PROGRAMMING
Before SEMS equipment can be put into service, the Base Station
and each Portable Unit must be programmed to work with each other.
The amount and detail of the information programmed in will depend
on the requirements of the organization using the SEMS. At a mini-
mum, the equipment must be setup so that the Base Station will
recognize each Portable Unit in the group and associate an identity of
the respirator user with the Portable Unit. In this way, specific users
who have entered a particular region of the hazardous area can be
contacted individually to evacuate to a safe atmosphere. In addition, if
a Portable Unit transmits a DISTRESS SIGNAL, the Base Unit will
display the identity of the respirator user. See SEMS Programming
Guide, Scott P/N 89506-01 for complete details of programming the
SEMS equipment.
REGULAR OPERATIONAL INSPECTION
When installed on a Scott SCBA, inspection and test of the Scott
SEMS Portable Unit is to be conducted along with inspection and test
of the respirator and the PAK-ALERT EMS distress alarm before each
use. To do this, the REGULAR OPERATIONAL INSPECTION proce-
dures in your respirator instructions will require modification. The
instructions below are to be added to the instructions for REGULAR
OPERATIONAL INSPECTION of your respirator. If, during the inspec-
tion any malfunction of the respirator or the SEMS Portable Unit is
noted, remove the respirator from service and tag for repair by autho-
rized personnel.
1. While performing the visual inspection of the respirator inspect
all SEMS Portable Unit enclosures, lenses, and wire conduits
for cracks, wear or other damage. If damage is noted, remove
respirator from service and tag respirator for repair by qualified
personnel.
2. Check the operation of the PAK-ALERT EMS distress alarm in
accordance with the REGULAR OPERATIONAL INSPECTION
defined in the user instruction for the PAK-ALERT EMS distress
alarm installed on your SCBA. All standard function of the PAK-
ALERT EMS distress alarm must operate properly.
3. With an operating Base Station, verify that the SEMS Portable
Unit initializes and logs-in to the Base Station. When testing the
PAK-ALERT EMS alarms, verify that the Portable Unit and Base
Station are communicating with each other properly.
4. Verify that the batteries are properly installed and that there is no
“BATT” indication on the display.
5. Send an “EVAC’ signal to the Portable Unit and check the response.
Verify that both the ALL-CALL and the Selective Evacuation sig-
nals are properly received by the Portable Unit.
6. When testing the “LOW AIR” alarm operation, verify that the proper
signal is transmitted to the Base Station.
On a regular basis established by your respiratory protection program,
each SEMS Base Station must be inspected and tested for proper
operation. Each of the functions defined in the USE OF THE SEMS
BASE STATION section of this instruction must be checked and veri-
fied to be operating properly. If any malfunction is found, remove the
Base Station from service and tag for repair by authorized personnel.
WARNING
IF THE LOW BATTERY INDICATION OCCURS AT
ANY TIME DURING REGULAR OPERATIONAL
INSPECTION, DO NOT USE THE RESPIRATOR.
CHANGE ALL BATTERIES IMMEDIATELY AND
REPEAT THE REGULAR OPERATIONAL TEST
OR TAKE THE RESPIRATOR OUT OF SERVICE
UNTIL THE BATTERIES ARE CHANGED AND
THE REGULAR OPERATIONAL TEST IS SUC-
CESSFULLY PERFORMED. USE OF A RESPI-
RATOR WITH DEPLETED BATTERIES MAY
LEAD TO A FAILURE OF THE RESPIRATOR
WHICH COULD RESULT IN SERIOUS INJURY
OR DEATH.
WARNING
FOLLOW REGULAR OPERATIONAL INSPEC-
TION PROCEDURE EXACTLY. IF THE SEMS
PORTABLE UNIT OR BASE STATION DOES
NOT OPERATE AS DESCRIBED OR IF ANY
OTHER OPERATIONAL MALFUNCTION IS
NOTED, DO NOT USE THE RESPIRATOR.
USE OF A MALFUNCTIONING RESPIRATOR
MAY RESULT IN SERIOUS INJURY OR
DEATH.
