WARNING
USERS OF RESPIRATORS EQUIPPED WITH
THE SEMS II DISTRESS ALARM MUST BE
AWARE OF THE PROPER OPERATION OF THE
DISTRESS ALARM. FAILURE TO RECOGNIZE
A MALFUNCTION OF THE SEMS II DISTRESS
ALARM AND TAKE PROPER CORRECTIVE
ACTION MAY RESULT IN SERIOUS INJURY OR
DEATH.
PRE ALARM:
If the respirator remains motionless for more than twenty (20) seconds, the SEMS II
distress alarm 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 a second and are
accompanied by an ascending/descending audible tone which increases in volume
during the pre-alarm cycle.
If the respirator user is not incapacitated or not in need of assistance, move the respi-
rator to reset the pre-alarm. When reset, the flashing red light will be replaced by the
flashing green and the ascending/descending tone will stop.
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 re-
set the pre-alarm. Shaking the control console will not reset the SEMS II distress alarm .
To manually reset the pre-alarm, press and hold 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 SEMS II distress alarm will go into full alarm. This may indicate that the user is
incapacitated or in need of assistance and can not 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 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 full alarm condition, press the reset button
twice
. After the full alarm
has been silenced, the SEMS II distress alarm 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
distress alarm 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 accom-
panied by simultaneous flashing red signal lights on the control console. The unit will
immediately send a notification of PASS activation to the SEMS II 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 SEMS II distress alarm 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 SEMS II DISTRESS ALARM
When use of the respirator with the SEMS II distress alarm is no longer required,
close the cylinder 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 distress 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
to indicate that the alarm has been turned off. If pressure remains in the respirator
after the fifteen (15) seconds and/or the respirator cylinder valve remains open, alarm
sensor WILL NOT turn off and the distress alarm will return to sensing mode.
