c. Upon activation of the System Integrity Alarm, the respirator user
must leave the hazardous area and shut down the respirator.
The System Integrity Alarm functions even when the SCBA is out of range or
not connected to a base station or radio.
6. WITHDRAW
a. The respirator user may choose to leave the hazardous area. Pressing
and holding the gray WITHDRAW button for at least two seconds will send
a withdraw request to the Base Station. The EVAC symbol on the Control
Console will ash yellow quickly.
b. When the Base Station acknowledges the withdraw request, the EVAC
symbol on the Control Console will turn on and remain on until the user
leaves hazardous area and shuts down the respirator.
7. Air Supply Cylinder Pressure
In addition to the other end-of-service indicators on the respirator, the
VIBRALERT on the regulator sounds a LOW AIR warning with an audible
alarm when the cylinder reaches one third of full pressure. The VIBRALERT
alarm will be transmitted until the respirator has been depleted.
8. Shutdown
a) After leaving the hazardous area and conrming that respirator use is no
longer required, doff the respirator according the user instructions provided
with the respirator.
b) Close the cylinder valve. Use the purge valve to release all the residual air
pressure in the system.
c) Press the yellow RESET button twice.
d) The PASS device will sound the alert tone. The SEMS II Pro Control
Console is now off.
WARNING
THE RESPIRATOR USER MUST IMMEDI-
ATELY LEAVE THE AREA REQUIRING RE-
SPIRATORY PROTECTION WHEN AN END-
OF-SERVICE INDICATOR ALARM ACTU-
ATES. ACTUATION OF AN END-OF-SER-
VICE INDICATOR ALARM WARNS THAT
APPROXIMATELY 1/3 OF FULL PRESSURE
REMAINS IN THE AIR SUPPLY CYLINDER
(APPROXIMATELY 2/3 OF THE TOTAL
AIR SUPPLY HAS BEEN USED). A DELAY
IN LEAVING THE AREA AFTER ALARM
ACTUATION MAY CAUSE DEPLETION OF
BREATHING AIR SUPPLY, WHICH COULD
RESULT IN SERIOUS INJURY OR DEATH.
BASE STATION OPERATION
The SEMS II Pro Base Station consists of Monitor installed in a Windows based
Personal Computer, preferably a laptop (not included). 3M recommends the use of
a laptop computer designed for rugged use.
Monitor must be operated by a fully trained individual as part of a complete incident
management system and respiratory protection program. The Base Station
Operator must have the ability to notify other personnel if an emergency situation
develops as displayed by the SEMS II Pro Wireless SCBA Telemetry System.
Active SEMS II Pro-equipped SCBA users can send signals to and receive signals
from the Base Station. The Base Station operator must monitor and respond to
any ACTIVE ALERTS in accordance with the organization’s event management
program. This may include issuing an ePAR or EVAC signal to an individual or to
the entire team.
• Monitor SEMS II Pro-equipped SCBA for the following ACTIVE ALERTS:
– Low Air Level or Mid Air Level - When the air supply cylinder reaches
predetermined pressure, a Mid or Low Air Level signal will transmit to the
Base Station, which will display the air level for that SCBA and sound an
audible alarm. For low air pressures, the end-of-service-time indicators
(EOSTI) will activate on the SCBA. (The Low Air Level alert cannot be
disabled using Monitor.)
– PASS Alarm Active (either automatic and manual activation) - When
a user's PASS has been activated, the PASS signal will be sent to the
Base Station, which will display "PASS Alarm Active" for that SCBA and
sound the PASS audible alarm. The alarms will continue until the PASS
device is turned off on the SCBA. (The PASS Alarm Active alert cannot
be disabled using Monitor.)
– Out of Range – Status of the communication link to the Base Station.
The Out of Range alert will begin after forty (40) seconds without a
signal from the SEMS II Pro-equipped SCBA to the Base Station. The
Base Station will display "Out of Range" for that SCBA and sound the
Out of Range caution audible alarm, indicating the system is trying to
re-link with the user. The Base Station operator must respond to the
user’s Out of Range signal in accordance with the organization’s event
management program.
WARNING
AUDIBLE ALARMS WILL SOUND FROM THE
BASE STATION ONLY IF THE FOLLOWING
CONDITIONS APPLY: 1) THE AUDIBLE ALARMS
ARE ENABLED WITHIN MONITOR, AND 2) THE
BASE STATION COMPUTER SPEAKERS ARE
TURNED ON. DISABLING THE ALARMS AND/
OR MUTING THE SPEAKERS WILL RENDER
THE BASE STATION ALARMS SILENT. THE
BASE STATION COMMANDER MUST NOT
DISABLE THE ALARMS OR MUTE THE BASE
STATION SPEAKERS DURING AN ACTIVE
EVENT. FAILURE TO MONITOR AND RESPOND
TO AN ACTIVE ALARM COULD LEAD TO
SERIOUS INJURY OR DEATH.
WARNING
THE SCOTT CONNECT MONITOR BASE STATION
SOFTWARE MUST BE MONITORED BY A FULLY
TRAINED INDIVIDUAL WITH THE ABILITY TO
DIRECT RESCUE OPERATIONS AT ALL TIMES
WHEN LOGGED-IN RESPIRATOR USERS MAY
BE IN A HAZARDOUS AREA. FAILURE TO
PROVIDE A PROPERLY TRAINED BASE STATION
OPERATOR MAY PERMIT A SITUATION TO
OCCUR, WHICH COULD RESULT IN SERIOUS
INJURY OR DEATH.
WARNING
THE SCOTT CONNECT MONITOR BASE STATION
SOFTWARE COMMUNICATES ONLY WITH
FIREFIGHTER RESOURCES (RESPIRATOR
USERS) USING A 3M SCOTT SCBA EQUIPPED
WITH SEMS II. OTHER FIREFIGHTER
RESOURCES WHO ARE NOT USING APROPERLY
EQUIPPED 3M SCOTT SCBA MAY BE ADDED
FOR ACCOUNTABILITY PURPOSES, BUT THEY
WILL NOT BE AUTOMATICALLY ACCESSIBLE
THROUGH THE COMMUNICATIONS FUNCTIONS
OF MONITOR. FAILURE TO RECOGNIZE THE
STATUS OF FIREFIGHTER RESOURCES MAY
RESULT IN SERIOUS INJURY OR DEATH.
WARNING
WHENEVER THE SYSTEM INTEGRITY ALARM
ACTIVATES, THE RESPIRATOR USER MUST
LEAVE THE AREA AND SHUT DOWN THE
RESPIRATOR. FAILING TO DO SO MAY PUT
THE USER AT RISK FOR SERIOUS INJURY OR
DEATH.
