I created a new group called BeamTube_Pressure in the vacuum alarm handler configuration file and added the following channels to it:

HVE-LX:X4_144BTORR
HVE-MX:X1_343BTORR
HVE-MX:X5_346BTORR
HVE-EX:X1_523BTORR
HVE-LY:Y4_124BTORR
HVE-MY:Y1_243BTORR
HVE-MY:Y5_246BTORR
HVE-EY:Y1_423BTORR

I committed the changes to subversion.
