PAK-ALERT DISTRESS ALARM
The SCOTT PAK-ALERT distress alarm consists of a Sensor Module mounted
to the bottom of the respirator backframe and a control console mounted on
the wearer’s right shoulder strap at the pressure gauge location. The SCOTT
PAK-ALERT distress alarm reaches full alarm in a total of thirty (30) seconds
after detecting that the respirator user is motionless. The alarm may also be
activated manually.
The SCOTT PAK-ALERT distress alarm is approved by the National Institute
of Occupational Safety and Health (NIOSH) on all models of SCOTT SCBA
except as specied in the limitations of use on the SCBA approval label and in
the SCBA Operating and Maintenance Instructions. The PAK-ALERT distress
alarm is approved under NFPA 1982, 2013 edition as a PASS device when
used on an approved SCOTT respirator.
NIOSH certied SCBA’s are limited to a maximum weight of 35 lbs. When the
PAK-ALERT distress alarm is used with a one hour duration SCOTT SCBA,
either the Kevlar1 wrapped (SCOTT P/N 804222-01) or Carbon wrapped
(P/N 804723-XX) cylinder and valve assembly must be used to keep the total
weight under 35 lbs. limit. Using the PAK-ALERT distress alarm with berglass
wrapped one hour cylinder and valve assemblies, (SCOTT P/N 804107-01
or P/N 802827-01), will exceed 35 lbs.
Installation of a SCOTT PAK-ALERT distress alarm on a SCOTT AIR-PAK
SCBA requires some disassembly of the respirator. Installation instructions
are included with the eld installation kit available from your SCOTT distribu-
tor or from SCOTT SAFETY.
The PAK-ALERT distress alarm is a PERSONAL ALERT SAFETY SYSTEM
(PASS) intended to assist in locating a respirator user who is incapacitated
or in need of assistance. The SCOTT PAK-ALERT distress alarm, P/N
201160-SERIES, is an optional accessory intended only for use on SCOTT
SCBA respirators including the AIR-PAK X3 CGA and AIR-PAK X3 SNAP
CHANGE Self-Contained Breathing Apparatus (SCBA). This line of electronic

OPERATION OF THE SCOTT PAK-ALERT DISTRESS
ALARM
With proper batteries and a charged air cylinder installed, the PAK-ALERT
distress alarm is automatically activated when the respirator is pressurized
by opening the cylinder valve of the respirator.
To indicate activation, the Sensor Module will sound 3 quick audible chirps
and the green light located on the control console will ash every three (3)
seconds. See FIGURE 4. The PAK-ALERT distress alarm is now in the au-
tomatic mode.
In the automatic mode, the SCOTT PAK-ALERT distress alarm constantly
monitors motion of the respirator backframe. The Sensor Module is located
on the respirator backframe beneath the air cylinder and contains the motion
sensor and the audible alarm. If the Sensor Module does not sense motion
of the respirator for twenty (20) seconds, the PAK-ALERT distress alarm will
signal a pre-alarm condition. If there is still no motion of the respirator for the
next twelve (12) seconds the full alarm will sound.
The SCOTT PAK-ALERT distress alarm will remain activated in the au-
tomatic mode until turned OFF according to these instructions.

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 ashing light on the control console is
replaced by a bright red light which ashes in cadence with pre-alarm tone and
is accompanied by an ascending/descending audible tone which increases
in volume during the pre-alarm cycle. In addition, the lights in the Heads-Up
Display will ash alternately from one side to the other.
If the respirator user is not incapacitated or not in need of assistance, move
the respirator to reset the pre-alarm. When reset, the ashing red light will
be replaced by the ashing green, the ascending/descending tone will stop,
and the Heads-up Display will return to showing the current cylinder pressure.
Remember that the motion sensor is in the Sensor Module on the respirator
backframe beneath the air cylinder. Actual movement of the respirator back-
frame 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 ashing light on the control console is replaced by the green
ashing 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 indicate
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 ashing 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. After an
additional (10) second delay, the Pak-Tracker Locator transmitter in the unit
will begin transmitting the unique ID number that can be received by the
Pak-Tracker Hand Held 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 ashing once per second. As long as the respirator is pres-
surized, 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. In manual alarm mode, the Pak-Tracker
Locator transmitter in the unit will begin transmitting the unique ID number
that can be received by the Pak-Tracker Hand Held Unit with NO delay.
Remember, the loud audible alarm and ashing red light can be turned on at
any time by pressing the manual alarm button on the control console.
WARNING
USERS OF RESPIRATORS EQUIPPED WITH
THE PAK-ALERT DISTRESS ALARM MUST BE

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 ash.
In low battery condition, the PAK-ALERT distress alarm will not emit the 3
beeps when cylinder valve is activated.
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
available 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 ashing green LED on the control
console). Press and hold the reset button on the console.
A green light on the console will illuminate to indicate sufcient 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
ow stops, close the regulator purge valve and press the reset button twice
to turn off the PAK-ALERT distress alarm. 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 button is
pressed twice, there will be no fteen second beep sequence. When the unit
sounds a quick two tone chirp, the PAK-ALERT distress alarm is inactive. If
there is any air pressure left in the system, the PASS DEVICE distress alarm
will return to the active mode.
If the respirator cylinder valve is open and/or pressure remains in the respira-
tor, the PAK-ALERT distress alarm can not be turned off. Pressing the reset
button when the respirator is pressurized will only reset an alarm condition
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 (there will
be no fteen (15) second beep sequence and two tone chirp will be heard).

WARNING
CONTINUED TRAINING AND PRACTICE IN A
VARIETY OF SITUATIONS IS ESSENTIAL TO
DEVELOPING THE SKILLS TO PROPERLY
INTERPRET THE INFORMATION PROVIDED BY
THE PAK-TRACKER LOCATOR SYSTEM. USE
OF THIS EQUIPMENT WITHOUT TRAINING AND
PRACTICE MAY JEOPARDIZE ALL PERSONNEL
INVOLVED WHICH COULD LEAD TO SERIOUS
INJURY OR DEATH.
PRINCIPLES OF OPERATION OF THE PAK-TRACKER
LOCATOR SYSTEM
The SCOTT PAK-TRACKER locator system is a two part electronic system
consisting of a Hand Held Receiver and a Transmitter. When a Transmitter
is activated, it sends out a radio signal in all directions that is received by the
Hand Held Receiver. Understanding how the radio signal from a Transmitter
behaves and how the Hand Held Receiver receives and displays the strength
of that signal are critical to understanding the operation of the SCOTT PAK-
TRACKER locator system. Successful operation of the PAK-TRACKER
Locator system depends heavily on the interpretation of the relative signal
strength information displayed on the Hand Held Receiver along with all other
available information about the possible location of the activated transmit-
ter.
The Hand Held Receiver is very sensitive in responding to small differences
in signal strength. The relative strength of the Transmitter signal detected by
the Hand Held Receiver will vary depending on:
1. The distance from the Transmitter to the Hand Held Receiver,
2. The path the Transmitter signal has taken to get to the Hand Held Re-
ceiver,
3. The materials between the Transmitter and the Hand Held Receiver which
may have affected the signal from the Transmitter.
The user of the Hand Held Receiver must interpret the readings on the Hand
Held Receiver display along with other information, such as:
– training and knowledge in systematic search and rescue techniques,
– their sense of sight (watch where you are going),
– their sense of sound (listen for an activated PASS device),
– the deployment of the missing personnel,
– knowledge of the building layout and building materials,
Do not rely solely on the readings from the Hand Held Receiver to locate the
activated Transmitter.
Refer to the PAK-TRACKER Locator System User Instructions provided with
your PAK-TRACKER equipment for complete details on the use of the PAK-
TRACKER Locator System.

WARNING
BE AWARE OF THE POTENTIAL EFFECT OF
RADIO TRANSMISSIONS FROM BASE STATION
OR TRUCK MOUNT RADIOS WHEN USING A
RESPIRATOR WITH THE PAK-ALERT DISTRESS
ALARM. CLOSE PROXIMITY OF RADIO
EQUIPMENT TO THE PAK-ALERT DISTRESS
ALARM DURING RADIO TRANSMISSION MAY

DETECTING AND AVOIDING RADIO FREQUENCY
INTERFERENCE
When any electronic device is adversely affected by radio waves, Radio
Frequency Interference (RFI) is said to have occurred. All electronic devices
like the PAK-ALERT distress alarm may be subject to the effects of RFI. Ra-
dio transmissions from the antennas of radios including those used by re
ghters, police and other public safety related personnel may produce RFI
in the PAK-ALERT distress alarm. RFI may occur while the radio is transmit-
ting if the respirator equipped with the PAK-ALERT distress alarm is in close
proximity to a base station or high-powered vehicle mounted radio, or if the
antenna of a personal portable hand held radio is touching or within six (6)
inches of the Control Console or Sensor Module of the PAK-ALERT distress
alarm. See FIGURE 5.
Be aware of the symptoms of RFI. A PAK-ALERT distress alarm affected by
RFI may temporarily give false indications such as the sudden sounding of
the loud continuous three-tone chirp of the full alarm. In some instances the
lights on the control console may ash without sounding the alarm. In rare
circumstances, an alarm which was sounding may stop.
If the PAK-ALERT exhibits any of the symptoms of RFI, identify the source
of the RFI and do the following:
– If the symptoms of RFI occur when standing near a base station trans-
mitting antenna or a truck mounted radio antenna, move away from the
antenna until the symptoms stop.
– If the symptoms of RFI occur while transmitting on a hand-held radio,
move the radio away from the PAK-ALERT .
CHECK THE CONTROL CONSOLE AND BE CERTAIN THE GREEN LIGHT
IS FLASHING NORMALLY WHEN THE INTERFERENCE STOPS, REGARD-
LESS OF THE SOURCE.
In normal usage with the air cylinder open, the PAK-ALERT distress alarm

will typically resume normal operation after experiencing RFI.
If the PAK-ALERT distress alarm is affected by RFI when the respirator air
supply is turned off or the cylinder is empty, the distress alarm could be
turned off during use. If this occurs, depress the RED Manual Alarm Button
to activate the alarm.
IF THE SYMPTOMS OF RFI OCCUR, THE RESPIRATOR USER MUST
CHECK THE PAK-ALERT DISTRESS ALARM TO VERIFY THAT IT IS FUNC-
TIONING PROPERLY. IF THE GREEN LIGHT ON THE CONTROL CONSOLE
DOES NOT RESUME FLASHING IN THE NORMAL MANNER AFTER EX-
PERIENCING THE SYMPTOMS OF RFI, OR IF THE UNIT CONTINUES
TO MALFUNCTION IN ANY OTHER WAY, PROCEED TO A SAFE AREA,
REMOVE THE RESPIRATOR FROM SERVICE AND TAG FOR REPAIR BY
AUTHORIZED PERSONNEL.
Minimize or eliminate the effects of RFI by protecting the PAK-ALERT with
the following steps:
– Maintain a safe distance from a base station transmitting antenna or a
truck mounted radio antenna.
– Keep the antennas of hand held radios at least six (6) inches away from the
CONTROL CONSOLE or the SENSOR MODULE. See FIGURE 5.
FIGURE 5

CAUTION
RESPIRATOR SYSTEM MUST NOT BE
PRESSURIZED WHEN BATTERIES ARE BEING
INSTALLED. DAMAGE TO THE ELECTRONIC
COMPONENTS MAY RESULT IF BATTERIES
ARE INSTALLED WITH SYSTEM PRESSURIZED.
SCOTT respirators equipped with the PAK-ALERT distress alarm
require six (6) “AA” cell batteries for operation. The six (6) batteries
power the Heads-Up Display, the PASS device, and the PAK-TRACK-
ER Transmitter. The batteries should be replaced only by a trained
maintenance technician in a clean area known to be nonflammable.
NOTE
WHEN RECEIVING AIR-PAK RESPIRATORS, THE USER SHOULD UP-
DATE THE ELECTRONICS TO THE LOCAL TIME ZONE USING THE
PAK-LINK PROGRAMMER (P/N 200673-01).
Replace batteries as follows:
1. Close respirator cylinder valve, open regulator purge valve letting out
all the trapped air, close regulator purge valve, press the reset button
twice. 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 button is pressed twice,
there will be no beep sequence. If there is air pressure in the system, the
PASS DEVICE distress alarm will return to the active mode.
NOTE
ALWAYS BE SURE THAT CYLINDER VALVE IS OFF AND THE PASS
DEVICE IS COMPLETELY INACTIVE BEFORE CHANGING BATTERIES.
NEVER REMOVE OR REPLACE BATTERIES WITH SYSTEM PRESSUR-
IZED OR DAMAGE MAY OCCUR TO ELECTRONIC COMPONENTS.
2. When replacing batteries on respirators, remove the cylinder and place
the respirator in a clean, non-hazardous area.
3. Use a Phillips driver to remove the Battery Housing Cover as shown in
FIGURE 6. Carefully remove the cover and set aside.
4. Remove used batteries from battery compartment by sliding them out of
the battery compartment.
5. Install six (6) fresh new “AA” batteries of the same type. Always replace
all batteries at the same time.
The battery holder is marked with the style and orientation of the batteries
required. See FIGURE 7.
Use six (6) each of one of the following 1.5 volt AA batteries:
– Duracell2 Alkaline MN1500
– Duracell Alkaline MX1500
– Duracell Alkaline PC1500
– Duracell Quantum QU1500
– Energizer3 Alkaline EN91
– Energizer Alkaline E91
Do not mix batteries. Verify correct orientation of batteries as shown on
label inside the battery holder.

NEW BATTERIES OF THE TYPE INDICATED
ABOVE AND THAT THEY HAVE BEEN INSTALLED
PROPERLY.
FIGURE 7
BE SURE SEALING
SURFACES ARE CLEAN
BEFORE REASSEMBLY
6. The battery cover must be installed so that it is water tight after replace-
ment. Clean the sealing rib around battery compartment and sealing face
of the cover, shown in FIGURE 7, by wiping with a clean damp cloth to
remove any dirt or foreign matter which might prevent a proper seal. Check
cover gasket for tears or cuts. If damage is found, remove respirator from
service and tag for repair by authorized personnel.
7. To install battery cover, align the three grooves on the cover with the three
tabs on the battery compartment and tighten the cover screw. The cover
must be water tight to prevent damage to the equipment.
8. To test the batteries, verify that the PAK-ALERT distress alarm is in the off
condition (cylinder valve closed with no ashing green LED on the control
console).
a) Press and hold the reset button on the console. A GREEN light on the
console indicates sufcient battery power and that the batteries are
properly installed.
b) If the unit displays the LOW BATTERY condition or no light at all, verify
that the batteries are properly installed. If the batteries were properly
installed, remove the batteries and replace with a new set of six (6)
batteries.
c) If another set of properly installed batteries will still not produce a
GREEN light on the battery test, remove the unit from service and mark
for repair by authorized personnel.
AFTER REPLACEMENT OF BATTERIES, PERFORM A REGULAR
OPERATIONAL INSPECTION BEFORE RETURNING RESPIRATOR TO
SERVICE.
CAUTION
IMPROPER BATTERY COVER INSTALLATION
