[labnetwork] wet bench EMO's

[Matthew Moneck]

Hi Kyle,

Our wet decks (manufactured by JST) only shut off 208V and 120V power to
the units.  DI, N2, and CDA feeds remain active, which means DI and N2
spray guns remain active, as well as purges for the electronics enclosures,
spinners, etc.  We also have CO2 fire suppression systems on all decks with
flammable solvents.  Those systems are powered by a separate panel
connected to building emergency power and will also remain active after
activation of the EMO button on the wet deck.

Best Regards,

Matt
