INTRINSICALLY SAFE LISTING
The SEMS II distress alarm with Integrated Locator transmitter, Model Number
200451-SERIES, when installed on a SCOTT respirator, is listed as intrinsically safe
per ANSI/UL Std. UL-913 in Class I, II, Division 1, Groups C, D, E, F, and G hazardous
locations by SGS U. S. TESTING COMPANY, Inc. Only when powered by the batteries
listed in this instruction or indicated on the label on the sensor module.
To maintain Intrinsic Safety Listing, inspect the respirator with SEMS II distress alarm
regularly per the Regular Operational Inspection procedures in this instruction. Sub-
stitution of Components May Impair Intrinsic Safety. To reduce the risk of ignition of
a ammable atmosphere, batteries must only be changed in an area known to be
nonammable. To reduce the risk of explosion, use only the approved batteries, do not
mix old batteries with unused batteries, or mix batteries from different manufacturers.
HAND HELD RECEIVER NON-INCENDIVE LISTING
The SCOTT PAK-TRACKER LOCATOR SYSTEM Hand Held Receiver P/N 200397-
02 is listed by SGS U. S. TESTING COMPANY, Inc. as Non-Incendive per ANSI/UL
Std. UL-1604 for use in Class I Division 2 Groups A, B, C, and D hazardous locations.
Temperature Code T4 (-25° C to 85° C). To maintain the Non-Incendive Listing, the
equipment must be inspected regularly per the following Regular Operational Inspec-
tion procedures. Do not tamper with or substitute components in any manner. Use
only SCOTT Battery Pack P/N 200402-02. Open the battery compartment only in an
area known to be free of ammable or explosive hazards.
WARNING – Substitution of Components May Impair the Non-Incendive Listing. To
reduce the risk of ignition of a ammable atmosphere, battery must only be changed in an
area known to be nonammable. Do not substitute any other battery or power source.
WARNING
IF THE SEMS II DISTRESS ALARM IS USED
IN AN AREA OF EXPLOSIVE OR FLAMMABLE
HAZARDS, FAILURE TO REGULARLY INSPECT
AS INSTRUCTED, FAILURE TO CORRECT
DAMAGE BEFORE USE, OR THE INSTALLATION
OF INCORRECT BATTERIES MAY LEAD TO A
FIRE OR EXPLOSION WHICH MAY RESULT IN
PERSONAL INJURY OR DEATH.
WARNING
FAILURE TO REGULARLY INSPECT THE HAND
HELD RECEIVER AS DESCRIBED IN THIS IN-
STRUCTION OR FAILURE TO CORRECT ANY
DAMAGE FOUND, MAY IMPAIR THE SAFETY
OF THE EQUIPMENT. THE INSTALLATION OF
INCORRECT BATTERY OR SUBSTITUTION
OF ANY OTHER COMPONENTS MAY IMPAIR
THE SAFETY OF THE EQUIPMENT. IF THE
EQUIPMENT IS USED IN AN EXPLOSIVE OR
FLAMMABLE ATMOSPHERE, IMPAIRING THE
SAFETY OF THE UNIT MAY LEAD TO A FIRE
OR AN EXPLOSION WHICH COULD RESULT IN
SERIOUS INJURY OR DEATH.
WARNING
REPLACE HAND HELD RECEIVER BATTERY
PACK ONLY WITH SCOTT BATTERY PACK,
PART NO. 200402-02. DO NOT REMOVE, RE-
CHARGE, OR REPLACE BATTERY PACK WHILE
THE DEVICE IS IN A HAZARDOUS LOCATION.
REMOVING, RE-CHARGING, OR REPLACING
THE BATTERY PACK WHILE THE DEVICE IS IN
A HAZARDOUS LOCATION MAY LEAD TO A FIRE
OR AN EXPLOSION WHICH COULD RESULT IN
SERIOUS INJURY OR DEATH.
WARNING
RADIO FREQUENCY INTERFERENCE (RFI)
MAY CAUSE A MALFUNCTION OF THE SEMS
II PERSONAL DISTRESS ALARM. USERS OF
RESPIRATORS EQUIPPED WITH THE SEMS
II PERSONAL DISTRESS ALARM MUST BE
AWARE OF THE PROPER OPERATION OF THE
DISTRESS ALARM. FAILURE TO RECOGNIZE
A MALFUNCTION OF THE EQUIPMENT AND
TAKE PROPER CORRECTIVE ACTION MAY
RESULT FAILURE OF THE SEMS II PERSONAL
DISTRESS ALARM AND LEAD TO SERIOUS IN-
JURY OR DEATH.
RADIO FREQUENCY INTERFERENCE (RFI)
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, most of which are temporary in
nature. Users of the SCOTT SCBA with the integrated SEMS II distress alarm must
be familiar with the normal operation of the distress alarm and must also be familiar
with how to identify and avoid the effects of RFI (see DETECTING AND AVOIDING
RADIO FREQUENCY INTERFERENCE on page 6). If RFI occurs to the SEMS II
distress alarm, it may be caused by transmissions from hand-held or personal radios
where the radio antenna is touching or very close to (less than 6 inches from) com-
ponents of the SEMS II distress alarm. It may also be caused by transmissions from
base stations or high-powered vehicle mounted radios or any other powerful source
of electromagnetic radiation.
WARNING
SUBSTITUTION OF COMPONENTS MAY IMPAIR
INTRINSIC SAFETY. TO REDUCE THE RISK OF
IGNITION OF A FLAMMABLE ATMOSPHERE,
BATTERIES MUST ONLY BE CHANGED IN AN
AREA KNOWN TO BE NONFLAMMABLE. TO
REDUCE THE RISK OF EXPLOSION, DO NOT
MIX OLD BATTERIES WITH UNUSED BATTER-
IES, OR MIX BATTERIES FROM DIFFERENT
MANUFACTURERS.
