FCC NOTICE
This equipment has been tested and found to comply with the re-
quirements of United States Federal Communications Commission,
Code of Federal Regulations, FCC title 47, part 90 Section 20, limita-
tion (27) and requirement Part 90.238 over frequency range 453.0375
to 465.6375 MHz, as well as FCC Section 1.1310 for Occupational/
Controlled Exposure limits.
If the SEMS Base Station or Portable Unit has been damaged, DO
NOT use this equipment. Maintenance or repair of this equipment
must only be performed by an authorized SCOTT service center.
Unauthorized service may void the manufacturers warranty and may
cause damage to the equipment. Use only Scott authorized accesso-
ries, cables, and power connectors. Consult the operating and ser-
vice manuals for instructions on battery replacement, battery mainte-
nance, and use of accessory cables.
RADIO FREQUENCY INTERFERENCE (RFI)
When any electronic device is adversely affected by radio waves, Ra-
dio Frequency Interference (RFI) is said to have occurred. All elec-
tronic devices like the SEMS PDA distress alarm may be subject to the
effects of RFI, most of which are temporary in nature. Users of the
SCOTT AIR-PAK SCBA with the integrated SEMS PDA 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 INTERFER-
ENCE on page 14). If RFI occurs to the SEMS PDA distress alarm, it
may be caused by transmissions from two-way radio base stations or
high-powered vehicle mounted radios or transmissions from hand-held
or personal radios where the radio antenna is touching or very close to
(less than 6 inches from) components of the SEMS PDA distress alarm.
INTRINSICALLY SAFE LISTING
The SEMS PDA distress alarm, when installed on a SCOTT respirator,
is listed as intrinsically safe in Class I Division 1 Groups A, B, C and D
hazardous locations by Entela Testing Laboratories. To maintain Intrin-
sic Safe Listing, the respirator with SEMS PDA distress alarm must be
inspected regularly per the following Regular Operational Inspection
procedures. SEMS PDA distress alarm components must not be tam-
pered with in any manner. Only batteries of the type indicated on the
Sensor Module label and in the Battery Replacement instructions may
be installed. The battery compartments must only be opened in an
area known to be free of flammable or explosive hazards.
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 minimum, 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 en-
tered a particular region of the hazardous area can be contacted indi-
vidually 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.
WARNING
RADIO FREQUENCY INTERFERENCE (RFI)
MAY CAUSE A MALFUNCTION OF THE SEMS
PDA DISTRESS ALARM. USERS OF RESPI-
RATORS EQUIPPED WITH THE SEMS PDA
DISTRESS ALARM MUST BE AWARE OF THE
PROPER OPERATION OF THE DISTRESS
ALARM. FAILURE TO RECOGNIZE A MAL-
FUNCTION OF THE SEMS PDA DISTRESS
ALARM AND TAKE PROPER CORRECTIVE
ACTION MAY RESULT IN SERIOUS IN-
JURY OR DEATH.
