FAILURE TO CAREFULLY READ AND UNDERSTAND THE FOLLOWING INSTRUCTIONS MAY RESULT IN SERIOUS INJURY OR DEATH TO THE SCBA USER. USE OF A RESPIRATOR INTEGRATED WITH THE SEMS USER ACCOUNTABILITY SYSTEM WILL REQUIRE MODIFICATION OF THE RESPIRATOR "REGULAR OPERATIONAL INSPECTION PROCEDURES" AND WILL REQUIRE TRAINING OF THE RESPIRATOR USER IN THE USE OF SUCH RESPIRATORS. THE FOLLOWING INSTRUCTIONS SUPPLEMENT BUT DO NOT REPLACE THE OPERATING AND MAINTENANCE INSTRUCTIONS SUPPLIED WITH EACH RESPIRATOR. FIGURE 1 BASE STATION PORTABLE UNIT 2 DRAFT COPY 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. 3 DRAFT COPY 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.

FCC ID: PW9R8061 Report Number WS608900BPage 5 of 31 1.2SUMMARY The SEMS Portable Unit is a wireless device, operating in the frequency range of 453.0375MHz to 465.6375MHz and was supplied for Specific Absortion Rate (SAR) testing to the requirements of Supplement C (Edition 01-01) to OET Bulletin 65 (Edition 97-01). They were found to be compliant with requirements for Occupational/Controlled Exposure for Mobile/Portable devices. The Partial-Body SAR limit of 1g volume averaged SAR is stated as 8.0W/kg. SAR testing was performed using a Flat Phantom dimensions 300mmx300mmx200mm and 5.7mm thickness. The phantom was filled to a depth of 170mm with 450MHz Body simulant liquid. The dielectric properties were in accordance with the requirements for the dielectric properties specified in Supplement C (Edition 01-01) to OET Bulletin 65 (Edition 97-01). SAR testing was performed with the device affixed to the Portable of the unit, with the rear of the device facing toward the flat phantom. Testing was performed with the device being set to transmit at the top, middle and the bottom frequencies. Transmission at maximum power was enabled via the REDS 2 Service centre software provided by the client. The transmission mode selected was "Transmit Pre-amble". In this mode the carrier was frequency modulated with a 1.2 kHz tone that deviated the carrier nominally 1.5 kHz peak. This transmission mode was declared as being frequency modulated, and that the total transmitted power is the same as an un-modulated carrier transmission. A coarse scan of the whole device was performed to obtain the position giving maximum SAR. The scan parameters were redefined to perform a 3D scan to enable a volume averaged SAR reading to be obtained. The SEMS Portable Unit had a stub antenna, so that the requirement for testing with antenna extended and retracted was not applicable. The SEMS Portable Unit was only tested with the rear of the device against the flat phantom, as this was stated to be the simulated worst case normal mode of operation. No accessories were supplied with SEMS Portable Unit. Note: for Body worn operation, the SEMS Portable Unit has been tested and meet FCC RF exposure guidelines when used with an accessory which contains no metal and that the positions these device’s a minimum of 1.5mm from the body. Use of other accessories may not ensure compliance with FCC RF guidelines. Included in this report are descriptions of the te…

Both units are identical with respect to the RF parameters. The main differences are the power supply and the intended use for each device. Therefore, complete testing has been carried out on the base unit. Limited testing has been carried out on the mobile unit. Thus, radiated emissions have been carried out on both the mobile and base unit along with frequency stability under voltage variation to cover both power supply scenarios. A PC was supplied with the EUT to enable setting of the channels for testing purposes.
