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.
