PERFORMANCE CHARACTERISTICS

The fundamental parameter used to define the sensitivity of
an optical smoke detector is the level of smoke which will
just produce an alarm under ‘ideal’ conditions. This
parameter, known as the response threshold value, is
normally measured in a smoke tunnel and is defined in
terms of the obscuration produced by the smoke over a one
metre path. The response threshold value is normally given
in dB/m, (or % per m).
