Maintenance
The smoke alarm is largely maintenance free ex-
cept for changing the battery. When a tone starts
sounding once every minute, the battery is nearly
dead and needs to be replaced immediately.
This warning continues for a period of 7 days
before the battery is completely discharged.
After this, there is no more power supply.
