SEMS II PERSONAL DISTRESS ALARM CONTROL CONSOLE
The SCOTT SEMS II PDA Portable Unit, when added to a SCOTT SCBA respirator
consists of a Sensor Module with battery compartment mounted to the bottom of
the respirator backframe, a pressure gauge with transducer, and a Control Console
mounted on the wearer’s right shoulder strap at the pressure gauge location. The
SEMS II PDA Portable Unit requires six (6) AA batteries to operate the Sensor Module
on the backframe.
The SEMS II PDA Control Console is
integrated into the SCOTT SCBA as a
part of the remote air pressure gauge
assembly which hangs over the right
shoulder of the respirator user. The
Control Console also operates the
PERSONAL ALERT SAFETY SYSTEM
(PASS) distress alarm intended to as-
sist in locating a respirator user who is
incapacitated or in need of assistance.
The PASS distress alarm in this model
reaches FULL ALARM in a total of 30
(thirty) seconds. The Control Console
has a set of status lights, a dial air pres-
sure gauge, and three control buttons
which can easily be pressed with gloved
hands. Power is supplied by batteries in
the SEMS II PDA battery compartment
on the SCBA backframe.
WARNING
FOLLOW REGULAR OPERATIONAL INSPECTION
PROCEDURE EXACTLY. IF THE SEMS II
DISTRESS ALARM DOES NOT ACTUATE, OR IF
ANY OTHER FEATURE DOES NOT OPERATE AS
DESCRIBED OR IF ANY OTHER OPERATIONAL
MALFUNCTION IS NOTED, DO NOT USE THE
RESPIRATOR.
WARNING
THE SEMS II ACCOUNTABILITY SYSTEM
COMMUNICATES ONLY WITH FIREFIGHTER
RESOURCES (RESPIRATOR USERS) USING
A SCOTT SCBA EQUIPPED WITH THE SEMS
II ACCOUNTABILITY SYSTEM INTEGRATED
INTO THE PERSONAL DISTRESS ALARM.
OTHER FIREFIGHTER RESOURCES WHO ARE
NOT USING A PROPERLY EQUIPPED SCOTT
RESPIRATOR MAY BE ADDED FOR ACCOUNT-
ABILITY PURPOSES, BUT THEY WILL NOT BE
AUTOMATICALLY ACCESSIBLE THROUGH
THE COMMUNICATIONS FUNCTIONS OF THE
SYSTEM. FAILURE TO RECOGNIZE THE STATUS
OF FIREFIGHTER RESOURCES MAY RESULT IN
SERIOUS INJURY OR DEATH.
the IMPERIUM software. When logged on, all the SEMS II PDA Portable Units
communicate to the Base Station directly and/or through other logged on units forming
a communications "mesh network" to the Base Station. This extends the range for
the units furthest away from the Base Station. Because of this mesh network system,
the signal strength of each user may change as the network constantly re-adjusts to
the movement of the users.
SCBAs addtionally equipped with an optional BLUETOOTH backup communication,
provide a limited one-way transmission from the control console to the Base Station
at one minute intervals via a APX™ RF Modem/ Radio network. No information can
be transmitted back to the respirator user when transmitting in BLUETOOTH mode.
In units equipped with both SEMS II and BLUETOOTH, the SEMS II is the primary
mode of communication between the console and Base Station. BLUETOOTH will
only transmit information via radio to the base station when the SEMS II is out of
range or otherwise unable to link to the system. Once the SEMS II transmission has
resumed, or the SCBA is turned off, the BLUETOOTH transmission will discontinue.

NOTE
SEMS II ENABLED PDA UNITS HAVE BIDIRECTIONAL COMMUNICATION CAPABILI-
TIES AND CAN BOTH TRANSMIT AND RECEIVE DATA BETWEEN THE PDA AND
THE BASE STATION. WHEN IN BLUETOOTH MODE, BLUETOOTH ENABLED PDA
CONTROL CONSOLES ARE UNIDIRECTIONAL ONLY. THEY CAN SEND DATA TO
THE BASE STATION THROUGH APPROVED BLUETOOTH ENABLED PORTABLE
TWO-WAY RADIOS BUT CANNOT RECEIVE DATA BACK FROM THE BASE STATION.
No personal alert safety system, respirator, or combination of personal alert safety
system and respirator, by themselves, can provide complete protection in dangerous
situations. However, using an alarm and a respirator in accordance with the require-
ments of an organized respiratory protection program is one of the many safety
precautions which should be taken to avoid personal injury or death.
These instructions explain the operation and use of the main functions of the ac-
countability system. Follow the REGULAR OPERATIONAL INSPECTION procedure
as described. If any function fails to operate as described, do not use the equipment.
Remove the unit from service and tag for repair by authorized personnel.
This system communicates only with Fireghter Resources (Respirator Users) using
a SCOTT SCBA equipped with the SEMS II Accountability System integrated into the
Personal Distress Alarm.
Complete training in the use of the SEMS II and Bluetooth equipment is required
before actual use in a hazardous envirionment. If the equipment does not work as
described in these instructions, remove the equipment from service and tag for repair
by authorized personnel.

When a respirator user opens the cylinder valve and begins use of a SCOTT SCBA
equipped with the SEMS II PDA, the Accountability System electronics will automati-
cally begin to operate. If the IMPERIUM Base Station is present at time of entry the
SEMS II PDA will attempt to log-in to the Base Station. BLUETOOTH enabled units
will attempt to log-in to the Base Station once the paired radio is turned on and they
are communicating. When the SEMS II is out of range or otherwise unable to link
to the system, the BLUETOOTH information will display on the base station. Once
the SEMS II transmission has resumed, or the SCBA is turned off, the BLUETOOTH
display will discontinue. It is the responsibility of the Incident Commanders from each
re company to coordinate activities with each other and to maintain accountability
for all participating reghter resources.
Multiple organizations with SEMS II Accountability System equipment can operate
at a single event scene since each Base Station operator can select and monitor
which users log in on their Base Station. Multiple base stations may also be used at
a single event to manage resources from several different re companies. SEMS II
users will appear in one base station at a time. The user can be rejected and connect
to an alternate base station.
BLUETOOTH signats transmit to a base station modem via radio. The BLUETOOTH
users will simultaneously appear on ALL base stations that are congured to the same
radio channel. BLUETOOTH units will continue to display on the base station screen
until the PDA unit either re-establishes SEMS II communication or it is turned off and
removed from the base station.
The SEMS II Accountability System and Personal Distress Alarm can be quickly pro-
grammed with the identication of the SCBA user using the SEMS II Accountability
RFID Tag, Badge, or Button. Programming the ID Tags and Portable Units allows
the organization to customize the identication of the SEMS II Portable Units. See
SEMS II Programming Guide, SCOTT Imperium Commissioning for complete details
of programming the SEMS II equipment. SCOTT recommends re-programming with
the RFID card in accordance with your organization's procedures to assure that the
user's unique ID number is in use at all times.

PAK-TRACKER LOCATOR SYSTEM
The SCOTT PAK-TRACKER Locator System is a two part electronic system
consisting of a PAK-TRACKER Transmitter integrated into the SCOTT SEMS II
distress alarm, and a PAK-TRACKER Hand Held Receiver, which is a directional
receiver used to locate the signal coming from the PAK-TRACKER Transmitter. The
PAK-TRACKER locator system transmitter is activated with the PASS alarm. The
transmitter emits a radio signal with a unique ID number that can be tracked using
the SCOTT PAK-TRACKER Hand Held Receiver unit.
The PAK-TRACKER Hand Held Receiver is then used as a directional receiver to
assist in leading the rescue team to the activated transmitter. By pointing the PAK-
TRACKER Hand Held Receiver in the direction of the strongest relative signal, the
rescue crew can follow the signal toward the respirator user who is incapacitated or
in need of assistance.
Use of this equipment must be part of a complete personnel accountability system that
includes procedures for monitoring the deployment and condition of all users. Do not
rely on the PAK-TRACKER Locator System as the only technique for locating miss-
ing personnel. Failure to use this equipment properly may actually increase the time
needed to locate and rescue personnel. TRAINING AND PRACTICE IN REALISTIC
EMERGENCY SIMULATIONS IS REQUIRED BEFORE USE OF THIS EQUIPMENT.
The users must become thoroughly familiar with the operation and the limitations of
the locator system before entering a potentially hazardous or life threatening situation.
The PAK-TRACKER Locator System User Instructions, SCOTT part number 595102-
01, contain essential information on the use of the locator system and must be used as
the basis of training for use of the whole system including use with a SEMS II distress
alarm equipped with the PAK-TRACKER Transmitter. The PAK-TRACKER Locator
System User Instructions include an overview of the system operation, limitations of
the system, as well as any user level maintenance for the PAK-TRACKER Locator
System equipment. Copies of the PAK-TRACKER Locator System User Instructions
are available from your SCOTT distributor or from SCOTT Safety.

ACTIVATION
Prepare the respirator for use according to the user instructions provided with the
respirator. Install the batteries in the SEMS II Sensor Module according to the BAT-
TERY INSTALLATION section of this instruction.
The SEMS II distress alarm device 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 approximately once every three (3) seconds. The SEMS II
distress alarm is now in sensing mode.
Once activated, the SCOTT SEMS II 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
SEMS II 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.

WARNING
USERS OF RESPIRATORS EQUIPPED WITH
THE SEMS II DISTRESS ALARM MUST BE
AWARE OF THE PROPER OPERATION OF THE
DISTRESS ALARM. FAILURE TO RECOGNIZE
A MALFUNCTION OF THE SEMS II DISTRESS
ALARM AND TAKE PROPER CORRECTIVE
ACTION MAY RESULT IN SERIOUS INJURY OR
DEATH.
PRE ALARM:
If the respirator remains motionless for more than twenty (20) seconds, the SEMS II
distress alarm will automatically sound a pre-alarm
When the pre-alarm occurs, the green ashing light on the control console is replaced
by alternating bright red lights which ash approximately once a second and are
accompanied by an ascending/descending audible tone which increases in volume
during the pre-alarm cycle.
If the respirator user is not incapacitated or not in need of assistance, move the respi-
rator to reset the pre-alarm. When reset, the ashing red light will be replaced by the
ashing 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 re-
set the pre-alarm. Shaking the control console will not reset the SEMS II 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 SEMS II 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 alarm tone from the sensor module accompanied by
simultaneous ashing red signal lights on the control console. After an additional (10)
second delay, the unit will send a notication of PASS activation to the SEMS II Base
Station and 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. After the full alarm
has been silenced, the SEMS II distress alarm will remain activated in sensing mode
with the green light ashing once per second. As long as the respirator is pressurized,
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. The
manual alarm may be activated at any time, even when the respirator is not pressurized.
The manual alarm is indicated by a loud alarm tone from the sensor module accom-
panied by simultaneous ashing red signal lights on the control console. The unit will
immediately send a notication of PASS activation to the SEMS II Base Station and
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 manual alarm, press the reset button twice. After the alarm has
been silenced, the SEMS II distress alarm will remain activated in sensing 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 ashing red light can be turned on at any time
by pressing the manual alarm button on the control console.
TO TURN OFF THE SEMS II DISTRESS ALARM
When use of the respirator with the SEMS II 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, press the
reset button twice to turn off the distress alarm and close the regulator purge valve.
If there is no pressure in the system when the RESET button is pressed twice, the
unit will sound a quick two tone chirp to indicate that the alarm has been turned off.
If there is air pressure left in the system when the RESET button is pressed twice, the
sensor module will allow fteen (15) seconds to for the residual air to bleed from the
system. .A green light will ash and sensor will beep for fteen (15) seconds. Once
the air has completely bled from system, the unit will sound the quick two tone chirp
to indicate that the alarm has been turned off. If pressure remains in the respirator
after the fteen (15) seconds and/or the respirator cylinder valve remains open, alarm
sensor WILL NOT turn off and the distress alarm will return to sensing mode.

P/N 595289-01 Rev B 5/15
If the respirator cylinder is turned off and depressurized without rendering the alarm
sensor inactive (pressing the RESET button twice), the distress alarm will continue to
monitor motion in sensing mode. This means that the distress alarm may be used to
monitor motion after the respirator is turned off and depressurized. Resetting the full
alarm after the respirator has been depressurized will not turn off the distress alarm.
After resetting the full alarm, press the RESET switch twice with no alarm condition
to turn off the distress alarm.
LOW BATTERY
In a low battery condition, the SEMS II 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 SEMS II distress alarm will not emit the 3 beeps when
cylinder valve is activated.
While in low battery condition, the SEMS II 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
When the SEMS II PDA is in the off condition (cylinder valve closed with no ashing
lights, the batteries in the entire system can be checked by depressing and holding
the RESET button on the console.
• A GREEN LED will illuminate on the Control Console, if there is sufcient bat-
tery power remaining,
• A RED LED indicates that the batteries are low and must be replaced before
the respirator is to be used again.
If a low battery message occurs, ALL batteries must be changed before the respirator
is used again. See the BATTERY REPLACEMENT section of this instruction for details.

PROGRAMMING A UNIT WITH AN RFID TAG
SCOTT recommends re-programming with the RFID card in accordance with your
organization's procedures to assure that the user's unique ID number is in use at
all times. To program the identication of a SEMS II Portable unit with an RFID Tag,
proceed as follows:
1. Verify that the air cylinder is closed and there is no residual air in the system.
2. Verify that the electronics have been inactive for at lease thirty (30) seconds.
3. On the Control Console, hold down the GRAY (Withdraw) button until the ID light
goes on. Release the button.
4. Within ten (10) seconds, hold your SEMS II ID Tag against the back of the Control
Console labeled "SCAN ID TAGS HERE."
5. To indicate the programming has been successful, the ID light will ash three (3)
times slowly then go out.
6. When performing the REGULAR OPERATIONAL INSPECTION of the SEMS
II Accountability System, verify that the correct ID appears on the Base Station
display.
NOTE
ONCE THE RESPIRATOR HAS BEEN PRESSURIZED FOR USE, THE ID CANNOT
BE CHANGED. THE RESPIRATOR MUST BE SHUT DOWN AND THERE MUST
BE NO RESIDUAL AIR PRESSURE LEFT IN THE SYSTEM TO CHANGE THE ID.
To manually remove the programmed RFID card number, verify that the air cylinder is
closed, there is no residual air in the system, and the PASS is in the off state. Press
and hold the YELLOW RESET Button for eight (8) seconds. During reset, the red lights
on the PASS console will alternately ash and SEMS II Distress Alarm Pass device
will attempt to interface with Data Logger computer.
Additionally, the unit will automatically return to the default ID number:
– if the battery cover is opened and/or the batteries are removed,
OR
– after twenty-four (24) hours.

OPERATION AND USE OF PDA PORTABLE CONTROL
CONSOLE UNITS
Users of SCOTT respirators equipped with the SEMS II (and optional
BLUETOOTH enabled PDA) Control Consoles must be fully trained
in the operation of the equipment as part of a complete respiratory
protection program before entering a hazardous environment.
Start-up
• SEMS II: Use of the SEMS II enabled unit begins when the
user rst opens the cylinder valve on the respirator. The unit
will sound three chirps to indicate activation. After a brief start-
up sequence, the module will sound 3 quick audible chirps
and a green light located on the control console will ash
approximately once a second.
• BLUETOOTH:Use of the BLUETOOTH transmission begins
when a unit communicates with a previously paired compatible
portable two-way radio. Refer to the "PAIRING BLUETOOTH
ENABLED PDA CONTROL CONSOLE WITH PORTABLE
TWO-WAY RADIO" section of this instruction for pairing
instruction. To start the connection turn on the radio. Then,
open the cylinder. The LED light on the X3 console will begin
ashing BLUE as the PDA searches for the paired radio.
2. Initialization and RANGE
• SEMS II: After the start-up sequence, the SEMS II PDA Por-
table Unit will send an Initialization signal to the base station
a. When a SEMS II is searching for a connection to
the base station, the RANGE symbol on the Control
Console will flash YELLOW.
b. When a connection is made with the base station,
the RANGE symbol on the Control Console will turn
to solid GREEN
c. When a SEMS II respirator user loses contact with the base sta-
tion, the RANGE symbol on the Control Console will flash YELLOW
indicating out of range until it can regain contact. If using a dual
SEMS II and BLUETOOTH unit, the BLUETOOTH may connect
until SEMS II is back in range.
• BLUETOOTH:
a. When a Bluetooth connection is made to the two way radio the
LED on the PDA unit will light solid Blue.
b. When the SCBA user moves too far from the radio after logging-in,
the LED will flash BLUE until it is back in range.
Except for those functions which involve communication all PASS functions
of the Control Console and PDA distress alarm are still operational when the
Portable Unit is either out of range or not connected to a base station or radio.
3. PASS DISTRESS ALARM
a. The SEMS II PDA PASS distress alarm will operate in conjunc-
tion with the Portable Unit. If the distress alarm on the respirator
is activated, either by the user pressing and holding the Red
MANUAL ALARM button for at least two seconds, or from the user
being immobile for the required time duration, the Portable Unit
will send a PASS distress alarm signal to the base station. This
signal will override all other messages and actions of the Portable
Unit. The PASS symbol on the Control Console will flash RED.
(SEMS II and Bluetooth)
b. The PASS icon will appear Flashing RED on the Console, and an
audible alert will sound. (SEMS II and Bluetooth)
c. When the base station acknowledges the user’s distress signal
by selecting the TEAM Member's PASS button on the TEAM
Details, the PASS symbol on the Control Console will turn Solid
RED. (SEMS II ONLY)
d. The distress alarm on the respirator will continue until the user
shuts down the respirator or resets the alarm.

4. EVACUATION (SEMS II ONLY)
a. If the respirator users are required to leave the hazardous area,
the base station operator can send an evacuation message to the
Portable Units of logged-in respirator users. This message can be
sent either to all logged-in users (EVAC ALL), to everyone on an
Assignment (EVAC ASSIGN), to everyone in a geographic DIVISION
(EVAC BLDG) or to an individual logged-in users as selected from
the TEAM Details (EVAC).
b. The Portable Unit will emit the alert sound and the EVAC symbol will
begin flashing RED on the Control Console.
c. When an EVAC symbol begins flashing on the Control Console, the
respirator user must press twice the Yellow RESET button on the
Control Console to respond to the evacuation message. The EVAC
symbol on the Control Console will turn ON solid RED until the user
leaves the hazardous area and shuts down the respirator. The res-
pirator user's EVAC symbol in the TEAM Details on the Display will
change from RED to WHITE to indicate acknowledgement.
Evacuation message will ONLY be sent to individual SEMS II PDA users or to
the QUEUE interface. EVAC notice will not send to user while in BLUETOOTH
mode but will send once SEMS II communications have resumed. EVAC button
will be deactivated when no SEMS II Gateway is connected to the Base Station.
5. WITHDRAW
a. The respirator user may choose to leave the hazardous area. Pressing and
holding the Gray WITHDRAW button for at least two seconds will send that
message to the Base Station. The "EVAC" symbol on the Control Console
will ash YELLOW quickly as the WITHDRAW message appears on the Base
Station.
b. When the Base Station receives a user WITHDRAW message, the Base
Station Operator selects the ACK W/D button.
c) After the Base Station acknowledges, the “EVAC” symbol on the Control
Console will turn ON steady until user leaves hazardous area and shuts
down the respirator.
6. Air Supply Cylinder Pressure
a) In addition to the other end-of-service indicators on the respirator, when the
cylinder reaches one third of full pressure, the VIBE ALERT sounds a LOW
AIR warning with an audible alarm. .
b) The VIBE ALERT alarm will be transmitted until the respirator has been de-
pleted. This LOW AIR alarm is in addition to the other end-of-service indicators
on the respirator.
7. Shutdown
a) After leaving the hazardous area and conrming that respirator use is no
longer required, doff the respirator according the user instructions provided
with the respirator.
b) Close the cylinder valve. Use the purge valve to release all the residual air
pressure in the system.
c) Press the Yellow RESET button twice.
d) The Control Console will sound the alert tone. The SEMS II PDA Portable
Unit is now off.

PRIMARY FUNCTIONS OF THE SOFTWARE
IMPERIUM software is designed for both tactical and strategic event management
with compliance to NIMS and the user’s own organizational standard operating
guidelines (SOG’s).
The software is not SCBA specic and is designed to be used also by rst responders.
The primary purpose of the IMPERIUM is to monitor the activities of Accountability
System users, including active SEMS II PDA (Personal Distress Alarm) users and
Queue Accessory users, as well as Non-SEMS II PDA users (by use of RFID Tags to
log into the system) and Equipment.
The software is a TEAM Based approach to event management based on dened
ASSIGNMENTS and TEAMS placed on those assignments.
Each Event can be new or can be based on a customized set of parameters set in an
EVENT template. The Application Settings can also be preset to control the way the
Software displays and/or processes the information provided to the The IMPERIUM
Base Station Operator.
The primary functions of the software are as follows:
1. Open an EVENT.
2. Create ASSIGNMENTS for TEAMS.
3. ASSIGN Individual Resources to ASSIGNMENTS and TEAMS (and/or DIVISIONS
depending on the nature of the event.)
4. REJECT Individual Resources (active SEMS II PDA users, Bluetooth enabled
PDA users, NON-SEMS II PDA users and Equipment only.)
5. REMOVE Assignments, TEAMS, DIVISIONS, or Individuals from the event.
6. MONITOR the condition of active SEMS II and Bluetooth enabled PDA users and
take the appropriate actions.
7. Create NOTES for the event.
8. Provide a REPORT of the event.
Active SEMS II PDA users can send signals to and receive signals from the base
station. When in BLUETOOTH mode, PDA users can send signals to the base sta-
tion but cannot receive them from the base station. The base station operator can
perform the following tasks:
MONITOR ALERTS for:
• LOW AIR SUPPLY of each active SEMS II and BLUETOOTH enabled PDA user.
• PASS Activation (either automatic and manual activation) of each active SEMS
II and BLUETOOTH enabled PDA user.
• OUT-OF-RANGE – Shows the status of the communication link from each
User’s active SEMS II PDA (or QUEUE Interface) to the base station. (SEMS
II and QUEUE only)
• WITHDRAW Notication from each active SEMS II and BLUETOOTH enabled
PDA users.
Send an EVACUATION (EVAC) Signal when required (SEMS II PDA USERS ONLY):
• EVAC ALL – Evacuate all logged in active SEMS II only.
• EVAC TEAM – Evacuate a TEAM of logged in active SEMS II only.
• EVAC ASSIGNMENT– Evacuate by ASSIGNMENT of logged in active SEMS
II only.
• EVAC BLDG – Evacuate by DIVISION of logged in active SEMS II only.
• EVAC IND – Evacuate an Individual active SEMS II PDA users only.
NOTE
SEMS II PDA UNITS AND QUEUE ACCESSORIES CAN INITIALLY TAKE
APPROXIMATELY FORTY (40) SECONDS TO TWO (2) MINUTES TO CONNECT
TO THE BASE STATION. CONNECTION TIME MAY INCREASE AS THE NUMBER
OF ADDITIONAL NODES (EXTERNAL DEVICES) INCREASES.
NOTE
IF A PDA UNIT HAS BOTH SEMS II AND BLUETOOTH CAPABILITIES, THE SEMS
II WILL TRANSMISSIONS WILL ALWAYS TAKE PRECEDENCE AND APPEAR AS
A SEMS II USER ON THE BASE STATION. THE BLUETOOTH TRANSMISSION
WILL ONLY APPEAR AS A BLUETOOTH USER IF THE SEMS II TRANSMISSION
CANNOT CONNECT TO THE BASE STATION.

USE AS PART OF AN ACCOUNTABILITY SYSTEM
TRAINING REQUIRED BEFORE USE. Refer to the PAK-TRACKER Locator Sys-
tem User Instructions, SCOTT P/N 595102-01 for complete details on the use of the
PAK-TRACKER Locator System. Use of this equipment must be part of a complete
personnel accountability system that includes procedures for monitoring the deploy-
ment and condition of all users. Do not rely on the PAK-TRACKER Locator System
as the only technique for locating missing personnel. A Rapid Intervention or Rescue
team using the Hand Held Receiver must have a minimum of two (2) people. For their
own safety, the team members must pay attention to their surroundings at all times
while using the PAK-TRACKER Locator System.
The accountability system must include procedures for alerting the incident commander
and rescue teams when actuated transmitters or the missing personnel have been
found or when they have moved from their previous location. It is the responsibility of
the personnel accountability system to allow for such contingencies without exposing
individuals and teams to unnecessary dangers.
PRINCIPLES OF OPERATION
OF THE PAK-TRACKER LOCATOR SYSTEM
The SCOTT PAK-TRACKER locator system is an electronic system consisting of a
Hand Held Receiver and a Transmitter built into the SEMS II Sensor Module on the
SCBA backframe. The Transmitter is activated when the PASS is in Full Alarm. 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.
WARNING
READ AND UNDERSTAND THIS ENTIRE MAN-
UAL AND THE PAK-TRACKER LOCATOR
SYSTEM MANUAL, P/N 595102-01. TRAINING IS
REQUIRED BEFORE USE OF THIS EQUIPMENT
IN A HAZARDOUS SITUATION. THE TRAINING
MUST INCLUDE AN UNDERSTANDING OF THE
LIMITATIONS OF THE EQUIPMENT AND HOW TO
INTERPRET LOCATING INFORMATION, ALONG
WITH EXTENSIVE PRACTICE WITH THE SYSTEM
IN A VARIETY OF ENVIRONMENTS. USE OF THIS
EQUIPMENT MUST BE A PART OF A COMPLETE
PERSONNEL ACCOUNTABILITY SYSTEM.
ALWAYS UPDATE TRAINING WITH EACH NEW
PIECE OF EQUIPMENT. USE OF A PAK-TRACKER
LOCATOR SYSTEM WITHOUT PROPER TRAIN-
ING MAY PLACE THE USERS AT HIGHER RISK
IN DANGEROUS SITUATIONS WHICH COULD
RESULT IN SERIOUS INJURY OR DEATH.
MULTIPLE SIGNAL PATHS ARE POSSIBLE
OPERATION AND USE OF
THE SCOTT PAK-TRACKER LOCATOR SYSTEM

Page 19 of 36
P/N 595289-01 Rev B 5/15
WARNING
CONTINUED TRAINING AND PRACTICE IN A
VARIETY OF SITUATIONS IS ESSENTIAL TO
DEVELOPING THE SKILLS TO PROPERLY IN-
TERPRET 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.
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 transmitter.
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 Receiver,
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, SCOTT P/N 595102-01
for complete details on the use of the PAK-TRACKER Locator System.
When a SEMS II Control Console has been programmed with the user’s RFID Tag, the
PAK-TRACKER locator system will display the rst eight characters of the Employee ID
number as programmed on the RFID Tag. The rst eight (8) characters of the Employee
ID number on the RFID Tag must be unique to that individual. Use a badge number or
some other identier that is not shared by anyone else. Using a unique number in the
rst eight (8) characters will assure that searchers using the PAK-TRACKER locator
system will not see two signals with the same number displayed.
If the RFID Tag is not used, PAK-TRACKER locator system will display the default
eight digit ID number which appears on a label beside the cable connection on the
Sensor Module. This default number can be reprogrammed using the SCOTT Pak-
Link Computer Interface. Refer to the Pak-Link Computer Interface Installation and
Use Instructions, SCOTT P/N 595123-01, for complete details.
To return to the default ID number and remove the programmed RFID card number,
proceed as follows:
1. Verify that the air cylinder is closed and there is no residual air in the system.
2. Verify that the electronics have been inactive for at lease thirty (30) seconds.
3. Press and hold the YELLOW button on the Console for eight (8) seconds until
the red LEDS begin ashing alternately.
In addition, the unit will automatically return to the default ID number:
– if the battery cover is opened and/or the batteries are removed,
OR
– after twenty-four hours.
SCOTT recommends re-programming with the RFID card in accordance with your orga-
nization's procedures to assure that the user's unique ID number is in use at all times.
