REGULAR OPERATIONAL INSPECTION
When installed on a SCOTT SCBA, inspection and test of the SCOTT
SEMS PDA distress alarm is to be conducted along with inspection
and test of the respirator before each use. To do this, the REGULAR
OPERATIONAL INSPECTION procedures in your respirator instruc-
tions will require modification. The instructions below are to be added
to the instructions for REGULAR OPERATIONAL INSPECTION of your
respirator. If, during the inspection, any malfunction of the respirator
or the SEMS PDA distress alarm is noted remove the respirator from
service and tag for repair by authorized personnel.
REGULAR OPERATIONAL INSPECTION of the SEMS PDA Portable
unit installed on a SCOTT SCBA requires inspection of both the Dis-
tress Alarm (PASS) functionality and the Portable Unit interaction with
the SEMS PDR Base Station.
Before REGULAR OPERATIONAL INSPECTION, verify that the bat-
teries are fresh and properly installed. Batteries are located in two
locations on the SEMS PDA distress alarm Portable Unit. Each loca-
tion notifies separately when the batteries require replacement:
• As the batteries in the Sensor Module begin to approach the end
of their useful life, the Sensor Module will sound a chirp approxi-
mately every two seconds, the green lights on the control module
will go out.
• When the battery in the Control Console requires changing, “BATT”
will appear in the display.
In either condition the SEMS PDA distress alarm will continue to oper-
ate normally, going into pre-alarm after 20 seconds with no motion
and full alarm after 12 more seconds of no motion.
While in a low battery condition, the SEMS PDA distress alarm will
continue to operate for a period of time greater then the longest dura-
tion cylinder available for the respirator. However, the batteries must
be replaced before the respirator is used again. See BATTERY RE-
PLACEMENT section of these instructions.
BATTERY TEST
When the SEMS PDA distress alarm is in the off condition (cylinder
valve closed with no flashing green lights, the batteries in the Sensor
Module can be checked by depressing and holding the reset button
on the console.
A green LED will illuminate on the console to indicate sufficient battery
power remaining; a red light indicates that the batteries must be re-
placed before the respirator is to be used again.
WARNING
FOLLOW REGULAR OPERATIONAL INSPEC-
TION PROCEDURE EXACTLY. IF THE SEMS
PDA DISTRESS ALARM DOES NOT ACTU-
ATE, OR DOES NOT OPERATE AS DE-
SCRIBED OR IF ANY OTHER OPERATIONAL
MALFUNCTION IS NOTED, DO NOT USE THE
RESPIRATOR.
WARNING
IN SEVERAL OF THE INSPECTION PROCE-
DURES DESCRIBED A FULL ALARM WILL
BE OBSERVED. THE FULL ALARM CONDI-
TION INCLUDES AN AUDIBLE TONE THAT
CAN EXCEED 95 dBA AT 3 METERS (9.9 FT.).
IN ORDER TO PREVENT POSSIBLE HEAR-
ING DAMAGE DURING TEST, THE ALARM
SHOULD BE RESET IMMEDIATELY ON VERIFI-
CATION THAT
EMS
IS FUNCTIONING PROP-
ERLY. HEARING PROTECTION SHOULD BE
WORN IF PROLONGED EXPOSURE TO A
FULL ALARM CONDITION IS ANTICIPATED.
NOTE
IF THIS INSPECTION IS DONE IN DIRECT SUN-
LIGHT IT MAY BE HELPFUL TO SHADE THE
LENS ON THE CONTROL MODULE WITH YOUR
HAND TO BE SURE THE GREEN LIGHT IS
FLASHING.
CAUTION
THE PERFORMANCE PROPERTIES OF THE
SEMS PDA DISTRESS ALARM CANNOT BE
PROPERLY TESTED IN THE FIELD.
WARNING
FAILURE TO REPLACE THE BATTERIES AND/
OR CONTINUING WITH MULTIPLE USES OF
THE SEMS EQUIPMENT AFTER THE LOW
BATTERY CONDITION HAS BEEN INDI-
CATED MAY RESULT IN FAILURE OF THE
SEMS ACCOUNTABILITY SYSTEM DURING
USE WHICH COULD LEAD TO SERIOUS IN-
JURY OR DEATH.
