We were told basic stupid advice, like make sure you replace your batteries with new batteries, all 3 AAA, each time. The alarm company will allow a pass on the alarm for 3 days max. Too many false alarms, they start charging for each one. Then the alarm company calls the fire department, who come to our home for a false alarm. The alarm company calls or texts my phone, which I can not carry with me while I am with patients. The alarms go off, notify the alarm company. My wife and I work in a medical office, and can not just leave our patients to go home and turn off the alarms. The alarms have been going off since January, and sometimes only during the day, when we are not home. Other times it says they are tampered with. Sometimes the alarm says there is a low battery. We have at least 10 of these alarms throughout the house, and they all will intermittently start going off.
These are 2GIG-SMKT3-345 smoke detectors, manufactured date 2014, and expiration date 2024. In 2017, I had the replace the smoke alarms with new smoke and heat detectors that met the updated county codes.
