Note: Ceiling mounting is recommended - do not wall mount alarms.
Sloping Ceiling
In areas with sloping or peaked ceilings install the alarm 900mm from the highest point measured horizontally (see Figure 2). This is because “dead air” at the apex may prevent smoke from reaching the unit.
4.1 Locations To Avoid
DON’T place
•Bathrooms, kitchens, shower rooms, garages or other rooms where the alarm may be triggered by steam, condensation, normal smoke or fumes. Keep at least 6 metres away from sources of normal smoke/fumes.
DON’T place Heat Alarms in any of the following areas:
•Bathrooms, shower rooms or other rooms where the unit may be triggered by steam or condensation.
DON’T place
•Places where the normal temperature can exceed 40°C or be below 4°C (e.g. attics, furnace rooms, directly above ovens or kettles etc.) as the heat/steam could cause nuisance alarms.
•Near a decorative object, door, light fitting, window moulding etc., that may prevent smoke or heat from entering the unit.
•Surfaces that are normally warmer or colder than the rest of the room (e.g. attic hatches). Temperature differences might stop smoke or heat from reaching the unit.
