the start of the self-test sequence.
• First, the yellow and green lights will
flash briefly—this is normal.

a pause, then 4 beeps. The red light will
flash quickly.
The alarm sequence should last 5-6 seconds.
If it does not alarm, make sure the battery is
correctly installed, and test it again. If the unit still
does not alarm, replace it immediately.
