Low battery mode
When the battery is running low, the smoke alarm will indicate
this with a repetitive beep and flash for approximately 30 days.
WARNING:
This smoke alarm is equipped with a non-
replaceable battery. When this warning occurs, replace the
device as soon as possible! The low battery warning beep
can be hushed for 10 hours by pressing the test/hush button.
This feature allows you time to change the smoke alarm. The
smoke alarm will continue to function as normal in this mode.
Fault warning mode
When the smoke sensor is not functioning properly, it will turn
into the fault warning mode. Try cleaning the smoke alarm (see
paragraph maintenance) or replace the smoke alarm. If the
buzzer is not working correctly, the device will turn into the
buzzer fault warning mode. Please immediately replace the
smoke alarm when this occurs.
Night mode
This smoke alarm has an automatic night mode. In dark rooms,
the LED signal will be turned off to prevent disturbance of the
night’s sleep.
