SYSTEM DESCRIPTION
SEMS II ACCOUNTABILITY SYSTEM
The SCOTT Electronic Management System (SEMS II) is an accountability
system that provides three methods of communication between respirator
users in a hazardous area and an incident commander or other designated
person outside of the hazardous area. The SCOTT SEMS II Personal Distress
Alarm (PDA) is an optional accessory which is intended to be integrated only
with a compatible SCOTT self-contained breathing apparatus (SCBA) such
as the AIR-PAK® SCBA. The installation of the SCOTT SEMS II PDA distress
alarm is approved by the National Institute of Occupational Safety and Health
(NIOSH) on specic models of SCOTT SCBA.
The complete system provides three main functions:
• The SEMS II Personal Alert Safety System (PASS) on the SCBA to
sound a loud alarm when the user is motionless for a short period of
time;
• The SEMS II Accountability System with computer Base Station monitor-
ing of the assignment and status of up to 99 individual users, including
air supply levels, PASS activation, and evacuation calls;
• The PAK-TRACKER Locator System to locate the transmitted signal
from a SEMS II PDA Portable Unit where the PASS has been acti-
vated.
The complete SEMS II Accountability System equipment consists of:
• Individual SEMS II PDA Portable Units with Control Console attached
to the SCOTT self-contained breathing apparatus;
• A SEMS II Personal Distress Receiver (PDR) Base Station (the Base
Station PCMCIA Card and the SCOTT SEMS II Accountability System
Software installed in a Personal Computer);
• Programmable ID Tags and programming equipment;
• A PAK-TRACKER Hand Held Receiver for search and rescue.
The PDA Portable Units can transmit and receive specic information between
the respirator users and the Base Station operator. The specic information
consists of user identication and status as well as alerts for evacuation.
Complete training in the use of the SEMS II equipment is required before
actual use in a hazardous environment.
When logged on, all the SEMS II PDA Portable Units communicate to the
Base Station both directly and through other logged on units forming a com-
munications "mesh" to the Base Station. This extends the range for the units
furthest away from the Base Station.
No personal alert safety system, respirator, or combination of personal alert
safety system and respirator, by themselves, can provide complete protec-
tion in dangerous situations. However, using an alarm and a respirator in
acordance with the requirements of an organized respiratory protection pro-
gram 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
SCOTT SEMS II Accountability 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.

SEMS II PDR BASE STATION
The SEMS II PDR Base Station consists of a SEMS II Accountability System
Base Station PCMCIA Card installed in a Windows® based Personal Com-
puter, preferably a laptop (not included). SCOTT recommends use of a laptop
computer designed for rugged use.
With the SEMS II Accountability Software running on the PC, the incident
commander has current information about status of the respirator users who
are logged onto the Base Station, including information about air supply lev-
els and PASS activation. Simple dedicated functions in the software control
the transmission and receipt of signals with the respirator users. The same
computer can be used for programming the ID Tags used with the SEMS II
PDA distress alarm.

operates the PERSONAL ALERT SAFETY
SYSTEM (PASS) distress alarm intended
to assist 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 pressure gauge,
and three control buttons which can easily
be pressed with gloved hands. Power is
supplied by batteries in the SEMS II PDA
distress alarm battery compartment on the
SCBA backframe. FIGURE 1

Programming of the ID Tags and Portable Units allows the organization to
customize the identication of the SEMS II Portable Units. See SEMS II Pro-
gramming Guide, SCOTT P/N 595177-01 for complete details of programming
the SEMS II equipment.
SYSTEM DESCRIPTION CONTINUED...
When a respirator user opens the cylinder valve and begins use of a SCOTT
SCBA equipped with the SEMS II PDA, the Portable Unit will automatically
begin to operate. If the SEMS II PDR Base Station is present at time of en-
try, the SEMS II PDA must log-in with the Base Station before entry into the
hazardous area. The Base Station will then continue to monitor the SEMS
II PDA Portable Unit while it is in range until the respirator user terminates
use of the SCBA.

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. If another installation of
SEMS II equipment is used in the same area, the operation of each group can
remain discreet and separate between Portable Units and Base Stations.
The SCOTT SEMS II PDA distress alarm Portable Unit, when added to a
SCOTT SCBA respirator, as shown in FIGURE 1, 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 in the Sensor
Module on the backframe.

PAK-TRACKER LOCATOR SYSTEM
The SCOTT PAK-TRACKER Locator System is a two part electronic sys-
tem 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 missing personnel. Failure to use this equipment prop-
erly 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 Health and 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 BATTERY
INSTALLATION section of this instruction.
With proper batteries and a charged air cylinder installed, 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 a second. See FIGURE 4. The SEMS II distress alarm is now in the
automatic mode.
In the automatic mode, the SCOTT SEMS II distress alarm constantly moni-
tors 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.
The SCOTT SEMS II distress alarm will remain activated in the automatic
mode until turned OFF according to these instructions.

OPERATION OF THE SEMS II DISTRESS ALARM
CONTINUED ON NEXT PAGE...
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 a bright red light which ashes approximately once a second and
is 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 respirator 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 back-
frame is required to reset 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, almost continuous 3 tone chirp from the
sensor module accompanied by the ashing red signal light on the control
console. The unit will also send a notication of PASS activation to the SEMS
II Base Station that will appear on the computer display. In addition, 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. See FIGURE
4.
After the full alarm has been silenced by pressing the reset button twice, the
SEMS II distress alarm will remain activated in the automatic 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. See FIGURE 4. The manual alarm may be activated at any
time, even when the respirator is not pressurized.
If the manual alarm is activated when the respirator is not pressurized, press
the reset button twice to silence the alarm. The SEMS II distress alarm will
remain on in automatic mode. To turn the unit off, press the reset twice again
while the unit is not in alarm mode.
Remember, the loud audible alarm and ashing red light can be turned on at
any time by pressing the manual alarm button on the control console.

OPERATION AND USE OF THE SEMS II DISTRESS ALARM
CONTINUED...
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, close the regulator purge valve and press the reset button
twice to turn off the SEMS II distress alarm. If there is air pressure left in the
system, the green ashing light will continue to ash while a fteen second
beep sequence is heard from the sensor module as the residual air bleeds
from the system. As soon as the air has completely bled from system, the
unit will sound a quick two tone chirp and the PASS DEVICE distress alarm
will be inactive. If there is no pressure in the system when the RESET button
is pressed twice, there will be no fteen second beep sequence. When the
unit sounds a quick two tone chirp, the SEMS II distress alarm is inactive. If
there is any air pressure left in the system, the PASS DEVICE distress alarm
will return to the active mode.
If the respirator cylinder valve is open and/or pressure remains in the respi-
rator, the SEMS II distress alarm can not be turned off. Pressing the reset
button when the respirator is pressurized will only reset an alarm condition
and return the SEMS II distress alarm to automatic mode.
If the respirator cylinder is turned off and depressurized without pressing the
reset button twice, the SEMS II distress alarm will continue to monitor mo-
tion in automatic mode. This means that the SEMS II 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 SEMS II distress alarm. Press the reset switch twice with no alarm
condition to turn off the SEMS II distress alarm (there will be no fteen (15)
second beep sequence and two tone chirp will be heard).

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.
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 avail-
able for the respirator. However, the batteries must be replaced before the
respirator is used again. See the BATTERY REPLACEMENT section of these
instructions.
If batteries are completely discharged or have not been installed, there will
be no light or sound and the unit will not operate.
BATTERY TEST
When the SEMS II PDA distress alarm 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 BAT-
TERIES AND/OR CONTINUING WITH MULTIPLE
USES OF THE RESPIRATOR AFTER THE LOW
BATTERY CONDITION HAS BEEN INDICATED
BY THE SEMS II DISTRESS ALARM MAY RESULT

USER ACCOUNTABILITY FUNCTIONS
From the User's standpoint, the primary accountability functions of
the SEMS II equipment are Personal Alert Safety System (PASS)
Distress Alarm, the EVACUATION Signal, and the WITHDRAW
Signal.
1. When the PASS Distress Alarm is activated to full alarm, the SEMS II
PDA Portable Unit will send a signal to the Base Station. Activation of
the full alarm can be either by manual activation of the user pressing the
RED Manual Alarm Button, or by automatic activation from lack of user
movement. The PASS symbol will ash RED quickly. When the Base
Station operator acknowledges the message, the PASS symbol will ash
RED slowly.
2. The EVACUATION Signal is sent from the Base Station to the SEMS II
PDA Portable Unit. It can be handled one of two ways:
a) All-Call Signal: The Base Station will send a signal to all SEMS II PDA
Portable Units logged on to it. When received, the Control Console
will sound an audible signal and the “EVAC” symbol will ash RED
quickly. Every respirator user must acknowledge this signal by pressing
twice the yellow RESET button on the Control Console. After the Base
Station acknowledges, the “EVAC” symbol will remain ashing slowly
until user leaves hazardous area and shuts down the respirator.
b) Selective Evacuation Alarm: The Base Station will send a signal to only
selected units logged on to it. When received, the Control Console will
sound an audible signal and the “EVAC” symbol will ash RED quickly.
The selected respirator user must acknowledge this signal by pressing
twice the yellow RESET button on the Control Console. After the Base
Station acknowledges, the “EVAC” symbol will remain ashing slowly
until user leaves hazardous area and shuts down the respirator.
3. The user selects the WITHDRAW Signal to inform the Base Station that
the user is withdrawing from the hazardous atmosphere. The user presses
and holds the blue “WITHDRAW” button on the Control Console for at
least two seconds. The "EVAC" icon on the console will ash YELLOW
quickly and the WITHDRAW message appears on the Base Station. After
the Base Station acknowledges, the “EVAC” symbol will remain ashing
slowly until user leaves hazardous area and shuts down the respirator.
4. The RANGE symbol lights as follows:
YELLOW flashing slowly-
The PDA Unit is ON but the base station has not accepted it.
GREEN flashing once every 10 seconds-
The PDA Unit is logged onto base station and has been accepted.
The PDA Unit must be able to communicate with the Base Station
at least once a minute to remain IN RANGE.
YELLOW flashing fast-
The PDA Unit is OUT OF RANGE of the base station.
5. End-of-Service Indicators
In addition to the other end-of-service indicators on the respirator, the
air supply cylinder levels are monitored by the SEMS II PDA Unit and
transmitted to the Base Station. When the cylinder reaches one quarter
of full pressure, the Console sounds a “LOW AIR” warning with an audible
alarm as well as transmitting a “LOW AIR” warning to the Base Station.
The “LOW AIR” alarm will continue to operate until the respirator is shut
down.

USE OF THE SEMS II PDA PORTABLE UNIT
Users of SCOTT respirators equipped with the SEMS II PDA Portable
Unit 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
a. Use of the SEMS II PDA Portable Unit begins when the user opens the
cylinder valve on the respirator to start respirator usage. The unit will
sound three chirps to indicate activation.
b. After a brief start-up sequence, the GREEN SIGNAL Light on the Con-
trol Console will light. An alert tone, a “BE-doop” to indicate the system
activity, is used for several functions. Whenever the alert tone occurs,
the user should look at the Portable Unit display for information.
2. Initialization and RANGE
a. After the start-up sequence, the SEMS II PDA Portable Unit will send an
Initialization signal to the Base Station to log in. The Base Station will
respond by ACCEPTING the identity assigned to that Portable Unit.
b. If the respirator user moves too far from the Base Station after logging-
in, the RANGE icon on the Control Console will ash indicating out of
range until the user moves back into the Base Station eld 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 RANGE icon on the Control
Console display will light immediately from start-up and not be logged
into the Base Station. The SEMS II PDA Portable Unit will continue try-
ing 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 Control Console and SEMS II PDA
distress alarm are still operational when the Portable Unit is either out
of range or not logged into a Base Station.

a. If the user is in distress or becomes immobile, the SEMS II PDA PASS
distress alarm will operate in conjunction with the Portable Unit. If the
distress alarm 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 distress signal to the Base Station. The distress alarm will override
all other messages and actions of the Portable Unit. The PASS icon
will ash RED quickly.
b. When the Base Station acknowledges the user’s distress signal by
selecting the “ACK PASS” button on the Base Station, the PASS icon
on the Control Console will ash slowly while continuing to sound the
distress alarm on the respirator. The distress alarm will continue until
the user shuts down the respirator.
4. EVACUATION
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 or to selected logged-in users as chosen from the
list on the Base Station.
b. The Portable Unit will emit the alert sound and the EVAC icon will begin
ashing on the Control Console.
c. When an EVAC icon begins ashing on the Control Console, the res-
pirator user must press twice the Yellow RESET button on the Control
Console to respond to the evacuation message. The EVAC icon will
continue to ash at a slower rate until the user leaves the hazardous
area and shuts down the respirator.
5. WITHDRAW
a. The respirator user may choose to leave the hazardous area. Pressing
and holding the Blue WITHDRAW button for at least two seconds will
send that message to the Base Station. The "EVAC" icon on the Con-
trol Console will ash YELLOW quickly as the WITHDRAW message
appears on the Base Station.

USE AS PART OF AN ACCOUNTABILITY SYSTEM
TRAINING REQUIRED BEFORE USE. 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. 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 missing
personnel. A Rapid Intervention or Rescue team using the Hand Held Re-
ceiver 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 unneces-
sary dangers.
PRINCIPLES OF OPERATION
OF THE PAK-TRACKER LOCATOR SYSTEM
The SCOTT PAK-TRACKER locator system is an electronic system consist-
ing 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 A PART OF A COMPLETE
PERSONNEL ACCOUNTABILITY SYSTEM. AL-
WAYS 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.

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 Re-
ceiver,
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.

DETECTING AND AVOIDING
RADIO FREQUENCY INTERFERENCE
When any electronic device is adversely affected by radio waves, Radio
Frequency Interference (RFI) is said to have occurred. All electronic devices
like the SEMS II distress alarm may be subject to the effects of RFI. Radio
transmissions from the antennas of radios including those used by re ght-
ers, police and other public safety related personnel may produce RFI in the
SEMS II distress alarm. RFI may occur while the radio is transmitting if the
respirator equipped with the SEMS II distress alarm is in close proximity to
a base station or high-powered vehicle mounted radio, or if the antenna of
a personal portable hand held radio is touching or within six (6) inches of
the Control Console or Sensor Module of the SEMS II distress alarm. See
FIGURE 5.
Be aware of the symptoms of RFI. A SEMS II distress alarm affected by RFI
may temporarily give false indications such as the sudden sounding of the
loud continuous three-tone chirp of the full alarm. In some instances the
lights on the control console may ash without sounding the alarm. In rare
circumstances, an alarm which was sounding may stop.
If the PAK-ALERT exhibits any of the symptoms of RFI, identify the source
of the RFI and do the following:
– If the symptoms of RFI occur when standing near a base station trans-
mitting antenna or a truck mounted radio antenna, move away from the
antenna until the symptoms stop.
– If the symptoms of RFI occur while transmitting on a hand-held radio,
move the radio away from the PAK-ALERT .
CHECK THE CONTROL CONSOLE AND BE CERTAIN THE GREEN LIGHT
IS FLASHING NORMALLY WHEN THE INTERFERENCE STOPS, REGARD-
LESS OF THE SOURCE.
In normal usage with the air cylinder open, the SEMS II distress alarm will
typically resume normal operation after experiencing RFI.
Page 35 of 40 P/N 595166-01 Rev A 1/09
DRAFT COPY
If the SEMS II distress alarm is affected by RFI when the respirator air supply
is turned off or the cylinder is empty, the distress alarm could be turned off
during use. If this occurs, depress the RED Manual Alarm Button to activate
the alarm.
IF THE SYMPTOMS OF RFI OCCUR, THE RESPIRATOR USER MUST
CHECK THE SEMS II DISTRESS ALARM TO VERIFY THAT IT IS FUNC-
TIONING PROPERLY. IF THE GREEN LIGHT ON THE CONTROL CONSOLE
DOES NOT RESUME FLASHING IN THE NORMAL MANNER AFTER EX-
PERIENCING THE SYMPTOMS OF RFI, OR IF THE UNIT CONTINUES
TO MALFUNCTION IN ANY OTHER WAY, PROCEED TO A SAFE AREA,
REMOVE THE RESPIRATOR FROM SERVICE AND TAG FOR REPAIR BY
AUTHORIZED PERSONNEL.
Minimize or eliminate the effects of RFI by protecting the PAK-ALERT with
the following steps:
– Maintain a safe distance from a base station transmitting antenna or a
truck mounted radio antenna.
– Keep the antennas of hand held radios at least six (6) inches away from the
CONTROL CONSOLE or the SENSOR MODULE. See FIGURE 5.
RFI AND THE PAK-TRACKER HAND HELD RECEIVER
If the Hand Held Receiver experiences RFI, it may be necessary to remove
the Hand Held Receiver from service. In a known safe, non-hazardous
area, remove and reinstall the batteries to reset the unit (see the BATTERY
REPLACEMENT section of the PAK-TRACKER Locator System User
Instructions, SCOTT P/N 595102-01). Then inspect and return the Hand Held
Receiver to service.
