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, who fitted your alarm/s.
•UK Building Regulations require new homes to have 1 hard wired smoke alarm per floor and to be interlinked. During 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.
