Auto-Calibration
After first installation, the Smoke Detector will perform auto-calibration after 4 hours. Afterwards it will perform
auto-calibration once every month. During the auto-calibration process, the Smoke Detector will not emit any
sound. Each calibration sampling process takes 2 minutes, if the process fails, it will be retried for a maximum
of 5 times. If the 5
th
retry fails, the LED will flash rapidly and the Smoke Detector will send calibration failure
code to the Control Panel.
The LED flashing can be cancelled by removing and reloading the batteries, or manually starting the
calibration process. However if the manual calibration fails again, the Smoke Detector will emit continuous
beeps. In this case you need to remove and reload the batteries to stop the beeping sound (please wait for 30
seconds after removing batteries before reloading them).
<NOTE>
When auto calibration fails, the smoke alarm function will still work normally using previous alarm threshold
value.
