Sensor False Alarms
We have had two situations where the siren was activated and there were no intruders, no one was caught on external cameras, no door or window open, nothing that should have trigger the siren. Yet twice we were woken up in the dead of night with the siren blaring. The first time we called the police and they checked the basement where the system said the alarm was triggered. Nothing. Door, storm door and windows still locked, no sign of tampering, no one on camera. Last night the siren was triggered again and after stalking through my home with my weapon, the door that triggered the siren was closed, the storm door still locked, the entry door still locked, latched, secure, no sign of tampering. Nothing on cameras. There was no reason for the siren to be triggered. What is happening? Thanks for any clues I can get.

Hello @Citizen ,
It sounds like something is triggering false alarms on your system. You mention two different situations where this happened - do you know if these alarms were triggered by the same sensor or different sensors?
The Entry Sensor on your door that triggered this alarm last night, does it happen to be placed on a metal surface? We do not recommend putting either part of the Entry Sensor on metal, as it can cause the sensor to demagnetize and make the system read the incorrect open/closed state. If this sensor is on a metal surface, it can help to place a buffer between the door and the sensor; you can use anything like a piece or cardboard or an additional layer of adhesive.
Entry Sensors can also cause false alarms if the sensor and magnet are further than 2 inches apart. As the weather is beginning to get cooler - which can cause houses to shrink - I would check this Entry Sensor to make sure both pieces are still close together.
