If you know which sensor is causing the nuisance alarm, change the alarm at that location with another alarm that is not sounding. Give a number to the smoke alarm that causes the nuisance alarm and create a log. In this way, one can determine whether it is the alarm or the location that is the problem.
To investigate further:
a. Does the problem continue at a new location, i.e., it follows the alarm, if so, please contact the supplier / retailer from where you purchased the alarm.
b. If the problem continues at the same location with another alarm, there is something that affects it. It should then perhaps be moved.
