  1. SEMS Scott Electronic Management System

  2. Objectives • Know the primary functions of SEMS • Identify SEMS components • Demonstrate the operation of the SEMS PDA Portable Unit • Demonstrate the operation of the SEMS PDR Base Station

  3. SEMS Primary Functions • Personal Alert Safety System (PASS) • Firefighter Accountability • Track current SCBA air supplies • Monitor the status of firefighters using air packs • Electronic Communications • Transmit PASS alarm activation to Receiver • Transmit Withdrawal signal to Receiver • Transmit Evacuation signal to the SEMS console • Terminology does not match Zone 3 training • True meaning is ABANDONMENT

  4. SEMS Components • Scott NXG2 Air Pack • SEMS PDA Portable Unit (Console) • Computer Module • Located behind bottle • Controls all pack electronics to include the PASS • Battery Compartment • SEMS PDR Base Station

  5. SEMS PDA Portable Unit – Components • Analog Pressure Gauge • Digital read-out • Information Center • Yellow button • Reset/Acknowledge • Blue Button • Withdrawal transmission • Red button • Manual PASS activation

  6. SEMS PDR Base Station – Command Unit • SEMS Base Station • Command Center Power Switch • Turns on/off all electrical systems in the rear of the Battalion 81 • Computer Monitors • Touch Screen • Regular Screen The computer screen is only a visual aid. Commands can only be sent and received through the base station unit.

  7. SEMS PDR Base Station - Components • Power Button • Turns on/off Base Station • Menu Button • Contains 7 items • Clear Button • No on (Y/N) questions • Acknowledge Button • Yes on (Y/N) questions • Scroll Button • Scrolls up/down on base station display • EVAC Button • Transmits Abandonment signal to operating SCBA’s • Digital Display Window • Displays SEMS information • Alarm Light • Visual Alarm warning

  8. SEMS PDR Base Station - Components • Menu Items • Clear Reject List • Removes rejected packs from the database • Set Clock • Sets time/date on the base station • Request Logon • Forced request of Logon • Request PAR • Forced update of information • Identify Base Unit • Displays Base Station ID information • Set Display • Adjust the display on the base station • Clear up PU Database • Removes all active portable units from the database

  9. SEMS PDR Base Station – Computer Display Department ID Apparatus ID Seat Position Air Pressure Time Pack is On Pack Status Range Indicator

  10. Engine Officer #1 Officer’s Seat Driver #2 In the bracket nearest the driver’s side rear door Hydrantman #3 Seat behind the officer Nozzleman #4 Seat behind the driver Aid Car Officer #1 Pack should be located in the top bracket Driver #2 Should be located in the lower bracket SEMS Additional Information – PDU Location

  11. SEMS Operation – Startup PDR Base Station • Start-up • Press and hold the power button • Base station will initialize • takes approximately 10 seconds • Base station is ready to operate when the clock appears

  12. SEMS Operation – Startup PDA Portable Unit • Start-up • SEMS PDA Portable unit activates when SCBA is turned on • Unit will sound 3 chirps to indicate activation • Start-up sequence takes approximately 10 seconds • Console displays “<<<<“ until logged onto a base station • Console flashes a green light to show normal operation

  13. SEMS Operation – Initialization • SEMS PDU • Sends an initialization signal • Indicated by “<<<<“ flashing on the console • Once a Base station is found, console will display “<< “ • After Base Station Acknowledges the logon, the console display will be blank.

  14. SEMS Operation – Initialization • SEMS PDR • Receives PDU initialization signal • PDR Displays “Request Logon? (Y/N)” • Acknowledge PDU: • Press and Hold “ACK” to monitor • PDU unit will be logged on • PDR will display “Truck? (Y/N)” • ACK: Logon all units from that apparatus • Clear: Logon that specific unit only. • Press and Hold “CLEAR” to send a unit to the Reject List

  15. SEMS Operation –Range • SEMS PDU • Works within ½ mile line of sight of PDR base station • Move out of range, “RNGE” displays on the console • Low pressure audible alarm sounds to alert the user • Will automatically re-logon when unit is in range • SEMS PDR • Range displays on Base station indicating the unit that is out of range • Computer display – Range turns from green to red

  16. SEMS Operation – Air Cylinder Pressure • SEMS PDU • Press and hold yellow button to check pressure • Displayed to nearest 100 psig • At 2250 psig, Console displays, “½ Air” • At 1150 psig, Console displays, “Low Air” • Low Air signal is transmitted to PDR within 10 seconds • SEMS PDR • Monitors air pack cylinder pressures • Low Air signal warning • Must press and hold “ACK” to acknowledge the low pressure warning • Low Air is displayed on the monitor for that unit

  17. SEMS Operation –Distress Alarm (PASS) • SEMS PDU • Activation: • Manual: Press the Red button for 2 seconds • Automatic: No motion for 30 seconds • Transmits to the PDR 10 seconds after activation • “PASS” displays on the console when the base station operator acknowledges the signal • PASS continues to alarm until the user shuts off the respirator or resets the PASS devise • PASS alarm overrides all other transmissions

  18. SEMS Operation –Distress Alarm (PASS) • SEMS PDR • Receives distress alarm • Displays “PASS” on screen • Must press ACK to acknowledge PASS activation • Displays “FF DOWN” after acknowledgement • If transmission is reset, “RESET” is displayed • Press ACK to acknowledge the reset • Display returns to normal operation • PASS Alarm overrides all other alarms

  19. SEMS Operation –Withdrawal • SEMS PDU • Press and hold the blue button until an audible chirp is heard • Chirp indicates a transmission is sent • “W-D” displays on the console when the base station operator acknowledges the transmission • “W-D” is displayed until the console is reset or the respirator is shutdown.

  20. SEMS Operation –Withdrawal • SEMS PDR • Receives withdrawal signal • Display shows “Withdrawal” • Press ACK to acknowledge transmission • Display shows “Withdrawing” • If transmission is reset, “RESET” is displayed • Press ACK to acknowledge the reset • Display returns to normal operation

  21. SEMS Operation –Evacuation • SEMS PDU • Receives EVAC signal • “EVAC” displays on console • Alert tone sounds • Double Click yellow button to acknowledge EVAC signal • Audible chirp is heard when acknowledgment is sent • User must leave the IDLH atmosphere immediately • To reset unit, pack must be completely shutdown • Unit cannot be reset by using the reset button • PASS overrides EVAC • If reset, returns to EVAC signal
