not incapacitated or not in need of assistance, move
the respirator to reset the pre-alarm. When reset, the flashing red light will be
replaced by the flashing green and the ascending/descending tone will stop.
Remember that the motion sensor is in the sensor module on the respirator
backframe beneath the air cylinder. Actual movement of the respirator
backframe is required to reset the pre-alarm. Shaking the control console
will not reset the PAK-ALERT distress alarm .
To manually reset the pre-alarm, press and hold the reset button on the
side of the control console until three (3) quick audible chirps are heard
and the red flashing light on the control console is replaced by the green
flashing light.
FULL ALARM
If the respirator remains motionless through the twelve (12) second pre-alarm
cycle, the PAK-ALERT distress alarm will go into full alarm. This may indi-
cate that the user is incapacitated or in need of assistance and can not move.
Full alarm is indicated by a loud, almost continuous 3 tone chirp from the
sensor module accompanied by the flashing red signal light on the control
console. Ten (10) seconds after the full alarm condition starts, the Locator
Transmitter will begin to transmit the unique ID number for the unit. To reset
the full alarm condition, press the reset button twice. See FIGURE 4.
After the full alarm has been silenced by pressing the reset button twice, the
PAK-ALERT distress alarm will remain activated in the automatic mode with
the green light flashing once per second. As long as the respirator is pressur-
ized, there must be movement of the respirator at least every twenty (20)
seconds or the distress alarm will again go into pre-alarm followed by full
alarm as described above.
MANUAL ALARM
If the respirator user requires immediate assistance, pressing the manual alarm
button located on the front of the control console will immediately sound the full
alarm. See FIGURE 4. The manual alarm may be activated at any time, even
when the respirator is not pressurized.
If the manual alarm is activated when the respirator is not pressurized, press
the reset button twice to silence the alarm. The PAK-ALERT distress alarm
will remain on in automatic mode. To turn the unit off, press the reset twice
again while the unit is not in alarm mode.
Remember, the loud audible alarm and flashing red light can be turned on at
any time by pressing the manual alarm button on the control console.
