Medical Gas Supply System
Modular manifold headers for gas cylinders can be
connected to the Manifold Changeover System to
configure its gas supply capacity.
The Manifold Changeover System is connected to the
pipeline distribution system upstream of the emergency
supply, or downstream of the primary supply system
when used as backup. It can be isolated from the
pipeline distribution system by the lockable isolation
valve supplied. When used as a backup supply this valve
should be left open during normal operation, so the
unit will automatically supply the pipeline distribution
system with medical gas in the event of the primary
system failing to supply.
When used as a backup manifold system the line
pressure should be set slightly lower than the primary
supply pressure to prevent the unit from supplying gas
during normal operation of the primary supply system.

1
Stage Pressure Regulator.
st
For safe operation regarding performance, mechanical
strength, resistance to ignition in pure high pressure
oxygen supply and cleanliness, the device fully conforms
to BS EN ISO 10524-2. A pressure relief valve connected
to the regulator protects the downstream pressure and
is set a 2410 kPa (24.1 bar).
1.3
2
Stage Pressure Regulator.
nd
For safe operation regarding performance, mechanical
strength and cleanness the device fully conforms to BS
EN ISO 10524-2, the second stage pressure regulator is
a manually set diaphragm type and is used to set the
system pressure to suit typical nominal values for 4, 8
and 11 bar pipeline systems.
NOTE - To maximise performance each 2
pressure regulator is fitted with internal springs specific
to match the nominal line pressure.
1.4
Line Pressure Relief Valve.
The line pressure relief valves are preset to the values
shown in table 1 for the different line distribution
pressures.

The line pressure relief valve is fitted between the
pressure regulator and the isolation valve, thus
protecting the delivery system from over pressurisation
by discharging to atmosphere in the event of regulator
failure.

Modular Header for Cylinder
Connection.
The Medical Gas Supply System is compatible with
BeaconMedaes standard modular headers supplied up
to 2x6 cylinder connections, see table 2 for reference.
1.6
Halogen Free Components.
The Medical Gas Supply System contains NO
HALOGENATED polymers located in the gas stream that
may experience pressurised oxygen in excess of 3000
kPa (30 bar) in normal operation or single fault condition,
as recommended for safe practise of the medical gas
pipeline system.
