Panel Differences
The ID60 Panel differs from the ID50 Panel in that it
supports Very Intelligent Early Warning (VIEW
This appendix describes the configuration requirements
of these sensors when used with the ID60 Panel. The
addition of these sensors does NOT affect the panel
installation or commissioning.
When VIEW sensors are configured some additional
TM
menu options become available.

TM
VIEW Sensitivities
VIEW sensors are able to detect very small amounts
TM
of smoke resulting from an incipient fire, such as
smouldering wiring insulation. Because VIEW
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, either by the
TM
Offline Configuration program or at the Panel, 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 at left 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.
