The AFE offers high ambient light rejection and reduces power consumption to support longer battery life.

The two LEDs help reduce false alarms often caused by steam and dust.


False alarms are a leading factor in detectors being removed or disabled by consumers.


According to the National Fire Protection Association, nearly one in four deaths (23%) in the United States occurred where smoke detectors were not working or disabled..
