The machne s ftted wth a warnng whstle and a vsual
ndcator (1)
These components act as oxygen supply falure devces and
consttute the prmary alarm system, powered only by the
resdual oxygen supply, as descrbed n secton 343
The system can be checked whenever the low pressure
oxygen system s frst pressursed by turnng on a cylnder or
connectng a ppelne

A formal test (ncludng the acton of the nternal gas cut-off
devce) s performed as follows
1 onnect oxygen, ntrous oxde and ar supples
2 Set the system swtch (2) to ON
3 Set a flow of 2 L/mn on all gases
4 Dsconnect the oxygen supply at the wall socket or close
the oxygen cylnder valve and check
a) That as the oxygen flow slows down, the whstle starts
to sound and contnues for at least 7 seconds
b) That the flow of ntrous oxde s cut off completely
before the oxygen flowmeter shows zero flow
c) That the vsual ndcator (1) turns red before the
oxygen flow s entrely stopped
d) Ar, f ftted, contnues to flow
e) Renstate the oxygen supply
heck that the flow of ntrous oxde s renstated, and
that the vsual ndcator (1) turns green agan
