Product Line Overview
The Powerex FirstCall™ fully-automatic medical gas
manifold delivers an uninterrupted supply of medical
gas to a facility from multiple liquid cryogenic portable
bulk vessels equally divided into two banks, plus an
emergency reserve cylinder bank for liquid manifolds.

displays bank pressure, primary/secondary bank
status, final line pressure, changeover set point,
alarm status, and emergency reserve bank status
• Ethernet connectivity using BACnet over IP
protocol to building management system –
standard
• Controlled via next generation PLC technology
• Final line pressure switch included
• Robust changeover design using dome-loaded
primary regulators controlled by dual solenoids
•
Robust piston-style final line regulator
• Built-in economizer circuit to capture NER gas
from the secondary bank
• Emergency reserve regulator, gauges, transducer,
pressure switch, and header inlet block, and pipe
nipple included as a pre-assembled unit
• Removable cabinet enclosure for improved
service access
• Single point vent connection
• Maintenance mode
• Push-button bank changeover
• ¾” source valve included
• NEMA 4 enclosure optional
• Heaters optional for Nitrous Oxide and Carbon
Dioxide
• Input power 110 VAC to 240 VAC, 50 to 60 Hz
PLC + HMI
Combination PLC+HMI monitors inputs from bank
and final line transducers (cylinder), as well as pressure
readings from transducers and signals from bank,
emergency reserve, and final line pressure switches.
The PLC controls bank changeover and generates alarm
signals based on input from the installed pressure
switches. Bank status and alarm status are both
displayed on high quality 7” LED HMI touchscreens.
Preprogramed standard settings are included with
all standard medical gasses. Alarm messages and
descriptions are fully customizable. Alarm and error
history is recorded in Alarm Summary. The unit is
capable of communicating with building monitoring
system via Ethernet connection using BACnet over IP.
