Do bugs like fire alarms?
Insects, spiders, and other little bu ggy crawly things love the small, dark, hidden spaces in electronics that give off a little bit of heat as they operate. Crawlies especially like fire alarms since they’re on the ceiling where they can live out of the way and uninterrupted. They sometimes crawl into the area with the sensors and set off the alarm.
Why does my smoke detector have a false alarm?
The most common reasons are the following: Presence of dust – the ionization type of smoke detector is the one that frequently experiences false alarms due to dust. When excessive dust gets inside the smoke alarm’s detection chamber, it can mistake it as smoke and trigger the alarm.

What type of smoke detector is used to detect smoke?
There are actually three types of smoke detectors you can choose from, and these are: Photoelectric or optical smoke detector – comprised primarily of a photoelectric sensor and a light beam that shines away from this sensor, this type of alarm uses to light to detect smoke.
How does a smoke detector work?
Once smoke goes inside the detection chamber of the smoke detector, the light beam will scatter and this will trigger the smoke detector to activate. This type of smoke alarm works faster than the ionization type for smoke that come from smoldering materials or sources.
Where should smoke detectors be installed?
The recommendation of the NFPA is that smoke detectors must be installed in the following areas: One for every bedroom. One outside the sleeping area or every hallway. On every floor.
