How often should smoke detectors be cleaned?
Once every six months, we recommend that you clean your smoke detectors.

To vacuum out the unit, you should follow your manufacturer’s recommendations for routine cleanings.
Why do my smoke alarms keep going off for no reason?
They’re triggered by foreign objects interacting with parts inside the detectors. This means that anything that can float into your smoke detector, like vapor, steam, smoke and large puffs of dust, can trigger your smoke detector.

Can dust trigger a smoke detector?
Dust/Dirt — Along with smoke, this is another common cause for a false alarm. Photoelectric smoke detectors can mistake dust in or around the device as smoke because dust particles, like smoke particles, can reflect light. Humidity – The density from the moisture in the air can trigger a false alarm.
How can you tell if a smoke detector is bad?
Check the date
- Remove the smoke detector from the ceiling.

- If it’s less than 10 years old, put the smoke detector back on the ceiling or wall.
Do I need an electrician to replace hardwired smoke detectors?
They are hard-wired into our electrical system, but that doesn’t mean you need an electrician to replace them. Modern hard-wired smoke detectors don’t have wires in the back that need to be connected to loose wires in the ceiling.
