INTERSPIRO S9 - 4 Leakage and Function Test Procedures

26
When not pressurized, low battery in the BAC is indicated by ashing red LEDs and
sound beeps.
NOTE: IF THE BAC INDICATES LOW BATTERY WHEN NOT PRESSURIZED THERE COULD BE LESS THAN 2 HOURS
OPERATION LEFT.
4 LEAKAGE AND FUNCTION TEST
CAUTION! PRIOR TO AND AFTER USE, PERFORM A VISUAL INSPECTION OF ALL PLASTIC, RUBBER AND METAL
PARTS FOR DAMAGE. IF ANY DAMAGED PARTS ARE FOUND THE SCBA MUST BE TAKEN OUT OF SERVICE
AND REPAIRED ACCORDING TO THE S9 AND S9 INCURVE SERVICE MANUAL. REPAIRS ARE TO BE MADE BY
INTERSPIRO OR A HOLDER OF AN INTERSPIRO SERVICE CERTIFICATE.
1. Turn off the positive pressure. See section 1.3 for instructions.
2. Open the cylinder valve carefully.
3. Turn on the positive pressure (see section 1.3 for instructions). A strong ow of air
should be heard.
4. Turn off the positive pressure. See section 1.3 for instructions.
5. The BAC emits a sound and the BAC and DDU LEDs start to ash yellow
indicating PASS Sensing mode. The digital display activates.
6. Check that the PASS pre-alert and alarm modes are operational as described in
the section 6.2 and section 6.3.
WARNING! FAILURE TO ENSURE THAT THE PASS IS FULLY OPERATIONAL PRIOR TO USE MAY EXPOSE THE USER TO
SERIOUS INJURY OR LOSS OF LIFE. ALTHOUGH THE PASS MEETS ALL CURRENT NFPA SPECIFICATIONS, THERE IS
NO INHERENT GUARANTEE AGAINST PASS FAILURE. EVEN THE BEST PASS CANNOT COMPENSATE FOR ABUSE
OR THE LACK OF A PASS TRAINING AND MAINTENANCE PROGRAM.
LIMITATION! S9 AND S9 INCURVE THAT INCLUDE AN INTEGRATED PASS ARE ONLY APPROVED FOR USE AS AN
INTEGRATED SCBA/PASS SYSTEM. IF THE PASS IS NOT FULLY FUNCTIONAL THEN S9 AND S9 INCURVE MUST BE
REMOVED FROM SERVICE.
NOTE! ALTHOUGH PASS CAN BE CHECKED FOR PROPER OPERATION, MOST PERFORMANCE PROPERTIES OF THE
PASS CAN NOT BE TESTED BY THE END USER IN THE FIELD.
7. With the cylinder valve still open and the positive pressure turned off, check that
the cylinder pressure is indicated on the DDU and in the HUD.
8. Read the pressure on the mechanical pressure gauge.
9. Listen for leaks. If any leakage is detected repairs should be made by an
authorized service personnel and the test repeated.
NOTE: THE CYLINDER VALVE PRESSURE GAUGE, SHOULDER MOUNTED PRESSURE GAUGE, AND HUD MUST READ
FULL PRIOR TO USE. NFPA 1404 REQUIRES THAT AIR CYLINDERS OF ALL SCBA SHALL BE MAINTAINED AT NOT
LESS THAN 90 PERCENT OF THE RATED PRESSURE STAMPED ON THE CYLINDER.
