If the alarm system sounds, the latching alarm indicator will visually identify the unit that initiated the alarm.

The detectors batteries should be replaced regularly and alarms themselves should be replaced at least every 10 years.

The low battery and end-of-life warnings will help notify you when its time to replace the 8th generation detector.
