The
ID61/62 Panel
also supports Very Intelligent Early
Warning (VIEW
TM
) sensors and co-operative multi-sensing
for the following device types: ION, OPT, MLT, OPX/SM2,
SM3 and SM4. This appendix describes the configuration
requirements of these sensors when used with the ID61/
62 Panel. The addition of these sensors does NOT affect
the panel installation or commissioning.
Note:
For more information about VIEW
TM
sensors refer

TM
Application Guide (ref. 997-198).
VIEW Sensitivities
When VIEW
TM
sensors are configured some additional
menu options become available.
VIEW
TM
sensors are able to detect very small amounts
of smoke resulting from an incipient fire, such as
smouldering wiring insulation. Because VIEW
TM
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
TM
sensors can be configured, either by the
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 higher.
