General Information

Introduction
The BeaconMedæs Manual Manifold is designed to
supply piped medical gas where continuity of supply
is desired, and where the gas is to be supplied from
high pressure gas cylinders. The manual manifold is
ideal for small installation with low flow demands.
The unit should be monitored from a close by location
for quick reaction times to manually changeover
the cylinder banks when empty. All individual
components conform to ISO and HTM requirements
to form a medical gas control panel to which
maximises safety requirements with a simplified
function.
See figure 1 and Table 1 for general arrangement,
figure 2 shows the schematic diagram.
The duty bank is determined by operating the cylinder
valves or optional high pressure bank valves is fitted.
The duty bank will run down until the pressure
drops below alarm switch parameters. The supply
will then be manually changed over to the standby
bank. A signal can be taken to a remote alarm from
the contact gauge to alert the requirement to change
cylinders. This cycle is then repeated to maintain
continuous supply.
CAUTION - Change empty cylinders as soon
as possible
The control panel is available as standard to suit two
main distribution system pressures, 4 bar and 7 bar.
See table 1 for list of critical components included
and optional extras supplied as bolt on kits.
