5. Evacuation
a) If the respirator users are required to leave the hazardous area,
the Base Station operator can send an evacuation message to
the Portable Units of logged-in respirator users. This message
can be sent either to all logged-in users or to selected logged-
in users as chosen from the list on the Base Station.
b) The Portable Unit will emit the alert sound and “EVAC” will
appear flashing in the display.
c) When an “EVAC” message appears on the Portable Unit dis-
play, the respirator user must press twice the RESET button
on the Portable Unit to respond to the evacuation message.
“EVAC” will continue to appear in the display of the Portable
Unit until the user leaves the hazardous area and shuts down
the respirator.
6. Withdraw
a) The respirator user may choose to leave the hazardous area.
Pressing and holding the WITHDRAW button on the Portable
Unit will send that message to the Base Station.
b) When the Base Station receives a user withdrawal message,
the operator presses the “ACK” button on the Base Station to
respond.

sponse, the Portable Unit will display “W–D” until the respirator
user leaves the hazardous area and shuts down the respira-
tor.
7. Batteries
If the any of the batteries on the respirator needs replace-
ment, the equipment will indicate as follows:
– SENSOR MODULE – The PAK-ALERT EMS will sound a
single audible chirp from the sensor module once every 2 sec-
onds and the green light on the control module will not flash.
– CONTROL CONSOLE – "BATT" will appear in the display
but all other functions of the SEMS Portable Unit will operate
normally.
If any low battery condition appears at start-up, immediately
change the batteries before use of the respirator. If a low bat-
tery condition appears while the respirator is in use, the
equipment will continue to operate for a period of time greater
then the longest duration cylinder available for the respirator,
but the batteries must be changed before the next use of the
respirator. Refer to the battery changing instructions included
in the PAK-ALERT EMS distress alarm user instructions pro-
vided with your respirator.

tor use is no longer required, doff the respirator according the

the display. The Portable Unit is now off.

THE NEXT USE OF THE RESPIRATOR. USE OF
A RESPIRATOR WITH DEPLETED BATTERIES
MAY LEAD TO A FAILURE OF THE RESPIRA-
TOR WHICH COULD RESULT IN SERIOUS IN-
JURY OR DEATH.
