To reset a hardwired unit with a battery backup, perform the following steps: Remove the smoke alarm from the mounting bracket and disconnect the power. Remove the battery (for a sealed-battery model, see Battery Settings for a 10-Year Alarm to learn more). Press and hold the test button for five seconds. Reconnect the power and reinstall the ...

It doesn't take a lot of smoke to trigger the alarm. If your smoke detector is within 10 feet of a cooking appliance such as your stove, toaster, or toaster oven, then this may be the cause of your false alarms. Some of the more high-tech photoelectric smoke detection devices (i.e. the Vivint Smoke Detector) are even capable of detecting a sudden r...
Does your smoke detector taunt you every time you slightly overcook your food? This could be a problem that has to do with your smoke detector sensitivity. If your alarm is installed more than 10 feet away from your cooking appliance, but it still sounds every time you crisp your toast, you may want to test and adjust the sensitivity of your alarm....
High humidity carries dense moisture particles that your smoke detector may confuse for smoke particles. In extreme cases, the air is dense enough to scatter the light beam of a photoelectric sensor or cling onto the ions in an ionization chamber. The same concept applies to steam. So, if your smoke detector sits right outside a steamy bathroom, yo...
Take a look at your smoke detector. Do you see the chamber entrances where smoke can enter? They’re just big enough to fit a small insect. Once inside, insects can set off the alarm by interfering with the sensors. You may want to open up your smoke detector to see if there’s a pesky nuisance crawling around inside.
A buildup of dust can also affect your smoke alarm For this reason, experts recommend cleaning your smoke detectors with a vacuum brush attachment at least once a year–if not more.
A common issue is faulty door and window sensors. These can be triggered by loose fittings and register as "open" even when secure. Test these sensors regularly and tighten them as needed. Worn-out batteries can also cause sensors to send incorrect signals. Set up a battery replacement schedule to avoid this.

- Outdated or old security equipment. If it’s been awhile since your security system was installed and you’re experiencing a lot of false alarms, your equipment may need to be replaced.
Power Failures and Loadshedding. Power failures, and the impact of loadshedding, are the one of the most common causes for false alarms. There is a need for additional power supplies and bigger battery kits as we find loadshedding is pushing alarm systems’ battery backup capabilities beyond what they were originally designed to handle.
