Smoke detector
Installation requirements (DFS8M & DF8M)
Smoke rises towards the ceiling, then spreads out horizontally, therefore the ideal place
to fix the sensor is in the middle of the room.
Locations to avoid:
•
Bathrooms, kitchens, shower rooms, garages or other rooms where the smoke
sensor may be triggered by steam, condensation, normal smoke or fumes. Keep at
least 6 m away from sources of normal smoke/fumes
•
Locate away from very dusty or dirty areas as dust build-up in the chamber can
impair performance. It can also block the insect screen mesh and prevent smoke
from entering the smoke detector chamber
•
Do not locate in insect infested areas. Small insects getting into the smoke detector
chamber can cause intermittent alarms
•
Places where the normal temperature can exceed 40°C or is below 0°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 molding etc., that may prevent
smoke or heat from entering the sensor
•
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
•
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 (e.g. over stairwells) where it may be difficult to reach
the alarm (for testing, hushing or battery replacement)
•
Locate the unit at least 1 m from dimmer controlled lights and wiring as some
dimmers can cause interference
•
Locate unit at least 1.5 m from fluorescent light fittings as electrical noise and/or
•
flickering may affect the unit
