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.
• 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 – tem-
porarily cover the unit with a plastic bag (during this time the alarm will not function).
Never paint the alarm.
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.

wiring if Green LED is illuminated, but alarm does not
appear to function. If no Green LED check consumer
unit. Alarm with still function on battery power, if bat-
tery is in serviceable state. <Red LED will blink about
once a minute to confirm>. Check via Test Button.
