Notifier FSB-200(A)/-200S(A) - Manual (Page 2)

Page 2 of 4 — DN-6985:C • 11/16/09
Test/reset features:
• Integral sensitivity test filter (FSB-200S only, requires
external power supply).
• Sensitivity filter (incremental scale on reflector).
• Local alarm test switch.
• Local alarm reset switch.
• Remote test and reset switch (compatible with RTS151 and
RTS151KEY test stations).
Smoke Detector Spacing: On smooth ceilings, 30 – 60 feet
(9.1 to 18.3 m) between projected beams and not more than
one-half that spacing between a projected beam and a
sidewall. Other spacing may be used depending on ceiling
height, airflow characteristics, and response requirements.
See NFPA 72.

SENSITIVITY SELECTION
The detector has six sensitivity selections (sensitivity settings
are a feature of specific control panels). Each of these
selections is only acceptable over a specific distance
separation between the detector and the reflector per UL 268.
The chart below determines which selections are acceptable
for your installed distance. The sensitivity of the detector can
be set only when the housing is removed and the detector is
not in the fine adjustment step of the alignment mode,
indicated by the illumination of the dual digital display. To set
the sensitivity, depress the sensitivity button one time. See
Switch Locations diagram. Once the switch is pressed, the
digital display will illuminate and read the current sensitivity
setting in percent obscuration. To change the sensitivity,
continue to depress the sensitivity switch until the desired
setting is achieved. The digital display will turn off
automatically if no further switch presses occur.
In addition to the four standard sensitivity selections, the
detector has two Acclimate® settings. When either Acclimate®
setting is chosen the detector will automatically adjust its
sensitivity using advanced software algorithms to select the
optimum sensitivity for the environment. The sensitivity will be
continuously adjusted within the ranges specified in the chart
above.
Total obscuration can be converted to percent per foot,
assuming uniform smoke density for the entire length of the
beam. The chart below converts total obscuration percent per
foot for all acceptable sensitivity settings.
