My house has hardwired smoke alarms. The one in my parents' bedroom has been false alarming all morning, which means that all five detectors in the house are screaming (because hardwired detectors will all sound when one detects smoke). You can tell which detector it is because of the red flashing light.
We can "hush" the detector for 10 minutes, but it seems to still be getting set off somehow. No space heaters are on anywhere in the house. No walls are warm, the ceiling isn't warm. The HVAC is off and was all night, so it isn't dust from the vents. All the power strips are operating normally and the outlets in the entire house are all only a year old and nothing is malfunctioning except the detector.
We called the local FD and they just came by, told us to press the button, and left. They didn't even check if the attack crawlspace had a fire that we couldn't notice yet.
What the actual fuck is going on?
