(b) Wall Mounting.
When a ceiling position is not practical (for example on a
ceiling having exposed beams or joists, or built-in radiant
heating) put the top edge of your Smoke Alarm between 15
and 30 cm (6 and 12 inches) below the ceiling. Keep at least
15cm (6 inches) from corners. (see figure 4).
(c) On a sloping Ceiling.
In areas with sloping or peaked ceilings install your Smoke
Alarm 90 cm (3 feet) from the highest point measured
horizontally (see figure 5), because "dead air" at the apex may
prevent smoke from reaching the unit.
(d) Locations to Avoid.
Don't place your Smoke Alarm in any of the following areas:
• Bathrooms, kitchens, shower rooms, garages or other
rooms where the smoke alarm may be triggered by steam,
condensation, normal smoke or fumes. Keep at least 6
metres (20 feet) away from sources of smoke - wall
mounting if necessary.
• Attics or other places where extremes of temperature may
occur (below 4°C/34°F or above 40°C/104°F).
• Near a decorative object, door, light fitting, window
moulding etc., that may prevent smoke from entering the
Smoke Alarm.
• Surfaces that are normally warmer or colder than the rest
of the room (for example attic hatches, uninsulated exterior
walls etc). Temperature differences might stop smoke from
reaching the unit.
• Next to or directly above heaters or air conditioning vents,
windows, wall vents etc. that can change the direction of
airflow.
• In very high or awkward areas where it may be difficult to
reach the alarm (for testing, battery replacement etc).
(e) Nuisance/False Alarms.
If, when the alarm goes off, there is no sign of smoke heat or
noise to indicate that there is a fire, you should get your family
into a safe place, before you start investigating.
Check the house carefully in case there is a small fire
smouldering somewhere.
Check whether there is some source of smoke or fumes, for
example cooking fumes being drawn past the Smoke Alarm
by an extractor.
If there are frequent nuisance/false alarms it may be
necessary to re- locate the device away from the source of the
fumes.
The Silencer Smoke Alarm Ei100S is designed for more
difficult areas, as you can silence the alarm for 8 minutes. This
gives time for smoke or fumes to clear, (see page 10 for more
details).
