I woke up to a false alarm from my smoke detectors this morning. They also went off twice yesterday afternoon. My house was built in 2019, and this has been happening often lately, so I replaced all my smoke detectors. The new ones are a mix of ionization and photoelectric types and have a sealed 10-year battery. They are interconnected (FirstAlert, while the old ones were Kidde). Since then, they’ve mostly worked well.
I think the issue might be voltage fluctuations in the power lines because my cheap LED bulbs flicker a lot, which suggests “unclean” power. Has anyone else had this problem? Any suggestions on how to fix it? I want the system to be reliable so my kids take the alarms seriously. I have a Honeywell Vista alarm panel and thought about converting the 120V alarms to a low-voltage system that ties into the alarm panel. This might fix the power issues, but it’s not a simple task. What other options do I have?
