SimpliSafe's Smoke Detectors use photoelectric sensors, meaning they detect smoke through the distortion of a light beam inside the detector. Photoelectric smoke detectors will detect smoke faster than other detector types but can occasionally result in a false alarm. False alarms often occur when the device detects other particles in the air. Common false alarms are typically due to excess steam from a bathroom or kitchen, dust build up inside the sensor, or (rarely) a tiny bug finding its way inside.

You can prevent false alarms by cleaning the device once a month:

Make sure to remove the battery before cleaning
Open the cover and vacuum the dust off the sensing chamber at least once a month
Replace the battery after cleaning
Test the smoke detector to make sure the battery is working correctly

Vacuuming the device monthly should prevent dust or debris build-up, and is an especially good idea after you have experienced a false alarm. Also, make sure to install the smoke detectors away from anything that will produce steam. If you are having multiple false alarms and the tips described in this article didn't help, give our customer service line a call for assistance!
