False alarm; loud pulsating alarm sound:

A false alarm, after a period of proper functioning, is mostly caused by dust (particles) in the smoke chamber, or wrong location of the smoke alarm.

It is very important a smoke alarm is maintained properly from the day of installation. If you do not do this, the smoke chamber will gradually contaminate, and as soon as the contamination reaches a certain level, the smoke alarm will start giving a faulty alarm. This is not covered by the warranty as it is caused by poor maintenance.

If contamination of the smoke chamber is causing the faulty alarm, what you can try is to thoroughly vacuum clean your smoke alarm on all visual openings. To avoid faulty alarm it is recommended to do this at least once a month. You do not have to remove the smoke alarm from the ceiling, it is enough if you vacuum clean the outside of the smoke alarm using the vacuum cleaner.

If this does not help the last possible solution is the use of compressed air.

Unfortunately, if this also does not help, the smoke chamber contamination is so deep that it is beyond repair and the smoke alarm will have to be replaced.
