Protocol Alarm Station

5029 Protocol Alarm Station
The 5029 Series Protocol Alarm Station combines the safety and
features of a standard Protocol Station with the added security of
a remote alarm system. The Protocol Alarm Station will provide
an audio/visual warning when a cylinder is nearly depleted. The
alarm set point is easily field adjustable to provide the level of
security and notification required. A convenient side port allows
the addition of a diaphragm valve for purging when changing
cylinders.
The Protocol Alarm Station systems are available in 316 stainless
steel with a variety of gauge ranges (600 psig, 4,000 psig,
6,000 psig, and 10,000 psig). The system comes complete with
a Protocol Station, a 3-foot all stainless steel pigtail with armor Shown with
casing, pressure switch gauge and remote alarm/power supply optional PRS4022
in either 110 vac or 220 vac. It may be ordered separately or Regulator
attached to any high purity regulator. (see page E •248)
