Set the sensitivity of the detector using the sensitivity switch (Figure 10) and
digital display. Use the chart below to determine which setting is acceptable
(per UL 268) for your installed distance. Before attempting to set the sensitivity,
make sure that you have completed the fine adjustment process (the
digital display should be “OFF”). To set the sensitivity, depress the sensitivity
button once. The digital display will illuminate and read the current sensitivity
setting as indicated on the chart. Continue to depress the sensitivity
button until the desired setting is achieved. The display will turn off automatically.
The default sensitivity will be factory set at level 4 or 50%.
