4.3 Set 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.
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 19). 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 19).
4. Hold the magnet against the T mark on the mounting skirt
(refer to Figure 4.2, Item 8 on page 19) 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.
4.4 Flash Rate and Trouble Indication
These detectors include the Chamber Check Automatic Trouble
Indicator that verifies the detector’s calibration is within the
factory listed range. NFPA guidelines for sensitivity testing can
be met by visually inspecting the detector and checking the
flash rate of the LED.

NOTE! When a CleanMe signal is sent to a control panel
that is not CleanMe compatible, the signal may be
misinterpreted as an alarm.
