2. When the LED flashes red, place the magnet near
the "T" again.
3. Hold the magnet against the "T" on the detector
base until the green LED flashes twice and the red
LED repeats the sensitivity indication. This turns
on the CleanMe feature.
4. The LED flash sequence is as follows:
a.
single flash green LED
b.
double flash green LED
5. To disable CleanMe, repeat this process and verify
the double flash returns to a single flash.

Magnet operation/sensitivity mode
The F220P Series Detectors feature a unique magnet
operation/sensitivity test. Test the detector by placing
the magnet next to the "T" marked on the detector
base for three consecutive flashes to cause an alarm. If
the magnet is there for less than three flashes and more
than one flash, the detector goes into Sensitivity Mode.
Table 2 describes the different LED flash rates for the
Sensitivity Mode.

The LED sensitivity flash procedure
1. Briefly place the magnet at the "T" on the detector
base for at least one red LED flash but less then
three LED flashes.
2. Wait for the first single green LED flash.
3. Count the number of red LED flashes that follow.
This indicates the sensitivity.
