WARNING
READ AND UNDERSTAND THIS COMPLETE INSTRUCTION MANUAL BEFORE USING A
RESPIRATOR EQUIPPED WITH A SEMS ACCOUNTABILITY SYSTEM. FAILURE TO USE THE
SEMS ACCOUNTABILITY SYSTEM IN ACCORDANCE WITH THESE INSTRUCTIONS MAY
LEAD TO CIRCUMSTANCES WHICH COULD RESULT IN SERIOUS INJURY OR DEATH.
DESCRIPTION
The SCOTT Electronic Management System (SEMS) provides a
method of communication between respirator users in a hazardous
area and a designated person outside of the hazardous area. The
SEMS equipment consists of individual Portable Units attached to the
SCOTT AIR-PAK models 2.2/3.0/4.5/
Fifty
self-contained breathing
apparatus (SCBA) and a Base Station which transmit and receive
specific information between the respirator users and the Base Sta-
tion operator. The specific information consists of user identification
and status as well as alerts for evacuation. Complete training in the
use of the SEMS equipment is required before actual use in a hazard-
ous environment.
The Portable Unit is integrated into the Scott AIR-PAK SCBA as a part
of the remote air pressure gauge which hangs over the right shoulder
of the respirator user. The Portable Unit also functions as the Control
Console for the PAK-ALERT EMS distress alarm personal alert safety
system (PASS) installed on the respirator backframe. The Portable
Unit has a set of status lights, a four character digital display, a dial air
pressure gauge, and three control buttons which can easily be pressed
with gloved hands. Power is supplied by batteries in both the Portable
Unit and in the PAK-ALERT EMS distress alarm battery compartment.
The Base Station is a compact battery operated device that can be
tripod mounted or carried by a strap. A digital display provides infor-
mation about status of the respirator users who are logged onto the
Base Station. Simple dedicated function buttons control the transmis-
sion and receipt of signals with the respirator users. The Base Station
can be easily interfaced with a computer for programming and ad-
vanced applications.
When a respirator user opens the cylinder valve and begins use of an
AIR-PAK SCBA equipped with the SEMS Portable Unit, the Portable
Unit will automatically begin to operate. If the Base Station is present
at time of entry, the Portable Unit must log-in with the Base Station
before entry into the hazardous area. Contact between the Portable
Unit and the Base Station will continue until the respirator user termi-
nates use of the SCBA.
Each installation of SEMS equipment operates as a distinct set of
Portable Units and Base Station that transmit and receive on a single
frequency. If another installation of SEMS equipment is used in the
same area, the operation of each group will remain discreet and sepa-
rate between Portable Units and Base Stations. The SEMS equipment
operates between 453.0375 and 465.6375 MHz on radio channels
defined in FCC Title 47 (Telecommunications) Part 90 section 20, Limi-
tation (27) and requirement Part 90.238. Programming of the Portable
Units and Base Station is essential and must be performed prior to
training and use. See SEMS Programming Guide, Scott P/N 89506-
01 for complete details of programming the SEMS equipment.
WARNING
NO PERSONAL ALERT SAFETY SYSTEM, RES-
PIRATOR OR COMBINATION OF PERSONAL
ALERT SAFETY SYSTEM AND RESPIRATOR,
BY THEMSELVES, CAN PROVIDE COMPLETE
PROTECTION IN FIRE SITUATIONS. HOWEVER,
USING AN ALARM AND A RESPIRATOR IN
ACCORDANCE WITH THE REQUIREMENTS
OF AN ORGANIZED RESPIRATORY PROTEC-
TION PROGRAM IS ONE OF THE MANY
SAFETY PRECAUTIONS WHICH SHOULD BE
TAKEN TO AVOID PERSONAL INJURY OR
DEATH.

BASIC FUNCTIONS OF THE SEMS EQUIPMENT
The SEMS equipment has two primary functions:
•Evacuation Signal
•Distress Signal
1. The Evacuation Signal is sent from the Base Station to the Por-
table Units. It can be handled one of two ways:
a) All-Call Signal: The Base Station will send a signal to all por-
table units logged on to it. When received, the Portable Unit
will display “EVAC” and sound an audible signal. Every respi-
rator user must acknowledge this signal by pressing
twice
the
RESET button on the Control Console. Display will continue to
read “EVAC” until user leaves hazardous area and shuts down
the respirator.
b) Selective Evacuation Alarm The Base Station will send a sig-
nal to only one individual unit logged on to it. When received,
the Portable Unit will display “EVAC” and sound an audible
alarm. The selected respirator user must acknowledge this sig-
nal by pressing
twice
the RESET button on the Control Console.
Display will continue to read “EVAC” until user leaves hazard-
ous area and shuts down the respirator.
2. The Distress Signal is joined to the PAK-ALERT EMS distress
alarm operation. The Portable Unit will send a signal to the Base
Station when the PAK-ALERT EMS distress alarm goes into full
alarm. Activation of the full alarm can be either by manual activa-
tion of the user or by automatic activation from lack of user
movement for the time period set on the PAK-ALERT distress
alarm. Once acknowledged by the Base Station operator, “PASS”
will appear on the Portable Unit display.
Other additional functions include:
1. The Contact Signal is an automatic signal sent by the Base Sta-
tion to every Portable Unit that is logged in to the Base Station.
Any respirator user who does not return an acknowledgment to
the Contact Signal within 120 seconds will be shown on the Base
Station as “OUT OF RANGE.”
2. Air supply cylinder levels are monitored by the Portable Unit and
the Base Station. The user can press and hold the RESET but-
ton at any time for a digital display of the remaining air supply
cylinder pressure. The approximate cylinder pressure is displayed.
The user receives a “½ AIR” warning in the display with an au-
dible alarm when the cylinder reaches one-half of full pressure.
The user also receives a “LOW AIR” warning in the display with
an audible alarm when the cylinder reaches one quarter of full
pressure. The “LOW AIR” warning is also transmitted to the Base
Station. The “LOW AIR” alarm will continue to operate until the
respirator is shut down.
3. Users can inform the Base Station that they are withdrawing
from the hazardous atmosphere by pressing and holding the
“WITHDRAW” button on the Portable Unit for at least two sec-
onds. The display will read “W–D” until the user leaves the
hazardous area and shuts down the respirator.

PROGRAMMING
Before SEMS equipment can be put into service, the Base Station
and each Portable Unit must be programmed to work with each other.
The amount and detail of the information programmed in will depend
on the requirements of the organization using the SEMS. At a mini-
mum, the equipment must be setup so that the Base Station will
recognize each Portable Unit in the group and associate an identity of
the respirator user with the Portable Unit. In this way, specific users
who have entered a particular region of the hazardous area can be
contacted individually to evacuate to a safe atmosphere. In addition, if
a Portable Unit transmits a DISTRESS SIGNAL, the Base Unit will
display the identity of the respirator user. See SEMS Programming
Guide, Scott P/N 89506-01 for complete details of programming the
SEMS equipment.
REGULAR OPERATIONAL INSPECTION
When installed on a Scott SCBA, inspection and test of the Scott
SEMS Portable Unit is to be conducted along with inspection and test
of the respirator and the PAK-ALERT EMS distress alarm before each
use. To do this, the REGULAR OPERATIONAL INSPECTION proce-
dures in your respirator instructions will require modification. The
instructions below are to be added to the instructions for REGULAR
OPERATIONAL INSPECTION of your respirator. If, during the inspec-
tion any malfunction of the respirator or the SEMS Portable Unit is
noted, remove the respirator from service and tag for repair by autho-
rized personnel.
1. While performing the visual inspection of the respirator inspect
all SEMS Portable Unit enclosures, lenses, and wire conduits
for cracks, wear or other damage. If damage is noted, remove
respirator from service and tag respirator for repair by qualified
personnel.
2. Check the operation of the PAK-ALERT EMS distress alarm in
accordance with the REGULAR OPERATIONAL INSPECTION
defined in the user instruction for the PAK-ALERT EMS distress
alarm installed on your SCBA. All standard function of the PAK-
ALERT EMS distress alarm must operate properly.
3. With an operating Base Station, verify that the SEMS Portable
Unit initializes and logs-in to the Base Station. When testing the
PAK-ALERT EMS alarms, verify that the Portable Unit and Base
Station are communicating with each other properly.
4. Verify that the batteries are properly installed and that there is no
“BATT” indication on the display.
5. Send an “EVAC’ signal to the Portable Unit and check the response.
Verify that both the ALL-CALL and the Selective Evacuation sig-
nals are properly received by the Portable Unit.
6. When testing the “LOW AIR” alarm operation, verify that the proper
signal is transmitted to the Base Station.
On a regular basis established by your respiratory protection program,
each SEMS Base Station must be inspected and tested for proper
operation. Each of the functions defined in the USE OF THE SEMS
BASE STATION section of this instruction must be checked and veri-
fied to be operating properly. If any malfunction is found, remove the
Base Station from service and tag for repair by authorized personnel.
WARNING
IF THE LOW BATTERY INDICATION OCCURS AT
ANY TIME DURING REGULAR OPERATIONAL
INSPECTION, DO NOT USE THE RESPIRATOR.
CHANGE ALL BATTERIES 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 SUC-
CESSFULLY PERFORMED. USE OF A RESPI-
RATOR WITH DEPLETED BATTERIES MAY
LEAD TO A FAILURE OF THE RESPIRATOR
WHICH COULD RESULT IN SERIOUS INJURY
OR DEATH.
WARNING

2. Initialization and Range
a) After the start-up sequence, the Portable Unit will send an Ini-
tialization signal to the Base Station to log in. The Base Station
will respond by showing “ACK” for the identity assigned to that
Portable Unit.
b) If the respirator user moves too far from the Base Station after
logging-in, the Portable Unit will begin to display “RNGE” indi-
cating out of range until the user moves back into the Base
Station field of operation (up to one-half mile line-of-sight).
c) If the Portable Unit is too far away from the Base Station at
start-up, or if the Base Station is not powered up, the Portable
Unit display will read “RNGE” right from start-up and not be
logged into the Base Station. The Portable Unit will continue
trying to log-in to a Base Station until one comes into range or
is powered up.
d) Except for those functions which involve communication with
the Base Station, all other functions of the Portable Unit and
PAK-ALERT EMS distress alarm are still operational when the
Portable Unit is either out of range or not logged into a Base
Station.
3. Air Supply Cylinder Pressure
a) To check the air supply cylinder pressure, the user must press
and hold the RESET button on the Portable Unit. The approxi-
mate pressure remaining in the cylinder will be shown in the
display as PSIG.
b) When the cylinder reaches one-half of full pressure, the alert
sound will occur and the Portable Unit will display “1/2 AIR” for
ten seconds.
c) When the cylinder reaches one-quarter of full pressure, the
alert sound will occur and the Portable Unit will display “LOW
AIR”. A low air signal will be sent to the Base Station within ten
seconds. This end of service time indicator (EOSTI) alarm can-
not be silenced by the user until the user leaves the hazardous
area and shuts down the respirator. The Base Station operator
must press “ACK” on the Base Station to acknowledge the
user’s low air signal.
4. Distress Alarm
a) If the user is in distress or becomes immobile, the PAK-ALERT
EMS distress alarm will operate in conjunction with the Por-
table Unit. If the distress alarm is activated, either by the user
pressing and holding the MANUAL ALARM for at least two
seconds, or from the user being immobile for the required time
duration, the Portable Unit will send a distress signal to the
Base Station. The distress alarm will override all other mes-
sages and actions of the Portable Unit.
b) When the Base Station acknowledges the user’s distress sig-
nal by pressing the “ACK” button on the Base Station, the
Portable Unit will respond by displaying “PASS” and continu-
ing to sound the distress alarm on the respirator. The distress
alarm will continue until the user shuts down the respirator.
WARNING
THE RESPIRATOR USER MUST IMMEDI-
ATELY LEAVE THE AREA REQUIRING
RESPIRATORY PROTECTION WHEN AN
END OF SERVICE INDICATOR ALARM
ACTUATES. ACTUATION OF AN END OF
SERVICE INDICATOR ALARM WARNS
THAT APPROXIMATELY 25% OF FULL
PRESSURE REMAINS IN THE AIR SUPPLY
CYLINDER (THAT IS, APPROXIMATELY
3/4 OF THE TOTAL AIR SUPPLY HAS
BEEN USED). A DELAY IN LEAVING THE
AREA AFTER ALARM ACTUATION MAY
RESULT IN SERIOUS INJURY OR
DEATH.

Unit until the user leaves the hazardous area and shuts down
the respirator.
6. Withdraw
a) The respirator user may choose to leave the hazardous area.
Pressing and holding the WITHDRAW button on the Portable
Unit will send that message to the Base Station.
b) When the Base Station receives a user withdrawal message,
the operator presses the “ACK” button on the Base Station to
respond.
c) When the Portable Unit receives the acknowledgment re-
sponse, the Portable Unit will display “W–D” until the respirator
user leaves the hazardous area and shuts down the respira-
tor.
7. Batteries
If the any of the batteries on the respirator needs replace-
ment, the equipment will indicate as follows:
– SENSOR MODULE – The PAK-ALERT EMS will sound a
single audible chirp from the sensor module once every 2 sec-
onds and the green light on the control module will not flash.
– CONTROL CONSOLE – "BATT" will appear in the display
but all other functions of the SEMS Portable Unit will operate
normally.
If any low battery condition appears at start-up, immediately
change the batteries before use of the respirator. If a low bat-
tery condition appears while the respirator is in use, the
equipment will continue to operate for a period of time greater
then the longest duration cylinder available for the respirator,
but the batteries must be changed before the next use of the
respirator. Refer to the battery changing instructions included
in the PAK-ALERT EMS distress alarm user instructions pro-
vided with your respirator.
