Here is the response I received back from FA:
The issues we’ve been facing is if there is a power malfunction (failure or flicker), sometimes these alarm would fall in some sort of failure mode (solid red light lit instead of solid green). The lights can be reset by pushing hush button usually. And they would randomly activate for no apparent reasons.
– It depends on what you mean by activate – chirp or full alarm. If it is full alarm, it is usually the result of contamination in the photo chamber. On units we have checked with this complaint most often it is drywall dust that was likely ingested because of installation before drywall sanding was finished.
The only way they come back in “normal” mode (solid green light on) is to unplug the AC power, remove the batteries for a little while, and then re-install the batteries and re-connect to AC power. In my opinion this encourages people to disconnect their alarms and maybe no re-install them…”
– We have had to educate contractors on how to properly power up upon initial activation. This can also happen after battery replacement. MOST of the problem is improper power-up.
