dust monitor audible alarms
The audible alarms have been set on the following dust monitors:

LVEA location 4 (clean room over test stand area): 20 raw counts @ .3 micron, 20 raw counts @ .5 micron
LVEA location 15 (clean room over BSC 8): 20 raw counts @ .3 micron, 20 raw counts @ .5 micron
LAB location 1 (OSB optics lab): 2000 raw counts @ .3 micron, 800 raw counts @ .5 micron
LAB location 3 (OSB bake oven room): 2000 raw counts @ .3 micron, 800 raw counts @ .5 micron

At the current sampling period of 1 minute, these raw counts should be multiplied by 10 to get particles per cubic foot. These alarm settings correspond to the current major alarm values for the alarm handler in the control room.
