entering the Smoke Alarm. Keep at least 0.30m away from walls and corners (see figure 5).

4.2 Wall Mounting

When a ceiling position is not possible (for example on a ceil- ing having exposed beams or joists, or built-in radiant heat- ing) put the top edge of your Smoke Alarm between 0.15m and 0.30m below the ceiling. Keep at least 0.30m from cor- ners (see figure 5).

4.3 On a sloping Ceiling

In areas with sloping or peaked ceilings install your Smoke Alarm 0.90m from the highest point measured horizontally (see figure 6), because “dead air” at the apex may prevent smoke from reaching the unit.

4.4 Locations to Avoid

Don’t place your Smoke Alarm in any of the following areas:

•Bathrooms, kitchen, shower rooms, garages or other rooms where the smoke alarm may be triggered by steam, condensation, normal smoke or fumes.

•Attics or other places where extremes of temperature may occur (below 4°C or above 40°C).

•Near a decorative object, door, light fitting, window molding 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 or battery replacement.

•Locate unit at least 1.5m away from fluorescent light fittings as electrical “noise” and/or flickering may affect the unit.

•Locate away from very dusty or dirty areas as dust build-up in the chamber can make unit too sensitive and prone to alarm.
