AMBIENT LIGHT SENSING
This alarm samples the ambient light conditions of its location and, if possible, determines a Night/Day
cycle. A valid Night/Day cycle will delay alarm chirps during the night until the next Day cycle begins.
When chirping begins during the next Day cycle, you can temporarily silence End of Alarm Life or Network
Error chirps by pressing the Test/Hush button. Low Battery chirps cannot be silenced.
If a valid Night / Day cycle has not been established because the alarm is located in either a constantly dark
or lighted location, the chirps mentioned above will not be delayed at night. Moving the alarm to a different
location might allow the alarm to determine a valid Night / Day cycle.
WARNING: REPLACE ALARM AS SOON AS POSSIBLE WHEN IN END OF ALARM LIFE OR LOW
BATTERY MODE.
