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
