Note that there are a few manufactures who do make detectors for a wider range of temperatures i e.
Alarm going off in attic.
If they settled inside the detection chamber of your unit don t be surprised to hear your smoke alarm going off as often as every 10 minutes or so.
Attics and garages both reach temperatures that are outside the range limitations of most smoke alarms.
They sometimes crawl into the area with the sensors and set off the alarm.
Issues with the current load wired smoke alarms are sometimes set off when you use appliances that have heavy current loads in the same circuit especially when there are issues with how it is wired in terms of its proximity to a circuit box.
So i wake up i get ready and when i go downstairs for breakfast an alarm like sirens go off really loudly in the attic when i opened it and went upstairs to check it randomly stopped.
They will go from 15 to 200 degrees fahrenheit.
Smoke alarms are more subject to particles and contamination.
Crawlies especially like fire alarms since they re on the ceiling where they can live out of the way and uninterrupted.
When i checked it said keybus fault call for service i understand the beeping sound but what about the siren sounds.
