Table 1: Detector LED Modes
Built-In Drift Compensation
The detector automatically adjusts its sensitivity back to the factory setting when it becomes more sensitive due to
contaminants settling in its chamber. In order for this feature to work properly, the chamber must never be opened while
power is applied to the smoke detector. This includes cleaning, maintenance, or screen replacement.
LED Operation
After power-up has completed and the detector is
functioning normally within its listed sensitivity range, the
Green LED blinks once every five seconds.
If the detector needs maintenance because its sensitivity
has shifted outside the limits, the Red LED blinks once
every five seconds. See Table 1.
The LED indication must not be used in lieu of the tests
specified under Testing.
