1.
Smoke sensor sensitivities are set and continuously monitored by the control
unit. The sensitivity range (setting) for the 4098-9714 and 4098-9754 sensor
is 0.2%/FT to 3.7%/FT smoke obscuration. The sensitivity range (setting) for
4098-9717 sensors is 0.5%/FT to 1.3%/FT.
2.
The 0.2%/FT, 0.5%/FT, and 1.0%/FT settings for the 4098-9714 and 4098-9754
sensor and the 0.5%/FT and 0.9%/FT settings for the 4098-9717 sensor are for
special applications only. The 0.2%/FT, 0.5%/FT, 0.9%/FT, and 1.0%/FT
settings are very sensitive settings: only use the 0.2%/FT setting when a
sensor is located in a totally smoke-free and controlled temperature
environment, such as a computer room or telephone switching exchange.
3.
To determine if an area is suitable for the 0.2%/FT setting, set the sensitivity
for the installed sensor at 1.5%/FT and monitor the peak values for 90 days.
If you record a peak value of 0.1%FT or higher during the 90 days, do not
use the 0.2%/FT setting.
4.
To determine if an area is suitable for the 0.5%/FT setting, set the sensitivity
for the installed sensor at 1.5%/FT and monitor the peak values for 90 days.
If you record a peak value of 0.25%FT or higher during the 90 days, do not
use the 0.5%/FT setting.
5.
To determine if an area is suitable for the 0.9%/FT or 1.0%/FT setting, set
the sensitivity for the installed sensor at 1.3%/FT (ION)/ 1.5%/FT (Photo)
and monitor the peak values for 90 days. If you record a peak value of
0.5%FT or higher during the 90 days, do not use the 0.9%/FT (ION) or
1.0%/FT (Photo) settings.
All sensors identified in Table 5 mount to a sensor base (refer to the 4098
TrueAlarm Bases section of this publication for more information). Use the
following notes and Figure 3 when mounting TrueAlarm sensors.
