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.
NOTE! When a CleanMe signal is sent to a control panel
i that is not CleanMe compatible, the signal may be misinterpreted 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 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.
4.4Flash 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.
