Pre Alarm; Full Alarm; Manual Alarm; To Turn Off The Pass Device - 3M SCOTT SEMS II PRO Operation And Maintenance Instructions

PRE ALARM

If the respirator remains motionless for more than twenty (20) seconds, the PASS
device will automatically sound a pre-alarm.
When the pre-alarm occurs, the green flashing light on the Control Console is
replaced by alternating bright red lights which flash approximately once per second
and are accompanied by an ascending/descending audible tone that increases in
volume during the pre-alarm cycle.
If the respirator user is not incapacitated or not in need of assistance, move the
respirator to reset the pre-alarm. When reset, the flashing red light is replaced by
the flashing green and the ascending/descending tone stops.
Remember that the motion sensor is in the Sensor Module on the respirator
backframe beneath the air cylinder. Actual movement of the respirator backframe is
required to reset the pre-alarm. Shaking the Control Console will not reset the PASS
device.
To manually reset the pre-alarm, press the reset button on the side of the Control
Console until three (3) quick audible chirps are heard and the red flashing light on
the Control Console is replaced by the green flashing light.

FULL ALARM

If the respirator remains motionless through the twelve (12) second pre-alarm
cycle, the PASS device will go into full alarm. This may indicate that the user is
incapacitated or in need of assistance and cannot move.
Full alarm is indicated by a loud alarm tone from the Sensor Module accompanied
by simultaneous flashing red signal lights on the Control Console. After an
additional (10) second delay, the unit will send a notification of PASS activation to
the SEMS II Pro Base Station (Monitor) and the Pak-Tracker Locator transmitter
in the unit will begin transmitting the unique ID number that can be received by the
Pak-Tracker Hand Held Unit.
To reset the full alarm condition, press the reset button twice. After the
full alarm has been silenced, the PASS device will remain activated in sensing
mode with the green light flashing once per second. As long as the respirator is
pressurized, there must be movement of the respirator at least every twenty (20)
seconds or the PASS device will again go into pre-alarm followed by full alarm as
described above.

MANUAL ALARM

If the respirator user requires immediate assistance, pressing the manual alarm
button located on the front of the Control Console will immediately sound the full
alarm. The manual alarm may be activated at any time, even when the respirator is
not pressurized.
The manual alarm is indicated by a loud alarm tone from the Sensor Module
accompanied by simultaneous flashing red signal lights on the Control Console.
The unit will immediately send a notification of PASS alarm activation to the SEMS
II Pro Base Station and the Pak-Tracker Locator transmitter in the unit will begin
transmitting the unique ID number that can be received by the Pak-Tracker Hand
Held Unit.
To reset the manual alarm, press the reset button twice. After the alarm has
been silenced, the PASS device will remain activated in sensing mode.
To turn the unit off, press the reset twice again while the unit is not in alarm mode.
Remember, the loud audible alarm and flashing red light can be turned on at any
time by pressing the manual alarm button on the Control Console.

TO TURN OFF THE PASS DEVICE

When use of the respirator with the PASS device is no longer required, close the cyl-
inder valve on the respirator and vent the residual air from the respirator system by
opening the regulator purge valve. After all the air flow stops, press the reset button
twice to turn off the PASS alarm and close the regulator purge valve.
If there is no pressure in the system when the RESET button is pressed twice, the
unit will sound a quick two-tone chirp to indicate that the alarm has been turned off.
If there is air pressure left in the system when the RESET button is pressed twice, the
Sensor Module will allow fifteen (15) seconds to for the residual air to bleed from the
system. A green light will flash and sensor will beep for fifteen (15) seconds. Once
the air has completely bled from system, the unit will sound the quick two-tone chirp
