INTRODUCTION
These instructions explain the operation and use of the main functions of the SEMS
II Pro Wireless SCBA Telemetry System (SEMS II Pro). 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 3M Scott Air-Pak X3 Pro SCBA equipped with the integrated SEMS II Pro.
Complete training in the use of the SEMS II Pro equipment is required before actual
use in a hazardous environment. If the equipment does not work as described
in these instructions, remove the equipment from service and tag it for repair by
authorized personnel.
SEMS II PRO OVERVIEW
The SEMS II Pro system is a wireless SCBA telemetry system that provides
monitoring of and communication between respirator users in a hazardous area
and an incident commander or other designated person outside the hazardous area
(at the Base Station).
The complete system consists of:
• PASS Device: A Personal Alert Safety System (PASS) device on a
compatible self-contained breathing apparatus (SCBA) such as the 3M
Scott Air-Pak X3 Pro SCBA1. Using the Sensor Module installed on the
respirator backframe, the PASS device monitors the motion of respirator
backframe and initiates visible and audible warnings when the user is
motionless for a short period of time or when manually activated by the
user.
• Pak-Tracker Locator System: A two-part electronic system consisting of a
radio transmitter and a Hand Held Receiver (HHR) to locate the transmitted
signal from an activated PASS device within 1100 feet.
• Sensor Module Assembly: Electronics control module for battery power,
audio (alarm tones), the Pak-Tracker radio transmitter, data logging,
wireless communications, and the motion sensor.
1 Installation of the PASS device is approved by the National Institute of Occupational Safety
and Health (NIOSH) on specic models of 3M Scott Fire & Safety SCBAs

WARNING
NO PERSONAL ALERT SAFETY SYSTEM,
RESPIRATOR OR COMBINATION OF PERSONAL
ALERT SAFETY SYSTEM AND RESPIRATOR,
BY THEMSELVES, CAN PROVIDE COMPLETE
PROTECTION IN DANGEROUS SITUATIONS.
FAILURE TO FOLLOW THE INSTRUCTIONS IN
THIS MANUAL AND THE REQUIREMENTS OF
AN ORGANIZED RESPIRATORY PROTECTION
PROGRAM MAY LEAD TO SITUATIONS THAT
COULD RESULT IN SERIOUS INJURY OR DEATH.
WARNING
USERS OF RESPIRATORS EQUIPPED WITH
A PASS DEVICE MUST BE AWARE OF THE
PROPER OPERATION OF THE PASS DEVICE.
IF THE GREEN LIGHT IS NOT FLASHING
NORMALLY, OR IF THE UNIT EXHIBITS ANY
OTHER SIGNS OF A MALFUNCTION WITHOUT
THE USER TAKING PROPER CORRECTIVE
ACTION, CIRCUMSTANCES THAT RESULT IN
SERIOUS INJURY OR DEATH MAY OCCUR.
WARNING
SEMS II PRO COMMUNICATES ONLY WITH
FIREFIGHTER RESOURCES (RESPIRATOR
USERS) USING A 3M SCOTT FIRE & SAFETY
SCBA EQUIPPED WITH THE SEMS II & SEMS
II PRO WIRELESS SCBA TELEMETRY SYSTEM
INTEGRATED INTO THE PASS DEVICE. OTHER
FIREFIGHTER RESOURCES WHO ARE NOT
USING A PROPERLY EQUIPPED 3M SCOTT
FIRE & SAFETY SCBA MAY BE ADDED FOR
ACCOUNTABILITY 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.
• SEMS II Pro Control Console: Shoulder console equipped with a wireless
transceiver for data communication between the SCBA user and the Base
Station. The console includes the following features:
–A mechanical air supply gauge
–PASS device activation and reset buttons
–Icons indicating air supply, activation of a PASS alarm, initiation of
commands by the user or the incident commander, and Base Station
and two-way radio connection status
• SEMS II Gateway: USB transceiver that receives data from up to a
maximum of 75 SCBAs with SEMS II and SEMS II Pro Control Consoles
for visualization and management using the Base Station software, Scott
Connect Monitor.
• Scott Connect Monitor Software System2: Base station software that
monitors the status of SCBA users, including air supply levels, PASS
activation, and evacuation calls.
• SEMS II Repeater: A stationary unit that provides continuity of the mesh
network created by SCBAs equipped with SEMS II and SEMS II Pro.
• Programmable ID Tags and programming equipment
SEMS II Pro-equipped SCBAs provide continuous limited two-way communication
between the SCBA respirator Control Console and the Scott Connect Monitor
software. When logged on, all the SEMS II Pro 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 readjusts to the
movement of the users.
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 requirements of an organized respiratory protection program is one of the many
safety precautions that should be taken to avoid personal injury or death.
SEMS II PRO COMPONENTS
SEMS II Pro, when added to a 3M Scott Fire & Safety SCBA, consists of a Sensor
Module assembly with a 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
PASS device requires six (6) AA batteries to operate the Sensor Module on the
backframe.
SEMS II PRO CONTROL CONSOLE
The SEMS II Pro Control Console is integrated
into the 3M Air-Pak X3 Pro 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 PASS device
intended to assist in locating a respirator user who
is incapacitated or in need of assistance.
The PASS device reaches FULL ALARM in 32
seconds. The Control Console has a set of status
lights, a dial air pressure gauge, and three control
buttons which can easily be pressed with gloved
hands. Power is supplied by batteries in
the battery compartment on the SCBA
backframe.

SCOTT CONNECT MONITOR SYSTEM SOFTWARE
SCOTT CONNECT MONITOR software (Monitor) is designed to provide incident
commanders or other responsible parties with critical, real-time information about
the 3M Scott Air-Pak X3 Pro SCBA in use on an emergency scene. The application
uses the mesh network created by the SEMS II and SEMS II Pro-equipped SCBAs
to receive and display air level and alarm information for all SCBA users on a
scene. The software enables bi-directional communication of acknowledgments
between the application and SCBA users.
Users of this system must be familiar with the capabilities and limitations of the
system. The system is intended to be used as an integral part of an emergency
event management system, which includes planned deployment of personnel.
NOTE
USE IN ACCORDANCE WITH NFPA 1500, "STANDARD ON FIRE DEPARTMENT
OCCUPATIONAL SAFETY AND HEALTH PROGRAM."
Using Monitor requires the following:
• 3M Scott Air-Pak X3 Pro SCBA equipped with SEMS II Pro.
• A personal Windows-based computer (not included) with Monitor installed.
3M recommends use of a laptop computer designed for rugged use.
• SEMS II Gateway with USB Interface, P/N 201088-03.
Monitor is intended to supplement, not replace, your standard operating procedures
for emergency incident management. The incident commander must maintain an
awareness and control of all reghter resources participating in the incident. This
software does NOT replace conventional two-way radio communications. This
software does NOT replace the minimum two person team approach to personnel
deployment.
When a respirator user opens the cylinder valve and begins use of a 3M Scott
Air-Pak X3 Pro SCBA equipped with SEMS II Pro, SEMS II Pro electronics will
automatically begin to operate. If Monitor is running at the Base Station when SCBA
use begins, the SCBA will attempt to connect to the Base Station. The Incident
Commanders from each re company are responsible for coordinating activities
with each other and to maintain accountability for all participating reghter
resources.
For more information, see the SCOTT CONNECT MONITOR RF PASS BASE
STATION SOFTWARE - Installation & Use Instructions (P/N 595355-01) or the
Scott Connect Monitor Quick Reference Guide available within the software
application for complete details of computer requirements and Base Station
software setup and use.
WARNING
AUDIBLE ALARMS WILL ONLY SOUND FROM
THE BASE STATION WHILE BASE STATION
COMPUTER SPEAKERS ARE TURNED ON.
MUTING THE SPEAKERS WILL RENDER THE
BASE STATION ALARMS SILENT. THE BASE
STATION COMMANDER MUST NOT MUTE
THE BASE STATION SPEAKERS DURING AN
ACTIVE EVENT. FAILURE TO MONITOR AND
RESPOND TO AN ACTIVE ALARM COULD LEAD
TO SERIOUS INJURY OR DEATH.
PAK-TRACKER LOCATOR SYSTEM
The 3M Scott Pak-Tracker Locator System (the Locator System) is a two-part
electronic system consisting of a radio transmitter integrated into the SEMS II Pro
Control Console and a directional, HHR used to locate the signal coming from the
transmitter.
The 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 HHR
unit. The HHR is then used as a directional receiver to assist in leading the rescue
team to the activated transmitter.
By pointing the HHR 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 Locator System as the only
technique for locating missing personnel.
Failure to use this equipment properly
may actually increase the time needed

PROPER OPERATION OF THE PASS DEVICE.
FAILURE TO RECOGNIZE A MALFUNCTION
OF THE PASS DEVICE AND TAKE PROPER
CORRECTIVE ACTION MAY RESULT IN SERIOUS
INJURY OR DEATH.
USING THE PASS DEVICE
ACTIVATION
Prepare the respirator for use according to the user instructions provided with
the respirator. Install the batteries in the PASS device according to the BATTERY
INSTALLATION section of this instruction.
The PASS 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 PASS device is
now in sensing mode.
Once activated, the PASS device 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 PASS
device 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 PASS device will remain activated until turned OFF according to these
instructions.

WARNING
USERS OF RESPIRATORS EQUIPPED WITH
A PASS DEVICE MUST BE AWARE OF THE
PROPER OPERATION OF THE PASS DEVICE.
FAILURE TO RECOGNIZE A MALFUNCTION
OF THE PASS DEVICE 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 PASS
device 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 per second
and are accompanied by an ascending/descending audible tone that increases 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 ashing red light is replaced by
the ashing green and the ascending/descending tone stops.
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 PASS
device.
To manually reset the pre-alarm, press 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 PASS device will go into full alarm. This may indicate that the user is
incapacitated or in need of assistance and cannot 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 Pro Base Station (Monitor) 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 PASS device 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 PASS device 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
accompanied by simultaneous ashing red signal lights on the Control Console.
The unit will immediately send a notication of PASS alarm activation to the SEMS
II Pro 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 PASS device 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 PASS DEVICE
When use of the respirator with the PASS device is no longer required, close the cyl-
inder 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 PASS 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

Page 9 of 28 P/N 595369-01 Rev B 07/19
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, the
alarm sensor WILL NOT turn off and the PASS device will return to sensing mode.
If the respirator cylinder is turned off and depressurized without rendering the alarm
sensor inactive (pressing the RESET button twice), the PASS device will continue to
monitor motion in sensing mode. This means that the PASS device 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 PASS device.
After resetting the full alarm, press the RESET switch twice with no alarm condition
to turn off the PASS device.
LOW BATTERY
In a low-battery condition, the PASS device 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 a low-battery condition, the PASS device will not emit the 3 beeps when cylinder
valve is activated.
While in a low-battery condition, the PASS device 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 PASS device 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
battery 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.
WARNING
DO NOT USE A RESPIRATOR IN A LOW-
BATTERY CONDITION. FAILURE TO REPLACE
THE BATTERIES AND/OR CONTINUING WITH
MULTIPLE USES OF THE RESPIRATOR AFTER
THE LOW-BATTERY CONDITION HAS BEEN
INDICATED BY THE PASS DEVICE MAY RESULT
IN FAILURE OF THE PASS DEVICE DURING
USE AND POSSIBLE INJURY OR DEATH OF
THE USER.
DATA LOGGING FEATURE
Respirators equipped with a PASS device are compliant with NFPA 1982, 2018
Edition. The PASS device includes on-board electronics which maintain a running
log of event data including start-up, shut-down, and PASS activation. The 3M Scott
Pak-Link Programmer (P/N 200672-01) and Congure are required to access the
information. Instructions for downloading the data log are included in the Instruction
Guide provided within Congure.
Downloading data from the SCBA will remove the programmed RFID card, tag, or
button ID number and the PAK-ID will automatically return to the default ID number.
WARNING
PROGRAMMING A PASS DEVICE USING A RFID
TAG, BADGE, OR BUTTON OVERWRITES THE
PAK-ID FOR 24 HOURS. IF THE SCBA IS USED
WITHIN 24 HOURS OF PROGRAMMING WITH
AN RFID TAG, BADGE, OR BUTTON, THE NEW
ID IS TRANSMITTED TO THE PAK-TRACKER AND
TO MONITOR. AFTER THAT TIME, THE PAK-ID
DEFAULTS TO THE ID SET USING CONFIGURE

PROGRAMMING A PASS DEVICE WITH AN RFID TAG
3M recommends re-programming the PASS device 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 PASS device 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 least 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 and then go out.
6. When performing the REGULAR OPERATIONAL INSPECTION of the SEMS II
Pro Wireless SCBA Telemetry 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, indicating that the PASS
device is in programming mode. Use Congure and the Pak-Link Programmer
to program the Pak-ID. For more information, see the Scott Connect Congure
Instruction Guide available within Congure.
The unit will automatically return to the default ID number in either of the following
situations:
– if the battery cover is opened and/or the batteries are removed
– after twenty-four (24) hours
PRESSING THE GRAY (WITHDRAW)
BUTTON
PROGRAMMING THE USER ID WITH THE RFID TAG
ID LIGHT WILL FLASH 3
TIMES SLOWLY TO INDICATE
SUCCESSFUL PROGRAM
WARNING
PROGRAMMING A PASS DEVICE USING A RFID
TAG, BADGE, OR BUTTON OVERWRITES THE
PAK-ID FOR 24 HOURS. IF THE SCBA IS USED
WITHIN 24 HOURS OF PROGRAMMING WITH
AN RFID TAG, BADGE, OR BUTTON, THE NEW
ID IS TRANSMITTED TO THE PAK-TRACKER AND
TO MONITOR. AFTER THAT TIME, THE PAK-ID
DEFAULTS TO THE ID SET USING CONFIGURE
AND THE PAK-LINK PROGRAMMER. IF NO ID
WAS SET, THEN THE ID DEFAULTS TO THE
FACTORY-SET ID.
WARNING
DO NOT USE AN RFID TAG READER THAT HAS
AN OUTPUT POWER GREATER THAN 6 WATTS
WHILE IN A FLAMMABLE ATMOSPHERE.

OPERATION AND USE OF SEMS II PRO CONSOLE UNITS
Users of 3M Scott Air-Pak X3 Pro SCBAs equipped with the SEMS
II Pro 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.
1. Start-up: Use of the SEMS II Pro-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 per second.
2. Initialization and RANGE: After the start-up sequence, the
PASS device will send an initialization signal to the Base
Station
a. When a SEMS II Pro-equipped SCBA 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 Pro-equipped SCBA loses contact with
the Base Station, the RANGE symbol on the Control
Console will flash yellow, indicating out of range until
it can regain contact. If out of range, the SCBA will
search for a Base Station until it re-establishes a con-
nection.
Except for those functions which involve communication,
all PASS functions of the SEMS II Pro Control Console are
still operational when the SCBA is either out of range or not
connected to a Base Station or radio.
3. PASS ALARM (PASS)
a. The PASS device will operate in conjunction with the SEMS II Pro
Control Console. If the PASS device on the respirator is activated,
either by the user pressing and holding the red MANUAL ALARM
button or due to the user being immobile for the required time dura-
tion, the SEMS II Pro Control Console will send a distress signal to
the Base Station. This signal will override all other messages and
actions of the Control Console. The PASS symbol on the Control
Console will flash red.
b. The PASS icon will flash red on the Control Console, and an audible
alert will sound.
c. When the Base Station acknowledges the user’s distress signal, the
PASS icon on the Control Console will turn solid red.
d. The PASS device on the respirator will continue to alarm until the
user shuts down the respirator or resets the alarm.
4. EVACUATION (EVAC)
a. If the respirator users are required to leave the hazardous area, the
Base Station operator can send an evacuation message to the SEMS
II Pro Control Consoles of logged-in respirator users. This message
can be sent to any or all logged-in users.
b. The Control Console will emit the alert sound and the EVAC icon will
begin flashing red on the Control Console.
c. When an EVAC symbol begins flashing on the Control Console, the
respirator user must press the yellow RESET button on the Control
Console twice to respond to the evacuation message. The EVAC
symbol on the Control Console will turn solid red until the user leaves
the hazardous area and shuts down the respirator.
Evacuation messages will be sent ONLY to individual SEMS II Pro-equipped
SCBAs.
5. System Integrity Alarm (EVAC)
a. If the temperature of the on-board electronics exceeds a threshold
(approximately 176° F), the System Integrity Alarm is activated.
b. The PASS device will emit an audible alert and the EVAC icon will
illuminate (solid red) on the Control Console. The alarm continues
until the temperature of the electronics drops below the threshold.

MAY RESULT IN SERIOUS INJURY OR DEATH.

Page 13 of 28 P/N 595369-01 Rev B 07/19
c. Upon activation of the System Integrity Alarm, the respirator user
must leave the hazardous area and shut down the respirator.
The System Integrity Alarm functions even when the SCBA is out of range or
not connected to a base station or radio.
6. 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
a withdraw request to the Base Station. The EVAC symbol on the Control
Console will ash yellow quickly.
b. When the Base Station acknowledges the withdraw request, the EVAC
symbol on the Control Console will turn on and remain on until the user
leaves hazardous area and shuts down the respirator.
7. Air Supply Cylinder Pressure
In addition to the other end-of-service indicators on the respirator, the
VIBRALERT on the regulator sounds a LOW AIR warning with an audible
alarm when the cylinder reaches one third of full pressure. The VIBRALERT
alarm will be transmitted until the respirator has been depleted.
8. 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 PASS device will sound the alert tone. The SEMS II Pro Control
Console is now off.
WARNING
THE RESPIRATOR USER MUST IMMEDI-
ATELY LEAVE THE AREA REQUIRING RE-
SPIRATORY PROTECTION WHEN AN END-
OF-SERVICE INDICATOR ALARM ACTU-
ATES. ACTUATION OF AN END-OF-SER-
VICE INDICATOR ALARM WARNS THAT
APPROXIMATELY 1/3 OF FULL PRESSURE
REMAINS IN THE AIR SUPPLY CYLINDER
(APPROXIMATELY 2/3 OF THE TOTAL
AIR SUPPLY HAS BEEN USED). A DELAY
IN LEAVING THE AREA AFTER ALARM
ACTUATION MAY CAUSE DEPLETION OF
BREATHING AIR SUPPLY, WHICH COULD
RESULT IN SERIOUS INJURY OR DEATH.
BASE STATION OPERATION
The SEMS II Pro Base Station consists of Monitor installed in a Windows based
Personal Computer, preferably a laptop (not included). 3M recommends the use of
a laptop computer designed for rugged use.
Monitor must be operated by a fully trained individual as part of a complete incident
management system and respiratory protection program. The Base Station
Operator must have the ability to notify other personnel if an emergency situation
develops as displayed by the SEMS II Pro Wireless SCBA Telemetry System.
Active SEMS II Pro-equipped SCBA users can send signals to and receive signals
from the Base Station. The Base Station operator must monitor and respond to
any ACTIVE ALERTS in accordance with the organization’s event management
program. This may include issuing an ePAR or EVAC signal to an individual or to
the entire team.
• Monitor SEMS II Pro-equipped SCBA for the following ACTIVE ALERTS:
– Low Air Level or Mid Air Level - When the air supply cylinder reaches
predetermined pressure, a Mid or Low Air Level signal will transmit to the
Base Station, which will display the air level for that SCBA and sound an
audible alarm. For low air pressures, the end-of-service-time indicators
(EOSTI) will activate on the SCBA. (The Low Air Level alert cannot be
disabled using Monitor.)
– PASS Alarm Active (either automatic and manual activation) - When
a user's PASS has been activated, the PASS signal will be sent to the
Base Station, which will display "PASS Alarm Active" for that SCBA and
sound the PASS audible alarm. The alarms will continue until the PASS
device is turned off on the SCBA. (The PASS Alarm Active alert cannot
be disabled using Monitor.)
– Out of Range – Status of the communication link to the Base Station.
The Out of Range alert will begin after forty (40) seconds without a
signal from the SEMS II Pro-equipped SCBA to the Base Station. The
Base Station will display "Out of Range" for that SCBA and sound the
Out of Range caution audible alarm, indicating the system is trying to
re-link with the user. The Base Station operator must respond to the
user’s Out of Range signal in accordance with the organization’s event
management program.
WARNING
AUDIBLE ALARMS WILL SOUND FROM THE
BASE STATION ONLY IF THE FOLLOWING
CONDITIONS APPLY: 1) THE AUDIBLE ALARMS
ARE ENABLED WITHIN MONITOR, AND 2) THE
BASE STATION COMPUTER SPEAKERS ARE
TURNED ON. DISABLING THE ALARMS AND/
OR MUTING THE SPEAKERS WILL RENDER
THE BASE STATION ALARMS SILENT. THE
BASE STATION COMMANDER MUST NOT
DISABLE THE ALARMS OR MUTE THE BASE
STATION SPEAKERS DURING AN ACTIVE
EVENT. FAILURE TO MONITOR AND RESPOND
TO AN ACTIVE ALARM COULD LEAD TO
SERIOUS INJURY OR DEATH.
WARNING
THE SCOTT CONNECT MONITOR BASE STATION
SOFTWARE MUST BE MONITORED BY A FULLY
TRAINED INDIVIDUAL WITH THE ABILITY TO
DIRECT RESCUE OPERATIONS AT ALL TIMES
WHEN LOGGED-IN RESPIRATOR USERS MAY
BE IN A HAZARDOUS AREA. FAILURE TO
PROVIDE A PROPERLY TRAINED BASE STATION
OPERATOR MAY PERMIT A SITUATION TO
OCCUR, WHICH COULD RESULT IN SERIOUS
INJURY OR DEATH.
WARNING
THE SCOTT CONNECT MONITOR BASE STATION
SOFTWARE COMMUNICATES ONLY WITH
FIREFIGHTER RESOURCES (RESPIRATOR
USERS) USING A 3M SCOTT SCBA EQUIPPED
WITH SEMS II. OTHER FIREFIGHTER
RESOURCES WHO ARE NOT USING APROPERLY
EQUIPPED 3M SCOTT SCBA MAY BE ADDED
FOR ACCOUNTABILITY PURPOSES, BUT THEY
WILL NOT BE AUTOMATICALLY ACCESSIBLE
THROUGH THE COMMUNICATIONS FUNCTIONS
OF MONITOR. FAILURE TO RECOGNIZE THE
STATUS OF FIREFIGHTER RESOURCES MAY
RESULT IN SERIOUS INJURY OR DEATH.
WARNING
WHENEVER THE SYSTEM INTEGRITY ALARM
ACTIVATES, THE RESPIRATOR USER MUST
LEAVE THE AREA AND SHUT DOWN THE
RESPIRATOR. FAILING TO DO SO MAY PUT
THE USER AT RISK FOR SERIOUS INJURY OR
DEATH.

Page 14 of 28
P/N 595369-01 Rev B 07/19
WARNING
DO NOT TAKE THE BASE STATION INTO A FIRE
OR INTO A POTENTIALLY FLAMMABLE OR EX-
PLOSIVE ATMOSPHERE. OPERATE THE BASE
STATION ONLY IN A SAFE AREA AWAY FROM
THE HAZARDOUS ATMOSPHERE WHERE THE
RESPIRATORS ARE BEING USED. USE OF THE
BASE STATION IN A POTENTIALLY FLAMMABLE
OR EXPLOSIVE ATMOSPHERE MAY CAUSE IG-
NITION OF THE ATMOSPHERE, WHICH COULD
RESULT IN SERIOUS INJURY OR DEATH.
– WITHDRAW Notication - A user chooses to WITHDRAW by pressing
the gray button on the SEMS II Pro Control Console on the SCBA. When
this occurs, the WITHDRAW request is sent to the Base Station, which
displays "Withdraw Requested" and sounds the WITHDRAW audible
alarm.
– System Integrity Alarm (EVAC) - When the temperature of the SCBA's
on-board electronics exceeds an established threshold (approximately
176° F), the SCBA displays the EVAC symbol in solid red on the Control
Console and transmits the message to the Base Station, which displays
"System Integrity Alarm" for that SCBA and sounds an audible alarm.
The EVAC symbol remains illuminated and the alarm continues to sound
until the temperature drops below the threshold.
• Send an ePAR (ID) signal to all active SEMS II Pro-equipped SCBA users
as needed for personnel accountability.
• Send an EVACUATION (EVAC) signal to all active SEMS II Pro-equipped
SCBA users when required.
• Support Personnel Accountability - The Base Station operator must
monitor and coordinate the activities of non-SEMS II Pro-equipped
SCBA users who have logged into the system by the use of RFID Tags in
accordance with the organization’s event management program.
NOTE
SEMS II PRO-EQUIPPED SCBA'S 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.
The EVAC/WITHDRAW, PASS, and RANGE icons that appear on the software
display are the same as the EVAC/WITHDRAW, PASS, and RANGE symbols that
appear on the SEMS II Pro Control Console display.
NOTE
ACCESSIBILITY TO SOME SETTINGS MAY BE LIMITED BY YOUR SYSTEM
ADMINISTRATOR TO MAINTAIN COMPLIANCE WITH APPLICABLE NATIONAL
STANDARDS OR ESTABLISHED INTERNAL PROCEDURES.

CAUTION
THE RESPIRATOR SYSTEM MUST NOT BE
PRESSURIZED WHEN BATTERIES ARE BEING
INSTALLED. DAMAGE TO THE ELECTRONIC
COMPONENTS MAY RESULT IF BATTERIES
ARE INSTALLED WHEN THE SYSTEM IS
PRESSURIZED.
A 3M Scott Air-Pak X3 Pro SCBA equipped with a PASS device require six (6) “AA”
cell batteries for operation. The six (6) batteries power the Heads-Up Display, the
PASS device, and the PAK-TRACKER Transmitter.
NOTE
THE UNIT WILL RETURN TO THE DEFAULT ID NUMBER IF THE BATTERY COVER
IS OPENED AND/OR THE BATTERIES ARE REMOVED. 3M 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.
The batteries should be replaced only by a trained operator in a clean area known
to be nonammable.
Replace batteries as follows:
1. Close the respirator cylinder valve. Open the regulator purge valve to let out
all the trapped air. Close the regulator purge valve. Press the reset button
twice. If there is air pressure left in the system, the green light will continue to
ash while a fteen-second beep sequence sounds from the Sensor Module as
the residual air bleeds from the system. As soon as the air has completely bled
from system, the unit sounds a quick two-tone chirp and the PASS DEVICE
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 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 WHEN THE SYSTEM IS PRESSURIZED.
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. Carefully remove
the cover and set aside.
4. Remove the used batteries 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.
Use six (6) each of one of the following 1.5 volt AA batteries:
–Duracell2Alkaline 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.

CHECK YOUR WORK!
BEFORE ASSEMBLING THE BATTERY COVER,
CHECK TO SEE THAT ALL BATTERIES ARE
FRESH, NEW BATTERIES OF ONE OF THE
TYPES LISTED AND THAT THEY HAVE BEEN
INSTALLED PROPERLY.
BE SURE SEALING
SURFACES ARE CLEAN
BEFORE REASSEMBLY
6. The battery cover must be installed so that it is water-tight after replacement.
Clean the sealing rib around battery compartment and sealing face of the cover
by wiping with a clean damp cloth to remove any dirt or foreign matter that
might prevent a proper seal. Check cover gasket for tears or cuts. If damage
is found, remove respirator from service and tag it 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 to 13-15 in-lbs torque.
8. To test the batteries, verify that the PASS device 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 sufcient 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 tag it for repair
by authorized personnel.
AFTER REPLACING THE BATTERIES, PERFORM A REGULAR OPERATIONAL
INSPECTION BEFORE RETURNING THE RESPIRATOR TO SERVICE.
CAUTION
