SAFETY NOTE
In the United Kingdom,
ionisationsmoke detectorsare
subjectto the requirements of
the RadioactiveSubstances
Act 1993 and to the Ionising
Radiations Regulations1999
made under the provisions
of the Health and Safetyat
Work Act 1974.
Thedetectors,independently
tested by the National
RadiologicalProtection
Board(NRPB), conform toall
the requirementsspecified
in the ‘Recommendationsfor
ionisation smokedetectors in
implementationof radiation
standards’ publishedby the
NuclearEnergyAgency ofthe
Organisation for Economic
Co-operation and
Development (OECD)1977.
Thereis nolimitto the number
of ionisation smokedetectors
which may be installedin
any fire protectionsystem
within the UK. See
Certificate ofApproval No.
TA1 of 1999 issuesby the
HSE for further details.
Storage regulationsdepend
on local standardsand the
legislation,but, in the UK, the
numberof ionisationsmoke
detectorsin any buildingor
premisesshall beless than
500. See Certificateof
ApprovalNo. TA3 of1999
issuedby the HSE forfurther
details.
At the end of their
recommended workinglife
of ten years, ionisation
smoke detectorsshould be
returned to Apollofor safe
disposal or disposedof in an
otherwise locallyapproved
and environmentallysafe
manner. Pleasesee "A Guide
to the Care, Maintenance
and Servicing ofApollo
Products", PP2055.

For wind speeds up to 1m/s
(200ft/min) the change in
analogue value will not
exceed 5 counts.
Continuous operation in
wind speeds greater than
2m/s (400ft/min) is not
recommended. However,
wind speeds up to 10m/s
(2000ft/min)can be tolerated
for short periods and will
not under any conditions
increase the probability of
false alarms.
