10. Useful Hints
•
Smoke/heat alarms can
only operate correctly if smoke particles/heat reach the
unit.
Correct selection/siting and installation are covered in the installers
manual.
•
Building Regulations
require new homes to have 1 hard wired smoke alarm per
floor and to be interlinked. From 2000 they will additionally require an interlinked
heat alarm to be fitted in most kitchens too. i.e. 3 alarms per property.
•
With the exception of garages/kitchens/bathrooms
it is recommended that
smoke alarms are fitted in every room
and outside all sleeping areas too.
A professional electrician should be employed for all mains powered (hard
wired) alarms.
•
If you are
redecorating
your home, paint fumes can contaminate the alarm –
temporarily
cover the unit with a plastic bag (during this time the alarm will not
function).
Never paint the alarm itself.
Only remove the bag when the paint is thoroughly dry.
•
If you
extend your property
, review your alarm requirements.
•
Smoke/heat alarms
should be replaced every 10 years
or sooner.
•
These products are designed for
domestically scaled premises.
