8.6 Smoke Alarm Automatic Self-Test
The smoke chamber in the Smoke
Alarms automatically tests itself every 16
seconds. If the chamber is degraded it
will beep twice every 48 seconds with
2 yellow LED flashes at the same time.
If this happens clean the unit. If the
beeping persists and the beep does
not coincide with a yellow light flash,
return the unit for service (see Section 5 -
Getting Your Alarm Serviced).
