    Default Scott PASS device failure

    Notice to the Fire Service:

    Over the past three months our department has been experiencing an issue with our SCBA and PASS devices which we feel should be a point of concern to others in the field. The breathing apparatus in question are Scott Air-Pak Fifty’s with the Pak-Alert 1000 integrated PASS device. The core of the problem we are having lies in the sudden and complete failure of the PASS device to arm or function. The units are failing without warning and there is no way to tell when or if they will be functional. During normal operation when air is introduced into the system the PASS device will chirp three times and be come active; our units have suddenly begun to not do so. More alarming is the fact that when there is air pressure in the system the PASS device CANNOT even be activated manually. The air system of the SCBA itself still functions normally and air supply to the wearer has not been known to be compromised, but the wear is left with no automatic or manual PASS device activation.

    Again, the SCBA in question is the Scott Air-Pak Fifty with the Pak-Alert 1000 Pass device. The units we are using were manufactured in March of 1998 and have had the circuit board upgrade issued from Scott in 2000.

    Good Luck and Stay Safe,

    Somewhere between genius and insanity!


    Not to be facetious, but...

    Have you changed the batteries for the PASS device?

    To answear your question the batteries have been changed every six months regardless of use and yes it was the first thing checked when the problems started to occur. Scott has been consulted about the problem and their position is that the devices are out of warranty and sometimes electronics that are this old just fail.
