OPERATION AND MAINTENANCE INSTRUCTIONS SEMS™ SCOTT ELECTRONIC MANAGEMENT SYSTEM PDA–PERSONAL DISTRESS ALARM AND PDR–PERSONAL DISTRESS RECEIVER USER ACCOUNTABILITY SYSTEM AND PERSONAL DISTRESS ALARM FOR THE SCOTT AIR-PAK® 2.2 / 3.0 / 4.5 / FIFTY SELF-CONTAINED BREATHING APPARATUS WARNING THE SCOTT SEMS USER ACCOUNTABILITY SYSTEM IS INTENDED FOR USE WITH SCOTT SELF-CONTAINED BREATHING APPARATUS (SCBA) WHICH MAY SUPPORT HUMAN LIFE IN HAZARDOUS ATMOSPHERES.
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.
The SEMS PDA distress alarm warns the user when the air supply cylinder has reached 50% of its full capacity and also functions as an electronic end of service time indicator for the respirator by sounding an alarm when the air supply cylinder has been depleted to 25% of its full capacity. The Control Console digital display shows the approximate cylinder pressure.
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 PDA distress alarm may be subject to the effects of RFI. Radio transmissions from the antennas of radios including those used by fire fighters, police and other public safety related personnel may produce RFI in the SEMS PDA distress alarm.
If the SEMS PDA 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 and hold at least two seconds to activate the alarm. IF THE SYMPTOMS OF RFI OCCUR, THE RESPIRATOR USER MUST CHECK THE SEMS PDA DISTRESS ALARM TO VERIFY THAT IT IS FUNCTIONING PROPERLY.
FCC NOTICE This equipment has been tested and found to comply with the requirements of United States Federal Communications Commission, Code of Federal Regulations, FCC title 47, part 90 Section 20, limitation (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.
BASIC FUNCTIONS OF THE SEMS EQUIPMENT The SEMS equipment has two primary functions: · Personal Alert Safety System (PASS) Distress Alarm · Evacuation Signal 1. The PASS Distress Alarm is joined to the SEMS PDA distress alarm operation. The Portable Unit will send a signal to the Base Station when the SEMS PDA distress alarm goes into full alarm.
OPERATION OF THE SEMS PDA DISTRESS ALARM With proper batteries installed and a charged air cylinder, the SEMS PDA distress alarm (PASS) is automatically activated when the respirator is pressurized by opening the cylinder valve of the respirator. If batteries are completely discharged or have not been installed, there will be no light or sound indicating that the unit will not work at all. Activation is indicated by 3 quick audible chirps from the Sensor Module.
Once activated, the SCOTT SEMS PDA distress alarm will remain activated until: 1. The respirator air cylinder is turned off with the residual air pressure purged from the regulator AND 2. The reset button on the control module has been pressed twice. In the automatic mode the SCOTT SEMS PDA distress alarm constantly monitors motion of the respirator backframe. The motion sensor is located in the Sensor Module along with the audible alarm.
MANUAL ALARM: If the respirator user is in a situation where immediate assistance is required, the SEMS PDA distress alarm provides a manual alarm button, located on the front of the Control Console on the user’s right shoulder, shown in FIGURE 2. The manual alarm causes the Full Alarm signal to be given.
OTHER OPERATIONAL FEATURES END OF SERVICE TIME INDICATOR The SEMS PDA distress alarm also provides an electronic end of service time indicator and cylinder pressure display as follows: 1/2 full cylinder When the air supply cylinder has reached 1/2 full capacity, the audible signal will sound and the display will read “1/2 AIR” for 10 seconds.
USE OF THE SEMS PDA PORTABLE UNIT Users of SCOTT respirators equipped with the SEMS 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 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.
4. 5. 6. 7. 8. Distress Alarm a) If the user is in distress or becomes immobile, the SEMS PDA distress alarm will operate in conjunction with the Portable Unit. If the distress alarm is activated, either by the user pressing and holding the MANUAL ALARM 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.
USE OF THE SEMS BASE STATION The SEMS PDR Base Station must be properly programmed before field use. See SEMS Programming Guide SCOTT P/N 89506-01 for complete details of SEMS programming. The SEMS PDR Base Station requires batteries for operation. See the BATTERY REPLACEMENT section of this instruction. An optional external power supply is available. The SEMS PDR Base Station must be operated by a fully trained individual as part of a complete respiratory protection program.
2. Evacuation a) To send an evacuation message to all logged-in respirator users, the Base Station operator must press and hold the “EVAC” button on the Base Station and then choose “ALL-CALL” from the menu on the display. The “EVAC message will be sent to all logged-in respirator users.
EVENT LOG Software within the Base Station maintains a data record or EVENT LOG of each communication to or from the Base Station from the time it is powered for use unitl it is powered down. To acces and use the EVENT LOG, proceed as follows: BASE UNIT INTERFACE SETUP Plug the Base Unit Interface Cable into a COM port as instructed in the COMPUTER SETUP section the SEMS Programming Instructions SCOTT P/N 89506-01. 1.
5. The EVENT LOG file is a text (.txt) which may be viewed in either Microsoft Excel or Microsoft Word. The data is in columns separated (delimited) by commas. It may require some manipulation of the columns to facilitate reading as shown in FIGURE 6. The columns contain information as follows: Column 1 Event number Identification Column 2 Date of Event Column 3 Time of Event Column 4 Fire Company (blank if the PDA and the Base Unit have the same name.
REGULAR OPERATIONAL INSPECTION When installed on a SCOTT SCBA, inspection and test of the SCOTT SEMS PDA distress alarm is to be conducted along with inspection and test of the respirator before each use. To do this, the REGULAR OPERATIONAL INSPECTION procedures in your respirator instructions will require modification. The instructions below are to be added to the instructions for REGULAR OPERATIONAL INSPECTION of your respirator.
INSPECTION OF SEMS PDA DISTRESS ALARM 1. While performing the visual inspection of the respirator visually inspect all SEMS PDA distress alarm enclosures, lenses, and wire conduits for cracks, wear or other damage. If damage is noted, remove respirator from service and tag respirator for repair by qualified personnel. 2.
8. Check alarm reset: While in full alarm, fully depress reset button, release, and depress again. The SEMS PDA distress alarm shall reset to the automatic mode. The loud alarm shall stop and the red flashing lights shall be replaced by green flashing lights. 9.
