Wall mounting (Ei146e only)
If ceiling mounting is impractical,
only
the Ei146e Optical
Smoke Alarm may be mounted on a wall, provided that:
a) the top of the detection element is between 150mm
and 300mm below the ceiling (see Figure 2);
b) the bottom of the detection element is above the level
of any door openings;
Wall mounting should only be considered where close
spaced beams or similar obstructions may preclude
ceiling mounting. It is considered to be the responsibility
of the installer/client to determine if the presence of
asbestos in the ceiling material would make ceiling
mounting ‘impractical’.
Sloping Ceiling
With a sloping or peaked ceiling install a Smoke Alarm
within 600mm of the peak (measured vertically) and a
Heat Alarm within 150mm.
If the height of the peak is less than 600mm in the case
of Smoke Alarms or 150mm in the case of Heat Alarms,
it is regarded as being flat. (see Figure 3).
