THE SCOTT PAK-ALERT DISTRESS ALARM
DESCRIPTION
The PAK-ALERT SE + distress alarm is a PERSONAL ALERT SAFETY SYS-
TEM (PASS) intended to assist in locating a respirator user who is
incapacitated or in need of assistance. The SCOTT PAK-ALERT distress
alarm is an optional accessory intended only for the SCOTT AIR-PAK® 2.2/
3.0/4.5/Fifty Self-Contained Breathing Apparatus (SCBA).
The SCOTT PAK-ALERT distress alarm consists of a sensor module
mounted to the bottom of the respirator backframe, a pressure switch
mounted between the cylinder and gauge line, and a control console
mounted on the wearer’s right shoulder strap at the pressure gauge loca-
tion. The SCOTT PAK-ALERT distress alarm reaches full alarm in a total of
thirty (30) seconds.
In addition to the standard PASS functionality, the PAK-ALERT SE + is also
equipped with a SCOTT PAK-TRACKER locator device which is activated
with the PASS alarm. The locator has a transmitter which emits a radio
signal that can be tracked using the SCOTT PAK-TRACKER Hand Held
Receiver unit. The SCOTT PAK-ALERT SE + equipped with the locator
transmitter can be identified by the two RED covers on the Sensor Module.
See FIGURE 2.
The SCOTT PAK-TRACKER Locator System is a two part electronic system
consisting of a PAK-TRACKER Transmitter, which is integrated into the PAK-
ALERT SE + distress alarm, and a PAK-TRACKER Hand Held Receiver,
which is a directional receiver or “sniffer” used to locate the signal coming
from the PAK-TRACKER Transmitter. This line of electronic accessories is
for use by fire fighters, first responders, domestic preparedness and law
enforcement officers, as well as haz-mat and industrial users.
The PAK-TRACKER Transmitter works in conjunction with the PAK-ALERT
SE + distress alarm. A short time after activation of the full alarm, the unit
begins transmitting a signal with a unique ID number that can be received by
the PAK-TRACKER Hand Held Receiver.
The PAK-TRACKER Hand Held Receiver is then used as a directional sen-
sor to lead the rescue crew to the downed user. By pointing the
PAK-TRACKER Hand Held Receiver in the direction of the strongest signal,
the rescue crew can follow the signal to the downed user.

OPERATION OF THE SCOTT
PAK-ALERT DISTRESS ALARM
With proper batteries and a charged air cylinder installed, the PAK-ALERT
distress alarm device is automatically activated when the respirator is pres-
surized 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 flash approximately
once a second. See FIGURE 4. The PAK-ALERT distress alarm is now in the
automatic 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 auto-
matic 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 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.

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).

PRINCIPLES OF OPERATION
OF THE PAK-TRACKER LOCATOR SYSTEM
When a PAK-TRACKER Transmitter is activated, it sends out a radio signal
that is received by the PAK-TRACKER 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 un-
derstanding the operation of the SCOTT PAK-TRACKER Locator System.
When the PAK-TRACKER Transmitter is activated, the radio signal will ema-
nate equally in all directions. The PAK-TRACKER Hand Held Receiver
indicates the relative strength of the radio signal on the display in numbers
from 10 to 99 where 10 is the weakest signal and 99 is the strongest signal.
The relative strength of the radio signal detected by the PAK-TRACKER Hand
Held Receiver will vary depending on:
1. The distance from the Transmitter to the Hand Held Receiver,
2. What path the radio signal has taken to get to the Hand Held Receiver.
The further the signal has traveled as well as how often it has been reflected will
determine the relative strength of the signal when it reaches the Hand Held
Receiver. The PAK-TRACKER Hand Held Receiver is a directional receiver in
that it will display a higher relative signal strength when it is pointed at the specific
area where the signal is coming from. Since the signal is coming to the PAK-
TRACKER Hand Held Receiver from all directions in varying strengths, the
receiver is very sensitive in responding to small differences between a stronger
signal that is coming most directly from the transmitter and a weaker signal that
has reflected several times before reaching the receiver. The user of the Hand
Held Receiver must interpret the readings on the Hand Held Receiver display
and follow the strongest signal to reach the activated Transmitter.
The radio signal from the Transmitter will always follow a path of least resis-
tance to the receiver in the Hand Held Receiver. The radio signal will pass
through some materials and surfaces, while it will tend to reflect off other
materials. In general, the radio signal will pass through glass, wood, or light
building materials. The signal will reflect off large metal objects, concrete
walls or floors, brick, or concrete block construction.
The reflected signal will continue to move following the path of least resis-
tance through openings, down halls, and through doors and windows, or
through holes or gaps in walls and floors. The signal will follow the open
cavities of a building such as halls, stairways, or elevator shafts.
The PAK-TRACKER Hand Held Receiver and PAK-TRACKER Transmitter
are used to monitor personnel location both indoors and outdoors. Outdoors,
the range is approximately 1000 feet / 300 meters line of sight (LOS). If the
PAK-TRACKER Transmitter is located inside a building and a PAK-TRACKER
Hand Held Receiver is located outside the building, range is approximately
400 feet / 125 meters. If both the PAK-TRACKER Transmitter and PAK-
TRACKER Hand Held Receiver are totally indoors, the system has a range
of up to 250 feet / 75 meters.
WARNING
DO NOT USE THE HAND HELD RECEIVER IN
ATMOSPHERES WHERE FLAMMABLES ARE
OPENLY HANDLED OR MAY BE PRESENT CON-
TINUOUSLY. THE HAND HELD RECEIVER MAY
BE USED IN ATMOSPHERES WHERE FLAM-
MABLES ARE NORMALLY CONTAINED OR ARE
IN THE FORM OF DEPOSITS OR DUST. SEE THE
SAFETY STATEMENT ON PAGE 4. FAILURE TO
VERIFY THAT THE ATMOSPHERE IS NOT FLAM-
MABLE OR EXPLOSIVE BEFORE USING THE
HAND HELD RECEIVER MAY RESULT IN A FIRE
OR AN EXPLOSION WHICH COULD RESULT IN
SERIOUS INJURY OR DEATH.
RESTRICTED USE IN SOME LOCATIONS
The Hand Held Receiver may not be suitable for use in certain atmospheres
which could contain flammable or explosive gases in unknown levels. If any
of the following conditions may be present, do not use the Hand Held Re-
ceiver:
–Ignitable concentrations of flammable gases or vapors may be present
under normal conditions
–Ignitable concentrations of such gases or vapors may exist because of
repair or leakage
–Breakdown or faulty operation of equipment or processes might release
ignitable concentrations of flammable gases or vapors.
Always check for the presence of flammable or explosive gases before en-
tering an unknown atmosphere with the Hand Held Receiver.

DETECTING AND AVOIDING
RADIO FREQUENCY INTERFERENCE
When any electronic device is adversely affected by radio waves, Radio Fre-
quency Interference (RFI) is said to have occurred. All electronic devices like
the PAK-ALERT SE + distress alarm may be subject to the effects of RFI.
Radio transmissions from the antennas of radios including those used by fire
fighters, police and other public safety related personnel may produce RFI in
the PAK-ALERT SE + distress alarm. RFI may occur while the radio is trans-
mitting if the respirator equipped with the PAK-ALERT SE + 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
SE + distress alarm. See FIGURE 5.
Be aware of the symptoms of RFI. A PAK-ALERT SE + distress alarm af-
fected 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 flash without sounding the
alarm. In rare circumstances, an alarm which was sounding may stop.
If the PAK-ALERT SE + 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 SE +.
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 SE + distress
alarm will typically resume normal operation after experiencing RFI.
11
DRAFT COPY
DRAFT COPY
In some circumstances after experiencing RFI, it may be necessary to re-
move the unit from service. Remove and reinstall the batteries to reset the
unit (see BATTERY REPLACEMENT section of this instruction, page 10).
Then inspect and return the unit to service.
If the PAK-ALERT SE + 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 SE + DISTRESS ALARM TO VERIFY THAT IT IS
FUNCTIONING PROPERLY. IF THE GREEN LIGHT ON THE CONTROL
CONSOLE DOES NOT RESUME FLASHING IN THE NORMAL MANNER
AFTER EXPERIENCING THE SYMPTOMS OF RFI, OR IF THE UNIT CON-
TINUES TO MALFUNCTION IN ANY OTHER WAY, PROCEED TO A SAFE
AREA, REMOVE THE RESPIRATOR FROM SERVICE AND TAG FOR RE-
PAIR BY AUTHORIZED PERSONNEL.
Minimize or eliminate the effects of RFI by protecting the PAK-ALERT SE +
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.

the following inspection procedures with the REGULAR OPERATIONAL IN-
SPECTION procedures defined in your respirator instructions. If any
malfunction of the respirator or the PAK-ALERT distress alarm is noted
during the inspection, remove the respirator from service and tag for repair
by authorized personnel.
To test the PAK-ALERT locator transmitter, you must have an operating
SCOTT PAK-TRACKER Hand Held Receiver.
NOTE
IF THIS INSPECTION IS DONE IN DIRECT SUNLIGHT IT MAY BE HELP-
FUL TO SHADE THE LENS ON THE CONTROL MODULE WITH YOUR
HAND TO BE SURE THE LIGHTS ARE FLASHING AS DESCRIBED.
1. While performing the visual inspection of the respirator, visually in-
spect all PAK-ALERT distress alarm enclosures, lenses, and wire
conduits for cracks, wear or other damage. If any damage is found,
remove the respirator from service and tag for repair by qualified per-
sonnel.
2. Turn on the SCOTT PAK-TRACKER Hand Held Receiver according to
the operating instructions provided with the unit. Position the Hand Held
Receiver near by.
3. With the cylinder valve closed, press the manual alarm button, located
on the front of the control console.
a) The manual alarm shall sound a loud almost continuous 3 tone chirp
accompanied by flashing of the red signal light on the control console.
b) The PAK-TRACKER Hand Held Receiver will sound an alarm and dis-
play the Identification Number of the PAK-ALERT which appears on
the label on the Sensor Module or the Control Console. Use the
SCROLL button on the Hand Held Receiver to highlight the active ID
number and press the ENTER button on the Hand Held Receiver to
select the displayed ID number. Point the unit directly at and in close
proximity to the respirator. The signal strength displayed will be at its
highest value.
4. Reset the manual alarm by pressing twice on the reset button located
on the side of the control console (fully depress reset button, release
and press again).
a) The unit will sound three chirps and the green light will flash.
b) The PAK-TRACKER Hand Held Receiver will reset to its non-alarm
state.
5. Turn the PAK-ALERT unit off by pressing the reset button twice again.
The unit will sound a two tone chirp and the green light will go out.
6. Open the cylinder valve to pressurize the respirator system. The PAK-
ALERT distress alarm shall sound 3 quick chirps and the light on the
control console shall begin flashing green about once a second. The 3
chirps will sound approximately the same time the VIBRALERT® in the
mask mounted regulator actuates briefly. Make sure the air flow is stopped
by pressing the air saver/donning switch.
7. To check the pre-alarm, leave respirator motionless for twenty (20) sec-
onds. The green flashing light shall be replaced by a red flashing light.
An ascending/descending tone will sound increasing in volume. Leave
the respirator motionless.
8. 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. PAK-ALERT distress alarm shall reset to the automatic
mode. The red flashing light shall be replaced by a green flashing light
and the ascending/descending tone shall stop.

WARNING
IF THE LOW BATTERY INDICATION (ONE
STEADY CHIRP EVERY TWO (2) SECONDS
WITH NO FLASHING LIGHTS) OCCURS AT ANY
TIME DURING REGULAR OPERATIONAL IN-
SPECTION, DO NOT USE THE RESPIRATOR.
CHANGE THE BATTERIES IN THE SENSOR
MODULE IMMEDIATELY AND REPEAT THE
REGULAR OPERATIONAL TEST OR TAKE THE
RESPIRATOR OUT OF SERVICE UNTIL THE
BATTERIES ARE CHANGED AND THE REGULAR
OPERATIONAL TEST IS SUCCESSFULLY PER-
FORMED.
Continue with regular operational inspection of respirator as directed by
respirator instructions or your approved respiratory protection plan pro-
cedure. 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 cyl-
inder valve:
1. Check the manual reset of the pre-alarm. Leave the respirator motion-
less until pre-alarm condition occurs. Within twelve (12) seconds press
and hold the reset button. Three (3) chirps shall sound, then release
button. The PAK-ALERT distress alarm shall reset to the automatic mode
and the flashing red light will be replaced by a flashing green light.
2. To check the full alarm, leave the respirator motionless until the pre-
alarm condition occurs. Do not reset.
a) The full alarm shall sound a loud almost continuous 3 tone chirp ac-
companied by flashing of the red signal light on the control console.
b) The PAK-TRACKER Hand Held Receiver will sound an alarm and dis-
play the Identification Number of the PAK-ALERT which appears on
the label on the Sensor Module or the Control Console. Use the
SCROLL button on the Hand Held Receiver to highlight the active ID
number and press the ENTER button on the Hand Held Receiver to
select the displayed ID number. Point the unit directly at and in close
proximity to the respirator. The signal strength displayed will be at its
highest value.
4. 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).
a) The loud alarm shall stop. The unit will sound three chirps and the
green light will flash. The unit shall reset to the automatic mode.
b) The PAK-TRACKER Hand Held Receiver will reset to its non-alarm
state.
5. Finish all respirator checks involving air flow 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 PAK-ALERT distress alarm. The
PAK-ALERT distress alarm shall remain active with green light flash-
ing. Do not move respirator, pre-alarm shall occur with twenty (20)
seconds. Move respirator slightly, pre-alarm shall reset, green light shall
start flashing again.
2. To turn the PAK-ALERT distress alarm off, press the reset button twice
(press, release and press again). The green flashing light will go out and
a fifteen (15) second beep sequence will be heard from the sensor mod-
ule. When this sequence is complete, unit will sound a two tone chirp.
