4.3Set CleanMe Feature
The Clean Me feature monitors the smoke chamber’s sensitivity and sends a trouble signal to the control panel when the sensitivity degrades to a preset level.

i that is not CleanMe compatible, the signal may be misinterprted as an alarm.
To activate the CleanMe feature:
1.Put the detector into sensitivity mode by placing a magnet next to the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 21). Remove the magnet after the first red LED flash and before the third red LED flash.
2.When the magnet is removed, the LED flashes green once and shows the first of two sensitivity displays.
3.When the LED next flashes red, replace the magnet near the T mark (refer to Figure 4.2, Item 8 on page 21).
4.Hold the magnet against the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 21) until the green LED flashes twice and the red LED repeats the sensitivity indication.
5.The detector exits sensitivity mode. If CleanMe has been successfully enabled, the green LED flashes twice in rapid succession every eight seconds indicating that CleanMe is
activated.
To disable CleanMe, repeat this process and verify the double flash returns to a single flash.
