    keyword=VESDA alarm


    At 10:30pm the "Right Shield Hut VESDA" alarm went off. Lights for "ZONE" and "Filter"
    are flashing and the light for "Smoke Level" is one. Consulted Jack, he came in, checked
    the box, and here is what he suggested:

    Since none of the level lights on the left (labeled as "1, 2, 3, 4, 5...10" from bottom to
    top) is on, and the light "OK" below them is on, the smoke level is probablly OKay. But the
    smoker detector (or whatever has this "filter") needs to be serviced. Consult the run
    coordinator or Jack if there is an opportunistic access.

    Jack silenced the alarm so the owl shift workers can nap.

    PS the TO (from Hall B) said VESDA="Very Early Smoke Detection Apparatus", something
    the shift leader doesn't know.
