3.2.1.1 VIEW, MULTI and SMART Sensors
VIEW™ Sensors
Very Intelligent Early Warning (VIEW™)
sensors are able to detect very small amounts
of smoke resulting from an incipient fire, such
as smouldering wiring insulation. Because
VIEW™ sensors have an enhanced sensitivity
and the ability to discriminate between
airborne smoke and dust particles, a
representatively narrower percentage band,
expressed as a ‘percentage per metre
obscuration’, is used to set their sensitivity than
is used on other types of sensors.
Note: The term ‘percentage per metre
obscuration’ describes the smoke
saturation level per unit volume of air.
Normal sensors typically detect a fire
condition between 3%/m and 5%/m
obscuration.
VIEW™ sensors can be configured using nine
sensitivity thresholds for pre-alarm and alarm.
Level 1 (L1) is the most sensitive and level 9
(L9) the least sensitive. Pre-alarm can be
disabled by selecting level 0 (L0).
The diagram shows smoke obscuration for
each of the nine level selections. The standard
sensitivity is set at 2.44%/m (L8) or less, high
or enhanced sensitivity is between 2.44%/m
(L8) and 0.98%/m (L5) and very high
sensitivity is 0.98%/m (L5) or lower %/m.
